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
The current standard treatment of myopic choroidal neovascularisation (mCNV) is intravitreal injection of VEGF antagonists. This study was proposed to assess efficacy and safety of intravitreal bevacizumab (IVB) for the treatment of mCNV across a 10-year follow-up. Thirty eyes of thirty patients with treatment-naïve mCNV who underwent IVB and were followed up with for a minimum of ten years were recruited for the present retrospective cohort study. All participants were treated with three monthly IVB at baseline and then evaluated and treated under pro re nata (PRN) schedule. Outcome measures were to determine BCVA changes over years and identify the predictive factors of both final visual outcome and need for retreatment. Analysis of the main involved prognostic factors with correlations among variables is reported. Visual acuity remained stable at 10-year follow-up (p = 0.001) with the greatest improvement at 2 years (p < 0.0001) in all CNV locations. Baseline BCVA correlated positively with final BCVA (β = 0.88, p < 0.0001, R2: 0.75). No predictive factors for the need of additional injections were identified. Retinal and choroidal thickness significantly reduced over time but without correlation with the number of injections. CNV max height and area significantly decreased at 10 years (p < 0.0001 and p = 0.003, respectively), with complete regression of mCNV lesion in 40% of subjects. Intravitreal bevacizumab resulted as long-term effective and safe therapy for mCNV with sustained results at 10 years.

Abstract
PURPOSE To compare visual functional improvement and retinal structural changes of aflibercept versus ranibizumab for the management of treatment-naïve choroidal neovascularization related to pathological myopia. PATIENTS AND METHODS A prospective randomized study included patients suffering from myopic choroidal neovascularization. Patients received three intravitreal injections of aflibercept (2 mg) or ranibizumab (0.5 mg) in 1:1 ratio every 4 weeks. Ophthalmic evaluation and optical coherence tomography were performed at baseline, 1, 2, and 3 months after last injection. Primary outcome measure was the visual acuity change from baseline to month 3 after injection. Secondary outcome measures included change in retinal thickness and the relation of morphological and functional changes to baseline assessment parameters. RESULTS A total of 48 myopic patients (48 eyes) suffering from myopic choroidal neovascularization were randomly assigned to receive either aflibercept (Group A) or ranibizumab (Group B). In Group A, best-corrected visual acuity significantly improved from 0.53 ± 0.10 logMAR to 0.38 ± 0.11 logMAR, at 3 months, and from 0.55 ± 0.11 logMAR to 0.39 ± 0.12 logMAR in Group B. Whereas, retinal thickness reduced from 317.7 ± 53.6 µm to 164.5 ± 81.9 µm in Group A, and from 321.1 ± 98.8 µm at baseline to 178.9 ± 64.5 µm in Group B at month 3. Changes in best-corrected visual acuity and central macular thickness were statistically insignificant between the two groups at final visit. CONCLUSION Both aflibercept and ranibizumab provided a significant improvement in visual acuity and retinal thickness in patients with myopic choroidal neovascularization. Comparable functional and architectural results were achieved by both treatment modalities.

Abstract
Myopia is a highly frequent ocular disorder worldwide and pathologic myopia is the 4th most common cause of irreversible blindness in developed countries. Pathologic myopia is especially common in East Asian countries. Ocular alterations associated with pathologic myopia, especially those involving the macular area-defined as myopic maculopathy-are the leading causes of vision loss in patients with pathologic myopia. High myopia is defined as the presence of a highly negative refractive error (>-6 to -8 diopters) in the context of eye elongation (26-26.5 mm). Although the terms high myopia and pathologic myopia are often used interchangeably, they do not refer to the same eye disease. The two key factors driving the development of pathologic myopia are: 1) elongation of the axial length and 2) posterior staphyloma. The presence of posterior staphyloma, which is the most common finding in patients with pathologic myopia, is the key differentiating factor between high and pathologic myopia. The occurrence of staphyloma will, in most cases, eventually lead to other conditions such as atrophic, traction, or neovascular maculopathy. Posterior staphyloma is for instance, responsible for the differences between a myopic macular hole (MH)-with and without retinal detachment-and idiopathic MH. Posterior staphyloma typically induces retinal layer splitting, leading to foveoschisis in myopic MH, an important differentiating factor between myopic and emmetropic MH. Myopic maculopathy is a highly complex disease and current classification systems do not fully account for the numerous changes that occur in the macula of these patients. Therefore, a more comprehensive classification system is needed, for several important reasons. First, to more precisely define the disease stage to improve follow-up by enabling clinicians to more accurately monitor changes over time, which is essential given the progressive nature of this condition. Second, unification of the currently-available classification systems would establish standardized classification criteria that could be used to compare the findings from international multicentric studies. Finally, a more comprehensive classification system could help to improve our understanding of the genetic origins of this disease, which is clearly relevant given the interchangeable-but erroneous-use of the terms high and pathologic myopia in genetic research.

Abstract
PURPOSE To investigate the prevalence and incidence of myopic choroidal neovascularization (CNV) in Taiwan, including the health care utilization and treatment-associated costs. METHODS A retrospective cohort study using existing data from the Taiwanese National Health Insurance claims database to identify patients who had a diagnosis of myopic CNV recorded from 1 January 2009 to 31 December 2011. The prevalence of myopic CNV was monitored during this period, and the frequency and cost of both treatment visits and monitoring visits were analyzed for 2 years following diagnosis. RESULTS The prevalence of myopic CNV was 0.017%. In total, 9068 patients with myopic CNV were identified, 12.3% (n = 1111) of whom were treated. Of those treated, 72.0% (n = 800) received intravitreal anti-vascular endothelial growth factor injections (IVI); the remainder received either photodynamic therapy with verteporfin (vPDT), laser photocoagulation, or a combination of therapies. IVI was associated with the largest number of treatment visits as well as a higher administrative (non-drug) cost per treatment visit (a mean of USD 57.18). vPDT alone was associated with a higher overall cost per treatment visit and more monitoring visits than IVI or laser photocoagulation. Costs for monitoring visits were highest for IVI. CONCLUSIONS The prevalence of myopic CNV was lower than that reported in previous studies, possibly because of differences in age distribution in the populations studied. The frequencies of treatment administered were similar to those reported in previous studies; however, a cost-effectiveness comparison could not be made owing to lack of data in previous studies.

Abstract
Myopic choroidal neovascularization (mCNV) is the second most common form of CNV after age-related macular degeneration (AMD). It is a sight-threatening complication of pathologic myopia (PM) and often affects patients in their working years causing significant impact on quality of life. Previous therapies such as photodynamic therapy with verteporfin have shown limited success. Due to the similarities in pathogenesis of mCNV and AMD CNV, anti-vascular endothelial growth factor therapy (anti-VEGF), which has so far been the mainstay of treatment for AMD CNV, has been shown to be effective in the treatment of mCNV and has become the first-line treatment of choice. This article aims to examine briefly the epidemiology and pathophysiology of mCNV, as well as review the evidence for efficacy, safety, and clinical use of anti-VEGF treatment for mCNV.

Abstract
Spectral domain optical coherence tomography cross-sectional imaging of the macula has conventionally been resolved into four bands. However, some doubts were raised regarding authentication of the existence of these bands. Recently, a number of studies have suggested that the second band appeared to originate from the inner segment ellipsoids of the foveal cone photoreceptors, and therefore the previously called inner segment-outer segment junction is now referred to as inner segment ellipsoidband. Photoreceptor dysfunction may be a significant predictor of visual acuity in a spectrum of surgical and medical retinal diseases. This review aims to provide an overview and summarizes the role of the photoreceptor inner segment ellipsoid band in the management and prognostication of various vitreoretinal diseases.

Abstract
AIM To compare the best corrected visual acuity (BCVA) between Verteporfin with photodynamic therapy (PDT) and intravitreal anti-vascular endothelial growth factor (anti-VEGF) in patients with myopic choroidal neovascularization (CNV). METHOD Published literature from Medline, Premedline, Embase and the Cochrane Library from inception until November 2013 were retrieved. All studies evaluating the BCVA between Verteporfin with PDT and intravitreal anti-VEGF for myopic CNV were included. The results were pooled using mean difference (MD), a corresponding 95% confidence interval (CI). RESULTS Finally, five studies enrolled 349 eyes were included in the meta-analysis. We inferred that the BCVA of myopic CNV after the treatment of anti-VEGF was significantly better compared with Verteporfin with PDT (MD=0.25, 95%CI:0.17-0.33, Z=5.97, P<0.00001). CONCLUSION This meta-analysis suggests that intravitreal anti-VEGF could have a better BCVA after treatment than Verteporfin with PDT for myopic CNV.

Abstract
Myopic choroidal neovascularization (mCNV), one of the complications of pathological myopia, is also one of the leading causes of visual impairment worldwide. The socioeconomic impact of mCNV in Asian countries is particularly significant due to the rising incidence of pathological myopia. There have been major advances in the treatment of mCNV in the past few years. Previous treatment modalities, such as thermal laser photocoagulation and photodynamic therapy, aimed to prevent vision loss; however, newer modalities such as intravitreal anti-vascular endothelial growth factor (VEGF) agents have been shown to successfully restore vision in many patients. Challenges remain as long term safety and efficacy of anti-VEGF agents are unknown. This article aims to provide a review of the literature of the epidemiology, progression, clinical course and treatment modalities as well as areas of future developments related to myopic CNV.

Abstract
PURPOSE To evaluate the long-term efficacy of bevacizumab in the treatment of choroidal neovascularization (CNV) secondary to pathological myopia. METHODS In this retrospective single-center non-comparative study the medical records of 29 eyes from 29 patients with naïve CNV secondary to high myopia and at least 42 months of follow up were reviewed. All eyes received a loading dose of one intravitreal injection per month for two consecutive months and were retreated on an as-needed basis during the course of follow up. The main outcome measures were post-treatment ETDRS best-corrected visual acuity (BCVA) and visual stabilization over time. Stepwise linear regression analysis was performed to identify prognostic factors for visual acuity gain and final visual acuity outcome at 42 months. RESULTS At 42 months of follow-up bevacizumab was associated with the maintenance of significant benefits in visual acuity compared to baseline. No adverse ocular or systemic effects from treatment were encountered. No statistically significant correlations were found between BCVA change and any of the quantitative variables. However, when final BCVA was taken as a dependent variable and CNV size and pre-treatment VA were included as predictors, a bivariate model was identified by stepwise regression which gave a 75 % of explained variance. CONCLUSIONS Bevacizumab treatment was found to be efficacious in the treatment of myopic CNV, resulting in stable gains in visual acuity lasting at least 42 months, without any adverse ocular or general events. Myopic CNV size was identified as a significant prognostic factor.

Abstract
Choroidal neovascularisation (CNV) is a common vision-threatening complication of myopia and pathological myopia. Despite significant advances in understanding the epidemiology, pathogenesis and natural history of myopic CNV, there is no standard definition of myopic CNV and its relationship to axial length and other myopic degenerative changes. Several treatments are available to ophthalmologists, but with the advent of new therapies there is a need for further consensus and clinical management recommendations. Verteporfin photodynamic therapy has been an established treatment for subfoveal myopic CNV for many years, but this treatment does not restore visual acuity and is associated with long-term chorioretinal atrophy. More recently, clinical trials investigating the efficacy and safety of anti-vascular endothelial growth factor agents in patients with myopic CNV have demonstrated substantial visual acuity gains and quality of life increases compared with photodynamic therapy. These enhanced outcomes provide updated evidence-based clinical management guidelines of myopic CNV, and increase the need for a generally accepted definition for myopic CNV. This review critically summarises the latest myopic CNV literature in the context of clinical experience and recommends a myopic CNV treatment algorithm.

Abstract
Background To compare the long-term efficacy of ranibizumab versus bevacizumab for myopic choroidal neovascularization (CNV). Methods This was a retrospective, multicenter, comparative, non-randomized study of 64 consecutive patients with myopic CNV treated with ranibizumab (22 patients) or bevacizumab (42 patients). Best-corrected visual acuity (BCVA) and central foveal thickness (CFT) on optical coherence tomography were evaluated before and after treatment. All the patients were followed for at least 12 months. Results BCVA (logarithm of the minimal angle of resolution) improved from 0.63 ± 0.30 to 0.43 ± 0.27, 0.41 ± 0.37, 0.40 ± 0.39, 0.39 ± 0.43, and 0.39 ± 0.42 at 1, 2, 3, 6, and 12 months after treatment in the ranibizumab group, and from 0.67 ± 0.28 to 0.52 ± 0.31, 0.49 ± 0.31, 0.47 ± 0.31, 0.42 ± 0.32, and 0.46 ± 0.43 in the bevacizumab group (all P < 0.05 compared with baseline BCVA in each group). CFT decreased by 20.21%, 19.58%, and 22.43% from the baseline 304 ± 76 μm at 3, 6, and 12 months after treatment in the former group, and by 15.20%, 15.67%, and 15.56% from the baseline 297 ± 62 μm in the latter group (all P < 0.05 compared with baseline CFT in each group). BCVA improvement and CFT reduction did not statistically differ when compared at the same periods from treatment between 2 groups. Neither ocular nor systemic safety problems appeared during follow up. Conclusions This study showed a similar functional and anatomical improvement after treatment of ranibizumab and bevacizumab for myopic CNV over a 12-month follow-up period.

Abstract
AIM To evaluate the efficacy and safety of a combined treatment for myopic choroidal neovascularization (CNV) using photodynamic therapy (PDT) and intravitreal bevacizumab and to compare it with intravitreal bevacizumab monotherapy. METHODS Thirty-four eyes with angiographic evidence of myopic CNV were randomly divided into two groups: 17 were treated with one intravitreal bevacizumab injection (1.25 mg) and low-fluence-rate PDT within seven days of the injection (Group A). The other 17 received monotherapy with bevacizumab injections (Group B). Clinical evidence of complications, best corrected visual acuity (BCVA) and fluorescein leakage were evaluated. BCVA and optical coherence tomography (OCT) were evaluated monthly. The timepoints follow-up was established at 6 and 12mo. All patients were retreated following a PRN protocol. RESULTS A total of 34 eyes of 34 patients (26 women and 8 men) with a mean age of 62.35 years were included. In Group A (17 eyes) the mean BCVA increased from 0.55±0.13 logMAR before the treatment to 0.40±0.09 logMAR at the 12mo follow-up (P<0.01). In Group B (17 eyes) the mean BCVA increased from 0.60±0.11 logMAR before the treatment to 0.55±0.12 logMAR at the 12mo follow-up (P<0.01). There was no statistically significant difference between the two groups in terms of LogMar visual acuity. In Group A the mean number of combined treatments was 1.8±0.11 per patient; in Group B the mean number of intravitreal bevacizumab injections was 3.1±0.08 per patient. The number of treatments was significantly fewer in Group A (P<0.01). No local or systemic side effects occurred among any of the patients treated in this study. CONCLUSION The combination of anti-angiogenic injections and PDT appears to be a safe and effective option for myopic CNV treatment and allows for a significant reduction of intravitreal injections.

Abstract
Choroidal neovascularization (CNV) secondary to pathological myopia is an important cause of significant visual impairment in young adults. High myopia is particularly prevalent in Asian population. New scientific contributions have been made to the understanding of high myopia and myopic CNV. Treatment for myopic CNV has previously relied on photodynamic therapy, laser photocoagulation, and submacular surgery. The treatment outcomes from these modalities are, however, controversial. The introduction of antiangiogenic agents including bevacizumab and ranibizumab has brought the treatment of myopic CNV into a new era. The purpose of this review was to provide an overview of the natural history of myopic CNV, the prognostic factors, and the various treatment options including laser photocoagulation and photodynamic therapy, with particular attention on antiangiogenic agents.

Abstract
PURPOSES To update existing evidence and evaluate intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections for myopic choroidal neovascularization. METHODS The authors conducted comprehensive search in PubMed, EMBASE, Cochrane Library, Biosis Preview, and LILACS. Included studies were categorized by study design. Comparative studies were classified as randomized controlled trials (RCTs) and non-RCT studies, and these two types of studies were presented and meta-analyzed separately for the following comparisons: 1) anti-VEGF versus photodynamic therapy, 2) anti-VEGF monotherapy versus combination therapy with photodynamic therapy, 3) single versus 3 monthly injections followed by pro re nata (PRN) treatment, and 4) ranibizumab versus bevacizumab. Noncomparative prospective series were pooled to estimate mean visual gain, mean retinal thickness change, and the average number of anti-VEGF injections required for myopic choroidal neovascularization. Ocular and systemic adverse events were also summarized. RESULTS Literature search yielded 18 comparative studies and 83 noncomparative studies. Superiority of anti-VEGF over photodynamic therapy in a 24-month period was confirmed by 2 RCTs and 6 non-RCT studies. The influence of combined photodynamic therapy was uncertain based on two non-RCT studies. Three non-RCT studies showed that the visual outcomes of 3+PRN injections might be slightly better than 1+PRN injections within 1 year. No difference was observed between ranibizumab and bevacizumab in two RCTs and one non-RCT study. The estimated visual improvement was two lines on average. Adverse events were uncommon as reported. CONCLUSION Accumulating evidence confirmed that anti-VEGF injections should be the first-line therapy for myopic choroidal neovascularization.

Abstract
OBJECTIVE To compare the efficacy and safety of ranibizumab 0.5 mg, guided by visual acuity (VA) stabilization or disease activity criteria, versus verteporfin photodynamic therapy (vPDT) in patients with visual impairment due to myopic choroidal neovascularization (CNV). DESIGN Phase III, 12-month, randomized, double-masked, multicenter, active-controlled study. PARTICIPANTS Patients (N = 277) with visual impairment due to myopic CNV. METHODS Patients were randomized to receive ranibizumab on day 1, month 1, and thereafter as needed guided by VA stabilization criteria (group I, n = 106); ranibizumab on day 1 and thereafter as needed guided by disease activity criteria (group II, n=116); or vPDT on day 1 and disease activity treated with ranibizumab or vPDT at investigators' discretion from month 3 (group III, n = 55). MAIN OUTCOME MEASURES Mean average best-corrected visual acuity (BCVA) change from baseline to month 1 through months 3 (primary) and 6, mean BCVA change and safety over 12 months. RESULTS Ranibizumab treatment in groups I and II was superior to vPDT based on mean average BCVA change from baseline to month 1 through month 3 (group I: +10.5, group II: +10.6 vs. group III: +2.2 Early Treatment Diabetic Retinopathy Study [ETDRS] letters; both P<0.0001). Ranibizumab treatment guided by disease activity was noninferior to VA stabilization-guided retreatment based on mean average BCVA change from baseline to month 1 through month 6 (group II: +11.7 vs. group I: +11.9 ETDRS letters; P<0.00001). Mean BCVA change from baseline to month 12 was +13.8 (group I), +14.4 (group II), and +9.3 ETDRS letters (group III). At month 12, 63.8% to 65.7% of patients showed resolution of myopic CNV leakage. Patients received a median of 4.0 (group I) and 2.0 (groups II and III) ranibizumab injections over 12 months. No deaths or cases of endophthalmitis and myocardial infarction occurred. CONCLUSIONS Ranibizumab treatment, irrespective of retreatment criteria, provided superior BCVA gains versus vPDT up to month 3. Ranibizumab treatment guided by disease activity criteria was noninferior to VA stabilization criteria up to month 6. Over 12 months, individualized ranibizumab treatment was effective in improving and sustaining BCVA and was generally well tolerated in patients with myopic CNV.

Abstract
AIM To evaluate the visual outcomes of choroidal neovascularization (CNV) secondary to pathological myopia and the impact of novel risk factors affecting the final visual outcome. METHODS Interventional case series of 18 consecutive patients with pathological myopia treated with photodynamic therapy (PDT). Inclusion criteria were spherical equivalent -6D or worse or features of pathological myopia on retinal examination. The main outcome measure was final best-corrected visual acuity (BCVA). RESULTS Of 18 eyes, 13 (72.2%) avoided moderate visual loss (≥3 lines of LogMAR BCVA) and 5 eyes (27.8%) improved by at least 1 line after 1 year. Patients with LogMAR BCVA ≤0.3 (Snellen equivalent 20/40) at one year were younger than those with BCVA >0.3 (mean age 39.0 vs 61.6 years, P=0.001). A higher proportion of eyes with greatest linear dimension (GLD) of ≤1000µm avoided moderate visual loss (100% vs 50%, P=0.026). Among patients who were treated within 2 weeks of visual symptoms, 88.9% avoided the loss of 3 or more lines compared to 55.6% for those who presented later. The mean improvement in LogMAR BCVA of those with GLD ≤1000µm was +0.12 compared to a loss of 0.55 LogMAR units for those with GLD >1000µm (P=0.02). Visual outcomes were not associated with gender or refractive error. CONCLUSION Good visual outcome in myopic CNV is associated with younger age, smaller lesion size and earlier initiation of treatment. These factors are relevant for ophthalmologists considering treatment options for myopic CNV.

Abstract
PURPOSE To compare visual outcomes after intravitreal anti-vascular endothelial growth factor (VEGF) injection or photodynamic therapy (PDT) for idiopathic choroidal neovascularization (CNV). DESIGN Retrospective study. METHODS Among 29 eyes (28 patients), 15 eyes (15 patients) received anti-VEGF therapy and 14 eyes (13 patients) received PDT. Best-corrected visual acuity (BCVA, logMAR [logarithm of minimal angle of resolution]) at baseline and 1, 3, 6, 12, and 24 months after initial treatment were compared. The eyes were classified by BCVA changes: improved (improvement ≥0.3 logMAR), decreased (deterioration ≥0.3 logMAR), and stable. RESULTS Mean BCVA was 0.56 ± 0.38 logMAR (20/72 in Snellen equivalent) in the PDT group and 0.44 ± 0.59 logMAR (20/55 in Snellen equivalent) in the anti-VEGF group at baseline (P = .104, Mann-Whitney U test). The anti-VEGF group showed significantly better mean BCVA at each follow-up visit when compared with that of PDT (P = .004 at 1 month, P = .002 at 3 months, P = .037 at 6 months, P = .031 at 12 months, and P = .049 at 24 months; Mann-Whitney U test, respectively). When compared with the baseline, mean BCVA at each follow-up visit was better in the anti-VEGF group (P = .196 at 1 month, P = .007 at 3 months, P = .046 at 6 months, P = .046 at 12 months, and P = .049 at 24 months; Wilcoxon signed rank test, respectively), whereas BCVA in the PDT group was not. At 24 months, all eyes (100.0%) treated with anti-VEGF showed stable or improved BCVA, whereas 3 eyes (21.3%) showed visual deterioration after PDT. CONCLUSIONS Anti-VEGF therapy was superior to PDT for idiopathic CNV, and superior efficacy was sustained until 24 months.

Abstract
Background The aim of this study was to evaluate the efficacy of intravitreal bevacizumab when administered on an as-needed basis for the treatment of myopic choroidal neovascularization (CNV), and to assess visual changes upon treatment. Methods This study was designed as a retrospective, interventional case series, for which the inclusion criteria were pathologic myopia, and documentation of untreated active macular CNV on fluorescein angiography and optical coherence tomography. Monthly changes in best-corrected visual acuity (BCVA), visual gain after each treatment, and correlation with refraction, age, location, and dimension of CNV were considered. The data were analyzed using the one-tailed, paired Wilcoxon test. Results Nineteen naive eyes were found suitable for the study. The mean number of treatments was 3.32 ± 2.36 (confidence interval 2.25–4.37) during a mean follow-up period of 18.95 ± 8.3 months. At baseline, mean BCVA was 0.58 ± 0.37 logarithm of the minimum angle of resolution (logMAR) units. At 12 months, mean BCVA was 0.39 ± 0.35 logMAR and at 24 months was 0.39 ± 0.40. Mean improvement in BCVA from baseline was +0.17 ± 0.25 logMAR (P < 0.05) at month 12, +0.14 ± 0.25 logMAR (P = 0.1) at month 18, and +0.09 ± 0.32 logMAR (P = 0.5) at month 24. Improvement on pretreatment BCVA was significant (+0.16 logMAR, P < 0.01) after the first injection, but not after the second (−0.01 logMAR, P = 0.5) or third (+0.02 logMAR, P = 0.5) injections. There was a statistically significant correlation between age and number of treatments, and between improvement in BCVA of foveal versus extrafoveal location of CNV. Conclusion The use of intravitreal bevacizumab “as needed” is an effective treatment for myopic CNV, but visual gain is statistically significant only after the first injection and decreases in the second year.

Abstract
AIM This systematic review assesses the prognostic factors for intravitreal bevacizumab injection (IVB) in the treatment of choroidal neovascularization (CNV) due to pathological myopia. METHODS The literature searches were performed in Ovid Medline, EMBASE and CENTRAL. Relevant studies with prognostic data on best corrected vision acuity (BCVA) after intravitreal bevacizumab injection were included for review. Two reviewers participated in the data retrieval and independently assessed each included study. RESULTS A total 252 articles were retrieved, including 16 studies containing the most updated and complete data on prognostic factors for neovascularization due to pathological myopia treated by intravitreal bevacizumab injection. A great number of quantitative, clinical, and treatment-related factors were determined to have a positive influence on vision outcome after intravitreal bevacizumab. CONCLUSION A lower rate of development of chorioretinal atrophy, smaller pretreatment CNV size, and younger age were indentified as the most consistently significant prognostic factors affecting the efficacy of IVB in eyes of myopic CNV and were associated with improved BCVA. A worse BCVA after IVB in eyes with myopic CNV probably was associated with subfoveal CNV, lower baseline BCVA, longer duration of CNV, incomplete regression of CNV, subretinal hemorrhage, and previous PDT treatment. No apparent association were observed between the refraction error, axial length, lens status and change in BCVA after IVB. We indentified significant prognostic factors in this systematic review study that might allow for the selection of patients with myopic CNV which are most likely to benefit from IVB.

Abstract
Recently published studies have shown that myopic choroidal neovascularization (mCNV) is efficiently treated by anti-vascular endothelial growth factor (VEGF) drugs. Within a prospective executive study, photodynamic therapy failed to prove a significant difference over the duration of 2 years. Although a systematic evaluation of different retreatment algorithms still has to be done the administration of single injections depending on specialist assessment of morphological changes, predominantly spectral domain optical coherence tomography (SD-OCT) and fundus, has achieved a marked visual improvement. The experience of treating age-related macular degeneration should not be simply transferred to mCNV and an individual approach, not only for female patients of childbearing age, is necessary.

Abstract
PURPOSE To evaluate the long-term efficacy of intravitreal anti-vascular endothelial growth factor (anti-VEGF) therapy as primary treatment for subfoveal myopic choroidal neovascularization (CNV). METHODS In all, 37 treatment-naïve eyes of 37 patients with subfoveal myopic CNV who received intravitreal bevacizumab (n=22) or ranibizumab (n=15) injections with at least 2 years of follow-up were reviewed. All eyes received initial three loading doses of anti-VEGF at monthly intervals and retreatment was performed in persistent or recurrent CNV. Multivariate regression analyses were performed to determine the prognostic factors for visual outcome. RESULTS The mean age was 57.3 years and the mean refractive error was -11.7 D. For all eyes, the mean logMAR best-corrected visual acuity improved from 0.86 (20/145) at baseline to 0.48 (20/60) at 2 years (P<0.001). The mean visual improvement for the bevacizumab and ranibizumab groups at 2 years was 2.8 and 5.1 lines, respectively (P=0.073). There was no significant difference in the proportion of eyes having visual gain of three or more lines or visual loss of three or more lines between the two groups. The mean number of injections was 3.8 for both bevacizumab and ranibizumab groups. Multivariate analyses showed that eyes with higher myopic refractive error were less likely to have visual gain after treatment (P=0.043), while size of CNV was negatively correlated with mean change in vision (P=0.046). CONCLUSIONS Intravitreal anti-VEGF therapy resulted in long-term visual improvement in myopic CNV. The treatment efficacy in terms of visual gain and number of retreatment appeared to be similar between bevacizumab and ranibizumab.

Abstract
PURPOSE To determine the 2-year results of intravitreal bevacizumab in highly myopic eyes with choroidal neovascularization (CNV). METHODS An open-label, consecutive, interventional case series. Seventy-five eyes of 69 consecutive Japanese patients with either subfoveal or nonsubfoveal myopic CNVs were studied. The eyes were treated with intravitreal bevacizumab and followed-up for at least 2 years. The best-corrected visual acuities at the baseline in eyes with subfoveal CNV were compared with that in eyes with nonsubfoveal CNV at 2 years after the intravitreal bevacizumab. RESULTS The difference between the mean best-corrected visual acuity at the baseline and that at 2 years in eyes with a subfoveal CNV was not significant. However, the mean best-corrected visual acuity in eyes with nonsubfoveal CNV was significantly improved from 0.53 ± 0.36 logarithm of the minimal angle of resolution units (Snellen 20/66) before intravitreal bevacizumab to 0.29 ± 0.36 logMAR units (Snellen 20/40) (P < 0.001) 2 years after intravitreal bevacizumab. The incidence of chorioretinal atrophy after 2 years was 3 of 49 (6.1%) in eyes with nonsubfoveal CNV and 21 of 26 (80.8%) in eyes with which subfoveal CNV (P < 0.001). Furthermore, the chorioretinal atrophy area with nonsubfoveal CNV was 0.05 ± 0.21 mm, which was also significantly smaller than that of subfoveal CNV at 1.76 ± 1.60 mm (P < 0.001). CONCLUSION Intravitreal bevacizumab is a good treatment for eyes with nonsubfoveal CNV; however, another treatment is necessary for eyes with a subfoveally located CNV.

Abstract
Myopic choroidal neovascularization (CNV) is one of the leading causes of visual impairment worldwide. The clinical and socioeconomic impact of myopic CNV in Asian countries is particularly significant due to rising trend in the prevalence and severity of pathological myopia. The exact pathogenesis of myopic CNV remains unclear and there is paucity of information with respect to incidence and risk factors for myopic CNV from prospective studies. Furthermore, there are no recognized measures that may prevent or delay the development of CNV in eyes with pathological myopia. Advances have been made in the diagnosis and characterization of myopic CNV over the years. Until recently, treatment modalities for myopic CNV were limited to thermal laser photocoagulation and photodynamic therapy with verteporfin, both these modalities primarily aim at prevention of further visual loss. In the last 5 years, inhibitors of vascular endothelial growth factor (VEGF) have been used successfully and may improve vision to some extent. Nevertheless, the long-term safety and efficacy of anti-VEGF agents remains unknown. Furthermore, the risk of developing chorioretinal atrophy remains the key factor in determining the final visual outcome. This review article summarizes the current literature on myopic CNV, highlighting new evolving diagnostic and treatment modalities, prognostic factors influencing visual outcome, and areas of future research.

Abstract
Myopic choroidal neovascularization (CNV) is a vision-threatening complication in the eyes with pathological myopia, which is particularly prevalent among young and middle-aged Asians globally. To date, the verteporfin in photodynamic therapy study is the only randomized-controlled study in treatment of subfoveal myopic CNV. However, its long-term benefit is controversial. Recently, intravitreal injections of anti-vascular endothelial growth factors have shown promising results. In the absence of randomized-controlled trial comparing the efficacy of anti-vascular endothelial growth factors with photodynamic therapy and placebo, the purpose of this article is to review the current studies on functional and anatomical outcomes in both subfoveal and juxtafoveal myopic CNV. Furthermore, the influences of various doses and frequencies, as well as age and previous photodynamic therapy treatment on its effect are described.

Abstract
PURPOSE To evaluate the effects of intravitreal bevacizumab in the treatment of subfoveal choroidal neovascularization (CNV) related to pathological myopia. METHODS Thirty eyes with treatment-naive CNV were included. Best-corrected visual acuity on Early Treatment Diabetic Retinopathy Study chart, optical coherence tomography (OCT), and fluorescein angiography assessment was performed at baseline and thereafter monthly for more than 24 months. Intravitreal bevacizumab on an as-per-needed basis was administered if either persistent intraretinal/subretinal fluid was detected on OCT or the presence of leakage was noted on fluorescein angiography. Primary outcome measures included the change in mean best-corrected visual acuity and the proportion of eyes improving by three lines or greater. Secondary outcome measures included the change in mean central macular thickness on OCT. The proportion of eyes with resolution of intraretinal/subretinal fluid on OCT and leakage on fluorescein angiography over the follow-up was also noted. RESULTS Mean best-corrected visual acuity improved from 54.8 ± 14.8 (Early Treatment Diabetic Retinopathy Study letters ± SD) to 59.03 ± 17.0 at 3 months, subsequently stabilizing to 58.63 ± 18.52 at 12 months and 59.25 ± 20 at 24 months. A statistically significant difference was detected only at the 1-month examination. Best-corrected visual acuity at 24 months showed a 3-line improvement in 36.6% of cases and at least a 1-line increment in 43.3% of cases. Mean central macular thickness showed no significant reduction from baseline (216.8 ± 86 µm) up to the end of 24 months (205 ± 77.8 µm). At the last visit, a complete CNV closure was obtained in 93% of cases while intraretinal/subretinal fluid was detected on OCT in 13% of cases. The mean number of intravitreal bevacizumab injections was 4.73 (range, 1-10) at the end of 12 months and 5.9 (range, 1-13) at the end of the 24 months. CONCLUSION Intravitreal bevacizumab injection for myopic subfoveal CNV administered on an as-per-needed basis over 24 months of follow-up achieved stabilization of vision with >90% CNV closure rate.

Abstract
PURPOSE To report the anatomical and functional outcomes of intravitreal bevacizumab in both young and old Chinese patients with myopic choroidal neovascularization. METHODS Consecutive series of 56 eyes (52 patients) with myopic choroidal neovascularization treated exclusively with intravitreal bevacizumab were reviewed retrospectively. Data from clinical examination, fundus photography, fluorescein angiography, and optical coherence tomography were collected. RESULTS Vision significantly improved after intravitreal bevacizumab in this patient series (P < 0.0001), with an average of 2.2 injections. Higher myopia was positively correlated to a worse outcome (r = -0.3, P = 0.036). Stratifying by age, the correlation between spherical equivalent and final outcome showed statistical significance (r = -0.44, P = 0.027) only in younger patients. In younger patients, both spherical equivalent (P = 0.036) and initial visual acuity (P = 0.004) were predictive factors for visual outcome after adjusting for age, spherical equivalent, and number of injections, whereas in older patients, only initial visual acuity (P < 0.0001) was predictive of visual outcome after similar adjustments. CONCLUSION Younger patients do not have a better outcome when compared with older patients. Initial visual acuity, regardless of age, plays a more significant role. Both initial visual acuity and spherical equivalent are predictive factors for final visual acuity in young Chinese patients.

Abstract
Purpose To present and document the effectiveness of intravitreal ranibizumab in the treatment of patients with choroidal neovascularization due to butterfly-shaped pattern dystrophy (PD) of the macula. Methods Three intravitreal ranibizumab injections of 0.5 mg/0.05 ml in monthly intervals were given to a patient with a previously diagnosed butterfly-shaped PD who subsequently developed subfoveal choroidal neovascularization on the right eye. The patient had previously received a combination of verteporfin/photodynamic therapy for a juxtafoveal choroidal neovascular membrane on the left eye. Results At the end of the treatment course, there was significant improvement of the patient's vision and the appearance of the macula on optic coherence tomography and fluorescein angiography. Best-corrected visual acuity improved from 6/12 to 6/6 and retinal thickness at the macula decreased from 323 to 247 μm. No subretinal fluid remained. The patient is clinically stable over a 12-month follow-up period. Conclusions Intravitreal ranibizumab seems to be an effective and safe option for the treatment of subfoveal choroidal neovascularization in patients with butterfly-shaped PD.

Abstract
In Western countries, therapeutic management of patients affected by choroidal neovascularization (CNV) secondary to different typologies of macular degeneration represents a major health care problem. Age-related macular degeneration is the disease most frequently associated with CNV development. Schematically, CNVs can be distinguished into classic and occult subtypes, which are characterized by variable natural history and different responsiveness to some therapeutic procedures. At present, the dramatic vision loss due to CNV can be mainly treated by two interventional strategies, which are utilizable in either single or combined modalities: photodynamic therapy with verteporfin (PDT-V), and intravitreal administration of drugs acting against vascular endothelial growth factor. The combined use of PDT-V and anti-angiogenic drugs represents one of the most promising strategies against neovascular macular degeneration, but it unavoidably results in an expensive increase in health resource utilization. However, the positive data from several studies serve as a basis for reconsidering the role of PDT-V, which has undergone a renaissance prompted by the need for a more rational therapeutic approach toward CNV. New pharmacogenetic knowledge of PDT-V points to exploratory prospects to optimize the clinical application of this intriguing photothrombotic procedure. In fact, a Medline search provides data regarding the role of several single nucleotide polymorphisms (SNPs) as genetic predictors of CNV responsiveness to PDT-V. Specifically, correlations between SNPs and different levels of PDT-V efficacy have been detected by examining the gene variants influencing (i) thrombo-coagulative pathways, i.e. methylenetetrahydrofolate reductase (MTHFR) 677C>T (rs1801133), factor V (F5) 1691G>A (rs6025), prothrombin (F2) 20210G>A (rs1799963), and factor XIII-A (F13A1) 185G>T (rs5985); (ii) complement activation and/or inflammatory processes, i.e. complement factor H (CFH) 1277T>C (rs1061170), high-temperature requirement factor A1 (HTRA1) promoter -512G>A (rs11200638), and two variants of the C-reactive protein (CRP) gene (rs2808635 and rs876538); and (iii) production and bioavailability of vascular endothelial growth factor (VEGFA -2578C>A [rs699947] and rs2146323). This article critically evaluates both the clinical plausibility and the opportunity to utilize the most important SNP-response interactions of PDT-V for an effective upgrade of the current anti-CNV therapeutic scenario. In addition, the pharmacogenetics of a very severe post-PDT-V adverse event, i.e. a decrease in acute vision, is briefly discussed. A comprehensive appraisal of the findings reviewed in this article should be carefully considered to design future trials aimed at verifying (after proper genotypic stratification of the enrolled patients) whether these innovative pharmacogenetic approaches will be able to improve the multifaceted interventional management of neovascular macular degeneration.
