Abstract
We identified characteristics of patients with subretinal fluid (SRF) in macular edema (ME) secondary to branch retinal vein occlusion (BRVO) and determined their clinical outcomes after anti-vascular endothelial growth factor (VEGF) treatment. Fifty-seven eyes of BRVO patients with ME were divided into two groups according to the presence or absence of SRF at diagnosis. We compared the aqueous profiles, ocular and systemic characteristics at baseline, and the clinical outcomes. The SRF group had significantly greater central subfield thickness (CST) values and poorer best-corrected visual acuity (BCVA) at baseline compared to the non-SRF group. The former group had significantly higher aqueous levels of interleukin-8, VEGF, and placental growth factor. CST reduction and BCVA improvement during treatment were significantly greater in the SRF group than in the non-SRF group. Consequently, CST values were significantly lower in the SRF group than in the non-SRF group at 12 months, when BCVA did not differ significantly between the two groups. The SRF group required more frequent anti-VEGF treatment over 12 months and exhibited a higher rate of macular atrophy. Based on the aqueous profiles and the number of treatments required, the presence of SRF in BRVO patients appears to be associated with higher disease activity.

Abstract
In this longitudinal retrospective image analysis, conducted on patients diagnosed with dry age-related macular degeneration (AMD) and 5 years of follow-up imaging data, the study aimed to investigate the relationship between ellipsoid zone (EZ) integrity on spectral domain optical coherence tomography (SD-OCT) and visual acuity (VA). Using a machine learning-enabled feature extraction tool, quantitative EZ parameters were derived from SD-OCT images. The analysis revealed significant correlations between EZ integrity metrics and VA. Eyes with excellent VA (≥20/25 Snellen) exhibited higher EZ integrity, including less EZ attenuation, thicker ellipsoid zone-retinal pigment epithelium (EZ-RPE) thickness, and higher EZ intensity, in contrast to eyes with worse VA (≤20/40 Snellen). Additionally, eyes with geographic atrophy (GA) in the foveal region displayed compromised EZ integrity compared to those without GA. Notably, baseline EZ integrity metrics were predictive of future VA loss. These findings suggest that quantitative SD-OCT measurements of EZ integrity could potentially detect early changes in dry AMD and serve as valuable indicators for predicting future functional outcomes. Furthermore, these measurements hold promise for use in clinical trial screenings, offering insights into the progression of the disease and its impact on visual acuity. This study underscores the importance of EZ integrity assessment in understanding and managing dry AMD.

Month 60 Imaging Findings and Relationship to Treatment Outcomes Following Anti-VEGF Therapy for Macular Edema Due to Central or Hemi-Retinal Vein Occlusion. Am J Ophthalmol 2024; 260:147-159. [PMID: 38061584 DOI: 10.1016/j.ajo.2023.11.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2022] [Revised: 11/22/2023] [Accepted: 11/27/2023] [Indexed: 01/21/2024]
Abstract
PURPOSE To evaluate imaging findings from SCORE2 participants through 60 months, to describe the degree of resolution or progression of these variables, and to correlate changes in these imaging findings to treatment outcomes such as visual acuity and the number of treatments administered. METHODS SCORE2 participants were followed for up to 60 months. Visual acuity, injection frequency and imaging tests color fundus photography (CFP), optical coherence tomography (OCT), and ultra-widefield fluorescein angiography [UWFA]) were performed throughout this period. RESULTS Less than 6% of eyes had subretinal fluid at month 60. Disorganization of the retinal inner layers (DRIL) was the most likely finding to persist, present in 96% of eyes at baseline and unchanged at 95% at month 60. For UWFA, at baseline, there was a mean of 5.0% non-perfusion area (95% CI: 3.3%-6.8%) in the NETWORC grid with little change to month 60. For the Early Treatment Diabetic Retinopathy Study (ETDRS) grid, at baseline, there was a mean of 2.3% non-perfusion area (95% CI: 0.7%-3.9%) with little change to month 60. There was no correlation between any of the imaging variables at baseline and change in visual acuity to month 60 or in the number of injections following the variable treatment timeframe (month 12 to month 60). CONCLUSIONS These analyses provide an anatomic explanation for persistent functional deficits many years following initial treatment. Clinical practice patterns should consider evaluation with these imaging tests to help explain persistent functional deficits in many eyes. Additionally, these 8 baseline imaging variables generally should not be relied on to predict visual acuity or intensity of treatment.

Choroidal hypertransmission width on optical coherence tomography: a prognostic biomarker in idiopathic macular hole surgery. Graefes Arch Clin Exp Ophthalmol 2024:10.1007/s00417-024-06427-8. [PMID: 38530449 DOI: 10.1007/s00417-024-06427-8] [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: 11/01/2023] [Revised: 01/16/2024] [Accepted: 02/14/2024] [Indexed: 03/28/2024] Open
Abstract
PURPOSE To test the hypothesis that optical coherence tomography (OCT) choroidal hypertransmission width (CHW) is a prognostic biomarker in idiopathic macular hole (MH) surgery METHODS: Retrospective cohort study of consecutive patients undergoing successful pars plana vitrectomy for idiopathic MH. We collected demographic, clinical, and OCT variables at the preoperative and last available visits. Two investigators assessed the following OCT parameters: MH minimum diameter, base diameter, CHW, ellipsoid zone, and external limiting membrane status (absent vs. present). Delta CHW was calculated as the difference between CHW and MH minimum diameter. Linear models were used to investigate factors associated with postoperative best-corrected visual acuity (BCVA) and BCVA change. RESULTS Thirty-six eyes (36 patients) with a median (interquartile range (IQR)) follow-up of 9 (8-11) months were included. The median BCVA (IQR) improved from 0.75 (1-0.6) logMAR preoperatively to 0.2 (0.6-0.1) logMAR at the last visit (p < 0.001). Preoperative MH minimum diameter (for a 10-μm increase, estimate (standard error (SE)): 0.009 (0.003) logMAR, p = 0.003), base diameter (for a 10-μm increase, 0.003 (0.001) logMAR, p = 0.032), CHW (for a 10-μm increase, 0.008 (0.002) logMAR, p < 0.001), and delta CHW (for a 10-μm increase, 0.013 (0.005) logMAR, p = 0.009) were significantly associated with postoperative BCVA. The proportion of variance explained was the highest for MH CHW (R2 0.35), followed by minimum MH diameter (R2 0.24), delta CHW (R2 0.19), and MH base diameter (R2 0.14). None of the study variables was associated with delta BCVA. CONCLUSION Preoperative CHW is associated with postoperative visual acuity in patients undergoing successful idiopathic MH surgery and may be a useful OCT prognostic biomarker.

Abstract
PURPOSE To analyze the clinical features of refractory cystoid macular edema related to retinal vein occlusion associated with the response to three consecutive loading doses of anti-vascular endothelial growth factor. METHODS A retrospective chart review was performed on retinal vein occlusion patients treated by three anti-vascular endothelial growth factor injections. They were divided into a group according to resolution of macular edema in optical coherence tomography (Group 1) and with persistent macular edema (Group 2). We analyzed qualitative and quantitative morphologic features of optical coherence tomography. RESULTS We enrolled a total of 120 eyes from 120 patients (Group 1: n = 54, Group 2: n = 66). The baseline choroidal thickness differed significantly between groups 1 and 2 (290.70 ± 19.58 μm and 311.06 ± 17.87 μm P < 0.001). The presence of Hyperreflective foci (16.70% vs. 36.40% P < 0.001), Disorganization of the retinal inner layers (14.80% vs. 87.90%) and external limiting membrane disruption (16.60% vs. 39.3% P < 0.001) differed significantly. Logistic regression analysis showed that the initial central macular thickness (B = 0.012; P = 0.006), baseline choroidal thickness (B = 0.232; P = 0.016) and presence of hyperreflective foci (B = 1.050; P = 0.019), disorganization of the retinal inner layers (B = 1.132; P = 0.001) and external limiting membrane disruption (B = 1.575; P = 0.012) significantly affected the anti-vascular endothelial growth factor treatment response. CONCLUSION A thicker sub-fovea choroid and the presence of hyperreflective foci, disruption of the external limiting membrane and disorganization of the retinal inner layers associated with a poorer response to three loading anti-vascular endothelial growth factor injections in macular edema associated retinal vein occlusion.

Abstract
PURPOSE To study visual function, retinal layer thickness changes, and tangential displacement after pars plana vitrectomy for epiretinal membrane. METHODS Retrospective series of patients undergoing pars plana vitrectomy for epiretinal membrane, with 6-month follow-up including best-corrected visual acuity, optical coherence tomography, M-charts, epiretinal membrane grading, and infrared fundus photograph at time 0 (T0, preop) at months 1 (T1), 3 (T3), and 6 (T6) postop (±1 week). Retinal layer thickness and tangential ( en face ) retinal displacement between successive times for the entire retinal surface and the central horizontal and vertical meridian were also measured. En face displacement was calculated as optical flow of consecutive images. RESULTS Average best-corrected visual acuity improved from 0.28 ± 0.08 logarithm of Minimum Angle of Resolution at T0 to 0.16 ± 0.25 at T6 ( P = 0.05), best-corrected visual acuity improvement correlated with best corrected visual acuity (BCVA) at T0 ( P < 0.001). Vertical metamorphopsia decreased from 1.33° ± 0.70° at T0 to 0.82° ± 0.69° at T6 ( P < 0.05). Foveal thickness reduced from 453 ± 53 µ m at T0 to 359 ± 31 µ m at T6 ( P < 0.05) and reduction correlated with best-corrected visual acuity improvement ( P < 0.05). Foveal layers decreased ( P < 0.05) in all cases. The mean en face deformation was 155.82 ± 50.17 µ m and mostly occurred in the first month: T0-T1 displacement was 83.59 ± 30.28 µ m, T1-T3 was 36.28 ± 14.45 µ m, while T3-T6 was 39.11 ± 22.79 µ m ( P < 0.001) on average. Perifoveal and parafoveal deformation correlated with optical coherence tomography foveal thickness reduction at all time intervals (1, 3, and 6 months: P < 0.01). CONCLUSION Epiretinal membrane peeling affects all retinal layer thickness and results in new force balance across the entire retina and tangential displacement. Both en face and in-depth changes correlate with visual function.

Abstract
PURPOSE To investigate the associations between visual acuity (VA) and structural optical coherence tomography (OCT) features in retinal vein occlusion (RVO) eyes after cystoid macular oedema (CMO) regression and to assess whether inner retinal thinning is progressive. METHODS Retrospective observational study of RVO eyes with regressed CMO for at least 6 months. OCT scans at CMO regression were analysed, and features were correlated with VA at that visit. The inner retinal thickness was longitudinally compared between RVO and unaffected fellow eyes (controls) with linear mixed models. The rate of inner retinal thinning was obtained as the interaction term between disease status and time. Associations between inner retinal thinning and clinical characteristics were explored. RESULTS Thirty-six RVO eyes were followed for 34.2 ± 21.1 months after CMO regression. The presence of ellipsoid zone disruption (regression estimate[standard error(SE)] = 0.16[0.04] LogMAR vs. intact, p < 0.001) and lower inner retinal thickness (regression estimate[SE] = -0.25[0.12] LogMAR for 100-μm increase, p = 0.01) were associated with worse VA. The inner retinal thickness decreased faster in RVO than controls (rate of retinal thinning -0.27 ± 0.09 μm/month vs. -0.08 ± 0.11 μm/month, p = 0.01). Macular ischaemia was associated with a faster rate of retinal thinning (interaction term macular ischaemia*follow-up time, p = 0.04). CONCLUSION Inner retinal and photoreceptors' layers integrity are associated with better visual acuity once CMO resolves. RVO eyes undergo progressive inner retinal thinning after CMO regression, faster in eyes with macular ischaemia.

Abstract
PURPOSE To determine whether macular infarction measured as hyper-reflectivity of the middle and inner retinal layers predicts long-term visual acuity outcomes in participants with central retinal vein occlusion (CRVO) or hemi-retinal vein occlusion (HRVO). DESIGN Clinical cohort study using post hoc secondary analysis of phase 3 clinical trial data. METHODS This post hoc secondary analysis of the phase 3 Study of COmparative Treatments for REtinal Vein Occlusions 2 (SCORE2) clinical trial included 310 of the 362 participants with macular edema secondary to CRVO/HRVO who were randomized to injections of aflibercept or bevacizumab. Month 01 (M01) optical coherence tomography (OCT) images were analyzed using the following grading scheme: no infarction (grade 0), only middle retinal infarction (grade 1), diffuse middle and patchy inner retinal infarction (grade 2), and diffuse middle and inner retinal infarction (grade 3). Visual acuity letter score (VALS), central subfield thickness (CST), and number of anti-vascular endothelial growth factor (anti-VEGF) injections were correlated with the infarction severity grade at month 01. RESULTS More severe macular infarction, with both middle and inner retinal layer hyper-reflectivity (ie, grades 2 and 3), was associated with worse M00 VALS and was predictive of VALS at M01 to M60 (P < .001). More severe infarction was associated with greater CST at presentation; however, after the first anti-VEGF injection, CST decreased and was similar across all grades at all time points (P > .05) with similar number of injections. CONCLUSIONS Participants with more severe macular infarction at M01, as graded with OCT, exhibited worse visual outcomes despite significantly improved macular edema from month 6 to 5 years. This suggests that macular infarction may drive visual acuity after retinal fluid is treated with anti-VEGF.

Abstract
AIMS This study aims to compare the effectiveness of treatment between anti-vascular endothelial growth factor (anti-VEGF) agents in diabetic macular edema (DME) patients with disorganization of retinal inner layers (DRIL). Epiretinal membrane, serous macular detachment, ellipsoid zone (EZ) disorder, external limiting membrane (ELM) disorder, and hyperreflective foci were also examined. METHODS Patients treated for DME and also had DRIL were included in the study. The study design was retrospective and cross-sectional. The complete ophthalmologic records and imaging were scanned at the beginning, 3rd-month, 6th-month, and 12th-month follow-up, and the treatments administered were recorded. Anti-VEGF agents administered to the patients were examined in three groups: bevacizumab, ranibizumab, and aflibercept. RESULT A total of 141 eyes of 100 patients were included in our study. One hundred and fifteen eyes (81.6%) had a BCVA of 0, 5, or less at the beginning. There was no statistically significant difference between the three groups regarding initial BCVA and CMT and the change in BCVA and CMT at the beginning and the 12th month (p > 0.05). There was a negative correlation between EZ and ELM disorders in patients and the change in BCVA at 12 months (r: 0.45 p < 0.001, r: 0.32 p < 0.001, respectively). The number of injections over five was positively correlated with the change in CMT but not with BCVA (r: - 2.35 p = 0.005 and r: 0.147 p = 0.082, respectively). CONCLUSIONS No statistically significant difference was found between anti-VEGF agents when treating DME patients with DRIL. In addition, we have shown that anatomically better results were obtained in those who had five or more injections, although not in terms of BCVA.

Predictors of treatment outcomes following treat-and-extend regimen with aflibercept for branch retinal vein occlusion: post-hoc analysis of the PLATON trial. Sci Rep 2023; 13:11730. [PMID: 37474669 PMCID: PMC10359445 DOI: 10.1038/s41598-023-38955-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Accepted: 07/18/2023] [Indexed: 07/22/2023] Open
Abstract
We investigated predictors of visual outcomes and injection interval in macular edema (ME) secondary to branch retinal vein occlusion (BRVO) treated with a treat-and-extend (TAE) regimen. All 48 patients in a multicenter study were followed for 52 weeks and received three monthly intravitreal aflibercept injections before the TAE regimen, with treatment intervals adjusted by 4 weeks, up to a maximum of 16 weeks. Various laboratory biomarkers and optical coherence tomography parameters were evaluated. Patients were classified into the extension failure group if they had ≥ 1 treatment interval decreased due to an increase in the central macular thickness compared to the previous visit and 18 patients were assigned to this group. In multivariate logistic analyses, presence of microaneurysms and prominent middle limiting membrane (p-MLM) sign, increased initial external limiting membrane (ELM) disruption, and higher total cholesterol were correlated with inhibiting a sustained extension in the injection interval (P = 0.015, P = 0.032, P = 0.037, P = 0.009, respectively). Therefore, in the patients with ME secondary to BRVO with these risk factors, early consideration of frequent injection may improve treatment outcome.

Abstract
Purpose To assess the association of a novel spectral domain optical coherence tomography biomarker with 6-month visual acuity in in the Study of COmparative Treatments for REtinal Vein Occlusion 2. Methods Spectral domain optical coherence tomography volume scans were evaluated for inner retinal hyperreflectivity, quantified by optical intensity ratio (OIR) and OIR variation. Baseline visual acuity letter score (VALS), baseline OCT biomarkers, and month 1 OIR were correlated with VALS at month 6. Regression trees, a machine learning technique yielding readily interpretable models, were used to assess for variable interaction. Results Only baseline VALS correlated positively with month 6 VALS in multivariate regression. Regression trees detected a novel functional and anatomical interaction in a subgroup. Among patients with a baseline VALS worse than 43, those with an OIR variation at month 1 of more than 0.09 had a mean of 13 fewer letters of vision at 6 months compared with patients with an OIR variation of 0.09 or less. Conclusions Baseline VALS was the strongest predictor of month 6 VALS. Regression tree analysis detected an interaction effect, in which higher OIR variation at month 1 predicted worse 6-month VALS in patients with low VALS at baseline. OIR variation may serve as a predictor for poor visual outcome despite treatment of macular edema secondary to retinal vein occlusion in patients with poor vision at baseline. Translational Relevance Pixel heterogeneity in three-dimensional OCT data may serve as measure of disruption of the retinal laminations, and this factor may carry visually prognostic value.

Abstract
BACKGROUND To compare the surgical status in idiopathic epiretinal membrane (IERM) patients with or without disorganization of retinal inner layers (DRIL) and to correlate with optical coherence tomography angiography (OCTA) and clinical data. METHODS In 74 eyes from 74 patients with IERM treated by surgery with 12-month follow-up. According to the superficial hemorrhage, the patients were divided into group A (no macular bleeding), group B (macular parafoveal bleeding) and group C (macular foveal bleeding). Optical coherence tomography (OCT) were evaluated for presence of DRIL,central retina thickness and integrity of the inner/outer segment layer recorded at baseline and at 1, 3, 6, and 12 months postoperatively and best-corrected visual acuity (BCVA) was recorded simultaneously. OCTA was conducted at 12 months postoperatively. Main outcome measures is correlation between DRIL and superficial hemorrhage in membrane peeling,and BCVA and OCTA outcomes postoperatively. RESULTS The rate of DRIL and BCVA had statistically significant differences between the three groups at the time points(baseline and 1, 3, 6, and 12 months after surgery), respectively (P < 0.001 for all). FD-300 value (P = 0.001)and DCP in all parafoveal regions (superior: P = 0.001; inferior: P = 0.002;Nasal: P = 0.014;Tempo: P = 0.004) in eyes with DRIL were lower than those without DRIL.There was a linear regression relationship between FD-300 and postoperative BCVA (P = 0.011). CONCLUSION IERM Patients with DRIL have more intraoperative adverse events and limited benefits from surgery which should be considered in the decision whether to perform mebrane peeling.OCT-A provides more detailed vascular information that extends our understanding of persistent DRIL.

Abstract
Quantifying the smoothness of different layers of the retina can potentially be an important and practical biomarker in various pathologic conditions like diabetic retinopathy. The purpose of this study is to develop an automated machine learning algorithm which uses support vector regression method with wavelet kernel and automatically segments two hyperreflective retinal layers (inner plexiform layer (IPL) and outer plexiform layer (OPL)) in 50 optical coherence tomography (OCT) slabs and calculates the smoothness index (SI). The Bland-Altman plots, mean absolute error, root mean square error and signed error calculations revealed a modest discrepancy between the manual approach, used as the ground truth, and the corresponding automated segmentation of IPL/ OPL, as well as SI measurements in OCT slabs. It was concluded that the constructed algorithm may be employed as a reliable, rapid and convenient approach for segmenting IPL/OPL and calculating SI in the appropriate layers.

Abstract
SYNOPSIS/PRECIS We investigated the relationship between contrast sensitivity (CS) and vision-related quality of life (VR-QOL) in patients with central retinal vein occlusion following ranibizumab intravitreal injection; CS showed a stronger association with VR-QOL than visual acuity. BACKGROUND/AIMS To investigate the relationship between CS, VR-QOL and optical coherence tomography (OCT) findings in patients with cystoid macular oedema secondary to central retinal vein occlusion (CRVO-CMO) following intravitreal injection of ranibizumab. METHODS This was a multicentre, open-label, single-arm, prospective study. The study included 23 patients with CRVO-CMO who were followed up for 12 months after treatment. The best-corrected visual acuity (BCVA), letter contrast sensitivity (LCS) and OCT images were obtained every month. For VR-QOL assessment, the 25-item National Eye Institute Visual Function Questionnaire (VFQ-25) was administered to the patients before treatment and at 3, 6 and 12 months following treatment. RESULTS The LCS and VFQ-25 composite score improved significantly from baseline to 12 months following treatment. The multiple regression analysis revealed that the LCS of the affected eye and BCVA of the fellow eye were related to the VFQ-25 composite score following treatment. The LCS improvement showed a significant correlation with the improvement in the VFQ-25 composite score, whereas the BCVA improvement was not correlated with the improvement in the VFQ-25 composite score. Stepwise multiple regression analyses revealed that, at the time of macular oedema resolution, the distance between the external limiting membrane and retinal pigment epithelium (ELM-RPE) and average ganglion cell-inner plexiform layer (GCIPL) thickness were associated with LCS. CONCLUSION CS had a stronger association with VR-QOL than with BCVA in patients with CRVO-CMO. With the resolution of macular oedema, CS was associated with ELM-RPE thickness and average GCIPL thickness.

Abstract
PURPOSE To evaluate spectral-domain optical coherence tomography (SD-OCT) biomarkers associated with ranibizumab injection frequency after 7 monthly doses in the prospective, multicenter SHORE study for macular edema due to retinal vein occlusion (RVO). DESIGN Prospective phase IV clinical trial data. METHODS Post hoc analysis of 95 patients who received 7 monthly doses of ranibizumab followed by either pro re nata (PRN) or nonrandomized monthly injections from months 7-15 in eyes with macular edema secondary to RVO. Baseline SD-OCT biomarkers assessed include central subfield thickness (CST), epiretinal membrane presence, intraretinal and subretinal fluid, hyperreflective foci, disorganization of retinal inner layers (DRIL), and disruption of the external limiting membrane, ellipsoid zone, or interdigitation zone. Univariate and multivariable regression analyses evaluated the association between SD-OCT biomarkers and ranibizumab injection frequency. RESULTS Mean age of patients was 65.3 (SD, 12.7) years. Overall, 57.9% had BRVO/HRVO and 42.1% of eyes had CRVO. Mean BCVA improved (+17.5 [SD, 1.2] Early Treatment of Diabetic Retinopathy Study [ETDRS] letters) during the 7-month fixed dosing period, remaining stable from baseline (+20.1 [SD, 1.5] ETDRS letters) during the PRN phase from months 7-15. The mean number of PRN injections was 4.32 (SD, 2.35). On multivariate regression, greater baseline DRIL (β = 0.021, P = .0275) and higher CST at month 3 (β = 0.01, P < .001) were associated with a higher total number of PRN injections. CONCLUSION Greater baseline DRIL and higher CST at 3 months after starting ranibizumab treatment are associated with more frequent ranibizumab injections in PRN-treated patients with macular edema due to RVO.

Abstract
PURPOSE To evaluate the vision-related quality of life (VR-QOL) before and after intravitreal ranibizumab injections (IVR) for central retinal vein occlusion (CRVO) and to investigate subscale items of VR-QOL in detail. STUDY DESIGN A multicenter, open-label, prospective and comparative study. METHODS Twenty-three patients with treatment naïve CRVO and 22 age-matched normal controls were included. VR-QOL was assessed by 25-Item Visual Function Questionnaire (VFQ-25) before and up to 12 months post-treatment. The VFQ-25 composite score and 12 subscales were compared between CRVO patients and normal controls. RESULTS The VFQ-25 composite scores of CRVO patients showed significant improvement throughout the treatment period compared with baseline. The VFQ-25 composite scores both before and after treatment for CRVO were significantly lower than in normal controls. The subscale items, including general health, general vision, near activities, social functioning, mental health, role difficulties, dependency, and peripheral vision in CRVO, were significantly lower than in the normal controls even after treatment. CONCLUSION Vision-related QOL was low in patients with CRVO before treatment and improved with IVR. In spite of the improvements, several subscale items remained lower than in normal controls following treatment. Attention should be paid to the patients with CRVO and their decreased visual, social and psychological QOL.

Abstract
PURPOSE Evaluate optical coherence tomography angiography (OCT-A) features in retinal vein occlusions (RVO) associated with visual outcomes after anti-VEGF. METHODS Analytical observational study performed in eyes with macular edema secondary to RVO treated with anti-VEGF, with at least 6 months of follow-up. Bradley et al. classification of macular ischemia was used. Logistic regression analysis was used to investigate associations between final best-corrected visual acuity (BCVA) and OCT-A. RESULTS A total of 62 eyes, 61 subjects, mean age of 70 ± 12,6 years were included. Median follow up time 21,2 months (IQR 24.8), 53,2% had central retinal vein occlusion (CRVO) and 46,8% branch retinal vein occlusion (BRVO). Median BCVA pre-treatment was 0,84 logMAR (IQR 0,83) and post-treatment 0,47 logMAR (IQR 0,52). BCVA improved at the end of follow-up (p = 0,01), as well as central retinal thickness (CRT) (p = 0,02). Regarding capillary densities (CD), there was a decrease for both plexus, Superficial CD (p = 0,01) and Deep CD (p = 0,01), being more involved the superficial plexus. The lower the capillary density in both plexus, the worse BCVA, Superficial CD (r - 0,27, p = 0,03) and Deep CD (r - 0,29, p = 0,02). Media FAZ pre-treatment was 0,30 mm2 (IQR 0,23), with enlargement to 0,37 mm2 (IQR 0,32) (p = 0,01) post-treatment. Preservation of External Limiting Membrane/ Ellipsoid Zone (ELM/EZ) was seen in 60% of subjects (n = 37). The majority had grade 3 macular ischemia. Variables that best explain visual results were, baseline visual acuity (p = 0,01), pre-treatment CRT (p = 0,02) and pretreatment foveal superficial CD (p = 0,02). CONCLUSIONS Variables that best explain final vision after anti-VEGF were baseline visual acuity, CRT and foveal superficial CD.

A comparison of deep learning U-Net architectures for posterior segment OCT retinal layer segmentation. Sci Rep 2022; 12:14888. [PMID: 36050364 PMCID: PMC9437058 DOI: 10.1038/s41598-022-18646-2] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Accepted: 08/17/2022] [Indexed: 11/08/2022] Open
Abstract
Deep learning methods have enabled a fast, accurate and automated approach for retinal layer segmentation in posterior segment OCT images. Due to the success of semantic segmentation methods adopting the U-Net, a wide range of variants and improvements have been developed and applied to OCT segmentation. Unfortunately, the relative performance of these methods is difficult to ascertain for OCT retinal layer segmentation due to a lack of comprehensive comparative studies, and a lack of proper matching between networks in previous comparisons, as well as the use of different OCT datasets between studies. In this paper, a detailed and unbiased comparison is performed between eight U-Net architecture variants across four different OCT datasets from a range of different populations, ocular pathologies, acquisition parameters, instruments and segmentation tasks. The U-Net architecture variants evaluated include some which have not been previously explored for OCT segmentation. Using the Dice coefficient to evaluate segmentation performance, minimal differences were noted between most of the tested architectures across the four datasets. Using an extra convolutional layer per pooling block gave a small improvement in segmentation performance for all architectures across all four datasets. This finding highlights the importance of careful architecture comparison (e.g. ensuring networks are matched using an equivalent number of layers) to obtain a true and unbiased performance assessment of fully semantic models. Overall, this study demonstrates that the vanilla U-Net is sufficient for OCT retinal layer segmentation and that state-of-the-art methods and other architectural changes are potentially unnecessary for this particular task, especially given the associated increased complexity and slower speed for the marginal performance gains observed. Given the U-Net model and its variants represent one of the most commonly applied image segmentation methods, the consistent findings across several datasets here are likely to translate to many other OCT datasets and studies. This will provide significant value by saving time and cost in experimentation and model development as well as reduced inference time in practice by selecting simpler models.

Int J Mol Sci 2022; 23:ijms23147585. [PMID: 35886930 PMCID: PMC9319632 DOI: 10.3390/ijms23147585] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2022] [Revised: 07/04/2022] [Accepted: 07/05/2022] [Indexed: 11/18/2022] Open
Abstract
This work aims to summarize predictive biomarkers to guide treatment choice in DME. Intravitreal anti-VEGF is considered the gold standard treatment for centers involving DME, while intravitreal steroid treatment has been established as a second-line treatment in DME. However, more than 1/3 of the patients do not adequately respond to anti-VEGF treatment despite up to 4-weekly injections. Not surprisingly, insufficient response to anti-VEGF therapy has been linked to low-normal VEGF levels in the serum and aqueous humor. These patients may well benefit from an early switch to intravitreal steroid treatment. In these patients, morphological biomarkers visible in OCT may predict treatment response and guide treatment decisions. Namely, the presence of a large amount of retinal and choroidal hyperreflective foci, disruption of the outer retinal layers and other signs of chronicity such as intraretinal cysts extending into the outer retina and a lower choroidal vascular index are all signs suggestive of a favorable treatment response of steroids compared to anti-VEGF. This paper summarizes predictive biomarkers in DME in order to assist individual treatment decisions in DME. These markers will help to identify DME patients who may benefit from primary dexamethasone treatment or an early switch.

Abstract
Purpose
Assess correlation between change in central subfield thickness (CST) and change in best-corrected visual acuity (BCVA) in eyes with macular edema due to retinal vein occlusion (RVO) that received intravitreal aflibercept injections (IAI). Methods Post hoc analysis of COPERNICUS and GALILEO trials for CRVO and VIBRANT trial for BRVO with relationships determined using Pearson correlation coefficient. Results In COPERNICUS, correlations (r) between change in CST and change in BCVA from baseline at weeks 12, 24, 52, and 100 were −0.36 (95% CI: −0.52, −0.18; P < 0.001), −0.38 (95% CI: −0.53, −0.20; P < 0.001), −0.44 (95% CI: −0.58, −0.27; P < 0.001), and −0.41 (95% CI: −0.56, −0.23; P < 0.001), respectively. CST changes accounted for only 21% of the variance in BCVA changes; every 100-µm decrease in CST was associated with a 2.1-letter increase in BCVA (P = 0.003). Similar findings were noted for GALILEO (r, −0.45 to −0.23) and VIBRANT (r, −0.36 to −0.32) trials. Conclusion In eyes treated with IAI for macular edema due to RVO, correlation between change in CST and change in BCVA was weak to moderate. While change in CST may be helpful in determining the need for anti-VEGF therapy, these findings do not support using changes in CST as a surrogate for changes in visual acuity outcomes. ![]() Supplementary Information The online version contains supplementary material available at 10.1007/s00417-022-05697-4.

Abstract
This review describes the current state of knowledge oт the phenomenon of disorganization of retinal inner layers. DRIL is characterized by alteration of microcirculation in retinal capillary plexuses detected with optical coherence tomography angiography, alteration of several inner layers of the retina with the inability to differentiate them on optical coherence tomography, and by an impact on the quality of vision. Disorganization of retinal inner layers occurs in a number of different vascular retinal disorders, which indicates its importance as a clinical biomarker and clinical significance. However, the literature data on disorganization of retinal inner layers are still limited, and questions about the pathogenesis of this disease warrant further investigations.

Abstract
The second most prevalent cause of retinal vascular disease is retinal vein occlusion (RVO). RVO raises intravascular pressure in the capillary and veins, triggering vessel barrier collapse and subsequent leaking of blood or plasma components into the tissue (edema). Macular edema (ME) is a major complication of RVO that results in significant visual impairment. Laser therapy, intravitreal steroid injections, and vascular endothelial growth factor (VEGF) inhibitors are the major therapeutic techniques. Different therapies reduce ME of RVO and improve visual activity. However, some people have no impact on the resolution of ME, while others have a poor visual prognosis despite full ME cure. There are many investigators who studied the relationship between indicators of various instruments with visual activity. However, a summary of those findings is currently lacking. Therefore, we will focus on the predictive factors of different studies associated with positive visual activity outcomes, which would be very useful and important to help address both treatment expectations and methods for patients with RVO.

Abstract
PURPOSE To quantify ellipsoid zone (EZ) changes in integrity after epiretinal membrane (ERM) surgery, correlate findings to visual acuity, and determine predictors for prognosis. METHODS A post hoc analysis of eyes undergoing ERM surgery pooled from the prospective DISCOVER intraoperative optical coherence tomography study and eyes undergoing conventional ERM surgery without intraoperative optical coherence tomography. Quantitative EZ features were extracted using a multilayer machine learning enabled automated segmentation platform after image analyst review/correction for segmentation accuracy. Visual acuity and EZ integrity were quantitatively assessed and correlated before and after ERM surgery. Multiple linear regression was performed to assess preoperative visual acuity and EZ features as predictors for improvement in visual acuity or EZ integrity. RESULTS There were 177 eyes from 177 subjects that underwent ERM surgery from the DISCOVER and conventional arms. Improvement in visual acuity and multiple EZ integrity features was noted after ERM surgery, including EZ partial attenuation and EZ-retinal pigment epithelium (RPE) volume (P < 0.05). A reduction in EZ partial attenuation and increase in EZ-RPE central subfield thickness (EZ-RPE CST) was significantly correlated with improved visual acuity after ERM surgery (P < 0.05). More robust EZ-RPE CST at baseline predicted visual acuity improvement after ERM peel in regression modeling (β = 0.005, P < 0.05). CONCLUSIONS Longitudinal assessment of EZ features demonstrates significant postoperative improvement in multiple EZ integrity metrics after ERM surgery. Improving EZ integrity was correlated to improving the visual acuity. Ellipsoid zone integrity and visual acuity were significant predictors in regression modeling and may have value in clinical prognostication.

Abstract
Introduction To evaluate the anatomical and functional outcomes of pars plana vitrectomy (PPV) and epiretinal membrane (ERM) peeling in patients with retinal vein occlusion (RVO) and secondary ERM. Methods Retrospective, multicenter study including patients with RVO and ERM who underwent PPV and ERM peeling with or without phacoemulsification. Demographic, clinical, surgical, and optical coherence tomography (OCT) features were recorded at the time of ERM peeling (baseline). Best-corrected visual acuity (BCVA) and central macular thickness (CMT) were longitudinally collected up to 36 months after surgery. Clinical factors associated with BCVA and CMT and disappearance of macular edema during follow-up were investigated. Results Twenty-one eyes of 21 patients with a median follow-up of 18 months were included. The BCVA improved significantly after ERM peeling (baseline vs. 24 months, p = 0.01). Absence of the external liming membrane/ellipsoid zone on OCT was associated with worse visual outcomes (regression estimate [95% confidence interval, CI] = 0.93 [0.39–1.48] logMAR, p = 0.004). Eyes with disorganization of the inner retinal layers at baseline had higher CMT values at each visit (regression estimate [95% CI] = 114.1 [78.9–219.4] μm, p = 0.004). Older age at the time of RVO (p = 0.03) and branch RVO (p = 0.04) were risk factors for persistent macular edema after ERM removal. Conclusion PPV and ERM removal provided encouraging functional and morphological results in eyes with RVO, with disappearance of macular edema in most eyes. The integrity of the outer retina and preservation of inner retinal segmentation were associated with better visual and anatomical outcomes after ERM removal, respectively.

Abstract
Eye diseases and injuries constitute a significant clinical problem worldwide. Safe and effective delivery of drugs to the eye is challenging mostly due to the presence of ocular barriers and clearance mechanisms. In everyday practice, the traditional eye drops, gels and ointments are most often used. Unfortunately, they are usually not well tolerated by patients due to the need for frequent use as well as the discomfort during application. Therefore, novel drug delivery systems with improved biopharmaceutical properties are a subject of ongoing scientific investigations. Due to the developments in microtechnology, in recent years, there has been a remarkable advance in the development of microneedle-based systems as an alternative, non-invasive form for administering drugs to the eye. This review summarizes the latest achievements in the field of obtaining microneedle ocular patches. In the manuscript, the most important manufacturing technologies, microneedle classification, and the research studies related to ophthalmic application of microneedles are presented. Finally, the most important advantages and drawbacks, as well as potential challenges related to the unique anatomy and physiology of the eye are summarized and discussed.

Abstract
UNLABELLED Malignant arterial hypertension is a clinical syndrome characterized by severe diastolic arterial hypertension with signs of ischemic damage to various organs. In some malignant arterial hypertension cases, thrombotic microangiopathy occurs - a rare life-threatening condition characterized by multiple systemic thrombosis of the microvasculature, including in the eyes, which can be clarified by optical scanning of the retina. PURPOSE To determine markers of retinal ischemia in the eyes with thrombotic microangiopathy associated with malignant arterial hypertension. MATERIAL AND METHODS The study included 6 patients (12 eyes) with thrombotic microangiopathy associated with malignant arterial hypertension who were examined by optical coherence tomography (OCT) and OCT angiography (OCT-A). All patients suffered from renal dysfunction, which etiology was determined by renal biopsy verifying the presence of renal thrombotic microangiopathy in all cases. RESULTS According to OCT findings, there were bilateral local foci of thinning of the inner nuclear layer with elevation of the outer plexiform and outer nuclear layers of the retina in 5 out of 6 patients (83%). OCT-A revealed that in most cases (67%), these changes had perivascular localization and corresponded to the areas of attenuation of the deep capillary plexus. A statistically significant thinning of the inner nuclear layer of the retina was found in thrombotic microangiopathy associated with malignant arterial hypertension in comparison with the control group. CONCLUSION Presence of renal thrombotic microangiopathy confirmed by renal biopsy and the anatomical similarity of the microvasculature of the kidneys and the eyes, give basis to consider the foci of «chronic» paracentral acute middle maculopathy detected with OCT in patients with malignant arterial hypertension as biomarkers of thrombotic microangiopathy of the eye.

Abstract
CLINICAL RELEVANCE With equivalent inner retinal thickness measurements compared to a more conventional composite optical coherence tomography (OCT) protocol, Widefield optical coherence tomography (WF-OCT) is a clinically viable, time-saving option facilitating detection of ocular pathologies within the central 55° of the retina. PURPOSE To compare ganglion cell-inner plexiform layer (GCIPL) thicknesses obtained using a single WF-OCT scan and standard composite OCT scans acquired in 9 fields of gaze (9F-OCT). METHODS Thirteen healthy participants underwent WF-OCT and 9F-OCT using the Spectralis OCT. The GCIPL was automatically segmented with a manual review for 9F-OCT and was manually segmented for WF-OCT. After registration, differences in GCIPL thicknesses were compared using 95% confidence intervals computed from one-sample t-tests and Bland-Altman analyses. Location-specific differences in B-scan tilt were analysed using Spearman correlations and linear regression models. To determine whether B-scan tilt influences GCIPL measurements, regression models of tilt versus differences between perpendicular and axial GCIPL thickness were applied. RESULTS While scattered locations demonstrated significant GCIPL thickness differences between WF-OCT and 9F-OCT, most differences did not exceed the axial pixel resolution of the instrument of 3.87 µm. Bland-Altman analyses indicated no notable bias using WF-OCT. Moderate correlations indicating significant location-specific differences in B-scan tilt were observed for temporal, central and inferior B-scans (r = -0.62 to 0.72), with linear regression models predicting a maximum difference in the tilt of 4.65°. The quadratic regression model indicated that at tilts greater than 27.3°, perpendicular GCIPL measurements become increasingly thin relative to axial measurements. CONCLUSIONS GCIPL thicknesses and B-scan tilts from WF-OCT are comparable to 9F-OCT, indicating that WF-OCT can be applied clinically to obtain valid inner retinal OCT measurements over 55° of the central retina with relative ease. However, for peripheral locations, B-scan tilt may need to be considered when measuring GCIPL thicknesses.

Abstract
Purpose: Epiretinal membrane (ERM) is a common retinal finding for patients older than 50 years. Disorganization of the retinal inner layers (DRIL) has emerged as a novel predictor of poor visual acuity (VA) in eyes with inner retinal pathology. The aim of our study is to correlate preoperative DRIL with visual outcomes after ERM surgery. Methods: Medical records and optical coherence tomography (OCT) images of 81 pseudophakic patients who underwent treatment of idiopathic ERM were reviewed. Preoperative DRIL on OCT was correlated with VA at baseline and at 3 and 6 months after ERM surgery. DRIL was defined as the loss of distinction between the ganglion cell–inner plexiform layer complex, inner nuclear layer, and outer plexiform layer. DRIL severity was based on its extent within the central 2-mm region of a transfoveal B-scan (absent/mild: <one-third, severe: >one-third horizontal width). Results: Review of preoperative OCT showed severe DRIL in 41% and absent/mild DRIL in 59%. Severe DRIL was associated with worse baseline VA ( P < .001). Preoperative VA and DRIL status at baseline were both predictors of postoperative VA at follow-up time points ( P < .001). Severe DRIL was associated with significantly less improvement in VA at 6 months (–0.23 logMAR for absent/mild vs –0.14 for severe DRIL). Conclusions: Presence of severe preoperative DRIL correlates with worse baseline VA in patients with ERM and reduced VA improvement at 6 months. DRIL can be a strong predictor of long-term poor visual outcomes in ERM surgery.

Abstract
Visual field (VF) testing is an essential component of the neurological examination. The differential diagnosis of VF defects depends on relating this measure of afferent visual function to the structure of the visual pathway and optical coherence tomography (OCT) is an invaluable tool for detailed structural evaluation of the optic nerve and retina. This review describes the ways in which interpretation of VF and OCT can be used together to increase the accuracy of the localization of lesions along the visual pathway. Lesions of the anterior visual pathway (originating in ganglion cells or nerve fibre layer of the retina or optic nerve) will typically produce defects that respect the horizontal midline, reflecting the arcuate path of the ganglion cell axons as they travel to the optic nerve. OCT of peripapillary retinal nerve fibre layer and ganglion cell complex (GCC) will typically demonstrate irreversible thinning in compressive and demyelinating lesions affecting anterior visual pathway. Chiasmal lesions produce highly localizable VF defects (junctional scotoma and bitemporal hemianopia) which correspond to the thinning of nasal portion of GCC. Lesions of the optic tract result in incongruous homonymous hemianopia on VF with corresponding hemianopic thinning on GCC developing within months. Lesions affecting optic radiations usually produce more congruous homonymous VF defects and can also produce homonymous thinning on GCC, however, this takes much longer to develop as trans-synaptic degeneration at the lateral geniculate body must occur.

Abstract
Background To evaluate macular microstructure alterations in the parafoveal nonperfusion areas of eyes with branch retinal vein occlusions (BRVO), and to investigate their impact on retinal sensitivity. Methods This was a cross-sectional study including thirteen BRVO patients with parafoveal capillary nonperfusion areas (NPA). Multiple modalities including microperimetry, optical coherence tomography angiography, and optical coherence tomography were performed to measure retinal sensitivity and thickness, and to identify the microstructure changes and perfusion status. Results The retinal sensitivity and thickness in the NPA were significantly lower than those in the perfusion areas (PA) (P = 0.001, P = 0.003). Microstructure changes, including disorganization of the retinal inner layers (DRIL), disruption of the outer retinal layers, and cysts were more frequently observed in NPA (P = 0.002, P = 0.018, P = 0.068). Within NPA, the retinal sensitivity of areas with DRIL, and outer retinal layers disruption was significantly lower than that of the areas without DRIL (P = 0.016), and with intact outer retinal layers (P < 0.001), respectively. 1dB increase in retinal sensitivity was correlated with 2.2 μm (95 % confidence interval, 1.71–2.7) increase of the thickness (P < 0.001). The retinal sensitivity was significantly lower at points with both DRIL and outer retinal layers disruption than at the points with DRIL or outer retina layers disruption alone (P = 0.001, P = 0.001). Conclusions Alterations in the macular microstructure are associated with ischemia, especially DRIL. DRIL and outer retinal layers disruption are imaging features that have important implications for local retinal sensitivity in the ischemic areas, and where the microstructure of both inner and outer retinal layers is disrupted the function is further destructed.

Abstract
PURPOSE To evaluate associations between functional and structural measurements in patients with non-acute VKHD. METHODS In this cross-sectional study, 16 non-acute VKHD patients (32 eyes; 14 female) were evaluated with multifocal electroretinogram (mfERG), standardized automated perimetry (SAP) and optical coherence tomography (OCT)examinations. All included patients had a minimum 12 months of follow-up from acute onset and were participants of an ongoing prospective study since acute phase with systematic clinical imaging evaluations and electroretinogram examinations within a predefined treatment. Age- and gender-matched controls were included. Main outcomes were functional and structural abnormalities and their correlation; secondary outcome was correlation of these findings with clinical characteristics, including fundus abnormalities. RESULTS SAP and mfERG parameters were significantly worse in patients than in controls. Fourteen eyes (43.7%) had disrupted ellipsoid zone (EZ); visual acuity (VA) was similar between eyes with intact or disrupted EZ. Eyes with intact and disrupted EZ differed significantly concerning N1 and P1 amplitudes and N1 peak time values on mfERG and mean sensitivity (MS), central sensitivity (CS), foveal threshold, visual field index, mean deviation (MD) and pattern standard deviation values on SAP. The area under the curve on receiver operating curves for P1 amplitude was 0.81 (cut-off value = 34.7 nV/deg2 ) and for MD value was 0.84 (cut-off value = -5.2 dB). Central retinal thickness (CRT) significantly correlated with N1 and P1 amplitudes and P1 peak time values on mfERG (r = 0.354, r = 0.442 and r = -0.405, respectively) and MD, MS, CS and fovea threshold (log values) on SAP (r = 0.372, r = 0.406, r = 0.431 and r = 0.414, respectively). Statistically significant associations were found with the presence of peripapillary atrophy and recurrent anterior uveitis with a worse MD value (p = 0.004 and p < 0.001, respectively). CONCLUSION In non-acute VKHD, disrupted EZ and reduced CRT were correlated with impaired mfERG and SAP parameters, even in patients with good VA.

Abstract
Purpose To evaluate the association between ellipsoid zone (EZ) on spectral domain optical coherence tomography (SD-OCT) and visual acuity letter score (VALS) in participants with retinal vein occlusion in the Study of Comparative Treatments for Retinal Vein Occlusion 2. Methods SD-OCT scans of 362 participants were qualitatively assessed at baseline and months 1, 6, 12, and 24 for EZ status as normal, patchy, or absent. The thickness of EZ layer in the central subfield was also obtained using machine learning. Results EZ assessments were not possible at baseline due to signal blockage in >75% of eyes. At month 1, EZ was normal in 37.6%, patchy in 48.1%, and absent in 14.3%. EZ was measurable in 48.7% with a mean area of 0.07 ± 0.16 mm2. Mean VALS was better in eyes without an EZ defect compared to eyes with an EZ defect (P < 0.0001 at all visits). EZ defect at month 1 was associated with poorer VALS at all follow-up visits (P < 0.0001). Conclusions Both qualitative and quantitative assessments of EZ status strongly correlated with VALS. Absence of EZ was associated with poorer VALS at both corresponding and future visits, with larger areas of EZ loss associated with worse VALS. Translational Relevance Assessment of EZ can be used to identify patients with potentially poor response in eyes with retinal vein occlusion.

Abstract
PURPOSE To compare the functional and anatomical outcomes of central retinal vein occlusion (CRVO) according to the presence of glaucoma before the onset of CRVO, and to assess whether pre-existing glaucoma affects the prognosis of CRVO in terms of development and conversion to ischaemic CRVO. METHODS In this retrospective cohort study, patients with treatment-naïve CRVO were enrolled between December 2009 and February 2019. The patients were classified into two groups according to the presence of pre-existing primary open-angle glaucoma at CRVO diagnosis. We reviewed medical records regarding basic demographics, ocular characteristics and treatments. The effects of pre-existing glaucoma on the occurrence of ischaemic CRVO were also investigated using Cox proportional hazard models. RESULTS Of 166 eyes from 166 patients, 26 (15.7%) had pre-existing glaucoma. The pre-existing glaucoma group revealed significantly older (69.4 ± 13.3 versus 56.5 ± 15.9) and lower BCVA at baseline (1.06 ± 0.75 versus 0.64 ± 0.58, logMAR) and final visits (1.56 ± 1.35 versus 0.64 ± 0.48, logMAR) (all p < 0.05) than non-glaucomatous group. In terms of perfusion status of CRVO, the glaucoma group showed higher incidence of ischaemic CRVO (30.8% versus 5.3%, p = 0.052) at initial and last visits as well as more disorganization of retinal inner layers (DRIL) at 3 months (76.0% versus 49.6%, p = 0.015). Pre-existing glaucoma (hazard ratio (HR) = 2.141, p = 0.014), lower vision at baseline (HR = 2.071, p = 0.001) and DRIL at 3 months (HR = 2.905, p = 0.011) were significant risk factors for the occurrence of ischaemic CRVO. CONCLUSION In patients with CRVO, pre-existing glaucoma was associated with poorer visual and anatomical outcomes, and played as a significant risk factor for the development and conversion to ischaemic CRVO with lower vision and presence of DRIL at early phase of CRVO.

Intravitreal ranibizumab versus aflibercept versus bevacizumab for macular oedema due to central retinal vein occlusion: the LEAVO non-inferiority three-arm RCT. Health Technol Assess 2021; 25:1-196.

Abstract
BACKGROUND Licensed ranibizumab (0.5 mg/0.05 ml Lucentis®; Novartis International AG, Basel, Switzerland) and aflibercept (2 mg/0.05 ml Eylea®; Bayer AG, Leverkusen, Germany) and unlicensed bevacizumab (1.25 mg/0.05 ml Avastin®; F. Hoffmann-La Roche AG, Basel, Switzerland) are used to treat macula oedema due to central retinal vein occlusion, but their relative clinical effectiveness, cost-effectiveness and impact on the UK NHS and Personal Social Services have never been directly compared over the typical disease treatment period. OBJECTIVE The objective was to compare the clinical effectiveness and cost-effectiveness of three intravitreal antivascular endothelial growth factor agents for the management of macula oedema due to central retinal vein occlusion. DESIGN This was a three-arm, double-masked, randomised controlled non-inferiority trial. SETTING The trial was set in 44 UK NHS ophthalmology departments, between 2014 and 2018. PARTICIPANTS A total of 463 patients with visual impairment due to macula oedema secondary to central retinal vein occlusion were included in the trial. INTERVENTIONS The participants were treated with repeated intravitreal injections of ranibizumab (n = 155), aflibercept (n = 154) or bevacizumab (n = 154). MAIN OUTCOME MEASURES The primary outcome was an increase in the best corrected visual acuity letter score from baseline to 100 weeks in the trial eye. The null hypothesis that aflibercept and bevacizumab are each inferior to ranibizumab was tested with a non-inferiority margin of -5 visual acuity letters over 100 weeks. Secondary outcomes included additional visual acuity, and imaging outcomes, Visual Function Questionnaire-25, EuroQol-5 Dimensions with and without a vision bolt-on, and drug side effects. Cost-effectiveness was estimated using treatment costs and Visual Function Questionnaire-Utility Index to measure quality-adjusted life-years. RESULTS The adjusted mean changes at 100 weeks in the best corrected visual acuity letter scores were as follows - ranibizumab, 12.5 letters (standard deviation 21.1 letters); aflibercept, 15.1 letters (standard deviation 18.7 letters); and bevacizumab, 9.8 letters (standard deviation 21.4 letters). Aflibercept was non-inferior to ranibizumab in the intention-to-treat population (adjusted mean best corrected visual acuity difference 2.23 letters, 95% confidence interval -2.17 to 6.63 letters; p = 0.0006), but not superior. The study was unable to demonstrate that bevacizumab was non-inferior to ranibizumab in the intention-to-treat population (adjusted mean best corrected visual acuity difference -1.73 letters, 95% confidence interval -6.12 to 2.67 letters; p = 0.071). A post hoc analysis was unable to demonstrate that bevacizumab was non-inferior to aflibercept in the intention-to-treat population (adjusted mean best corrected visual acuity difference was -3.96 letters, 95% confidence interval -8.34 to 0.42 letters; p = 0.32). All per-protocol population results were the same. Fewer injections were required with aflibercept (10.0) than with ranibizumab (11.8) (difference in means -1.8, 95% confidence interval -2.9 to -0.8). A post hoc analysis showed that more bevacizumab than aflibercept injections were required (difference in means 1.6, 95% confidence interval 0.5 to 2.7). There were no new safety concerns. The model- and trial-based cost-effectiveness analyses estimated that bevacizumab was the most cost-effective treatment at a threshold of £20,000-30,000 per quality-adjusted life-year. LIMITATIONS The comparison of aflibercept and bevacizumab was a post hoc analysis. CONCLUSION The study showed aflibercept to be non-inferior to ranibizumab. However, the possibility that bevacizumab is worse than ranibizumab and aflibercept by 5 visual acuity letters cannot be ruled out. Bevacizumab is an economically attractive treatment alternative and would lead to substantial cost savings to the NHS and other health-care systems. However, uncertainty about its relative effectiveness should be discussed comprehensively with patients, their representatives and funders before treatment is considered. FUTURE WORK To obtain extensive patient feedback and discuss with all stakeholders future bevacizumab NHS use. TRIAL REGISTRATION Current Controlled Trials ISRCTN13623634.

Abstract
Purpose: This work evaluated the longitudinal dynamics of ellipsoid zone (EZ) integrity in retinal vein occlusion (RVO) with macular edema and their relation to outcomes. Methods: Clinical characteristics and optical coherence tomography data of patients with RVO and associated macular edema were collected at baseline and at 3 and 12 months. Macular cube scans were exported into EZ and retinal-layer analysis software. Longitudinal EZ parameters and visual acuity (VA) outcomes were regressed and correlated. Results: The study included 108 eyes of 108 patients; all eyes were treated with antivascular endothelial growth factor therapy at the baseline visit. VA improved from 20/97 at baseline to 20/52 at 3 months and 12 months ( P < .001), correlating with EZ integrity at each time point ( P < .001). At 12 months following initiation of antivascular endothelial growth factor therapy, EZ partial attenuation and EZ total attenuation improved over 12 months from 16.4% to 8.5% ( P < .001) and from 12.3% to 5.9% ( P < .001), respectively. VA improvement from baseline to 12 months correlated with improvement of EZ partial and total attenuation ( P < .001). Baseline EZ characteristics did not predict VA outcomes, but at 3 months, EZ parameters did predict improvement in visual outcomes by 12 months ( P < .01). Conclusions: EZ and outer retinal integrity are correlated with functional outcomes in RVO. Following treatment, EZ integrity improves and is associated with functional improvement. In RVO baseline, EZ features were not associated with 1-year VA outcomes, but evaluation of EZ integrity at 3 months was linked to 1-year outcomes.

Abstract
PURPOSE To evaluate the association between baseline demographic and spectral domain OCT (SD-OCT) features with visual acuity (VA) in the Study of COmparative Treatments for REtinal Vein Occlusion 2 (SCORE2) over 2 years. DESIGN Post hoc analysis of prospective clinical trial data. PARTICIPANTS A total of 362 SCORE2 participants with macular edema secondary to central retinal (CRVO) or hemiretinal vein occlusion (HRVO). METHODS Spectral domain OCT volume scans were assessed at the SCORE2 reading center at baseline, month 01 (M01), month 06 (M06), month 12 (M12), and month 24 (M24) for central subfield thickness (CST), subretinal fluid, intraretinal fluid, vitreoretinal interface abnormalities, disorganization of retinal inner layers (DRIL), and ellipsoid zone (EZ) within the central subfield (CSF). MAIN OUTCOME MEASURES Visual acuity at M06, M12, and M24. RESULTS Mean baseline age was 68.9 years. Mean VA at M01 was 63.2 letters, and CST was 299.7 μm. At M01, subretinal fluid was seen in 28.5% intraretinal fluid in 67.2%, DRIL was seen in 73.8%, mostly within the CSF, and the EZ was absent in 9.8 and patchy in 31.7%. In multivariate analysis including all M01 demographics and SD-OCT parameters and their association with VA at M06, M12, and M24, VA at M01 remained significant across all time points up to M24 (P < 0.001). CONCLUSIONS In this 2-year follow-up of eyes that were treated with both per protocol and off protocol for RVO, VA at M01 was an important predictor of long-term vision and change in vision. Establishing predictors of visual recovery helps identify causes for poor responders to treatment in patients with RVO.

[PMID: 33489352 PMCID: PMC7803262 DOI: 10.1155/2020/9861086] [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: 07/06/2020] [Revised: 12/06/2020] [Accepted: 12/11/2020] [Indexed: 11/30/2022] Open
Abstract
Purpose We aimed to describe the visual prognosis of eyes with ectopic inner foveal layers (EIFLs) after epiretinal membrane (ERM) surgery. Methods This retrospective study enrolled patients diagnosed with stage 3 ERM based on the EIFL staging scheme who underwent ERM surgery with a minimum follow-up period of 12 months. Central foveal thickness (CFT), EIFL thickness, and the length of the ellipsoid zone defect were evaluated at baseline and at 1 month, 6 months, and 12 months after surgery based on pre- and postoperative swept-source optical coherence tomography (OCT) images. The association of EIFL thickness and other OCT parameters with pre- and postoperative best-corrected visual acuity (BCVA) was analyzed. Results Sixty-nine eyes with stage 3 ERMs were analyzed. Preoperative BCVA was correlated with preoperative CFT (r = 0.517, p < 0.001) and preoperative EIFL thickness (r = 0.652, p < 0.001). At 12 months, postoperative BCVA was correlated negatively with preoperative CFT (r = 0.470, p=0.016) and preoperative EIFL thickness (r = 0.582, p=0.004). The improvement in BCVA was not associated with postoperative reduction in CFT (p=0.06), although it was significantly associated with postoperative reduction in EIFL thickness (r = 0.635, p=0.007). Conclusions EIFL thickness should be considered a negative prognostic factor for postoperative anatomical and functional recovery in patients with stage 3 ERMs.

Br J Ophthalmol 2020; 106:241-245. [PMID: 33172863 DOI: 10.1136/bjophthalmol-2020-317615] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2020] [Revised: 10/07/2020] [Accepted: 10/20/2020] [Indexed: 12/25/2022]
Abstract
BACKGROUND/AIMS To determine if disorganisation of retinal inner layers (DRIL) is associated with reduced contrast sensitivity (CS) in patients with retinal vein occlusion (RVO) with a history of macular oedema (ME). METHODS Prospective, observational cohort study. Patients with a history of ME secondary to central retinal vein occlusion (CRVO) or branch retinal vein occlusion (BRVO) from October 2017 to July 2019 at a single institution were included. Patients underwent complete ophthalmic examination, spectral domain optical coherence tomography (SD-OCT) and CS testing using the quick contrast sensitivity function (qCSF) method. Eyes with coexisting macular disease were excluded. SD-OCT images were analysed for presence and extent of DRIL, intraretinal fluid (IRF), subretinal fluid (SRF), hyperreflective foci, epiretinal membrane (ERM), external limiting membrane (ELM) disruption, ellipsoid zone (EZ) disruption, central macular thickness (CMT) and central foveal thickness (CFT). Multivariable mixed-effect linear regressions were performed for the area under the log contrast sensitivity function (AULCSF) using Stata (StataCorp). P values <0.05 were considered significant. RESULTS 58 visits from 31 patients were included (1.9±1.2 visits per patient). 29 (50%) were for CRVO. The average age was 63.9±10.5 years. On multivariable analysis, DRIL extent (p<0.001), CMT (p=0.007), CFT (p=0.024) and moderate cataract (p=0.001) were significantly associated with worse AULCSF. CONCLUSIONS DRIL extent is associated with reduced CS in eyes with ME secondary to RVO. DRIL is an imaging feature that has important implications for visual function.

Abstract
PURPOSE The aim of this study was to evaluate the effect of the dexamethasone intravitreal (DEX) implant on the external limiting membrane (ELM) and ellipsoid zone (EZ) integrity in treatment-naïve patients with macular edema (ME) secondary to retinal vascular disease (RVD). METHODS This is a retrospective study conducted on patients with ME secondary to RVD, who underwent a DEX implant. RESULTS One-hundred eyes were included. Mean age was 70.3 ± 11.1 years. Mean ELM integrity significantly improved from 1,575.9 ± 285.9 μm at baseline to 1,711.7 ± 244.0 μm at month 3 (p < 0.0001). Similarly, there was a significant improvement in EZ integrity from baseline to month 3 (1,531.5 ± 317.1 vs. 1,694.3 ± 252.8 μm, respectively, p < 0.0001). At month 3, mean visual acuity (VA) gain was 9.9 ± 14.1 letters (p < 0.0001). Mean central retinal thickness (CRT) significantly decreased by -193.2 ± 185.7 μm from baseline to month 3 (p < 0.0001). Mean changes in VA and CRT were significantly correlated with baseline ELM integrity (p = 0.0065 and p = 0.0046, respectively) and EZ integrity (p = 0.0300 and p = 0.0035, respectively). At month 3, the proportion of eyes which had an intact ELM (mean difference 16.0%, 95% CI 5.4-26.4%, p = 0.0033) and EZ (mean difference 12.0%, 95% CI 1.8-22.1%, p = 0.0210) was significantly higher than at baseline. CONCLUSIONS DEX implant was able to significantly improve ELM and EZ integrity in naïve patients with ME.

Abstract
Background Given the two different kinds of epiretinal membranes, this study aimed to compare both the structural and functional outcomes of lamellar macular holes with and without lamellar hole-associated epiretinal proliferation (LHEP) after surgery. Method Publications up to July 2020 that compared the surgical outcomes of lamellar macular hole with and without LHEP were included. Forest plots were created by using a weighted summary of proportion meta-analysis. Fixed or random effects models were used on the basis of I2 heterogeneity estimates. Meanwhile, to evaluate the stability of the meta-analysis, a sensitivity analysis was carried out. Results Eight pertinent publications that contained a total of 176 eyes without LHEP and 173 eyes with LHEP were included. They were all retrospective studies and had a follow-up of at least 6 months. In all studies, the preoperative best corrected visual acuity showed no significant differences between the two groups, and the visual acuity improved in both groups after surgery. The pooled result for the improved best corrected visual acuity was 0.18 (95% confidence interval (CI), 0.10 to 0.26; P < 0.01) between the with and without LHEP groups. The restored ellipsoid zone odds ratio was 0.80 (95% CI, 0.26 to 2.44; P = 0.69) for the group with LHEP compared to the group without LHEP. Conclusion Patients without LHEP had better postoperative visual acuity than patients with LHEP. No significant difference in restored ellipsoid zone was found between the two groups.

Comparison of SDOCT Scan Types for Grading Disorganization of Retinal Inner Layers and Other Morphologic Features of Diabetic Macular Edema. Transl Vis Sci Technol 2020; 9:45. [PMID: 32855891 PMCID: PMC7422902 DOI: 10.1167/tvst.9.8.45] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2020] [Accepted: 06/24/2020] [Indexed: 11/28/2022] Open
Abstract
Purpose To assess grading reproducibility of disorganization of the retinal inner layers (DRIL) and other morphologic features of diabetic macular edema (DME) across spectral domain optical coherence tomography (SDOCT) instruments and scan types. Methods A cross-sectional study enrolled participants with current or recent center-involved DME. In group A (27 eyes), we obtained two Cirrus scans (512 × 128 macular cube [Cube] and high-definition five-line raster [HD 5-Line]) and two Spectralis scans (high-resolution [HR] and high-speed [HS]). In group B, 26 eyes underwent HR scans and Optovue AngioVue (OP) 3 × 3-mm scans. All scans were graded for type and extent of DRIL, intraretinal cysts, cone outer segment tip visibility, and subretinal fluid (SRF). Results In the total cohort, mean central subfield thickness was 342.9 ± 83.4 µm. Intraclass correlations were high for DRIL extent across the four different imaging settings (HR vs. HS, r = 0.93; HR vs. Cube, r = 0.84, HR vs. HD 5-Line, r = 0.76, HR vs. OP, r = 0.87) and ranged from good to excellent for intraretinal cyst and SRF area. There were significantly smaller mean normalized differences between HR/HS scans versus HR and all other scan modalities (HR/HS vs. HR/Cube, P = 0.02; HR/HD 5-Line, P = 0.0005; HR/OP, P < 0.0001). Conclusions Our data suggest that the reproducibility for SDOCT parameters of DRIL and intraretinal cysts was high across all five SDOCT scan types; thus, evaluation of DRIL is feasible using multiple SDOCT models in eyes with DME. Translational Relevance DME morphological changes can be evaluated on multiple SDOCT devices with good reproducibility, allowing clinicians and researchers flexibility in DME assessment for clinical care and research.

Abstract
Central nervous system ischemic injury features neuronal dysfunction, inflammation and breakdown of vascular integrity. Here we show that activation of endothelial caspase-9 after hypoxia-ischemia is a critical event in subsequent dysfunction of the blood-retina barrier, using a panel of interrelated ophthalmic in vivo imaging measures in a mouse model of retinal vein occlusion (RVO). Rapid nonapoptotic activation of caspase-9 and its downstream effector caspase-7 in endothelial cells promotes capillary ischemia and retinal neurodegeneration. Topical eye-drop delivery of a highly selective caspase-9 inhibitor provides morphological and functional retinal protection. Inducible endothelial-specific caspase-9 deletion phenocopies this protection, with attenuated retinal edema, reduced inflammation and preserved neuroretinal morphology and function following RVO. These results reveal a non-apoptotic function of endothelial caspase-9 which regulates blood-retina barrier integrity and neuronal survival, and identify caspase-9 as a therapeutic target in neurovascular disease. Retinal vein occlusion can cause blindness, and features neuronal dysfunction, inflammation and breakdown of vascular integrity. Here the authors report a non-apoptotic role of endothelial caspase-9 in regulating blood-retina barrier integrity and neuronal survival, which can be therapeutically targeted in a mouse model of retinal vein occlusion.

Abstract
Background and objective To develop a semi-automated, machine-learning based workflow to evaluate the ellipsoid zone (EZ) assessed by spectral domain optical coherence tomography (SD-OCT) in eyes with macular edema secondary to central retinal or hemi-retinal vein occlusion in SCORE2 treated with anti-vascular endothelial growth factor agents. Methods SD-OCT macular volume scans of a randomly selected subset of 75 SCORE2 study eyes were converted to the Digital Imaging and Communications in Medicine (DICOM) format, and the EZ layer was segmented using nonproprietary software. Segmented layer coordinates were exported and used to generate en face EZ thickness maps. Within the central subfield, the area of EZ defect was measured using manual and semi-automated approaches via a customized workflow in the open-source data analytics platform, Konstanz Information Miner (KNIME). Results A total of 184 volume scans from 74 study eyes were analyzed. The mean±SD area of EZ defect was similar between manual (0.19±0.22 mm2) and semi-automated measurements (0.19±0.21 mm2, p = 0.93; intra-class correlation coefficient = 0.90; average bias = 0.01, 95% confidence interval of limits of agreement -0.18–0.20). Conclusions A customized workflow generated via an open-source data analytics platform that applied machine-learning methods demonstrated reliable measurements of EZ area defect from en face thickness maps. The result of our semi-automated approach were comparable to manual measurements.

Abstract
PURPOSE To examine the macular microstructure in macular edema (ME) due to retinal vein occlusion (RVO) in terms of ischemic or nonischemic type to determine whether and how ischemia affects macular microstructure. METHODS This retrospective, nonrandomized study included 75 newly diagnosed RVO cases (group 1: 55 nonischemic RVO cases and group 2: 20 ischemic RVO cases) with evidence of center-involving ME without any treatment. Quantitative measures on spectral-domain optical coherence tomography images were performed. Central subfield thickness (CST) was collected in the central 1 mm from the thickness map. The following items were evaluated in a 3-mm-wide area (perifoveal ETDRS circle) centered on the fovea: disorganization of the retinal inner layers (DRIL), disrupted external limiting membrane (ELM) and ellipsoid zone disruption (EZD). The microstructural changes were measured manually. RESULTS Baseline characteristics, such as age, sex, study eye, and RVO risk factors, were similar between the groups (P > 0.05). CST was 554.15 ± 191.45 µm for group 1 and 769.90 ± 290.00 µm for group 2 (P: 0.001). The extent of DRIL was 1864.09 ± 941.70 µm and 2447.25 ± 492.59 µm for groups 1 and 2, respectively (P: 0.010). The disrupted ELM length was 1700 (0-3000) µm for group 1 and 2725 (300-3000) µm for group 2 (P: 0.027). The EZD length was 1453.09 ± 870.38 µm for group 1 and 1846.00 ± 926.54 µm for group 2 (P: 0.093). CONCLUSIONS Ischemic RVOs cause greater macular edema and greater disruption in the macular microstructure compared to nonischemic RVOs, especially in terms of DRIL and ELM.

Abstract
PURPOSE To evaluate spectral-domain (SD)-OCT features associated with baseline vision and visual outcomes in the prospective, multicenter Study Evaluating Dosing Regimens for Treatment with Intravitreal Ranibizumab Injections in Subjects with Macular Edema following Retinal Vein Occlusion (SHORE). DESIGN Post hoc analysis of prospective clinical trial data. PARTICIPANTS Two hundred two participants in the 15-month, phase 4 SHORE study comparing monthly versus pro re nata ranibizumab after 7 monthly doses in eyes with retinal vein occlusion (RVO) with macular edema. METHODS Baseline SD-OCT images were assessed for (1) central subfield thickness (CST); (2) presence of vitreomacular adhesion, vitreomacular traction, or epiretinal membrane; (3) presence, location, and amount of intraretinal fluid or subretinal fluid (SRF); (4) presence, location, and amount of hyperreflective foci (HF); (5) disorganization of retinal inner layers (DRIL); and (6) disruption of external limiting membrane (ELM), ellipsoid zone (EZ), and interdigitation zone (IZ). Univariate and multivariate regression analyses were performed to evaluate the association of these features with baseline best-corrected visual acuity (BCVA) and change in BCVA after 7 monthly ranibizumab injections. MAIN OUTCOME MEASURES Association of SD-OCT features with baseline BCVA and change in BCVA after 7 monthly ranibizumab injections. RESULTS Before therapy, worse baseline BCVA was associated with ERM presence (P = 0.0045), thicker SRF (P = 0.0006), larger intraretinal cysts (P = 0.0015), and higher percentage of DRIL (P < 0.0001), percentage of ELM disruption (P < 0.0001), percentage of EZ disruption (P = 0.0003), and percentage of IZ disruption (P = 0.0018). In multivariate models, only percentage of ELM disruption independently impacted baseline BCVA (P < 0.0001). After 7 monthly ranibizumab injections, mean BCVA improved by 18.3±12.6 Early Treatment Diabetic Retinopathy Study letters in treated eyes. The only factors independently associated with BCVA gain after 7 monthly ranibizumab treatments were younger age (P < 0.0001) and worse baseline BCVA (P < 0.0001). CONCLUSIONS Although SD-OCT features may be associated with presenting vision in eyes with macular edema and RVO, most eyes treated with ranibizumab achieve substantial vision gains, and only older age and better baseline BCVA limited visual improvements.
