Abstract
PURPOSE To study the natural course of staphyloma-induced serous maculopathy (SISM) and the effects of treatments. DESIGN Retrospective case series. PARTICIPANTS This retrospective analysis included 26 eyes of 20 patients with SISM and at least 12 months of follow-up. METHODS Medical records were reviewed for patient demographics, such as age, sex, spherical equivalent, best-corrected visual acuity (BCVA), type of staphyloma, and imaging characteristics. Spectralis OCT B-scans were evaluated for the presence and height of the serous retinal detachment (SRD) at each follow-up visit. An SRD episode was defined as a period with SRD in 1 patient. MAIN OUTCOME MEASURES Changes in SRD height and BCVA. RESULTS Twenty-six eyes of 20 patients (70% female) were included. The mean age was 54 ± 11 years, and the mean spherical equivalent was -4.8 ± 3.3 diopters at baseline. The staphyloma was located inferior in 12 eyes (46%), inferonasal in 7 eyes (27%), and nasal in 7 eyes (27%). The mean follow-up duration was 73 ± 34 months. During follow-up, the SRD height fluctuated in all eyes, with a mean change of 125 ± 56 μm. The SRD disappeared completely during follow-up in 13 eyes (50%) and then reappeared in 7 eyes (35%). Resolution occurred spontaneous in 8 eyes (31%). The median time of an SRD episode was 25 (interquartile range 14-57) months. Treatment was performed in 20 eyes (77%) and led to resolution of SRD in 3 of the 15 photodynamic therapy treatments (21%), 2 of 5 (40%) anti-VEGF series, and 2 of 4 eyes (50%) treated with topical prednisolone. Best-corrected visual acuity at the final visit (0.42 ± 0.25) was not significantly different from BCVA at baseline (0.34 ± 0.27 logarithm of the minimum angle of resolution, P = 0.07), nor was BCVA change significantly different between treated eyes (n = 19) and nontreated eyes (n = 7, P = 0.3). CONCLUSION Serous retinal detachment in patients with SISM fluctuated over time and resolved without treatment in 31% of the eyes. Because treatment does not change the course of BCVA, a wait-and-see policy is advocated in these patients on the exclusion of treatable causes of SRD.

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.

Ten-Year Outcomes of Intravitreal Bevacizumab for Myopic Choroidal Neovascularization: Analysis of Prognostic Factors. Pharmaceuticals (Basel) 2021; 14:ph14101042. [PMID: 34681267 PMCID: PMC8541117 DOI: 10.3390/ph14101042] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2021] [Revised: 10/07/2021] [Accepted: 10/09/2021] [Indexed: 11/16/2022] Open
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.

Prog Retin Eye Res 2019; 69:80-115. [PMID: 30391362 DOI: 10.1016/j.preteyeres.2018.10.005] [Citation(s) in RCA: 208] [Impact Index Per Article: 41.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2018] [Revised: 10/18/2018] [Accepted: 10/22/2018] [Indexed: 02/09/2023]
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
BACKGROUND/PURPOSE This study aims to evaluate the clinical characteristics and visual outcome of macular hemorrhage in pathological myopia with or without choroidal neovascularization. METHODS We conducted a retrospective study of 55 patients with macular coin hemorrhage who were followed for at least 3 months from January 1997 to December 2013 at Shin Kong Wu Ho-Su Memorial Hospital (Taipei, Taiwan). All patients were evaluated using fluorescein angiography and optical coherence tomography for the detection of choroidal neovascularization (CNV). We also recorded clinical characteristics such as age, sex, refractory error, and myopic fundus, to determine the relationship between CNV and non-CNV associated macular hemorrhage. RESULTS A total of 55 patients (30 females, 54.55%) were reviewed. The mean age was 39.7 years old. The CNV group was found to be significantly older than the non-CNV group (p < 0.05), and there was no significant difference between sex, visual acuity myopic severity, and the prevalence of fundus findings between CNV and non-CNV groups. Twenty one patients (38.18%) were found to have CNV and were all treated with intravitreal antivascular endothelial growth factor (VEGF). The other 34 patients without CNV were not treated. In both groups, the visual acuity significantly improved (anti-VEGF treated, CNV associated group, 0.7 to 0.39, p = 0.002, and untreated, non-CNV associated group, 0.56 to 0.34, p = 0.0018, respectively). CONCLUSION Age significantly correlated to the CNV formation in high myopia with macular hemorrhage. Favorable visual outcomes were found in pathological myopic macular hemorrhage either in the anti-VEGF treated, CNV associated group or in the untreated, non-CNV associated group.

Abstract
PURPOSE To assess whether optical coherence tomography angiography (OCTA) can be used as an alternative to conventional fundus fluorescein angiography (FFA) for the detection of myopic choroidal neovascularization (CNV). DESIGN Validity and reliability analysis. METHODS Twenty-eight eyes of 26 consecutive Japanese patients with exudative lesions associated with pathologic myopia were included in this institutional study. Myopic CNV was detected in 23 eyes of 22 patients; 5 eyes exhibited simple hemorrhage. The main outcome measure was CNV detection by OCTA and FFA. The CNV area was individually measured by FFA and OCTA. Intraclass correlation coefficients (ICCs) for the CNV area, independently measured by 2 investigators using OCTA and FFA, were determined. RESULTS OCTA images with sufficient quality for CNV assessment were obtained for 17 eyes with CNV and 4 without. FFA alone detected CNV in all 17 eyes, while OCTA alone detected CNV in 16 (94.1%). The 1 eye for which CNV was not detected by OCTA exhibited a 0.01 mm(2) area on FFA. Both FFA and OCTA did not detect CNV in eyes with simple hemorrhage. The mean CNV areas on FFA and OCTA were 0.59 ± 0.56 mm(2) and 0.51 ± 0.55 mm(2), respectively; the 2 values were significantly correlated (P < .001, r = .86). The ICC (2, 1) values for FFA and OCTA were 0.944 and 0.997, respectively. CONCLUSIONS Our results indicate that OCTA can detect most myopic CNVs if high-quality images are acquired and can preclude the requirement for FFA in these settings.

Abstract
The aim of the present study was to evaluate the clinical efficacy and safety of intravitreal ranibizumab injections for the treatment of macular choroidal neovascularization (CNV) caused by pathological myopia. Between one and four intravitreal injections of ranibizumab were administered to 61 eyes from 61 patients who were diagnosed with macular CNV caused by pathological myopia. Following injection, the best-corrected visual acuity (BCVA), central macular thickness (CMT) and fundus fluorescein angiography (FFA) findings were evaluated monthly for a period of 6 months. Among the 61 eyes, 10 eyes received one injection, 44 received two injections, six received three injections and one received four injections (average, 1.97 injections). The BCVA was 0.02±0.01 prior to treatment and 0.30±0.03 subsequent to treatment, and this difference was statistically significant (P<0.01). The CMT was reduced by an average of 45.1 µm. Regarding the FFA results, 56 eyes had no CNV fluorescence leakage and five eyes had CNV fluorescence leakage following treatment; however, the intensity of CNV fluorescence leakage in the five eyes following treatment was lower than that prior to treatment. As a treatment for pathological myopia-induced macular CNV, intravitreal injections of ranibizumab may improve eyesight as well as the macular retinal tissue structure; thus, this is a safe and effective treatment method.

Abstract
Choroidal neovascularization (CNV) secondary to pathologic myopia has a very high incidence in global, especially in Asian, populations. It is a common cause of irreversible central vision loss, and severely affects the quality of life in the patients with pathologic myopia. The traditional therapeutic modalities for CNV secondary to pathologic myopia include thermal laser photocoagulation, surgical management, transpupillary thermotherapy, and photodynamic therapy with verteporfin. However, the long-term outcomes of these modalities are disappointing. Recently, intravitreal administration of anti-VEGF biological agents, including bevacizumab, ranibizumab, pegaptanib, aflibercept, and conbercept, has demonstrated promising outcomes for this ocular disease. The anti-VEGF regimens are more effective on improving visual acuity, reducing central fundus thickness and central retina thickness than the traditional modalities. These anti-VEGF agents thus hold the potential to become the first-line medicine for treatment of CNV secondary to pathologic myopia. This review follows the trend of “from bench to bedside”, initially discussing the pathogenesis of myopic CNV, delineating the molecular structures and mechanisms of action of the currently available anti-VEGF drugs, and then systematically comparing the up to date clinical applications as well as the efficacy and safety of the anti-VEGF drugs to the CNV secondary to pathologic myopia.

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.

Forty-two-month outcome of intravitreal bevacizumab in myopic choroidal neovascularization. Graefes Arch Clin Exp Ophthalmol 2014; 253:511-7.

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
AIM To evaluate the agreement between fluorescein angiography (FA) and spectral-domain optical coherence tomography (SD-OCT) in detecting myopic choroidal neovascularization (CNV) activity during bevacizumab treatment. METHODS Thirty-four patients with subfoveal myopic CNV were prospectively enrolled. FA and SD-OCT were performed at baseline and at all planned monthly visits. After the first injection, additional treatments were administered following detection of fluid on SD-OCT and/or leakage on FA. κ-Analysis was performed to examine the agreement between FA and SD-OCT. RESULTS At baseline, FA and SD-OCT agreed in 26/34 cases (κ=0.23); sensitivity and specificity were 77.4 and 66.7%, respectively. Seven eyes presented leakage on FA with no fluid on SD-OCT, 1 case showed intraretinal fluid on SD-OCT and no leakage on FA. At the 1-month examination, specificity and κ-value improved, and 30/34 cases showed complete concordance. At the 3- and 4-month examinations, a discordance was noted in 6 cases. From the 5-month examination on, a correspondence was achieved in at least 30/34 cases and reached a perfect match in 11 sessions. CONCLUSIONS Our study confirms the key role of FA in diagnosing myopic CNV. It seems possible there may be a role for SD-OCT in assisting FA to monitor the myopic CNV activity during anti-vascular endothelial growth factor antibody treatment.

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.

[PMID: 24075429 DOI: 10.1016/j.ajo.2013.08.002] [Citation(s) in RCA: 48] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2013] [Revised: 07/31/2013] [Accepted: 08/01/2013] [Indexed: 01/11/2023]
Abstract
PURPOSE To determine the efficacy of 1 intravitreal bevacizumab injection followed by pro re nata (1 + PRN) injection in cases of subfoveal myopic choroidal neovascularization (CNV) and to identify CNV-recurrence-related prognostic factors. DESIGN Retrospective observational case series. METHODS In total, 103 eyes of 89 consecutive naive patients who had subfoveal myopic CNV and had been followed-up for at least 2 years were included. Of those eyes, 24 had recurrences. The remaining eyes were stable after the initial treatment. RESULTS The average patient age was 51.1 ± 15.2 years. The average follow-up duration was 44.1 ± 12.7 months. At baseline and at the 1-year, 2-year, and final visits, the average best corrected visual acuities (BCVAs) were 0.57 ± 0.45, 0.38 ± 0.51, 0.40 ± 0.52, and 0.41 ± 0.41 logMAR, respectively. The recurrence rate during follow-up was 23.3%. The BCVA improved by 0.2 logMAR after 2.7 injections in the eyes without recurrence but by only 0.08 logMAR after 6.9 injections in the eyes with recurrence. In univariate analysis, recurrence was associated with older age, more myopic refraction, thinner choroid, larger CNV lesions, and subfoveal hemorrhage at baseline. In multivariate analysis, only baseline CNV lesion size associated significantly with CNV recurrence (P = 0.002). Recurrence, baseline BCVA, choroidal thickness, and CNV size associated significantly with final BCVA (P = 0.026, <0.0001, 0.007, and 0.002, respectively). Baseline choroidal thickness, CNV size, age, and presence of lacquer cracks associated significantly with injection number (P < 0.0001, <0.0001, 0.026, and 0.035, respectively). CONCLUSIONS 1 + PRN intravitreal bevacizumab monotherapy effectively stabilized subfoveal myopic CNV. The CNV size, the baseline BCVA, and the choroidal thickness were the main prognostic factors of subfoveal myopic CNV after 1 + PRN injection of bevacizumab.

Abstract
PURPOSE To investigate the association between the vascular endothelial growth factor (VEGF) gene polymorphism and the response to anti-VEGF treatment for choroidal neovascularization (CNV) in highly myopic eyes. DESIGN Retrospective cohort study. PARTICIPANTS A total of 357 unrelated highly myopic Japanese patients with axial lengths ≥26.0 mm in both eyes were eligible, and 83 patients who received anti-VEGF therapy for CNV and could be followed for more than 1 year were included. METHODS We genotyped a functional single nucleotide polymorphism in the VEGF gene, rs2010963. The associations between the distribution of the rs2010963 genotype and the number of eyes with maintained or improved visual acuity (VA) were analyzed. Furthermore, multivariable logistic regression analysis was performed to adjust for 7 possible prognostic factors, including age, sex, CNV size, CNV location, administration of loading dose, pretreatment VA, and number of additional treatments. MAIN OUTCOME MEASURES The primary end point was maintenance of VA, and secondary end points were progression of chorioretinal atrophy (CRA) and recurrence of CNV. RESULTS Mean age and mean axial length were not significantly different among 3 genotypes of rs2010963. The percentage of eyes with maintained or improved VA was significantly higher with the G allele of rs2010963 (P =0.016), and stepwise analysis revealed that both rs2010963 and CNV size were associated with VA maintenance (P =0.040 and 0.033, respectively). The secondary analysis revealed that administration of a loading dose was significantly associated with both CRA progression (P =0.031) and recurrence of CNV (P =0.020), whereas rs2010963 was not. CONCLUSIONS These results suggest that the VEGF polymorphism influences the VA prognosis in highly myopic eyes with CNV within 1 year after anti-VEGF treatment. This association was still observed after removing its confounding effect through CNV size. The rs2010963 polymorphism was not associated with CNV recurrence or CRA progression, which indicates that these changes are not tied to intrinsic factors and may be controllable by improving treatment methods.

Abstract
PURPOSE To assess the effects of intravitreal bevacizumab injections in the treatment of extrafoveal choroidal neovascularization (CNV) associated with pathologic myopia. METHODS Patients diagnosed with pathologic myopia complicated by extrafoveal CNV were considered in this prospective, open-label interventional study. All patients underwent a complete ophthalmologic examination, including Early Treatment Early of Diabetic Retinopathy Study (ETDRS) visual acuity measurement, optical coherence tomography, and fluorescein angiography. The protocol treatment included a first injection, followed by repeated injections over a 24-month follow-up period on the basis of optical coherence tomography and angiographic features, monitored monthly. Primary outcomes were the mean changes in best-corrected visual acuity and the proportion of eyes gaining at least 15 letters at the 24-month examination. Secondary outcomes included central macular thickness, size of the CNV, and extension to the fovea. RESULTS Fifteen patients were included in the study. Mean best-corrected visual acuity changed from 0.47 logarithm of the minimum angle of resolution (20/60 Snellen equivalent) at baseline to 0.22 logarithm of the minimum angle of resolution (20/30 Snellen equivalent) at the 24-month examination. An improvement of at least 3 ETDRS lines was achieved by 7 eyes (46.6%) at the 24-month examination. Mean central macular thickness changed from 313 μm to 254 μm at the 24-month examination (P = 0.008). Mean CNV size decreased from 348 μm2 to 251 μm2 at 24 months (P = 0.029). CONCLUSION Intravitreal bevacizumab injection is a beneficial treatment for extrafoveal CNV associated with pathologic myopia.

Abstract
Purpose. To investigate aqueous concentrations of vascular endothelial growth factor (VEGF) in eyes with myopic choroidal neovascularization (CNV). Methods. Aqueous samples were collected, and VEGF concentrations were measured by enzyme-linked immunosorbent assay in 16 eyes (16 patients) with active myopic CNV, 23 eyes (16 patients) with high myopia without myopic CNV, and 8 control eyes (7 patients). Differences in the concentrations of VEGF in each group were compared. Results. The estimated mean VEGF concentrations were significantly lower in eyes with myopic CNV (82.0 pg/mL) (P = 0.016
) and with high myopia without myopic CNV (58.9 pg/mL) (P < 0.001) compared with controls (116.6 pg/mL). The estimated mean VEGF concentration was significantly (P < 0.05) higher in eyes with myopic CNV than in those without myopic CNV in highly myopic eyes. In eyes with high myopia with and without CNV, the VEGF concentration was significantly (stepwise regression analysis, R = 0.325, P = 0.044) associated with the presence of myopic CNV but not with age, axial length, or intraocular pressure. Conclusion. Increased levels of VEGF may play a role in the pathogenesis of CNV in highly myopic eyes.

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
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
PURPOSE To evaluate changes in macular morphology due to myopic choroidal neovascularization (CNV), using spectral-domain optical coherence tomography (SD-OCT). METHODS In all, 22 eyes with recent-onset untreated CNV underwent 1 intravitreal injection of anti-vascular endothelial growth factor (anti-VEGF), followed by a pro-re-nata regimen. SD-OCT was performed at baseline (before first administration of anti-VEGF treatment) and month 1, and 2; macular morphologic changes and outer retina characteristics (SD-OCT findings) associated with CNV activity were evaluated. Sensitivity and specificity were calculated for SD-OCT findings using fluorescein angiography (FA) as standard reference. RESULTS Mean central retinal thickness (CRT) showed no significant reduction from baseline (284±98 μm) to month 1 (257±74 μm) and month 2 (263±72 μm). A hyper-reflective lesion with fuzzy borders (fuzzy area), and 'absent or altered' IS/OS junction were the only SD-OCT findings associated with CNV activity (P<0.0001). Both these SD-OCT findings showed good sensitivity and specificity (95.1 and 96.0% (95% CI: 0.87-0.89), respectively, for the fuzzy area; 87.9 and 66.7% (95% CI: 0.65-0.87), respectively, for 'absent or altered' IS/OS junction) when compared with FA leakage (standard reference). CONCLUSIONS Outer retina characteristics (ie, hyper-reflective lesion with fuzzy borders, and 'absent or altered' IS/OS junction) appear more meaningful than CRT in the evaluation of myopic CNV activity. These SD-OCT findings show overall good sensitivity and specificity when compared with FA leakage (standard reference), and could be considered as an alternative diagnostic tool to FA for myopic CNV monitoring.

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.
