Abstract
Most of world's scientists consider the fast-growing incidence of myopia a problem of great social importance due to associated increase in complicated myopia that leads to disability among the working-age population. This is a review on complicated myopia and myopic maculopathy that covers the history of research in this field, principles of classification, and etiological factors. It also deals with choroidal neovascularization (CNV), which often follows, and its treatment options, including anti-VEGF therapy. Possible complications of the latter are described as well. Literature search was done using PubMed, eLIBRARY, and Scopus text databases. A total of 61 sources, both Russian and foreign, were analyzed. Current clinical knowledge of different types of myopic maculopathy is still insufficient and the gaps are likely to be filled using modern methods of detailed in vivo examination of both sclera and choroidea. Anti-VEGF therapy has proved most effective in treating myopic maculopathy-associated neovascularization, however, a systematic approach to patient selection and management is yet needed.

Abstract
Ocular angiogenesis and macular oedema are major causes of sight loss across the world. Aberrant neovascularisation, which may arise secondary to numerous disease processes, can result in reduced vision as a result of oedema, haemorrhage, and scarring. The development of antivascular endothelial growth factor (anti-VEGF) agents has revolutionised the treatment of retinal vasogenic conditions. These drugs are now commonly employed for the treatment of a plethora of ocular pathologies including choroidal neovascularisation, diabetic macular oedema, and retinal vein occlusion to name a few. In this paper, we will explore the current use of anti-VEGF in a variety of retinal diseases and the impact that these medications have had on visual outcome for patients.

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.

Evaluation of Idiopathic Choroidal Neovascularization with Indocyanine Green Angiography in Patients Undergoing Bevacizumab Therapy. J Ophthalmol 2015; 2015:642624. [PMID: 26113990 PMCID: PMC4465762 DOI: 10.1155/2015/642624] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2015] [Revised: 05/17/2015] [Accepted: 05/24/2015] [Indexed: 12/03/2022] Open
Abstract
Purpose. To examine the clinical implications of change in choroidal neovascularization (CNV) size on indocyanine green (ICG) angiography in subjects with idiopathic CNV undergoing bevacizumab therapy. Methods. The charts of subjects with an idiopathic CNV treated by a modified PRN regimen with intravitreal bevacizumab over a 12-month period were retrospectively reviewed. Results. There were 34 subjects included in the analysis. Baseline CNV sizes of less than 1.0 mm2 on ICG angiography correlated with complete CNV resolution (P = 0.0404), fewer injections delivered (P = 0.0002), and better Snellen visual acuity (P = 0.0098) at 12 months. Subjects that experienced a 33% or more reduction in CNV size on ICG angiography at 2 months had complete CNV resolution (P = 0.0047) and fewer injections (P < 0.0001) at 12 months compared to subjects that did not experience a 33% or more reduction in CNV size on ICG angiography at 2 months. Conclusions. Smaller baseline CNV size on ICG angiography resulted in better visual acuity and fewer injections at 12 months, and a reduction of 33% or more in CNV size after 2 months may predict a better clinical course in subjects with idiopathic CNV undergoing bevacizumab therapy.

Abstract
OBJECTIVES The aim of this study is to systematically review the evidence for anti-vascular endothelial growth factor (VEGF) therapy in choroidal neovascularisation secondary to conditions other than age-related macular degeneration. DATA SOURCES MEDLINE, MEDLINE in-process, EMBASE and CENTRAL databases and conference abstracts were searched (from inception to Jan 2014). STUDY ELIGIBILITY CRITERIA, PARTICIPANTS AND INTERVENTIONS Randomised and non-randomised comparative studies with follow-up of at least 6 months were included and were used to assess clinical effectiveness. STUDY APPRAISAL AND SYNTHESIS METHOD Risk of bias was assessed using the Cochrane risk of bias tool and modified Newcastle-Ottawa Scale. Meta-analysis was not possible due to methodological heterogeneity. RESULTS 16 studies met the inclusion criteria (1091 eyes; 963 pathological myopia, 74 other conditions). There was large variation in risk of bias across studies. An improvement in best-corrected visual acuity in anti-VEGF arms over comparators was reported in all studies. The proportion of patients improving by at least 15 letters in anti-VEGF arms ranged from 27.3% to 70%. There were no significant differences between bevacizumab and ranibizumab. LIMITATIONS Owing to the rarity of choroidal neovascularisation secondary to conditions other than age-related macular degeneration or pathological myopia, there are unlikely to ever be sufficiently powered trials in these populations. CONCLUSIONS Bevacizumab and ranibizumab appear to be effective in improving visual acuity for patients with choroidal neovascularisation secondary to conditions other than age-related macular degeneration. The evidence base is strongest for choroidal neovascularisation secondary to pathological myopia, however, based on current evidence and likely pharmacological pathways, clinicians should consider treatment with either bevacizumab or ranibizumab for rarer causes.

Abstract
PURPOSE To evaluate and compare the 12-month outcomes of two different initial dosing regimens of intravitreal ranibizumab for myopic choroidal neovascularization (CNV). METHODS We retrospectively reviewed the medical records of 46 consecutive, treatment-naive eyes which received intravitreal ranibizumab for subfoveal and juxtafoveal CNV secondary to pathologic myopia with a follow-up of 12 months. Two groups were created according to different initial dosing regimens: group 1 included 25 eyes treated by a single intravitreal injection; group 2 included 21 eyes treated by three consecutive monthly injections. Additional injections were performed if needed. Patients' demographic data, best-corrected visual acuity (BCVA), recurrence of CNV and total number of treatments were recorded and evaluated. RESULTS There was no significant difference between two groups among baseline demographic data. At 12 months, the mean logMAR BCVA improved from 0.58 to 0.23 in group 1 and from 0.55 to 0.22 in group 2 (both p < 0.001; Wilcoxon signed-rank test). The mean logMAR BCVA at 12 months did not differ significantly. The average number of injections was 2.32 (SD 1.22) in group 1 and 3.57 (SD 1.12) in group 2 (p = 0.001; two-tailed t-test). During the follow-up, 17 of 25 eyes in group 1 and 5 of 21 eyes in group 2 received additional injections (p = 0.004). CONCLUSIONS Similar visual improvement was achieved in both groups. Although the eyes with a loading dose of 3 monthly injections required a higher number of total injections over 1 year, there was a much lower rate of retreatment needed.

Abstract
Intravitreal injections of ranibizumab (IVR) and bevacizumab (IVB) have both been used as treatments for myopic choroidal neovascularisation. We aimed to produce a meta-analysis of published literature comparing IVR with IVB for the treatment of myopic choroidal neovascularisation, by searching electronic databases from January 1950 to March 2013. Our search produced three suitable studies that reported on 117 patients in total. The results of the meta-analysis demonstrated that the mean number of lines improvement after IVR appeared better compared with IVB [fixed effects model: SMD = 0.46, 95% CI (0.09, 0.83), z = 2.44, p = 0.01]. The number of patients who had a greater than 3 line improvement was similar between groups [fixed effects model: RR = 0.95, 95% CI (0.67, 1.32), z = 0.33, p = 0.74]. At follow up there was no difference in number of those who had an absence of leakage [fixed effects model: RR = 1.04, 95% CI (0.93, 1.16), z = 0.64, p = 0.52]. There was no statistical significance between the two groups in relation to the number of injections [random effects model: SMD = −0.25, 95% CI (−1.12, 0.61), z = 0.57, p = 0.57]. Early evidence therefore suggests that intravitreal injections of ranibizumab are comparable to intravitreal injections of bevacizumab in the treatment of myopic choroidal neovascularisation. Both treatments result in a statistically significant increase in visual acuity with high numbers of patients maintaining stable vision. Further studies are still needed to strengthen results.

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
Degenerative ocular conditions, such as age-related macular degeneration, diabetic retinopathy, retinal vein occlusions, and myopic degeneration, have become a major public health problem and a leading cause of blindness in developed countries. Anti-vascular endothelial growth factor (VEGF) drugs seem to be an effective and safe treatment for these conditions. Ranibizumab, a humanized monoclonal antibody antigen-binding fragment, which inhibits all biologically active isoforms of VEGF-A, is still the gold standard treatment for the majority of these pathological entities. In this review, we present the results of the most important clinical trials concerning the efficacy and safety of ranibizumab for the treatment of degenerative ocular conditions.

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.

Combined therapy with bevacizumab and photodynamic therapy for myopic choroidal neovascularization: A one-year follow-up controlled study. Int J Ophthalmol 2014; 7:335-9. [PMID: 24790881 DOI: 10.3980/j.issn.2222-3959.2014.02.26] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2013] [Accepted: 12/19/2013] [Indexed: 11/02/2022] Open
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
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
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 This paper aims to describe the current situation of choroidal neovascularization (CNV) treatment. PROCEDURES MEDLINE (2001-2013) was searched for original research studies (phase I, II, III), abstracts and review articles concerning CNV therapy, and other related articles. Selected information from related websites was also included. RESULTS The management of CNV was developed through laser photocoagulation and photodynamic therapy, and has now evolved into anti-vascular endothelial growth factor (VEGF) use. Patients have achieved better visual acuity and toleration with the development of this therapy strategy. Combination therapy appears to offer a reduced retreatment frequency and long-term maintenance of the benefit with appropriate combination. Other treatment explorations with anti-inflammation and anti-VEGF are also ongoing. CONCLUSIONS Anti-VEGF monotherapy has become the first treatment for CNV patients. The investigation of other therapy strategies may prolong the interval of treatment and provide alternatives to CNV treatment.
