Abstract
PURPOSE To investigate the predictors of macular chorioretinal atrophy, consisting of patchy atrophy (PA) at the macula and choroidal neovascularization (CNV)-related macular atrophy (CNV-MA), during treatment with ranibizumab or aflibercept for myopic CNV (mCNV) and its impact on visual outcomes. METHODS This retrospective study included 82 eyes with treatment-naïve mCNV who were treated with pro re nata injections of ranibizumab or aflibercept. RESULTS Nine eyes (11.0%) presented with macular PA at baseline (PA group), and 73 eyes (89.0%) did not (non-PA group). VA improved during the first year in the non-PA group; a similar trend was noted in the PA group until 3 months after initial treatment. This improvement was maintained until 24 months ( P < 0.001) in the non-PA group, but not in the PA group. In the PA group, macular chorioretinal atrophy progressed faster ( P < 0.0001), and CNV-MA was more frequent during the 2 years of treatments ( P = 0.04). Even non-PA group eyes sometimes developed CNV-MA (42% at Month 24) if they had a larger CNV and thinner subfoveal choroidal thickness at baseline, resulting in poorer visual prognosis ( P < 0.01). CONCLUSION Macular PA at baseline was a risk factor for CNV-MA development and was associated with poor visual outcomes.

Three cases of macular retinal detachment exacerbated during follow-up with myopic foveoschisis around myopic choroidal neovascularization. Am J Ophthalmol Case Rep 2023; 32:101899. [PMID: 37564973 PMCID: PMC10410127 DOI: 10.1016/j.ajoc.2023.101899] [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: 02/09/2023] [Revised: 06/07/2023] [Accepted: 07/19/2023] [Indexed: 08/12/2023] Open
Abstract
Purpose Myopic choroidal neovascularization (CNV) and myopic traction maculopathy are major complications of pathologic myopia, and myopic foveoschisis (MF) is one of several symptoms that can be included under the general term "myopic traction maculopathy"; however, only a few cases will have MF around the myopic CNV. We report three cases with MF around myopic CNV that followed different clinical courses observed using swept-source optical coherence tomography. Observations Case 1 was a 69-year-old woman with an axial length of 29.71 mm, myopic CNV, and MF in the left eye. One month after intravitreal injection of ranibizumab (IVR), a macular retinal detachment (RD) expanded. Vitrectomy and gas tamponade were performed during month 2; the macular RD and MF resolved gradually thereafter. Case 2 was a 54-year-old man with an axial length of 30.59 mm, myopic CNV, and MF in the right eye; after IVR, a macular RD developed and gradually expanded until month 4; the RD and MF resolved spontaneously and resolved during month 8. Case 3 was a 66-year-old woman with an axial length of 28.63 mm, myopic CNV, and MF in the left eye. A macular RD expanded 1 month after a previous vitrectomy for MF; after intravitreal injection of aflibercept, the macular RD and MF resolved gradually in month 12. In all cases, the CNV was accompanied by subretinal fluid, and two of the three cases had outer lamellar holes. Conclusion and Importance The MF around the myopic CNV may lead to exacerbated MF and RD during follow-up, and the subretinal fluid caused by the CNV might facilitate MF progression. Since this condition is rare, further investigation of this entity is needed to determine appropriate management.

Abstract
PURPOSE To investigate the 10-year visual outcome and chorioretinal atrophy after a single intravitreal ranibizumab injection followed by a pro re nata regimen for myopic macular neovascularization in pathologic myopia, and to identify the factors associated with 10-year best-corrected visual acuity (BCVA). METHODS This retrospective observational study evaluated 26 consecutive treatment-naïve eyes (26 patients) with myopic macular neovascularization in pathologic myopia who underwent a single intravitreal ranibizumab followed by a pro re nata regimen of intravitreal ranibizumab and/or intravitreal aflibercept injection and observed over 10 years. We assessed changes in BCVA and morphological parameters, including the META-PM Study category as a chorioretinal atrophy index. RESULTS The logarithm of the minimum angle of resolution BCVA changed from 0.36 (Snellen, 20/45) ± 0.39 to 0.39 (20/49) ± 0.36 over 10 years of observation. Compared to baseline, 1-year BCVA improved ( P = 0.002), whereas 2 to 10-year BCVA was not significantly different. Total injection frequency was 3.8 ± 2.6. In none of the eyes, 10-year BCVA was 20/200 or less. Ten-year BCVA correlated with baseline BCVA ( P = 0.01, r = 0.47). The META-PM Study category progressed in 60% of eyes. There were no drug-induced complications. CONCLUSION Best-corrected visual acuity in eyes with myopic macular neovascularization in pathologic myopia was maintained for 10 years after a single intravitreal ranibizumab followed by a pro re nata regimen without drug-induced complications. The META-PM Study category progressed in 60% of eyes, especially those with older baseline age. Early diagnosis and treatment of myopic macular neovascularization are essential to maintain good long-term BCVA.

Abstract
PURPOSE To investigate the development and progression patterns of macular neovascularization (MNV)-related atrophies in eyes with pathologic myopia. METHODS Twenty-seven eyes of 26 patients with MNV followed from its onset to progression to macular atrophy were studied. A longitudinal series of autofluorescence and optical coherence tomography images were examined for the patterns of MNV-related atrophy. Changes in best-corrected visual acuity were determined for each pattern. RESULTS The mean age was 67.2 ± 8.7 years. The mean axial length was 29.6 ± 1.5 mm. Three patterns of atrophy were identified: multiple-atrophic pattern, 63% of the eyes had small atrophies occurring at multiple sites around the MNV edge; single-atrophic pattern, 18.5% had atrophies occurring only on one side of the MNV edge; and exudation-related pattern, 18.5% had atrophy occurring within a previous serous exudation or hemorrhagic area and slightly away from the MNV edge. Eyes with atrophies in multiple-atrophic and exudation-related patterns progressed to large macular atrophies involving the central fovea and showed decrease in best-corrected visual acuity during the 3-year follow-up period. Eyes with single-atrophic pattern had a sparing of the fovea and had good recovery of the best-corrected visual acuity. CONCLUSION There are three patterns of MNV-related atrophy in eyes with pathologic myopia with different courses of progression.

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

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.

Abstract
PURPOSE To investigate long-term visual outcome in inferior posterior staphyloma (IPS) in each group classified based on macular complications and to examine the treatment effect for eyes with IPS with choroidal neovascularization (CNV). DESIGN Prospective clinical cohort study. PARTICIPANTS We analyzed 56 eyes of 43 consecutive patients with IPS who were followed for 4 years. METHODS We classified eligible eyes into 3 groups based on baseline findings: eyes without CNV or retinal exudate (no-exudate group), eyes without CNV and with retinal exudate (exudate group), and eyes with CNV (CNV group). We investigated the best-corrected visual acuity (BCVA) and associated parameters for 4 years. RESULTS BCVA declined during 4 years only in the exudate group (P = .002), whereas it was maintained for 4 years in the no-exudate and CNV groups (P = .53 and .20, respectively). Baseline BCVA was lower in the CNV group than in the exudate group (P = .004); however, the 4-year BCVA was not (P = .84). The 4-year BCVA was associated with baseline BCVA in all groups. Eyes in the CNV group required 9.0 ± 8.7 anti-vascular endothelial growth factor therapy in 4 years. CONCLUSIONS Better baseline BCVA in eyes with exudative IPS without CNV spontaneously declined in 4 years, whereas worse baseline BCVA in eyes with IPS with CNV did not, probably because of treatment for retinal exudate from CNV. Anti-vascular endothelial growth factor therapy would be effective for long-term maintenance of BCVA in eyes with IPS with CNV, similar to other diseases with CNV.

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

Abstract
PURPOSE To evaluate the prevalence and visual outcomes of macular Bruch membrane (BM) defects in patients treated with anti-vascular endothelial growth factors (VEGF) for choroidal neovascularization secondary to pathological myopia (mCNV). METHODS Single-center retrospective observational case series of 68 eyes from 62 patients with mCNV treated with one anti-VEGF injection followed by a pro re nata (1 + PRN) regimen. A minimum follow-up of 6 months was defined. Chorioretinal atrophy was assessed by fundus examination, fluorescein angiography, and SD-OCT. RESULTS Median follow-up was 28.5 (range 6-89) months with a median number of 5 anti-VEGF injections. At baseline, 27.9% of eyes had macular BM defects increasing to 36.8% during follow-up (p<0.001). Eyes without macular BM defects at the baseline had higher BCVA at the last observation than patients with BM defects (p=0.003). An increase of 5 or more ETDRS letters was more frequent in eyes without BM defects (p=0.001). At the end of follow-up, mCNV-related macular atrophy was present in 44.1%; out of which, 83.3% presented macular BM defects (p<0.001). Eyes with mCNV-related macular atrophy without BM defects had a significant increase of best-corrected visual acuity compared with eyes with mCNV-related macular atrophy and BM defect (p=0.002). CONCLUSIONS Macular Bruch membrane defects are often seen in mCNV and have a significant impact in visual acuity and prognosis. Eyes with macular BM defects have a poorer response and worse visual outcomes after anti-VEGF therapy.

Methods This 5-year, prospective, multicenter, observational, study enrolled 30,138 patients across all approved ranibizumab indications from outpatient ophthalmology clinics. 297 consenting patients (≥18 years) with mCNV who were treatment-naïve or prior-treated with ranibizumab or other ocular treatments were enrolled, and treated with ranibizumab according to the local product label. The main outcomes are visual acuity (VA; Early Treatment Diabetic Retinopathy Study letters or equivalent), adverse events during the study, and treatment exposure over 1 year. Results are presented by prior treatment status of the study eye and injection frequency. Results Of the 297 mCNV patients recruited in the study, 108 were treatment-naïve and 175 were prior ranibizumab-treated. At baseline, the mean age of patients was 57.6 years, and 59.0 years and 80.6% and 65.7% were female in the treatment-naïve and prior ranibizumab-treated groups, respectively. Most were Caucasian (treatment-naïve, 88.9%; prior ranibizumab-treated, 86.9%). The mean (±standard deviation [SD]) VA letter changes to 1 year were +9.7 (±17.99) from 49.5 (±20.51) and +1.5 (±13.15) from 58.5 (±19.79) and these were achieved with a mean (SD) of 3.0 (±1.58) and 2.6 (±2.33) injections in the treatment-naïve and prior ranibizumab-treated groups, respectively. Presented by injection frequencies 1–2, 3–4 and ≥5 injections in Year 1, the mean (SD) VA changes were +15.0 (±14.70), +7.7 (±19.91) and −0.7 (±16.05) in treatment-naïve patients and +1.5 (±14.57), +3.1 (±11.53) and −3.6 (±11.97) in prior ranibizumab-treated patients, respectively. The safety profile was comparable with previous ranibizumab studies. Conclusions Ranibizumab treatment for mCNV showed robust VA gains in treatment-naïve patients and VA maintenance in prior ranibizumab-treated patients in a clinical practice setting, consisting mainly of Caucasians. No new safety signals were observed during the study.

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

Abstract
The aim of the present study was to investigate the potential mechanism of retinopathy of prematurity (ROP) using an oxygen-induced retinopathy (OIR) mouse model. For experiments, mice were divided into either the OIR group or control group. Fluorescein isothiocyanate-dextran cardiac perfusion and stretched retina preparation were performed. The total retina area, area of instillation, density of microvascular network, area of new blood vessels, vein width and the tortuosity of arteries were measured. Next, mice were randomly assigned into the PBS, soluble TEK receptor tyrosine kinase (sTie2)-fusion protein (Fc), angiopoietin 1 (Ang1), ranibizumab, ranibizumab + sTie2-Fc and ranibizumab + Ang1 treatment groups. Following housing for 5 days, the body weight of each mouse was recorded. Mice in the OIR group presented smaller total retina area and larger area of instillation, larger area of new blood vessels, and higher microvascular network density compared with the control PBS group. Obvious retinal vein dilatation and arterial tortuosity were identified in the OIR group. The amount of endotheliocyte nuclei of new vessels beyond the inner limiting membrane was larger in the OIR group compared with the control group. Furthermore in the next set of experiments, a larger area of instillation, smaller area of new blood vessels and decreased amount of endotheliocyte nuclei of new vessels were observed in the sTie2-Fc group, Ang1 group, ranibizumab group, ranibizumab + sTie2-Fc group and ranibizumab + Ang1 group compared with the PBS group. Specifically, the ranibizumab + sTie2-Fc group and ranibizumab + Ang1 group demonstrated markedly reduced retina instillation area and microvascular network density in the instillation area. Total retina area and body weight following 10 days of the experiment for the ranibizumab group were significantly lower compared with other groups. In conclusion, the combined regulation of the Ang/Tie2 and the vascular endothelial growth factor (VEGF)/VEGF receptor pathways markedly increased the efficacy of treatment with retinal neovascularization (RNV). Regulation of these pathways has a potential for treating RNV, in particular ROP.

Abstract
PURPOSE To investigate morphological changes in myopic choroidal neovascularization (mCNV) using optical coherence tomography-angiography (OCT-A) after treatment with ranibizumab. METHODS Retrospective analysis of consecutive patients over a 24-month period. All treatment-naïve mCNV were imaged at baseline with color pictures, spectral-domain OCT and OCT-A, and fluorescein angiography in selected cases. CNV morphology was classified at baseline and at 6 months. The CNV lesion surface was also compared. RESULTS Twenty-nine patients with a mean age of 70.3 ± 10.1 years were included. They received a mean number of 2.65 injections over 6 months. Best-corrected visual acuity improved from 62.2 to 68.5 letters (p = 0.004), with regression of exudation in 24 eyes (82.7%). Baseline CNV was classified into tree-in-bud (16 eyes), medusa (9 eyes), or sea-fan (4 eyes) pattern. At 6 months, no abnormal blood flow was observed in CNV in 13 eyes. Eyes with complete regression or evolution towards an indistinct pattern showed more often a complete regression of exudation than eyes with unchanged pattern (p = 0.007). The mean CNV surface significantly decreased from 0.19 to 0.08 mm2 (p < 0.0001). CONCLUSION An unchanged pattern was more often associated with exudation persistence, while a complete regression or evolution towards indistinct pattern was always associated with vascular inactivity. However, variable changes in mCNV were observed after anti-VEGF. Thus, OCT-A could be more useful in the diagnosis than in the follow-up of mCNV.

Abstract
PURPOSE The aim of this study was to evaluate the 9-year outcome of ranibizumab monotherapy for myopic choroidal neovascularization (mCNV). METHODS This was a retrospective, nonrandomized, multicentric study to evaluate the long-term outcomes of mCNV treated with ranibizumab monotherapy for at least 9 years according to a strict pro re nata regimen. RESULTS Seventeen eyes of 17 patients (12 women, mean age 57.9 ± 7.7 years) were included. The mean follow-up period was 112.4 ± 3.9 months (range 108-120). The mean difference in best-corrected visual acuity (BCVA) from baseline to the last follow-up was +1.2 ± 15.6 ETDRS letters (p = 0.004, between initial vs. 12 and 24 months). The mean total number of intravitreal injections for each patient was 1.24 ± 1.70 per year (range 2-25). No systemic adverse reactions related to the drug treatment were detected during the 9-year follow-up period. CONCLUSIONS Long-term ranibizumab monotherapy treatment induces unchanged or better BCVA compared to baseline after a 9-year treatment in almost all eyes.

Abstract
Myopic choroidal neovascularization (CNV) is one of the most vision-impairing complications in patients with pathologic myopia. It is also one of the most frequently encountered non.age-related macular degeneration causes of CNV and affects young patients in the working age group. Fluorescein angiography (FA) and spectral domain optical coherence tomography (OCT) are generally indicated to confirm the diagnosis of active myopic CNV before initiation of treatment. Without treatment, natural history studies have shown that the vision outcome can be very poor. More recently, a number of retrospective, prospective and phase 3, multicenter, randomized controlled trials have established the safety and efficacy of intravitreal anti.vascular endothelial growth factor (VEGF) agents for the treatment of myopic CNV. Long-term follow-up studies have found that some of the initial vision gained after intravitreal anti-VEGF therapy may not be maintained, owing to the presence and progression of chorioretinal atrophy (CRA) adjacent to the CNV. Further research on clinical and imaging characteristics may elucidate the prognostic factors that are crucial to optimizing the treatment and prevention of visual impairment associated with myopic CNV.

Abstract
Pathologic myopia is a leading cause of visual impairment. Development of myopic choroidal neovascularization (CNV) is one of the most common complications that leads to central vision loss in patients with pathologic myopia. If left untreated, it can cause scarring with expanding macular atrophy leading to irreversible visual loss in a period as short as 5 years. Advancements in multimodal imaging technology have furthered our understanding of the condition; however, further studies are necessary to extend its utility in the diagnosis of myopic CNV. Intravitreal anti-vascular endothelial growth factor (anti-VEGF) therapy has become the standard-of-care and the recommended first-line treatment option for myopic CNV. Long-term studies have demonstrated that early treatment of confirmed myopic CNV cases with an intravitreal anti-VEGF agent is useful to avoid late-stage complications. This strategy has also been shown to achieve visual outcome improvements for up to 4 years and visual stabilization up to 6 years. This review article provides an overview of the current knowledge on myopic CNV and discusses recent updates in the diagnosis and management of the condition. Furthermore, treatment recommendations are provided based on the authors' expert opinions.

Abstract
Pathologic myopia (PM) is the only myopia that causes the loss of best-corrected visual acuity. The main reason for best-corrected visual acuity loss is complications specific to PM, such as myopic maculopathy, myopic traction maculopathy, and myopic optic neuropathy (or glaucoma). The meta-analyses of the PM study group (META-PM study) made a classification system for myopic maculopathy. On the basis of this study, PM has been defined as eyes having atrophic changes equal to or more severe than diffuse atrophy. Posterior staphyloma and eye deformity are important causes of developing vision-threatening complications. Posterior staphyloma is unique to PM, except for inferior staphyloma due to tilted disc syndrome. It is defined as an outpouching of the wall of the eye that has a radius of curvature that is less than the surrounding curvature of the wall of the eye. The mechanical load onto the important region for central vision (optic nerve and macula) is not comparable between eyes with and without posterior staphyloma. Three-dimensional magnetic resonance imaging is a powerful tool to analyze the entire shape of the eye. When ultra-widefield optical coherence tomography is available, it is expected to be a new tool that will surpass 3-dimensional magnetic resonance imaging. In the future, preventive therapies targeting staphyloma and eye deformity are expected before vision-threatening complications develop and it is too late for patients.

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.

Chang KJ, Cheng CK, Peng CH. Clinical characteristics and visual outcome of macular hemorrhage in pathological myopia with or without choroidal neovascularization. Taiwan J Ophthalmol 2016; 6:136-140. [PMID: 29018729 PMCID: PMC5525620 DOI: 10.1016/j.tjo.2016.05.007] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2016] [Revised: 05/15/2016] [Accepted: 05/23/2016] [Indexed: 11/26/2022] Open
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
INTRODUCTION Myopic choroidal neovascularization (CNV) is the most common cause of CNV in those under 50 years of age. It is a significant cause of visual loss in those with pathologic myopia. The current standard of care involves therapy with intravitreal inhibitors of vascular endothelial growth factor (VEGF). AREAS COVERED The epidemiology of myopia, high myopia, pathologic myopia, and myopic CNV is reviewed, along with a brief discussion of historical treatments. The pharmacology of the three most commonly used anti-VEGF agents is discussed, with an emphasis on the licensed drugs, ranibizumab and aflibercept. A comprehensive clinical approach to diagnosis and treatment of myopic CNV is presented. EXPERT OPINION The current standard of care for myopic CNV is intravitreal inhibition of VEGF, with ranibizumab and aflibercept licensed for intraocular use. The diagnosis, OCT features of disease activity and retreatment algorithm for myopic CNV is different from wet age-related macular degeneration. In the long-term, myopic CNV may be associated with gradual, irreversible visual loss due to progressive chorioretinal atrophy, for which there is currently no treatment.

Abstract
Purpose: To describe retinal changes during Spectral Domain Optical Coherence Tomography (SD-OCT) guided bevacizumab treatment for neovascular age- related macular degeneration (AMD). Settings and Design: Single center observational study. Materials and Methods: We confirmed wet AMD in 47 eyes of 45 patients by fluorescein angiography and SD-OCT. After bevacizumab injection, we examined the patients at 4-week intervals. During each follow-up control, we performed SD-OCT and a complete ophthalmic examination. Criteria for reinjection were visual acuity loss of more than five ETDRS letters, and/or increase of central retinal thickness, sub-retinal fluid, intra-retinal fluid, pigment epithelium detachment. If reinjection criteria were not met, we advised the patient to return in 4 weeks’ time for the next scheduled follow-up. We used 3-dimensional SD-OCT to measure photoreceptor defects and sub-retinal fibrosis. The main efficacy endpoints were the SD-OCT measurements of the size of photoreceptor defects, the size of external membrane defects and the central retinal thickness. Results: Over the 12 months study period, the percentage of scans in 3-D imaging mode showing visible defects of the junction between inner and outer segments of photoreceptors increased from 38.96 to 53.8%. The percentage of scans in 3-D imaging mode with visible sub-retinal fibrosis increased from 33 to 52% and mean central retinal thickness decreased from 333 μm (96-900 μm) to 272 μm (P = 0.011). Conclusion: In long-term anti- Vascular endothelial growth factor (VEGF) treatment for neovascular AMD, photoreceptor defects and fibrosis progress despite a decrease in central retinal thickness and improvements in visual acuity. We would encourage further discussion as to whether this is the natural course of the disease or a result of the treatment.

Am J Ophthalmol 2015; 160:322-327.e2.

Abstract
PURPOSE To describe fundus autofluorescence (FAF) patterns of myopic choroidal neovascularization (CNV) treated with intravitreal ranibizumab and their correlation with visual acuity. DESIGN Prospective interventional case series. METHODS Twenty-seven eyes (27 patients) affected by myopic CNV were enrolled from January 2011 to January 2013. All patients underwent a complete ophthalmologic examination, including best-corrected visual acuity (BCVA) determination and fundus autofluorescence (FAF). The patients underwent ranibizumab injections following a pro re nata treatment regimen. The main outcome measure was the identification of the FAF patterns of myopic CNV over a 12-month follow-up. The secondary outcome was the correlation of the FAF patterns with the BCVA. RESULTS At baseline 17 eyes (63%) showed a hyperautofluorescent pattern and 10 eyes (37%) a patchy pattern. BCVA changed from 0.48 ± 0.23 (logMAR) to 0.30 ± 0.32 at the 12-month examination (P = .027) in the hyper-FAF subgroup. In the subgroup showing the patchy pattern, the BCVA declined slightly from 0.51 ± 0.27 to 0.56 ± 0.37 (P = .53). The 14 eyes preserving the hyper-FAF pattern during the follow-up had a final BCVA of 0.20 ± 0.17, whereas the 9 eyes maintaining the patchy pattern showed a final BCVA of 0.60 ± 0.37 (P = .002). The atrophic area of the retinal pigment epithelium assessed on the basis of FAF increased from 1.27 ± 2.80 mm(2) to 1.83 ± 3.74 mm(2) at the 12-month examination (P = .016). The mean atrophic area increased by 0.37 mm(2) in the hyper-FAF subgroup and by 0.90 mm(2) in the patchy FAF subgroup. CONCLUSIONS Two main patterns were identified on FAF in myopic CNV and were related to the prognostic evolution, the hyperautofluorescent CNV being associated with a greater visual gain and fewer atrophic changes over a 12-month follow-up.

Abstract
Diabetic macular edema (DME) is a major cause of visual impairment. Although DME is generally believed to be a microvascular disease, dysfunction of the retinal pigment epithelium (RPE) can also contribute to its development. Advanced glycation end-products (AGE) are thought to be one of the key factors involved in the pathogenesis of diabetes in the eye, and we have previously demonstrated a rapid breakdown of RPE function following glycated-albumin (Glyc-alb, a common AGE mimetic) administration in monolayer cultures of fetal human RPE cells. Here we present new evidence that this response is attributed to apically oriented AGE receptors (RAGE). Moreover, time-lapse optical coherence tomography in Dutch-belted rabbits 48 h post intravitreal Glyc-alb injections demonstrated a significant decrease in RPE-mediated fluid resorption in vivo. In both the animal and tissue culture models, the response to Glyc-alb was blocked by the relatively selective RAGE antagonist, FPS-ZM1 and was also inhibited by ZM323881, a relatively selective vascular endothelial growth factor receptor 2 (VEGF-R2) antagonist. Our data establish that the Glyc-alb-induced breakdown of RPE function is mediated via specific RAGE and VEGF-R2 signaling both in vitro and in vivo. These results are consistent with the notion that the RPE is a key player in the pathogenesis of DME.

Abstract
Choroidal neovascularization (CNV) is the main cause of visual impairment in highly myopic patients younger than 50 years of age. There are different treatments for myopic CNV (mCNV), with 5- to 10-year outcomes currently. Chorioretinal atrophy is still the most important determinant factor for visual outcome. The purpose of this study is to provide an overview of the current treatments for mCNV, including laser, surgical management, verteporfin photodynamic therapy, and mainly anti-vascular endothelial growth factor therapy. Emerging treatment options are also discussed.

Abstract
Anti-VEGF-A therapy has become a mainstay of treatment for ocular neovascularisation and in cancer; however, their effectiveness is not universal, in some cases only benefiting a minority of patients. Anti-VEGF-A therapies bind and block both pro-angiogenic VEGF-Axxx and the partial agonist VEGF-Axxxb isoforms, but their anti-angiogenic benefit only comes about from targeting the pro-angiogenic isoforms. Therefore, antibodies that exclusively target the pro-angiogenic isoforms may be more effective. To determine whether C-terminal-targeted antibodies could inhibit angiogenesis, we generated a polyclonal antibody to the last nine amino acids of VEGF-A165 and tested it in vitro and in vivo. The exon8a polyclonal antibody (Exon8apab) did not bind VEGF-A165b even at greater than 100-fold excess concentration, and dose dependently inhibited VEGF-A165 induced endothelial migration in vitro at concentrations similar to the VEGF-A antibody fragment ranibizumab. Exon8apab can inhibit tumour growth of LS174t cells implanted in vivo and blood vessel growth in the eye in models of age-related macular degeneration, with equal efficacy to non-selective anti-VEGF-A antibodies. It also showed that it was the VEGF-Axxx levels specifically that were upregulated in plasma from patients with proliferative diabetic retinopathy. These results suggest that VEGF-A165-specific antibodies can be therapeutically useful.

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
AIM To examine the long-term outcomes of full macular translocation (FMT) for myopic choroidal neovascularisation (mCNV). METHODS We evaluated a consecutive case series of 60 eyes with mCNV that underwent FMT. We assessed the best-corrected visual acuity (BCVA), fundus photographs and fluorescein angiography images, and evaluated the anatomic and visual outcomes. RESULTS The mean follow-up period was 76.3 months. The macula was relocated successfully in all eyes. The mean distance of macular translocation was 2842 μm. The baseline BCVA was 0.78 logarithm of the minimum angle of resolution (logMAR) unit; the logMAR BCVA values at 1, 3 and 5 years postoperatively significantly (p<0.001) improved to 0.54 at 1 year and then remained stable. The new fovea was associated with enlargement of the myopic chorioretinal atrophy in 19 (31.7%) eyes. Subfoveal or juxtafoveal CNV at the translocated new fovea developed in five (8.3%) eyes. CONCLUSIONS FMT for mCNV maintained the improvement in VA for more than 5 years. However, postoperative complications and progression of chorioretinal atrophy due to myopia still seem to limit the visual improvement after FMT for mCNV.

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 evaluate the visual outcomes of choroidal neovascularization (CNV) secondary to pathological myopia in eyes treated with photodynamic therapy (PDT), and to determine the effect of lesion location and foveal involvement on visual prognosis. METHODS Interventional case series of 24 consecutive patients with myopic CNV treated with PDT. The main outcome measure was final LogMAR visual acuity (VA). RESULTS Of 24 eyes, the CNV lesion was subfoveal in 11 and extrafoveal in 13. Overall, the mean LogMAR VA at 24 months was 0.72. Extrafoveal CNV lesions achieved significantly better final VA compared with subfoveal CNV (LogMAR 0.45 vs 1.05, P=0.012). Eyes with extrafoveal CNV lesions were subdivided into foveal-sparing PDT (where the PDT laser spot did not involve the foveal center) and foveal-involved PDT (where the PDT laser covered the fovea). At all time points, the group with foveal-sparing PDT had significantly better VA compared with the foveal-involved group. The final LogMAR VA for the foveal-sparing PDT group was 0.26 compared with 1.00 for the foveal-involved PDT group (P=0.003). At 24 months, 77.8% of foveal-sparing PDT cases achieved VA of ≥ 20/40, compared with 25% of foveal-involved PDT cases and 9.1% of subfoveal CNV lesions (P=0.006). CONCLUSION For patients with myopic CNV, foveal-sparing PDT results in significantly better long-term visual outcomes compared with those with foveal-involved PDT. Foveal-sparing PDT may be of value for treatment of myopic CNV patients who are not suitable for treatment with anti-vascular endothelial growth factor injections.

Vascular endothelial growth factor gene and the response to anti-vascular endothelial growth factor treatment for choroidal neovascularization in high myopia. Ophthalmology 2013; 121:225-233. [PMID: 23953100 DOI: 10.1016/j.ophtha.2013.06.043] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2012] [Revised: 06/20/2013] [Accepted: 06/25/2013] [Indexed: 01/04/2023] Open
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.
