Improved accuracy of spectral-domain optical coherence tomography and optical coherence tomography angiography for monitoring myopic macular neovascularisation activity. Br J Ophthalmol 2024:bjo-2023-323374. [PMID: 38729765 DOI: 10.1136/bjo-2023-323374] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2023] [Accepted: 04/18/2024] [Indexed: 05/12/2024]
Abstract
BACKGROUND/AIMS To evaluate the diagnostic accuracy of spectral-domain optical coherence tomography (SD OCT) combined with OCT angiography (OCTA) for myopic myopic macular neovascularisation (MNV) activity. METHODS Both eyes of patients with myopic MNV diagnosed with fluorescein angiography (FA), SD OCT and OCTA were assessed by unmasked investigators. The images were deidentified and randomised before graded by masked investigators, who determined the presence of active myopic MNV by using SD OCT together with OCTA without FA and by FA alone, respectively. The findings of masked investigators were compared with unmasked investigators. RESULTS 213 eyes of 110 patients comprising 499 imaging episodes were eligible for grading. For diagnosing new-onset myopic MNV without FA, combined use of SD OCT and OCTA had a sensitivity of 0.94, specificity of 0.84 and area under the curve (AUC) of 0.92. FA had a sensitivity of 0.52 (p<0.01), specificity of 0.80 (p=0.38) and AUC of 0.66 (p<0.01). For recurrent myopic MNV, the combination of SD OCT and OCTA had a sensitivity of 0.98, specificity of 0.78 and AUC of 0.88. FA had a sensitivity of 0.50 (p=0.04), specificity of 0.76 (p=0.85) and AUC of 0.63 (p=0.01). Myopic traction maculopathy was more frequently associated with recurrent myopic MNV (p<0.01). CONCLUSION SD OCT with dense volumetric scan was highly sensitive for diagnosing myopic MNV. The addition of OCTA improved the diagnostic specificity without FA. Monitoring of the longitudinal changes on SD OCT and judicious use of FA is a reliable surveillance strategy for myopic MNV.

Eye (Lond) 2024; 38:792-797. [PMID: 37813979 PMCID: PMC10920795 DOI: 10.1038/s41433-023-02780-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2023] [Revised: 09/18/2023] [Accepted: 09/25/2023] [Indexed: 10/11/2023] Open
Abstract
OBJECTIVE To evaluate the sensitivity and specificity of structural optical coherence tomography (OCT) in comparison to fluorescein angiography (FA) and OCT angiography (OCTA) in discerning between macular haemorrhages (MH) due to myopic choroidal neovascularization (m-CNV) and idiopathic macular haemorrhage (IMH) in myopic patients and to suggest a new OCT biomarker to discern these two entities. METHODS AND ANALYSIS In this longitudinal retrospective study, patients affected by MH and pathological myopia were included. All patients underwent OCTA and FA to discern bleeding from m-CNV or IMH. Furthermore, all patients underwent a structural OCT and 2 expert graders evaluated the presence of the myopic 2 binary reflective sign as a biomarker to discern between IMH and bleeding from m-CNV. RESULTS Forty-seven eyes of 47 patients were enrolled. By means of angiographic examinations, 34 out of 47 eyes with MH (57%) were diagnosed as m-CNV, whereas 13 eyes (43%) as IMH. Using structural OCT, the graders identified the presence of the myopic 2 binary reflective sign in 13 out of 13 eyes with IMH. In 33 out of 34 cases with m-CNV, the 2 graders established the absence of the sign. This accounted for 100% of sensibility and 97% of specificity of structural OCT in discerning between MH from m-CNV and IMH. CONCLUSION Structural OCT can discern with good reliability between IMH and bleeding from m-CNV based on the presence/ absence of the myopic 2 binary reflective sign. This could be of paramount relevance in the clinical setting for the diagnosis and treatment of HM patients.

Case Rep Ophthalmol 2024; 15:335-342. [PMID: 38623407 PMCID: PMC11018332 DOI: 10.1159/000538440] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Accepted: 03/16/2024] [Indexed: 04/17/2024] Open
Abstract
Introduction Severe central visual field defects are frequently observed in highly myopic eyes. This report details 2 cases of central visual field defects in individuals with high myopia, characterized by an unusual temporal protrusion of the optic disc, a feature not previously documented. Case Presentation Two patients, a 54-year-old man and a 65-year-old woman, were diagnosed with high myopia in their left eyes, displaying an outward protrusion of the optic disc toward the macula. Swept-source optical coherence tomography revealed a focal lamina cribrosa defect at the temporal edge of the protruding optic disc, corresponding to the papillomacular bundle area of retinal nerve fibers, which exhibited thinning around the focal lamina cribrosa defect. Visual field examination indicated a central visual field defect in the affected eyes, which pattern corresponded to the papillomacular bundle responsible area. Conclusion The emergence of a temporal protrusion in the optic disc may lead to a focal lamina cribrosa defect, resulting in a central visual field defect in highly myopic eyes. This distinctive optic disc feature may constitute a critical risk factor for a central visual field defect. Hence, optic disc protrusion in high myopia warrants attention, necessitating careful ophthalmic examinations for central visual field defects.

Abstract
Purpose Visual prognosis and treatment burden for macular neovascularization (MNV) can differ between myopic macular degeneration (MMD) and age-related macular degeneration (AMD). We describe and compare MNV associated with MMD and AMD using swept-source (SS)-OCTA. Patients and Methods Adult patients with documented MNV associated with MMD or AMD were consecutively recruited. Qualitative and quantitative features were assessed from 6x6mm angiograms, including the MNV area and vessel density (VD). Descriptive statistics and linear regression analyses were carried out. Results Out of 75 enrolled eyes with diagnosed MNV (30 MMD-MNV and 45 AMD-MNV; mean age 55±19 and 75±8 years, respectively), 44 eyes had discernible MNV (11 MMD-MNV and 33 AMD-MNV) on SS-OCTA at the time of the study and were included in the analysis. The MMD-MNV group exhibited a three-fold smaller sized MNV (p=0.001), lower greatest linear dimension (p=0.009) and greatest vascular caliber (p<0.001) compared to AMD-MNVs, and had a higher prevalence of tree-in-bud pattern. Eyes with AMD showed a higher prevalence of type 1 MNVs with medusa pattern. There was no difference in the location of the MNV, shape's regularity, margins, presence of core vessel, capillary fringe, peripheral loops, or perilesional dark halo (p>0.05) between both conditions. After adjustment, decreased MNV area and increased VD were associated with the tree-in-bud pattern, whereas the diagnosis did not significantly influence those parameters. Conclusion While larger studies are warranted, this study is the first to describe and compare MMD-MNV and AMD-MNV using SS-OCTA, providing relevant clinical insight on MNV secondary to MMD and AMD. These findings also further validate OCTA as a powerful tool to detect and characterize MNV non-invasively.

Abstract
PURPOSE To evaluate the safety and efficacy of intravitreal injections of 0.5 mg conbercept in patients with choroidal neovascularization secondary to pathological myopia (pmCNV). METHODS The 177 pmCNV patients were randomly assigned in a 3:1 ratio to receive conbercept or sham injection, respectively. The conbercept group receive conbercept intravitreal injections administered on a pro re nata (PRN) basis after 3 monthly loading doses. The sham group received three consecutive monthly sham injections and then one conbercept injection followed by PRN conbercept intravitreal injections. RESULTS At month 3, the mean BCVA for the two groups were improved by 12.0 letters (conbercept group, from 54.05 letters to 66.05 letters) and 0.6 letters (sham group, from 49.77 letters to 50.33 letters), respectively (p < 0.001). The mean central retinal thickness (CRT) at month 3 in the two groups decreased 62.0 μm (conbercept group, from 348.90 μm to 286.18 μm) and 4.4 μm (sham group, from 347.86 μm to 343.47 μm) (p < 0.001). At month 9, the mean BCVA improved by 13.3 letters in the conbercept group and 11.3 letters in the sham group. The mean CRT decreased 73.6 μm in the conbercept group and 55.9 μm in the sham group (p < 0.001). The most common ocular adverse events were associated with intravitreal injections, such as conjunctival haemorrhage and increased intraocular pressure. CONCLUSION Intravitreal injections of 0.5 mg conbercept provided improvement in visual and anatomical outcomes in pmCNV patients with low rates of ocular and nonocular safety events.

Abstract
BACKGROUND Several observational studies have reported acute kidney injury from intravitreal anti-vascular endothelial growth factor (anti-VEGF) drugs for retinal diseases. However, systematic reviews and meta-analyses of randomized controlled trials on this critical topic are scant. OBJECTIVE To evaluate acute kidney injury risk associated with intravitreal anti-VEGF drugs in patients with retinal diseases. METHODS We searched PubMed, Embase, and the Cochrane Central Register of Controlled Trials on 12 July, 2023, and included randomized controlled trials reporting acute kidney injury between anti-VEGF drugs (e.g., aflibercept, bevacizumab, brolucizumab, and ranibizumab) and controls for retinal diseases (e.g., age-related macular degeneration, polypoidal choroidal vasculopathy, diabetic retinopathy/diabetic macular edema, retinal vein occlusion, and myopic choroidal neovascularization). Data were synthesized by a fixed-effects model for pooling odds ratios (ORs) using the Peto method. RESULTS We included 13 randomized controlled trials (four and nine trials for aflibercept and ranibizumab, respectively) with a total of 4282 participants. The meta-analysis indicated intravitreal anti-VEGF drugs did not increase the acute kidney injury risk, compared with controls (odds ratio [OR]: 1.00, 95% confidence interval [CI] 0.49-2.04, I2: 0%), and no differences in the acute kidney injury risk were observed between different anti-VEGF drugs (OR: 1.10, 95% CI 0.27-4.43, I2: 0% for aflibercept; OR: 0.97, 95% CI 0.42-2.22, I2: 0% for ranibizumab) and between different retinal diseases (OR: 4.61, 95% CI 0.07-284.13, I2: not applicable for age-related macular degeneration; OR: 0.90, 95% CI 0.42-1.93, I2: 0% for diabetic retinopathy/diabetic macular edema; OR: 1.57, 95% CI 0.16-15.88, I2: 0% for retinal vein occlusion). CONCLUSIONS Intravitreal anti-VEGF drugs were not associated with an acute kidney injury risk, regardless of which anti-VEGF drugs (aflibercept or ranibizumab) or retinal diseases (age-related macular degeneration, diabetic retinopathy/diabetic macular edema, or retinal vein occlusion) were involved.

Abstract
Myopic choroidal neovascularization (CNV) is a vision-threatening complication of high myopia. Here, we systematically review cohort, case-control, and cross-sectional studies in PubMed, Embase, and Web of Science, and summarize the associated factors of myopic CNV using meta-analysis where applicable. Among 1,333 records assessed, 50 were found eligible, all having a low-to-moderate risk of bias. Highly myopic eyes with CNV had a higher risk of lacquer cracks (odds ratio = 2.88) and patchy chorioretinal atrophy (odds ratio = 3.43) than those without. The mean posterior staphyloma height (µm) was greater in myopic CNV eyes than in highly myopic eyes without CNV (mean difference = 82.03). The thinning of choroidal thickness (µm) between myopic eyes with and without CNV differed significantly (mean difference = -47.76). The level of vascular endothelial growth factor (pg/ml) in the aqueous humor of myopic CNV eyes was significantly higher than in highly myopic eyes without CNV (mean difference = 24.98), the same as interleukin-8 (IL-8) (pg/ml, mean difference = 7.73). Single-nucleotide polymorphisms in the vascular endothelial growth factor, complement factor I, and collagen type VIII alpha 1 genes were associated with myopic CNV. We found that myopic CNV eyes have a higher ratio of lacquer cracks and patchy chorioretinal atrophy, thinner choroid, greater posterior staphyloma height, and a higher level of vascular endothelial growth factor and IL-8 in aqueous. Structural predisposing lesions, hemodynamic, genetic, and systemic factors are also associated with myopic CNV.

Abstract
INTRODUCTION The rising prevalence of myopia is a concern in ophthalmology, with myopic choroidal neovascularisation (m-CNV) significantly affecting vision. However, long-term outcomes of m-CNV management have been unsatisfactory, leading to high recurrence rates. These studies aim to identify risk factors for m-CNV recurrence. METHODS Comprehensive review followed a pre-registered plan in the International Prospective Register of Systematic Reviews (PROSPERO). The search strategy used various databases including PubMed, Cochrane Library, Embase, Scopus and ScienceDirect using the keywords 'Myopic Choroidal Neovascularization', 'Recurrence' and 'Risk'. Eligible studies were identified and analysed based on predetermined criteria. This study was registered on PROSPERO (CRD4202343461). RESULTS The systematic review included three retrospective studies investigating risk factors associated with m-CNV recurrence. These factors are: (1) requiring three or more injections for initial disease control, (2) older age, (3) larger myopic macular neovascularisation, (4) juxtafoveal CNV, (5) larger height of hyper-reflective foci (HRF) and (6) destruction or absence of the ellipsoid zone (EZ) and retinal pigment epithelium (RPE). CONCLUSION Risk factors for m-CNV recurrence include a greater number of required injections, older age, large macular CNV, juxtafoveal location, increased HRF height and changes in EZ and RPE structure. Understanding these factors can inform personalised treatment approaches and improve patient outcomes by identifying individuals at higher risk of recurrence and implementing proactive measures to mitigate the impact of m-CNV recurrence and progression. Further investigation is needed to enhance our understanding of the underlying mechanisms and develop innovative therapeutic approaches for effective m-CNV management.

Comparison of antivascular endothelial growth factor treatment for myopia choroidal neovascularisation: a systematic review and meta-analysis of randomised controlled trials. BMJ Open 2023; 13:e067921.

Abstract
OBJECTIVES To evaluate the efficacy and safety of anti-vascular endothelial growth factor (anti-VEGF) therapy for myopia choroidal neovascularisation (CNV), and to compare the efficacy of two different anti-VEGF retreatment criteria. DATA SOURCES PubMed, EMBASE, the Cochrane Library and ClinicalTrials.gov were searched from inception to 31 July 2022. STUDY SELECTION Randomised controlled trials (RCTs) comparing anti-VEGF with sham, photodynamic therapy (PDT) or PDT combination therapy in patients with myopia CNV were reviewed and selected. RCTs comparing visual acuity (VA) stabilisation or disease activity as anti-VEGF retreatment criteria were also included in the study. DATA EXTRACTION AND SYNTHESIS Two reviewers independently conducted data extraction and quality assessment. We used a random-effects model for all analyses. Primary outcomes included best-corrected visual acuity (BCVA) and central foveal thickness. Secondary outcomes included number of patients who gained more than three lines in BCVA, number of anti-VEGF injections and ocular adverse event (AE). RESULTS Seven RCTs involving 1007 patients were included. Compared with sham and PDT therapy, anti-VEGF therapy achieved better BCVA gains of -0.28 logMAR (95% CI -0.36 to -0.20, p<0.00001) and -0.14 logMAR (95% CI -0.17 to -0.10, p<0.00001), respectively. Both ranibizumab and bevacizumab improved patients' vision better than PDT therapy and no definitive increased risk of ocular AE was observed. Analysis of two small RCTs showed that PDT combination therapy had similar visual improvement and needed fewer anti-VEGF injections compared with anti-VEGF monotherapy (weighted mean difference (WMD)=1.30; 95% CI 1.24 to 1.37, p<0.00001). Anti-VEGF retreatment guided by disease activity criteria resulted in comparable visual improvement and reduced anti-VEGF injections compared with retreatment guided by VA stabilisation (WMD=0.83; 95% CI 0.42 to 1.25, p<0.0001). CONCLUSIONS Anti-VEGF therapy is effective and well-tolerated for myopia CNV patients. Anti-VEGF retreatment guided by disease activity criteria can achieve comparable efficacy and potentially reduce anti-VEGF injections. PROSPERO REGISTRATION NUMBER CRD42021292806.

Abstract
PURPOSE To investigate the factors associated with maximum visual improvement (peak vision) gain and the risk factors of peak vision loss and multiple recurrences in myopic macular neovascularization undergoing antivascular endothelial growth factor therapy. METHODS Retrospective study of 310 eyes with active myopic macular neovascularization and median follow-up of 3.5 years. We defined peak vision gain as the maximum best-corrected visual acuity value reached under treatment and peak vision loss as best-corrected visual acuity never scoring as peak vision. We used multiple-event Prentice, Williams, and Peterson models to compute recurrences' incidence and Cox regression to identify risk factors for peak vision gain, peak vision loss, and multiple recurrences. RESULTS Eyes with worse baseline best-corrected visual acuity {hazard ratio (HR) = 2.59 (95% confidence interval [CI]: 1.63-4.11) for 0.1 logMAR increase, P < 0.001} had higher chance to achieve peak vision. Peak vision was lost in 162 eyes (52%). Older age (HR = 1.22 [95% CI: 1.02-1.43] for 10-year increase, P = 0.02) and recurrences (HR = 1.10 [95% CI: 1.01-1.22] for event, P = 0.04) predicted nonsustained peak vision. Older age (HR = 1.13 [95% CI: 1.04-1.27] for 10-year increase, P = 0.006), larger myopic macular neovascularization (HR = 1.06 [95% CI: 1.01-1.13] for 1-mm 2 increase, P = 0.04), and juxtafoveal location (HR = 1.88 [95% CI: 1.28-2.77] vs. extrafoveal, P = 0.001) predicted multiple recurrences. CONCLUSION Myopic macular neovascularization eyes lose vision mainly because of multiple recurrences. Patients at risk for recurrences should undergo more attentive monitoring to avoid vision loss.

Abstract
Recent evidence has demonstrated that the global public health burden of myopia is rising rapidly. Highly myopic eyes are associated with increased frequency of eye disorders that can lead to irreversible visual impairment. With recent technological advancement in ophthalmic imaging modalities, various macular complications associated with pathologic myopia are being elucidated. The development and progression of myopic chorioretinal atrophy, myopic macular neovascularization, myopic traction maculopathy and dome-shaped macula are vision-threatening myopic macular diseases. In order to overcome the challenges in managing patients with pathologic myopia, it is important to have a complete understanding in the natural course of these myopic macular diseases. Standardising the classification criteria of pathologic myopia is essential for enhancing clinical surveillance. Personalised pharmaceutical therapy and surgical interventions will help to optimise the treatment outcomes in patients suffering from these myopic macular diseases.

Abstract
PURPOSE To identify the risk factors associated with myopic macular neovascularization (mMNV)-related complications in patients treated with intravitreal anti-VEGF agents. DESIGN Longitudinal cohort study. PARTICIPANTS Myopic eyes (n = 313) with active mMNV and median (interquartile range) follow-up of 42 months (interquartile range, 18-68 months) after initiation of anti-VEGF treatment. METHODS Data regarding patients' clinical and mMNV-related characteristics were collected at baseline. Subsequent OCT scans were inspected for mMNV-related complications. Best-measured visual acuity (BMVA) values were retrieved from each visit. MAIN OUTCOME MEASURES Incidence rate and hazard ratio (HR, with 95% confidence interval [CI]) of risk factors for fibrosis and macular atrophy calculated with Kaplan-Meier curves and Cox regression models. Crude incidence of macular hole (MH). Longitudinal BMVA changes. RESULTS Five-year incidence of fibrosis, atrophy, and MH were 34%, 26%, and 8%, respectively. The rate of fibrosis was 10.3 (95% CI, 8.25-12.6) per 100 person-years. Risk factors were subfoveal mMNV location (HR [95% CI] = 12.7 [2.70-56.7] vs. extrafoveal, P = 0.001) and intraretinal fluid at baseline (HR [95% CI] = 1.75 [1.05-2.98], P = 0.03). The rate of macular atrophy was 6.5 (95% CI, 5-8.3) per 100 person-years. Risk factors were diffuse (HR, 2.20 vs. tessellated fundus; 95% CI, 1.13-5.45; P = 0.02) or patchy chorioretinal atrophy (HR, 3.17 vs. tessellated fundus; 95% CI, 1.32-7.64; P = 0.01) at baseline and more numerous anti-VEGF injections before baseline (HR, 1.21; 95% CI, 1.06-1.38 for each treatment; P = 0.005). Eyes with fibrosis and macular atrophy had faster BMVA decay over follow-up. Twenty eyes (6%) developed MH. Two subtypes of MH were identified: "atrophic" and "tractional." CONCLUSIONS Myopic MNV-related complications are common in the long term despite initially successful treatment and have detrimental effects on visual acuity. Insights into their incidence and risk factors may help for future treatments to mitigate sight-threatening outcomes.

Abstract
Purpose The study aimed to evaluate risk factors for macular atrophy (MA) associated with myopic choroidal neovascularization (mCNV) during long-term follow-up after intravitreal anti-vascular endothelial growth factor (VEGF) treatment in highly myopic eyes. Methods The medical records of patients who received intravitreal injection of anti-VEGF agents as mCNV treatment and were followed-up for more than 36 months were retrospectively reviewed. The risk factors for the development of mCNV-MA, which is the fovea-involving patchy atrophy lesion adjacent to mCNV, were investigated using the Cox proportional hazard model. Results A total of 82 eyes (74 patients) were included in the study. The mean age at anti-VEGF treatment was 56.3 ± 12.5 years (range, 26–77), and the mean follow-up period was 76.3 ± 33.5 months (range, 36–154). During follow-up, mCNV-MA developed in 27 eyes (32.9%), and its occurrence was estimated to be 24.5% at 3 years and 37.3% at 5 years after the first anti-VEGF treatment. Old age (hazard ratio [HR] = 1.054, 95% confidence interval [CI]: 1.018–1.091; P = 0.003) and greater CNV size at baseline (HR = 2.396, CI: 1.043–5.504; P = 0.040) were significant factors for mCNV-MA development. Eyes with a thinner subfoveal choroid were more likely to show faster enlargement of the mCNV-MA during follow-up. Conclusions In mCNV eyes treated with intravitreal anti-VEGF agents, older age and greater mCNV size at baseline were risk factors for the development of MA during long-term follow-up, which was associated with a poor visual prognosis.

Abstract
Metabolomics analyzes the entire range of small molecule metabolites in biological systems to reveal the response signals that are transmitted from "genetics and environment", which could help us understand complex phenotypes of diseases. Metabolomics has been successfully applied to the study of eye diseases including age-related macular degeneration, glaucoma, and diabetic retinopathy. In this review, we summarize the findings of myopic metabolomics and discuss them from a design and analysis perspective. Finally, we provide new ideas for the future development of myopia metabolomics research based on the broader ocular metabolomics study.

Abstract
Objectives To evaluate incidence, predictors, and re-treatment outcome of recurrent myopic choroidal neovascularization (m-CNV). Methods Retrospective consecutive observational series. From year 2014 to 2019, 167 eyes of 167 patients of treatment naïve m-CNV were enrolled. 59 and 108 eyes were treated with intra-vitreal ranibizumab and bevacizumab mono-therapy, respectively. Recurrence was defined as re-appearance of CNV activity, confirmed on optical coherence tomography (OCT) after at least 3 months of cessation of anti-VEGF therapy. Incidence of recurrence, predictors and re-treatment outcomes were studied. Results Overall, mean age and spherical equivalence (SE) was 47.95 ± 14.72 years and -12.19 ± 4.93 D respectively. Males constituted 50.9%. 44 eyes (26.4%) had a recurrence during a mean follow up of 16.5 ± 12.86 months. Kaplan-Meier survival analysis showed the risk of recurrence was 8, 26 and, 33.6% at 6, 12 and 18 months, respectively. Age (p = 0.511), gender (p = 0.218), SE (p = 0.092), anti-VEGF (p = 0.629) and baseline BCVA (p = 0.519) did not influence recurrence. Number of injections administered to control the disease in the first episode was the only significant predictor of recurrence (Cox Proportional Hazard Ratio 2.89–3.07, 95% Confidence Interval: 1.28–7.45; p = 0.005). At 12 months, eyes requiring one injection in first episode had a recurrence rate of 12% versus 45% in eyes requiring 3 or more injections in the first episode. A mean number of 1.9 additional injections per eye was needed during re-treatment. Final BCVA in the recurrence group was similar to that of non-recurrence group (0.53 ± 0.40 versus 0.55 ± 0.36 LogMAR; p = 0.755). Baseline BCVA (p = 0.0001) was the only predictor of final visual outcome irrespective of anti-VEGF drug (p = 0.38). Conclusion Eyes requiring greater number of injections for disease control in first episode are “at risk” of early m-CNV recurrence. However, recurrence does not adversely affect visual outcome, if treated adequately.

Abstract
To investigate optical coherence tomography (OCT) and OCT angiography (OCTA) biomarkers for good visual outcomes in eyes with myopic choroidal neovascularization (mCNV) following anti-vascular endothelial growth factor (anti-VEGF) therapy. Patients diagnosed with mCNV via multimodal imaging were retrospectively reviewed. Baseline demographic data and biomarkers were collected. Anti-VEGF treatment based on a pro re nata (PRN) regimen was conducted on all eyes. The visual gains of ≥ 15 ETDRS letters or < 15 letters at 12-month were classified into two groups. Regression analysis was used to identify variables associated with significant best-corrected visual acuity (BCVA) improvement. Among 34 patients, 17 eyes and 17 eyes were classified into the two groups. There were no statistically significant differences in qualitative OCTA biomarkers between the two groups. The ≥ 15 letters group had significantly thicker subfoveal choroid thickness (SFCT) (79.97 ± 33.15 vs. 50.66 ± 18.31, P = 0.003), more ellipsoid zone integrity (58.8% vs. 23.5%, P = 0.037) and lower levels of fractal dimension (1.45 ± 0.101 vs. 1.53 ± 0.082, P = 0.031) than the < 15 letters group. SFCT and the ellipsoid zone integrity were correlated with 15 letters or more VA improvement in both univariable and multivariable analyses (P = 0.023 and P = 0.044, respectively). Thicker SFCT and integrity of the ellipsoid zone at baseline were associated with greater visual gains at 12 months. OCTA biomarkers seem to play a less important role in predicting the visual outcome of mCNV.

Abstract
Purpose To develop an artificial intelligence (AI) system that can predict optical coherence tomography (OCT)-derived high myopia grades based on fundus photographs. Methods In this retrospective study, 1,853 qualified fundus photographs obtained from the Zhongshan Ophthalmic Center (ZOC) were selected to develop an AI system. Three retinal specialists assessed corresponding OCT images to label the fundus photographs. We developed a novel deep learning model to detect and predict myopic maculopathy according to the atrophy (A), traction (T), and neovascularisation (N) classification and grading system. Furthermore, we compared the performance of our model with that of ophthalmologists. Results When evaluated on the test set, the deep learning model showed an area under the receiver operating characteristic curve (AUC) of 0.969 for category A, 0.895 for category T, and 0.936 for category N. The average accuracy of each category was 92.38% (A), 85.34% (T), and 94.21% (N). Moreover, the performance of our AI system was superior to that of attending ophthalmologists and comparable to that of retinal specialists. Conclusion Our AI system achieved performance comparable to that of retinal specialists in predicting vision-threatening conditions in high myopia via simple fundus photographs instead of fundus and OCT images. The application of this system can save the cost of patients' follow-up, and is more suitable for applications in less developed areas that only have fundus photography.

Discerning Between Macular Hemorrhages Due to Macular Neovascularization or Due to Spontaneous Bruch’s Membrane Rupture in High Myopia: A Comparative Analysis Between OCTA and Fluorescein Angiography. Ophthalmol Ther 2022; 11:821-831. [PMID: 35184253 PMCID: PMC8927552 DOI: 10.1007/s40123-022-00484-0] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2022] [Accepted: 02/07/2022] [Indexed: 11/11/2022] Open
Abstract
Introduction To evaluate the sensitivity and specificity of optical coherence tomography angiography (OCTA) in comparison to fluorescein angiography (FA) in discerning between macular hemorrhages due to myopic macular neovascularization (m-MNV) and idiopathic macular hemorrhage (IMH) in patients with high myopia (HM). Methods In this retrospective study, 14 eyes of 14 patients (mean age 60 ± 16 years) affected by macular hemorrhage due to HM were included. All patients underwent OCTA and FA at the time of macular hemorrhage (i.e., baseline) and were followed for a 3-month follow-up. Results By means of FA, 8 out of 14 eyes with macular hemorrhage (57%) were diagnosed as type 2 m-MNV, whereas 6 eyes (43%) were diagnosed as IMH. Interestingly, OCTA displayed the presence of a neovascular network in all cases previously diagnosed as m-MNV using FA, and also excluded the presence of anomalous flow in all IMH eyes. This accounted for the high sensitivity and specificity of OCTA for m-MNV detection in HM cases with macular hemorrhage. After 3-month follow-up, BCVA improved from 0.39 ± 0.15 to 0.21 ± 0.14 logMAR (p = 0.006) in patients with m-MNV treated by a mean of 2.3 ± 0.9 intravitreal anti-VEGF injections. Conversely, BCVA improved without treatment (from 0.55 ± 0.48 to 0.17 ± 0.08 logMAR, p = 0.112) in patients with IMH. Conclusions OCTA is able to differentiate with excellent reliability between the presence of m-MNV in patients with HM presenting with a new macular hemorrhage and an IMH. This could be of paramount relevance in the clinical setting for the diagnosis and treatment of patients with HM.

Choroidal Morphologic and Vascular Features in Patients With Myopic Choroidal Neovascularization and Different Levels of Myopia Based on Image Binarization of Optical Coherence Tomography. Front Med (Lausanne) 2022; 8:791012. [PMID: 35059417 PMCID: PMC8764308 DOI: 10.3389/fmed.2021.791012] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2021] [Accepted: 11/29/2021] [Indexed: 12/19/2022] Open
Abstract
Purpose: To characterize the choroidal morphologic and vascular features in different levels of myopes and patients with myopic choroidal neovascularization (mCNV). Methods: A total of 148 subjects were enrolled in this cross-sectional study, including 78 low-to-moderate myopes (LMM), 53 high myopes (HM), and 17 high myopic patients with mCNV. Ocular biometrics were measured using an optical low-coherence reflectometry device. Retinal and choroidal imaging was performed using enhanced depth imaging (EDI) spectral domain optical coherence tomography (OCT). Retinal parameters including retinal thickness and retinal volume were obtained from a built-in software. Binarization technique was adopted to investigate choroidal parameters including choroidal thickness (CT), vascular area, stromal area, and choroidal vascularity index (CVI). Choroidal parameters were measured at five locations to cover as much area of choroid as possible, and their patterns of distribution were further analyzed. Results: Patients with mCNV had an atrophic retina of comparable thickness to HM (273.65 ± 17.28 vs. 276.49 ± 13.29 μm, p = 0.47), but the choroid was thinner than that of HM (153.94 ± 15.12 vs. 236.09 ± 38.51 μm, p < 0.001). Subfoveal CVI was greatest in the mCNV eyes (0.651 ± 0.009), followed by HM (0.645 ± 0.012) and LMM eyes (0.636 ± 0.012). Similar to CT, CVI was also found significantly different among these three groups at all five locations (p for trend < 0.001 for all locations). Axial length (AL) was negatively correlated with retinal volume (r = -0.236, p = 0.009), which is the only significant finding in associations between ocular factors and retinal parameters. Strong, negative correlations were identified between AL and subfoveal choroidal thickness (SFCT, r = -0.820, p < 0.001). However, AL was positively correlated with subfoveal CVI (r = 0.668, p < 0.001). CVI was greater in myopic eyes with thinner choroid (r = -0.578, p < 0.001). BCVA exhibited no significant association with CVI (r = 0.139, p = 0.092), but was negatively correlated with SFCT (r = -0.386, p < 0.001) and positively correlated with AL (r = 0.351, p < 0.001). Conclusion: Choroid in patients with mCNV was thinner yet more vascularized than that in HM and LMM subjects. CVI increased with a longer AL which was associated with a smaller SFCT, choroidal vascular area (VA), and total choroidal area (TCA). Better BCVA was achieved in subjects with thicker SFCT and shorter AL.

Abstract
Purpose: To assess the effect of axial length (AL) on the prevalence of pathologic myopia (PM) and associated myopic features in a Singaporean hospital-based cohort of patient with high myopia (HM). Methods: In total, 923 HM eyes from 495 individuals were recruited from the Myopic and Pathologic Eyes in Singapore (MyoPES) cohort and underwent ocular biometry, fundus photography, fundus autofluorescence, and swept-source optical coherence tomography (SS-OCT). Images were analyzed for the presence of myopic macular degeneration (MMD), myopic choroidal neovascularization (mCNV), myopic traction maculopathy (MTM), peripapillary atrophy (PPA), myopic tilted disc, posterior staphyloma (PS), dome-shaped macula (DSM), vitremacular adhesions (VMA), and the epiretinal membrane (ERM). Eyes were stratified into quartiles based on ALs to determine cut-off values to perform comparisons between shorter-length and longer-length groups. A χ2-test was done to determine the difference in the prevalence of pathologies between groups. Results: Overall, mean AL was 29.2 ± 2.2 mm (range 25.0-36.7 mm). Myopic macular degeneration, PPA, myopic tilted disc, and ERM have AL threshold of ≥27.5 mm, whereas MTM has an AL threshold of ≥29.0 mm. We found that there was a significantly higher prevalence of MMD (88.2 vs. 49.4%; p < 0.001), PPA (98.1 vs. 80.1%; p < 0.001), myopic tilted disc (72.7 vs. 50.2%; p < 0.001), and ERM (81.4 vs. 17.3%; p = 0.003) in eyes with AL ≥ 27.5 mm vs. eyes without AL <27.5 mm. Prevalence of MTM (34.7 vs. 32.1%; p < 0.001), mCNV (17.4 vs. 12.1%; p = 0.03), PS (43.4 vs. 34.7%; p = 0.012), DSM (21.3 vs. 13.2%; p = 0.002), and VMA (5.9 vs. 2.6%; p = 0.014) in eyes with AL ≥ 29.0 mm compared with AL < 29.0 mm. Conclusion: Our study describes the overall prevalence of PM and related pathologies among patients with HM in our hospital-based cohort. Longer eyes even among HM eyes had a significantly higher prevalence of PM-associated pathologies studied. This supports the premise that eyes with longer AL, even among HM eyes may be at greater risk of vision-threatening changes and therefore merit regular follow-up.

Abstract
PURPOSE To study perforating scleral vessels (PSVs) in patients with high myopia using swept-source optical coherence tomography and to determine their relationship with myopic choroidal neovascularization (mCNV) and its activity. METHODS Retrospective analysis of patients with high myopia (≥-6 D or ≥26 mm of axial length) using multimodal imaging. The presence of PSVs and mCNV was assessed using swept-source optical coherence tomography images (TRITON; Topcon Corporation, Japan). RESULTS Five hundred sixty-four eyes from 297 highly myopic patients were studied. One hundred fifty-five eyes (27.5%) showed signs of mCNV while PSVs were found in 500 eyes (88.6%). Perforating scleral vessels were found in 93.5% (145/155) of eyes with mCNV, and they were under or in contact with the mCNV in 80.6% (117/145). The mean number of intravitreal injections received by patients with mCNV was 4.06 ± 4.17 along 66.9 ± 4.1 months of follow-up. The number of injections per year was 1.32 ± 1.56, the mean number of relapses was 1.11 ± 1.83, and the mean number of relapses per year was 0.25 ± 0.41. CONCLUSION Perforating scleral vessels are more common among highly myopic patients suffering from neovascular complications. Myopic CNV complexes that are coincident with PSVs on optical coherence tomography show higher rates of activity, needing more injections to control them and being more prone to relapses.

Abstract
High myopia is an ophthalmic pathology that affects half of the young adults in the United States and Europe and it is predicted that a third of the world’s population could be nearsighted at the end of this decade. It is characterized by at least 6 diopters or axial length > 26 mm and, choroidal neovascularization (CNV) in 5 to 11% of cases. Ranibizumab is a recombinant humanized monoclonal antibody fragment. It is an anti-vascular endothelial growth factor (anti-VEGF) drug used in the treatment of CNV. Many genetic polymorphisms have been associated with interindividual differences in the response to ranibizumab, but these associations were not yet assessed among patients with high myopia and CNV. We performed a retrospective study assessing the association of genetic polymorphisms with response to ranibizumab in patients with CNV secondary to high myopia (mCNV). We included genetic polymorphisms previously associated with the response to drugs used in CNV patients (bevacizumab, ranibizumab, aflibercept, and photodynamic therapy (PDT)). We also included genetic variants in the VEGFA gene. Based on our results, ARMS2 (rs10490924) and CFH (rs1061170) are associated with response to ranibizumab in high myopia patients; and, included VEGFA genetic polymorphisms are not associated with ranibizumab response in our population but might be related to a higher risk of CNV.

Abstract
Although choriocapillaris flow deficit (CFD) around choroidal neovascularization (CNV) is less associated with CNV activity in myopic eyes, no reports are investigating its size as an indicator of CNV activity. We investigated the relationship between CFD and high myopia-related CNV. In this retrospective, observational study, patients underwent optical coherence tomography angiography (OCTA) with split-spectrum amplitude-decorrelation angiography for diagnosing pathological myopic CNV (mCNV); CFD features around CNV margins were evaluated. Of the 33 eyes (30 patients), 11 (33.3%) had active mCNV, and 22 (66.7%) had inactive CNV. Six eyes (18.2%) were treatment-naïve, while the remainder previously underwent anti-vascular endothelial growth factor therapy. On OCTA, blood flow signals were detected in CNV in the outer retinal layer in 28 (84.8%) eyes, including all active cases (11 cases) and 17 (77.3%) of 22 inactive cases. CNV flow signal size correlated significantly with activity (P < 0.001). CFD around CNV was observed in 24 eyes (72.7%), including all active cases (11 cases) and 13 (59.1%) of 22 inactive cases. CFD size correlated significantly with CNV activity (P < 0.001). The size of both the CFD area around CNV and CNV flow signal area are useful indicators of CNV activity in eyes with mCNV, which may help determine treatment timing.

Abstract
Background: Pathologic myopia (PM) associated with myopic maculopathy (MM) and “Plus” lesions is a major cause of irreversible visual impairment worldwide. Therefore, we aimed to develop a series of deep learning algorithms and artificial intelligence (AI)–models for automatic PM identification, MM classification, and “Plus” lesion detection based on retinal fundus images. Materials and Methods: Consecutive 37,659 retinal fundus images from 32,419 patients were collected. After excluding 5,649 ungradable images, a total dataset of 32,010 color retinal fundus images was manually graded for training and cross-validation according to the META-PM classification. We also retrospectively recruited 1,000 images from 732 patients from the three other hospitals in Zhejiang Province, serving as the external validation dataset. The area under the receiver operating characteristic curve (AUC), sensitivity, specificity, accuracy, and quadratic-weighted kappa score were calculated to evaluate the classification algorithms. The precision, recall, and F1-score were calculated to evaluate the object detection algorithms. The performance of all the algorithms was compared with the experts’ performance. To better understand the algorithms and clarify the direction of optimization, misclassification and visualization heatmap analyses were performed. Results: In five-fold cross-validation, algorithm I achieved robust performance, with accuracy = 97.36% (95% CI: 0.9697, 0.9775), AUC = 0.995 (95% CI: 0.9933, 0.9967), sensitivity = 93.92% (95% CI: 0.9333, 0.9451), and specificity = 98.19% (95% CI: 0.9787, 0.9852). The macro-AUC, accuracy, and quadratic-weighted kappa were 0.979, 96.74% (95% CI: 0.963, 0.9718), and 0.988 (95% CI: 0.986, 0.990) for algorithm II. Algorithm III achieved an accuracy of 0.9703 to 0.9941 for classifying the “Plus” lesions and an F1-score of 0.6855 to 0.8890 for detecting and localizing lesions. The performance metrics in external validation dataset were comparable to those of the experts and were slightly inferior to those of cross-validation. Conclusion: Our algorithms and AI-models were confirmed to achieve robust performance in real-world conditions. The application of our algorithms and AI-models has promise for facilitating clinical diagnosis and healthcare screening for PM on a large scale.

Abstract
BACKGROUND Highly myopic eyes differ in morphology from emmetropic eyes, and the correct estimation of the vitreous volume is difficult. To explore an effective method to estimate ocular volume using refractive factors in children. METHODS This is a retrospective study of children with high myopia who visited the Shenzhen Shekou People's Hospital (July-December 2018) before undergoing posterior scleral reinforcement surgery. Data on refractive factors and ocular 3D reconstruction imaging based on high-end CT were collected for linear correlation and linear regression analyses. RESULTS Ten patients (20 eyes) were included. There are nine males and one female. They were 4 to 12 years of age. The spherical equivalent ranges from + 0.25 to -20.00 D. The cylindrical equivalent ranges from - 0.50 to -6.25 D. The AL(axial length, AL) ranges from 21.78 to 33.90 mm. The corneal curvature (mean) ranges from 42.44 to 46.75. The 3D reconstruction of the CT images shows that the ocular volume ranges from 4.591 to 10.988 ml. The ocular volume of the 20 eyes decreases with the increase of diopter and total curvature, both presenting a linear trend, with the Pearson correlation coefficients being - 0.776 (P < 0.001) and - 0.633 (P = 0.003), respectively. The ocular volume of the 20 eyes increases with the increasing AL, also presenting a linear trend, with the Pearson correlation coefficient being 0.939 (P < 0.001). CONCLUSIONS In children, the ocular volume is negatively and linearly correlated with the diopter and curvature, and positively and linearly correlated with the AL.

Abstract
Purpose: To evaluate the incidence of choroidal neovascularization (CNV) in high myopic patients who experienced recent visual loss and to describe the characteristics of CNV that develop as a complication of pathologic myopia and were detected by fluorescein angiography (FA). Material and methods: The fluorescein angiograms of 89 patients with high myopia, who registered a recent decrease of visual acuity were reviewed. The incidence of CNV was evaluated and its angiofluorographic appearance described. Results: 172 eyes of 89 patients (six eyes were excluded for different reasons: anophthalmia, dense cataract, history of retinal detachment surgery) were analyzed. Among 89 patients (63 females, 26 males), in 58 cases (~65%), the angiofluorography revealed the presence of a neovascular membrane, and 8 cases presented bilateral CNV. That made a total of 66 eyes. The majority of CNVs were classic (56%), 20% had an occult pattern and 24% were cicatricial. The location was predominantly subfoveal. Conclusions: Considering that the main cause for visual loss in myopic patients is the new-onset myopic CNV, fluorescein angiography should be performed in cases with recent visual loss. When CNV is suspected, FA can demonstrate the presence of myopic CNV, bringing information regarding the type, area, and activity of the CNV and helping exclude other disorders. Due to its location, predominantly sub- or juxtafoveal and to the extended retinal lesions associated with pathologic myopia, the visual prognosis of these patients is poor despite new active treatments.

Abstract
INTRODUCTION Anti-angiogenesis therapy with intravitreal anti-VEGF agents is now the standard-of-care treatment for myopic choroidal neovascularization (CNV). AREAS COVERED We provide a critical review of the safety of all the anti-VEGF agents currently used for treating myopic CNV including ranibizumab, aflibercept, conbercept, bevacizumab, and ziv-aflibercept. EXPERT OPINION Anti-VEGF therapy for myopic CNV with the currently available anti-VEGF drugs generally have favorable safety outcomes in the short-term. Nonetheless, ocular adverse events following anti-VEGF therapy for myopic CNV may develop and these include worsening or new development of myopic traction maculopathy, increased risk of retinal detachment, and progression of chorioretinal atrophy. Clinicians should be aware of these potential complications and evaluate them before and after anti-VEGF therapy.

Abstract
Aim: to identify clinical and laboratory biomarkers that determine the nature of the course of myopic choroidal neovascularization (mCNV) and the response to anti-VEGF therapy in women.Material and methods. A prospective non-randomized study was conducted in 52 patients (52 eyes) with active mCNV, treated with ranibizumab intravitreally, 0.5mg. After 12months, the suppression of CNV activity, the number of injections and the fellow eye inclusion in the pathological process were taken into account. There were 2 groups: with a favorable clinical course (n = 31, age – 33,0 ± 5,1 years, anterior-posterior axis (APA) 28,5 ± 0,3 mm) and an unfavorable clinical course (n = 21, age – 34,0 ± 4,1 years, APA – 29,01 ± 0,1 mm). Structural retinal changes, choroid thickness, retinal blood flow, and heart rate were evaluated using OCT and OCTA protocols (Optovue XR Avanti, USA). Studies were conducted before the start of therapy and then one time per month. The concentration of sex and pituitary hormones (ELISA analyzer “Immunohem-2100”), lipoprotein A, Apo B/Apo A (Accent 200 Cormay, Poland), coagulogram data (Helena C-2, UK), and the concentration of highly sensitive C-reactive protein in blood serum before the start of antiangiogenic therapy were studied once.Results. In the first group, 1.4 ± 0.7 ranibizumab injections were administered to suppress the CNV activity. In the opposite group – 3.5 ± 2.1 injections, in 73.7 % of cases, relapses were diagnosed, in 3 cases – primary CNV in the fellow eye. Clinical and laboratory biomarkers of the unfavorable clinical course of mCNV were identified: extreme choroidal thinning, highly organized membranes of a large area, dome-shaped deformation of the posterior pole, excess of the reference values of lipoprotein A, fibrinogen and highly sensitive C-reactive protein by two or more times, an imbalance of sex and pituitary hormones (excess of the reference values of prolactin, follicle stimulating hormone, cortisol, progesterone concentration decrease), a predominant change in the menstrual-ovarian cycle according to the type of amenorrhea and opsomenorrhea.Conclusion. Myopic CNV biomarkers in women allow predicting the response to anti-VEGF therapy, the formation of relapses and the inclusion of the fellow eye in the pathological process.

Abstract
Pathologic myopia is a major cause of visual impairment worldwide. Pathologic myopia is distinctly different from high myopia. High myopia is a high degree of myopic refractive error, whereas pathologic myopia is defined by a presence of typical complications in the fundus (posterior staphyloma or myopic maculopathy equal to or more serious than diffuse choroidal atrophy). Pathologic myopia often occurs in eyes with high myopia, however its complications especially posterior staphyloma can also occur in eyes without high myopia. Owing to a recent advance in ocular imaging, an objective and accurate diagnosis of pathologic myopia has become possible. Especially, optical coherence tomography has revealed novel lesions like dome-shaped macula and myopic traction maculopathy. Wide-field optical coherence tomography has succeeded in visualizing the entire extent of large staphylomas. The effectiveness of new therapies for complications have been shown, such as anti-VEGF therapies for myopic macular neovascularization and vitreoretinal surgery for myopic traction maculopathy. Myopia, especially childhood myopia, has been increasing rapidly in the world. In parallel with an increase in myopia, the prevalence of high myopia has also been increasing. However, it remains unclear whether or not pathologic myopia will increase in parallel with an increase of myopia itself. In addition, it has remained unclear whether genes responsible for pathologic myopia are the same as those for myopia in general, or whether pathologic myopia is genetically different from other myopia.

Abstract
A 15-year-old male was presented with blurred vision in his right eye for 2 weeks. The patient had a history of looking with the right eye for 5–6 s at a distance of 20 cm from green laser beam (class 3a, 5 mW, 532 nm). Dilated fundus examinations revealed a yellow lesion in the right eye, resulting in loss of foveal reflection at the fovea. Fundus fluorescein angiography (FFA) images and spectral-domain optical coherence tomography (OCT) scans were compatible with active classic choroidal neovascularization (CNV). A single dose of intravitreal aflibercept was performed to the right eye, and at the 1st month after the injection, the best-corrected visual acuity improved to 20/100 from 20/200. FFA showed staining of the scar with no leakage, and OCT revealed scar formation. At the follow-up visits, during 38-month follow-up, no CNV activity was observed. Intravitreal aflibercept may be an appropriate treatment option in cases with laser pointer injury-induced CNV.

Abstract
Purpose: To describe real world data in patients affected by myopic choroidal neovascularization (CNV) treated with anti-vascular endothelial growth factors (VEGFs) and to compare our results with previous studies and clinical trials. Methods: This retrospective monocentric cohort study analyzed 96 eyes of 96 myopic-CNV patients treated with an anti-VEGF pro-re-nata regimen over a 3-year-long follow up period. Aflibercept and Ranibizumab were considered as first-line agents whereas Bevacizumab was reserved on a compassionate basis in patients outside the criteria for treatment. All patients underwent a best-corrected visual acuity (BCVA) recording at each follow up visit. Results: Our data showed that all three molecules produced significant improvements in BCVA at year 1, with no significant differences between the three drugs. Moreover, during the second year of treatment, Ranibizumab and Bevacizumab showed a significant improvement in the visual function. However, at year 3 of treatment, the data available indicated the BCVA improvement was not significant with Ranibizumab and Bevacizumab. In addition, no significant difference in the average number of injections between the three groups was detected over the follow up period. No serious adverse events were recorded, but five minor adverse events documented. Conclusion: Our study correlates with previous studies showing significant BCVA gains with the use of these molecules. Similarly, all three molecules seem to provide a similar duration of effects as previous studies have shown, with a low ocular adverse event rate.

Abstract
PURPOSE To investigate changes in choriocapillaris vascular density (CCD) and choroidal thickness (CT) after femtosecond laser in situ keratomileusis (FS-LASIK) in myopic patients. METHODS Prospective and observational self-control study. We enrolled 41 myopic patients (41 right eyes), without other ophthalmic or systemic diseases who were eligible and about to FS-LASIK surgery. The CCD was measured in the central 1-mm-diameter circle region of the macular fovea (CCD1) and the 1- to 3-mm ring-like region of the fovea (CCD1-3). The CT was measured at the fovea and at distances of 0.5 and 2.5 mm for the following: nasal, temporal, superior, and inferior to the fovea. Both were measured by optical coherence tomography angiography (OCTA) preoperatively as the baseline and at 1 day, 1 week, 1 month, and 3 months postoperatively. RESULTS CCD1 and CCD1-3 were significantly lower postoperatively compared with baseline. When the trough was reached, CCD1 declined by 1.51%, and CCD1-3 declined by 1.00% at 1 day postoperatively. However, then they increased with time. CCD1 recovered to baseline at 1 month postoperatively, while CCD1-3 was still lower at the end of follow-up. In addition, the CT was significantly thicker postoperatively and recovered to the baseline at 3 months postoperatively. There was no obvious correlation between CCD, CT, and other parameters. CONCLUSIONS The CCD decreased while the CT increased following FS-LASIK in myopic patients. However, these changes may be a temporary stress response rather than real irreversible injury to the choroid.

Incomplete response to Anti-VEGF therapy in neovascular AMD: Exploring disease mechanisms and therapeutic opportunities. Prog Retin Eye Res 2020; 82:100906. [PMID: 33022379 PMCID: PMC10368393 DOI: 10.1016/j.preteyeres.2020.100906] [Citation(s) in RCA: 144] [Impact Index Per Article: 36.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2020] [Revised: 09/18/2020] [Accepted: 09/22/2020] [Indexed: 12/13/2022]
Abstract
Intravitreal anti-vascular endothelial growth factor (VEGF) drugs have revolutionized the treatment of neovascular age-related macular degeneration (NVAMD). However, many patients suffer from incomplete response to anti-VEGF therapy (IRT), which is defined as (1) persistent (plasma) fluid exudation; (2) unresolved or new hemorrhage; (3) progressive lesion fibrosis; and/or (4) suboptimal vision recovery. The first three of these collectively comprise the problem of persistent disease activity (PDA) in spite of anti-VEGF therapy. Meanwhile, the problem of suboptimal vision recovery (SVR) is defined as a failure to achieve excellent functional visual acuity of 20/40 or better in spite of sufficient anti-VEGF treatment. Thus, incomplete response to anti-VEGF therapy, and specifically PDA and SVR, represent significant clinical unmet needs. In this review, we will explore PDA and SVR in NVAMD, characterizing the clinical manifestations and exploring the pathobiology of each. We will demonstrate that PDA occurs most frequently in NVAMD patients who develop high-flow CNV lesions with arteriolarization, in contrast to patients with capillary CNV who are highly responsive to anti-VEGF therapy. We will review investigations of experimental CNV and demonstrate that both types of CNV can be modeled in mice. We will present and consider a provocative hypothesis: formation of arteriolar CNV occurs via a distinct pathobiology, termed neovascular remodeling (NVR), wherein blood-derived macrophages infiltrate the incipient CNV lesion, recruit bone marrow-derived mesenchymal precursor cells (MPCs) from the circulation, and activate MPCs to become vascular smooth muscle cells (VSMCs) and myofibroblasts, driving the development of high-flow CNV with arteriolarization and perivascular fibrosis. In considering SVR, we will discuss the concept that limited or poor vision in spite of anti-VEGF may not be caused simply by photoreceptor degeneration but instead may be associated with photoreceptor synaptic dysfunction in the neurosensory retina overlying CNV, triggered by infiltrating blood-derived macrophages and mediated by Müller cell activation Finally, for each of PDA and SVR, we will discuss current approaches to disease management and treatment and consider novel avenues for potential future therapies.

Abstract
AIMS To determine the prevalence and predictors of myopic macular degeneration (MMD) in a consortium of Asian studies. METHODS Individual-level data from 19 885 participants from four population-based studies, and 1379 highly myopic participants (defined as axial length (AL) >26.0 mm) from three clinic-based/school-based studies of the Asian Eye Epidemiology Consortium were pooled. MMD was graded from fundus photographs following the meta-analysis for pathologic myopia classification and defined as the presence of diffuse choroidal atrophy, patchy chorioretinal atrophy, macular atrophy, with or without 'plus' lesion (lacquer crack, choroidal neovascularisation or Fuchs' spot). Area under the curve (AUC) evaluation for predictors was performed for the population-based studies. RESULTS The prevalence of MMD was 0.4%, 0.5%, 1.5% and 5.2% among Asians in rural India, Beijing, Russia and Singapore, respectively. In the population-based studies, older age (per year; OR=1.13), female (OR=2.0), spherical equivalent (SE; per negative diopter; OR=1.7), longer AL (per mm; OR=3.1) and lower education (OR=1.9) were associated with MMD after multivariable adjustment (all p<0.001). Similarly, in the clinic-based/school-based studies, older age (OR=1.07; p<0.001), female (OR=2.1; p<0.001), longer AL (OR=2.1; p<0.001) and lower education (OR=1.7; p=0.005) were associated with MMD after multivariable adjustment. SE had the highest AUC of 0.92, followed by AL (AUC=0.87). The combination of SE, age, education and gender had a marginally higher AUC (0.94). CONCLUSION In this pooled analysis of multiple Asian studies, older age, female, lower education, greater myopia severity and longer AL were risk factors of MMD, and myopic SE was the strongest single predictor of MMD.

Rural-urban differences in myopia prevalence among myopes presenting to Bhutanese retinal clinical services: a 3-year national study. Graefes Arch Clin Exp Ophthalmol 2020; 259:613-621. [PMID: 32803328 DOI: 10.1007/s00417-020-04891-6] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2020] [Revised: 07/19/2020] [Accepted: 08/10/2020] [Indexed: 10/23/2022] Open
Abstract
PURPOSE To determine the prevalence and demographic characteristics of myopia among patients presenting to the national vitreo-retinal (VR) services in Bhutan. METHODS The records of the VR clinic at the apex national referral centre, providing the only VR services in the country, were reviewed to identify all new myopia patients over three years. Thus, we surveyed all referrals nationally. The patients were categorised into urban and rural females and males. We assessed myopia prevalence in each group by occupational and educational categories. We examined univariate prevalence data and a multivariate logistic regression (MLR) identified independent factors. RESULTS Of 2913 cases 1544 (53.0%) were males. Females presented earlier (mean ±SD): overall 45.7 ± 21.9 cf. 48.6 ± 21.6 years, p = 0.003, and among myopes 23.9 ± 13.5 cf. 27.6 ± 18.6 years, p = 0.032. Myopia constituted 92.1% of refractive error, an overall prevalence of 12.3%. Myopia was more common among females (p = 0.01) and urbanites (p = 0.02). Myopia prevalence was highest among urban females (20.9%), followed by urban males (11.9%), rural females (6.8%), and rural males (5.2%). Logistic regression revealed that the odds of having myopia were increased by being a student (4.96 ×) or professional (1.96 ×), and decreased by rural living (1.75 ×), all p ≤ 0.038. CONCLUSIONS This is the first study on myopia in Bhutan. As observed throughout East and Southeast Asia, the prevalence of myopia was higher in females and urbanites and positively associated with formal education. Given known risk factors, these prevalences may be driven by educational pressures and reduced time spent outdoors.

Abstract
High myopia and the subsequent degenerative changes of the retina, choroid, and sclera, known as myopic maculopathy (MM), are a serious visual problem in many Asian countries, and are beginning to be so in the south of Europe, especially in the Mediterranean. It is therefore necessary to carry out genetic and environmental studies to determine the possible causes of this disease. This study aims to verify if the genetic factors that have been most related to Asian populations are also associated in two Spanish cohorts. Eight SNPs from six genes (PAX6, SCO2, CCDC102B, BLID, chromosome 15q14, and COL8A1) along with demographic, ophthalmic and environmental factors were analysed in two cohorts from a total of 365 highly myopic subjects and 177 control subjects. The genetic analysis showed that COL8A1 SNP rs13095226 was associated with the development of choroidal neovascularization (CNV) and also seems to play an important role in the increase of axial length. The SNP rs634990 of chromosome 15q14 also showed a significant association with MM, although this was lost after the Bonferroni correction. Additional demographic and environmental factors, namely age, sex, smoking status, and pregnancy history, were also found to be associated with MM and CNV in this population.

Results of Ranibizumab Treatment of the Myopic Choroidal Neovascular Membrane according to the Axial Length of the Eye. J Ophthalmol 2020; 2020:3076596. [PMID: 32454987 PMCID: PMC7243022 DOI: 10.1155/2020/3076596] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2019] [Revised: 02/17/2020] [Accepted: 03/24/2020] [Indexed: 11/17/2022] Open
Abstract
Aim A retrospective evaluation of the results of treatment of myopic choroidal neovascularization (mCNV) with intravitreal injections of ranibizumab in a pro re nata (PRN) regimen in three groups of patients distributed according to axial length. Methods The paper presents a retrospective multicenter study carried out with the cooperation of several Departments of Ophthalmology in the Czech Republic. The study included 60 eyes of 60 patients suffering from mCNV, divided according to axial length into three groups. The first group consisted of 20 patients with an axial length of the eyes shorter than 28 mm (Group 1), the second group included 27 patients with axial lengths ranging from 28 mm to 29.81 mm (Group 2), and 13 patients had axial lengths longer than 30 mm (Group 3). All patients were first administered 3 initial intravitreal ranibizumab injections at monthly intervals (loading phase), and other injections were administered according to a PRN treatment regimen. Patients were evaluated before treatment and then at intervals of 3, 6, 9, and 12 months. The effect of ranibizumab treatment on the functional and morphological parameters of the affected eye was evaluated. Results The average baseline BCVA ± SD in Group 1 was 52.6 ± 12.5 letters of ETDRS optotypes, and at the end of the one-year follow-up, it was 63.3 ± 11.8 letters. The average baseline of CRT ± SD in this group was 377.4 ± 80.0 μm, and in the 12th month, it was 311.1 ± 63.7 μm. The average baseline BCVA ± SD in Group 2 was 50.2 ± 9.0 ETDRS letters, and at the end of the follow-up, it was 60 ± 12.4 letters. The average baseline of CRT ± SD in Group 2 was 391.2 ± 85.2 μm, and in the 12th month, it was 323.9 ± 91.2 μm. In Group 3, the average baseline of BCVA was 48.5 ± 14.5 ETDRS letters, and at the end of the one-year follow-up, it was 55.7 ± 16.1 letters. The average baseline CRT ± SD for Group 3 was 342.1 ± 94.9 μm, and after 12 months, it was 287.8 ± 88.4 μm. An improvement of BCVA by ≥15 letters of ETDRS optotypes was achieved by 3 patients of 20 (15%) in Group 1, by 5 patients of 27 (18.5%) in Group 2, and by 3 patients of 13 (23.1%) in Group 3. All these changes were statistically significant in comparison with the input values (p < 0.05). Conclusion Ranibizumab treatment in patients with mCNV in our study resulted in statistically significant improvement in BCVA and a decrease in CRT in all groups of patients. Our results from a routine clinical practice correspond with the results of large clinical studies; we confirm a particularly good effect of treatment in patients with axial lengths of the eye smaller than 28 mm.

Abstract
Bruch's membrane, an extracellular matrix located between the retinal pigment epithelium and the choroid, plays a vital role as structural and functional support to the retinal pigment epithelium. Dysfunction of Bruch's membrane in both age-related macular degeneration and other ocular diseases is caused mostly by extracellular matrix degeneration, deposit formation, and angiogenesis. Although these factors are dealt in greater detail with respect to the cells that are degenerated such as the retinal pigment epithelium and the endothelial cells, the pathology involving the Bruch's membrane is often underrated. Since in most of the macular degenerations early degenerative changes are also observed in the Bruch's membrane, addressing only the cellular component without the underlying membrane will not yield an ideal clinical benefit. This review aims to discuss the factors and the mechanisms affecting the integrity of the Bruch's membrane, which would aid in developing an effective therapy for these pathologies.

Abstract
PURPOSE This review discusses the etiology and pathogenesis of myopia, prevention of disease progression and worsening axial elongation, and emerging myopia treatment modalities. INTRODUCTION Pediatric myopia is a public health concern that impacts young children worldwide and is associated with numerous future ocular diseases such as cataract, glaucoma, retinal detachment and other chorioretinal abnormalities. While the exact mechanism of myopia of the human eye remains obscure, several studies have reported on the role of environmental and genetic factors in the disease development. METHODS A review of literature was conducted. PubMed and Medline were searched for combinations and derivatives of the keywords including, but not limited to, "pediatric myopia", "axial elongation", "scleral remodeling" or "atropine." The PubMed and Medline database search were performed for randomized control trials, systematic reviews and meta-analyses using the same keyword combinations. RESULTS Studies have reported that detection of genetic correlations and modification of environmental influences may have a significant impact in myopia progression, axial elongation and future myopic ocular complications. The conventional pharmacotherapy of pediatric myopia addresses the improvement in visual acuity and prevention of amblyopia but does not affect axial elongation or myopia progression. Several studies have published varying treatments, including optical, pharmacological and surgical management, which show great promise for a more precise control of myopia and preservation of ocular health. DISCUSSION Understanding the role of factors influencing the onset and progression of pediatric myopia will facilitate the development of successful treatments, reduction of disease burden, arrest of progression and improvement in future of the management of myopia.

Long-term outcomes of the intravitreal injection of ranibizumab for the treatment of choroidal neovascularization secondary to pathologic myopia. Int Ophthalmol 2019; 40:833-839. [PMID: 31788714 DOI: 10.1007/s10792-019-01247-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2019] [Accepted: 11/23/2019] [Indexed: 10/25/2022]
Abstract
PURPOSE To analyze the long-term outcomes and safety of intravitreal ranibizumab injections in myopic choroidal neovascularization (CNV). METHODS A retrospective non-randomized analysis of consecutive cases included 17 eyes from 17 patients with subfoveal myopic CNV, treated with intravitreal ranibizumab with at least 30-month follow-up. The patients received three injections monthly, followed by pro re nata regimen. Best-corrected visual acuity (BCVA) measurement, optical coherence tomography and fluorescein angiography were carried out at the baseline and at monthly intervals thereafter. RESULTS Mean follow-up period was 51 months (range 30-98 months). In 12 patients (70.6%), BCVA improved by at least 1 Snellen line, with at least 3-line improvement observed in the case of 8 eyes (47%). Mean central foveal thickness (CFT) decreased from 384.65 ± 103.3 µm at the baseline to 264 ± 86.2 µm at the last follow-up examination (p < 0.001). The final OCT examination revealed 59% (10/17) eyes with CNV-related macular atrophy. Mean number of injections over the follow-up period was 4.82 ± 2.04 per person. Nine patients (53%) required re-injection of the anti-VEGF agent; the mean number of re-injections in this group was 3.44 ± 1.34 per person (range 2-6). No significant adverse events were recorded during the study period. CONCLUSIONS Intravitreal ranibizumab is an effective and safe treatment for CNV secondary to pathologic myopia, contributing to long-term vision improvement and CFT reduction.

Abstract
Purpose To analyze the frequency and phenotypic variation of AMD in subjects with high myopia (HM), and to describe the clinical course and response to treatment of neovascularization (NV). Methods Patients with HM were identified at five retina tertiary referral centers. Inclusion criteria were myopic patients aged 55 years or more with axial lengths equal or greater than 25.5 mm. Results A total of 874 eyes from 442 HM subjects older than 55 years were identified and 104 eyes of 54 patients (72 ± 11 years) were included in the study and followed up for 23.5 ± 19.5 months. The estimated AMD frequency in HM subjects over 55 years was 11.9% (95% confidence interval; 9.8%-14.0%). A total of 34 of 104 eyes were diagnosed with drusen, 22 with reticular pseudodrusen (RPD), 28 with both drusen and RPD, and 20 with geographic atrophy. Neovascularization was detected in 52 eyes (50%), and type 1 was the most frequent form (39 eyes, 75%). Overall, NV was treated with 4.6 ± 2.6 anti-VEGF injections. Eyes with treatment-naïve NV at baseline (n = 34) required 3.8 ± 1.5 anti-VEGF injections during the first year of treatment. This exceeded the injection number in the purely myopic population (1.8 to 3.6 injections for the first year). Conclusions This study provides evidence to suggest that older patients with HM are at a significant risk of the dry and neovascular forms of AMD. NV in eyes with HM and AMD required more injections in the first year compared to NV in HM eyes without AMD.

LONG-TERM OUTCOMES OF RANIBIZUMAB TREATMENT OF MYOPIC CHOROIDAL NEOVASCULARIZATION IN EAST-ASIAN PATIENTS FROM THE RADIANCE STUDY. Retina 2019; 38:2228-2238. [PMID: 28961671 PMCID: PMC6221407 DOI: 10.1097/iae.0000000000001858] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/25/2022]
Abstract
A retrospective cohort study of East-Asian patients previously treated with ranibizumab for myopic choroidal neovascularization in the RADIANCE trial. Clinical charts were reviewed to assess long-term efficacy and safety. Visual acuity was sustained for additional 36 months after trial completion with few patients requiring additional treatment and no new safety concerns observed. Purpose: To evaluate long-term efficacy and safety of ranibizumab for treatment of myopic choroidal neovascularization (mCNV) in clinical practice. Methods: Noninterventional, retrospective cohort study of East-Asian patients previously treated with ranibizumab during the RADIANCE trial. Forty-one patients who completed the RADIANCE trial were followed-up for up to 48 months (post-RADIANCE observation period). Outcome measures were best-corrected visual acuity changes from baseline (assessed at RADIANCE trial initiation), mCNV recurrences, and ocular adverse events. Results: Mean visual gain from baseline best-corrected visual acuity (56.5 ± 12.1 letters) (20/80) was significant at 12 months (+14.3 ± 11.4 letters, n = 40, P < 0.0001), 24 months (+10.4 ± 22.3 letters, n = 31, P = 0.0143), 30 months (+11.0 ± 22.4 letters, n = 29, P = 0.0134), 42 months (+12.9 ± 20.9 letters, n = 25, P = 0.0051), and 48 months (+16.3 ± 18.7, n = 16, P = 0.0034). Of the 16 patients who completed 48 months of follow-up, 63% gained ≥10 letters and 13% lost ≥10 letters. Over the post-RADIANCE observation period, 83% of patients required no further treatment for mCNV, 10% experienced mCNV recurrences, and 12% experienced a nonserious ocular adverse event. Patients who required additional treatment for mCNV received a mean of 5.0 (SD 5.9, range 1.0–18.0) ranibizumab injections. Conclusion: Best-corrected visual acuity gained at the end of the RADIANCE trial was sustained over additional 36 months of follow-up. Few patients required further treatment and no new safety concerns were observed.

Abstract
PURPOSE To determine the influence of baseline myopic macular degeneration (MMD) severity on outcomes with intravitreal aflibercept (IVT-AFL) in patients with myopic choroidal neovascularization (CNV). METHODS MYRROR was a randomized, double-masked study in patients with myopic CNV treated with IVT-AFL/sham over 48 weeks. At baseline/week 48, images were retrospectively graded for MMD. RESULTS At baseline, 115 eyes had a valid MMD grading result; at week 48, grading results were available for 99 eyes [IVT-AFL (n = 78)/sham (n = 21)]. Severity of baseline MMD was distributed as follows: category 1: 19/115 (17%); category 2: 67/115 (58%); category 3: 22/115 (19%); category 4: 7/115 (6%). Higher MMD category was associated with older age (nominal p = 0.007) and longer axial length (nominal p = 0.025). At week 48, patients in the mild and severe groups had visual acuity gains of +13.5 and +12.4 letters, respectively. Baseline MMD severity did not significantly affect visual/anatomical outcomes or number of treatments. Visual Functioning Questionnaire-25 scores improved more in mild (+5.6) versus severe (+0.4) MMD (nominal p = 0.03). There were no new safety events. CONCLUSIONS Visual acuity gains, morphological outcomes and dosing frequency were not affected by baseline MMD severity in patients treated with IVT-AFL. A benefit with IVT-AFL treatment was observed for all baseline MMD stages included in this study.

Exp Ther Med 2019; 18:589-595. [PMID: 31258694 PMCID: PMC6566017 DOI: 10.3892/etm.2019.7610] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2018] [Accepted: 02/21/2019] [Indexed: 11/18/2022] Open
Abstract
The aim of the present study was to investigate whether internal limiting membrane (ILM) peeling in patients with myopic foveoschisis (MF) treated with 23-gauge (23G) vitrectomy improved the anatomical and visual outcomes. In this retrospective cohort study, from March 2014 to August 2017 at the Department of Ophthalmology, The Second Affiliated Hospital of Nanchang University (Nanchang, China), 60 patients (60 eyes) with MF underwent 23G vitrectomy. The patients were grouped according to whether they underwent brilliant blue-assisted ILM peeling (peeling group) or not (non-peeling group). Best-corrected visual acuity (BCVA) and central macular thickness (CMT) on optical coherence tomography were measured. There were 30 eyes in each group and the baseline characteristics were similar (all P>0.05). BCVA improved in 24 eyes (80%) in the peeling group and 25 eyes (83.3%) in the non-peeling group (P=0.922). Preoperative CMT was not significantly different between the peeling and non-peeling group (458±62.2 vs. 460±61.1 µm, respectively, P=0.229). However, postoperative CMT was significantly different between the peeling and non-peeling group (269.3±67.7 vs. 294.4±60.5 µm, respectively; P=0.015). In the peeling group, MF was completely resolved in all 30 eyes, but only in 26 eyes in the non-peeling group (P=0.038). Postoperative Amsler testing was positive in five eyes in the peeling group and 13 eyes in the non-peeling group (P=0.024). Complications were similar in both groups; postoperatively, there were one and two cases of iatrogenic peripheral retinal break, three and two cases of macular hole, and one and one case of retinal detachment in the peeling and non-peeling groups, respectively.23G vitrectomy combined with brilliant blue-assisted ILM peeling resulted in better visual and anatomical effects compared with 23G vitrectomy alone in patients with MF.

Novel Predictors of Visual Outcome in Anti-VEGF Therapy for Myopic Choroidal Neovascularization Derived Using OCT Angiography. Ophthalmol Retina 2019; 2:1118-1124. [PMID: 31047549 DOI: 10.1016/j.oret.2018.04.011] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2018] [Revised: 04/11/2018] [Accepted: 04/16/2018] [Indexed: 12/30/2022]
Abstract
PURPOSE To explore novel prognostic factors associated with visual function and number of anti-vascular endothelial growth factor (VEGF) treatments in eyes with active myopic choroidal neovascularization (mCNV) using OCT angiography (OCTA). DESIGN Prospective case series. PARTICIPANTS Twenty-eight treatment-naïve eyes with active mCNV from 27 consecutive patients (mean age, 64.4 ± 11.1 years). METHODS All eyes received through injection a single loading dose of intravitreal aflibercept (IVA), followed by additional IVA on a pro re nata (PRN) basis during the subsequent 12 months. At baseline, OCTA images of a 3 × 3-mm macular cube were acquired using an OCTA scanner. On binarized and skeletonized OCTA images of the outer retinal layer, OCTA-derived baseline parameters of mCNV-including lesion size, vessel density, vessel length density (VLD), vessel diameter index, and fractal dimension (FD)-were measured and evaluated for correlation with 12-month best-corrected visual acuity (BCVA) and number of additional injections. MAIN OUTCOME MEASURES The primary and secondary outcomes were BCVA 12 months after initial treatment and number of additional injections, respectively. RESULTS There was no significant difference between baseline and 12-month BCVA (0.37 ± 0.30 and 0.30 ± 0.35 logarithm of the minimal angle of resolution, respectively; P = 0.23). The number of additional injections was 0.93 ± 1.02 (mean ± standard deviation). Baseline VLD, FD, and BCVA were correlated with 12-month BCVA (P = 0.02, r = 0.46; P = 0.02, r = 0.46; and P = 0.02, r = 0.45, respectively), and VLD also was correlated with the number of additional injections (P = 0.03, r = 0.42). CONCLUSIONS Exuberant mCNV, which is characterized by high VLD and FD derived using OCTA, is a predictor of poor visual outcomes after a single IVA injection followed by a PRN regimen. Only baseline VLD was correlated with the number of additional IVA injections, which indicates that this parameter could help to determine the optimal anti-VEGF treatment regimen for individual eyes with mCNV.

Abstract
Purpose: To investigate the relation between high axial myopia and neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) values.Methods: Seventy-nine cases were enrolled, 50 myopic and 29 emmetropic. All participants were assigned into three groups: Group I (high myopia with no retinal involvement), Group II (high myopia with retinal involvement) and Group III (control). NLR and PLR values calculated from blood tests were compared among the groups.Results: Mean NLR levels were 2.23 ± 0.78 in Group I, 2.36 ± 1.06 in Group II, and 1.57 ± 0.33 in Group III. Mean PLR levels were 114.62 ± 23.21 in Group I, 145.16 ± 52.36 in Group II, and 91.42 ± 18.73 in Group III. NLR and PLR values in the high myopia groups were significantly higher than in the control group.Conclusion: NLR and PLR values in cases with high axial myopia were higher than in the emmetropic group. Higher inflammation in the degenerative myopic group in particular may be related to pathological chorioretinal changes.
