Abstract
Purpose To analyze publication trends and investigate research hotspots of aqueous humor (AH) studies. Methods A bibliometric study was conducted based on the Web of Science Core Collection (WOSCC). VOSviewer v. 1.6.18 was utilized to create a knowledge map visualizing the number of annual publications, the distribution of countries, international collaborations, author productivity, source journals and keywords in the field. Results A grand total of 4020 peer-reviewed papers concerning AH were retrieved from 2014 to 2023. The United States of America secured the top position among the most published countries and Duke University emerged as the most active institution. Stamer, WD contributed the most papers in this area. Investigative Ophthalmology & Visual Science was the most prolific journal in AH research. Retrieved publications mainly concentrated on the correlation between AH as a biomarker carrier and different ocular disorders. Six clusters were formed based on the keywords: (1) the diagnosis of endophthalmitis and AH pharmacokinetics; (2) the association of AH with pathogenesis and prognosis of glaucoma; (3) diagnosis and treatment of AH associated with uveitis; (4) the relationship between AH and refractive diseases of the eye; (5) the association of AH with mechanism and biomarkers of ocular tumorigenesis; (6) the indicators of AH associated with fundus disease. Conclusions This study unveiled present patterns of global collaboration, emerging frontiers, fundamental knowledge, research hotspots and current trends in AH.

Differences between pathologic and non-pathologic high myopia in 4-year outcomes of anti-VEGF therapy for macular neovascularization. Sci Rep 2024; 14:13399. [PMID: 38862630 PMCID: PMC11166914 DOI: 10.1038/s41598-024-64456-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2024] [Accepted: 06/10/2024] [Indexed: 06/13/2024] Open
Abstract
This retrospective observational study aimed to investigate the difference in 4-year outcomes of ranibizumab or aflibercept therapy for macular neovascularization (MNV) with high myopia between pathologic myopia (PM) and non-PM. This study was conducted at Kyoto University Hospital and included consecutive treatment-naïve eyes with active myopic MNV, in which a single intravitreal ranibizumab or aflibercept injection was administered, followed by a pro re nata (PRN) regimen for 4 years. Based on the META-PM study classification, eyes were assigned to the non-PM and PM groups. This study analyzed 118 eyes of 118 patients (non-PM group, 19 eyes; PM group, 99 eyes). Baseline, 1-year, and 2-year best-corrected visual acuity (BCVA) were significantly better in the non-PM group (P = 0.02, 0.01, and 0.02, respectively); however, the 3-year and 4-year BCVA were not. The 4-year BCVA course was similar in both groups. However, the total number of injections over 4 years was significantly higher in the non-PM than in the PM group (4.6 ± 2.6 vs. 2.9 ± 2.6, P = 0.001). Four-year BCVA significantly correlated only with baseline BCVA in both non-PM (P = 0.047, β = 0.46) and PM groups (P < 0.001, β = 0.59). In conclusion, over the 4-year observation period, the BCVA course after anti-VEGF therapy for myopic MNV was similar in the eyes with non-PM and those with PM; however, more additional injections in a PRN regimen were required in the eyes with non-PM compared to those with PM. Thus, more frequent and careful follow-up is required for the eyes with non-PM compared with those with PM to maintain long-term BCVA.

Graefes Arch Clin Exp Ophthalmol 2024; 262:1693-1722. [PMID: 37950753 PMCID: PMC11106160 DOI: 10.1007/s00417-023-06271-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Revised: 06/19/2023] [Accepted: 10/07/2023] [Indexed: 11/13/2023] Open
Abstract
PURPOSE This is, to our knowledge, the first network meta-analysis aiming to compare all treatment modalities for myopic choroidal neovascularization (CNV). METHODS After the electronic databases were searched, two independent reviewers screened titles, abstracts, full-texts, and extracted information. Primary endpoints were change in visual outcome and central retinal thickness. We used a network meta-analysis to compare treatment outcomes in the early (≤ 6 months) and late (> 6 months) phase. RESULTS We included 34 studies (2,098 eyes) in our network meta-analysis. In the early phase, the use of anti-VEGF led to a gain of 14.1 letters (95% CI, 10.8-17.4) compared to untreated patients (p < 0.0001), 12.1 letters (95% CI, 8.3-15.8) to photodynamic therapy (PDT) (p < 0.0001), 7.5 (95% CI, 1.2-13.8) letters to intravitreal triamcinolone acetonide (TCA) (p = 0.019), and - 2.9 letters (95% CI, - 6.0-0.2) to the combination of anti-VEGF and PDT (p = 0.065). In the later phase, these results were largely maintained. There were no significant differences in visual outcomes between patients treated with 1 + PRN and 3 + PRN. However, the 1 + PRN group received 1.8 (SD 1.3), while the 3 + PRN group received 3.2 (SD 0.9) injections within 12 months (p < 0.0001). CONCLUSION This network meta-analysis confirms that anti-VEGF is the most effective treatment for myopic CNV using the 1 + PRN treatment strategy.

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.

Abstract
The benign public perception of myopia (nearsightedness) as a visual inconvenience masks the severity of its sight-threatening consequences. Myopia is a significant risk factor for posterior pole conditions such as maculopathy, choroidal neovascularization and glaucoma, all of which have a vascular component. These associations strongly suggest that myopic eyes might experience vascular alterations prior to the development of complications. Myopic eyes are out of focus because they are larger in size, which in turn affects their overall structure and function, including those of the vascular beds. By reviewing the vascular changes that characterize myopia, this review aims to provide an understanding of the gross, cellular and molecular alterations identified at the structural and functional levels with the goal to provide an understanding of the latest evidence in the field of experimental and clinical myopia vascular research. From the evidence presented, we hypothesize that the interaction between excessive myopic eye growth and vascular alterations are tipping-points for the development of sight-threatening changes.

Abstract
Recent evidence has demonstrated that the global public health burden of myopia is rising rapidly. Highly myopic eyes are associated with increased frequency of eye disorders that can lead to irreversible visual impairment. With recent technological advancement in ophthalmic imaging modalities, various macular complications associated with pathologic myopia are being elucidated. The development and progression of myopic chorioretinal atrophy, myopic macular neovascularization, myopic traction maculopathy and dome-shaped macula are vision-threatening myopic macular diseases. In order to overcome the challenges in managing patients with pathologic myopia, it is important to have a complete understanding in the natural course of these myopic macular diseases. Standardising the classification criteria of pathologic myopia is essential for enhancing clinical surveillance. Personalised pharmaceutical therapy and surgical interventions will help to optimise the treatment outcomes in patients suffering from these myopic macular diseases.

Abstract
Objectives To evaluate incidence, predictors, and re-treatment outcome of recurrent myopic choroidal neovascularization (m-CNV). Methods Retrospective consecutive observational series. From year 2014 to 2019, 167 eyes of 167 patients of treatment naïve m-CNV were enrolled. 59 and 108 eyes were treated with intra-vitreal ranibizumab and bevacizumab mono-therapy, respectively. Recurrence was defined as re-appearance of CNV activity, confirmed on optical coherence tomography (OCT) after at least 3 months of cessation of anti-VEGF therapy. Incidence of recurrence, predictors and re-treatment outcomes were studied. Results Overall, mean age and spherical equivalence (SE) was 47.95 ± 14.72 years and -12.19 ± 4.93 D respectively. Males constituted 50.9%. 44 eyes (26.4%) had a recurrence during a mean follow up of 16.5 ± 12.86 months. Kaplan-Meier survival analysis showed the risk of recurrence was 8, 26 and, 33.6% at 6, 12 and 18 months, respectively. Age (p = 0.511), gender (p = 0.218), SE (p = 0.092), anti-VEGF (p = 0.629) and baseline BCVA (p = 0.519) did not influence recurrence. Number of injections administered to control the disease in the first episode was the only significant predictor of recurrence (Cox Proportional Hazard Ratio 2.89–3.07, 95% Confidence Interval: 1.28–7.45; p = 0.005). At 12 months, eyes requiring one injection in first episode had a recurrence rate of 12% versus 45% in eyes requiring 3 or more injections in the first episode. A mean number of 1.9 additional injections per eye was needed during re-treatment. Final BCVA in the recurrence group was similar to that of non-recurrence group (0.53 ± 0.40 versus 0.55 ± 0.36 LogMAR; p = 0.755). Baseline BCVA (p = 0.0001) was the only predictor of final visual outcome irrespective of anti-VEGF drug (p = 0.38). Conclusion Eyes requiring greater number of injections for disease control in first episode are “at risk” of early m-CNV recurrence. However, recurrence does not adversely affect visual outcome, if treated adequately.

Abstract
Background Myopic macular degeneration (MMD) is a primary cause of blindness and visual impairment in many parts of the world. A review of clinical practice guidelines (CPGs) for intervention selection are required with the increasing demand for MMD management in clinical practice as well as in national health services. Therefore, we aim to systematically review CPGs for MMD and assist the recommendations development of the Package of Eye Care Interventions (PECI) program of the World Health Organization. Methods A systematic review of CPGs published on MMD between 2010 and April 2020 was conducted. Guidelines were evaluated using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) tool. Cochrane systematic reviews were also included when the evidence from included CPGs were inadequate or contradict. Results After applying exclusion criteria and conducting the quality appraisal, two CPGs were finally included. The average of the AGREE II ratings for the identified Guidelines were 56 and 63 respectively (7 for each item). To provide further information on interventions for MMD, one Cochrane review on MMD was additionally identified and included in the study. Intravitreal anti-vascular endothelial growth factor (anti-VEGF) drugs were recommended for patients with myopic choroidal neovascularization (mCNV) as first-line therapy to improve vision and reduce central macular thickness, and ranibizumab showed significant effectiveness compared to photodynamic therapy (PDT). PDT was recommended to be performed in those resistant to the treatment by one CPG but lacked of adequate description and support. Data extracted from the Cochrane systematic reviews indicated that anti-VEGF therapy for mCNV had significant effectiveness in improving visual acuity and reducing CMT compared to PDT with moderate to low certainty of evidence. Ranibizumab and bevacizumab were considered as equally effective with moderate certainty. Conclusions The outcomes of this review suggest that high quality clinical practice guidelines for MMD management are limited. Intravitreal injection of anti-VEGF agents was recommended as an effective intervention to treat myopic CNV as the first-line treatment, while there was inadequate guidance for the application of PDT in myopic CNV management. The use of other interventions for MMD were not recommended at this time and additional evidence is called for.

Myopic choroidal neovascularization: management issues remain. ACTA BIOMEDICA SCIENTIFICA 2021.

Abstract
In the modern world, myopia continues to be one of the most common refractive errors and is considered a socially signifi cant problem, since it is a common cause of decreased vision. In connection with the growth of myopia, the risk of developing complications in the fundus increases, leading to the development of degenerative changes in the retina and an irreversible decrease in visual functions in young and middle-aged people. One of these complications is myopic choroidal neovascularization, which leads to a progressive, irreversible decrease in visual acuity and poor prognosis, and the process is often bilateral in nature. The tactics of managing patients with such complications has been determined: antiangiogenic therapy is used – intravitreal therapy with anti-VEGF drugs, which is currently the fi rst choice therapy for this pathology. But in some cases, antiangiogenic therapy is contraindicated, and the question arises about the tactics of managing such patients. The aim: to study treatment options for myopic choroidal neovascularization in patients with myopia in different situations.Material and methods. The paper presents two clinical observations of patients with mChNV, considers the tactics of their management. The patients underwent standard ophthalmological examination, optical coherence tomography (OCT) and OCT-Angio (OPTOPOL Technology, Poland).Conclusions. Women with myopia planning pregnancy need a thorough examination not only by a clinician, but also by an ophthalmologist, since it is necessary to take into account not only the degree of myopia and choose the optimal delivery method, but also to study the state of the retina for the timely diagnosis of degenerative changes in the fundus.

[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
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
In this narrative-review, we report the most recent data from the literature of anti-vascular endothelial growth factor treatment for myopic choroidal neovascularization (mCNV). Myopic CNV is the most frequent sight-threatening complication of pathologic myopia. The natural course of mCNV can result in expanding macular atrophy and /or fibrosis, leading to irreversible visual loss after 5 years. Retinal multimodal imaging is mandatory for early diagnosis and monitoring of the disease during treatment. Intravitreal anti-vascular endothelial growth factor (anti-VEGF) therapy is recommended as the first-line treatment option for mCNV. Prompt treatment of active mCNV with intravitreal anti-VEGF therapy has been demonstrated to be effective in terms of visual outcome improvements reducing the occurrence of late-stage complications.

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.

Abstract
Purpose To assess the 1-year effectiveness, safety, and treatment patterns of ranibizumab in patients with myopic choroidal neovascularization (mCNV) enrolled in the LUMINOUS study. 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.

Long-term outcomes of the intravitreal injection of ranibizumab for the treatment of choroidal neovascularization secondary to pathologic myopia. Int Ophthalmol 2019; 40:833-839. [PMID: 31788714 DOI: 10.1007/s10792-019-01247-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2019] [Accepted: 11/23/2019] [Indexed: 10/25/2022]
Abstract
PURPOSE To analyze the long-term outcomes and safety of intravitreal ranibizumab injections in myopic choroidal neovascularization (CNV). METHODS A retrospective non-randomized analysis of consecutive cases included 17 eyes from 17 patients with subfoveal myopic CNV, treated with intravitreal ranibizumab with at least 30-month follow-up. The patients received three injections monthly, followed by pro re nata regimen. Best-corrected visual acuity (BCVA) measurement, optical coherence tomography and fluorescein angiography were carried out at the baseline and at monthly intervals thereafter. RESULTS Mean follow-up period was 51 months (range 30-98 months). In 12 patients (70.6%), BCVA improved by at least 1 Snellen line, with at least 3-line improvement observed in the case of 8 eyes (47%). Mean central foveal thickness (CFT) decreased from 384.65 ± 103.3 µm at the baseline to 264 ± 86.2 µm at the last follow-up examination (p < 0.001). The final OCT examination revealed 59% (10/17) eyes with CNV-related macular atrophy. Mean number of injections over the follow-up period was 4.82 ± 2.04 per person. Nine patients (53%) required re-injection of the anti-VEGF agent; the mean number of re-injections in this group was 3.44 ± 1.34 per person (range 2-6). No significant adverse events were recorded during the study period. CONCLUSIONS Intravitreal ranibizumab is an effective and safe treatment for CNV secondary to pathologic myopia, contributing to long-term vision improvement and CFT reduction.

Abstract
PURPOSE To compare treatment results of myopic traction maculopathy according to the international photographic classification for myopic maculopathy. METHODS This was a retrospective, single-surgeon-based, observational case series of 35 consecutive eyes that underwent vitrectomy for myopic traction maculopathy. Eyes were classified into nonpathologic myopia (PM) (n = 15) and PM (n = 20) groups. Main outcome measures constituted best-corrected visual acuity (BCVA) and anatomical change. RESULTS The mean follow-up was 32.03 ± 6.85 months. Axial length correlated with myopic maculopathy category (rho = 0.6836, P < 0.001). In the total group, BCVA improved from 20/61 to 20/36 (P = 0.001). In the subgroup, BCVA improved from 20/41 to 20/22 in the non-PM group (P = 0.002), whereas from 20/82 to 20/52 in the PM group (P = 0.048). Postoperative BCVA of the PM group was inferior to that of the non-PM group (P = 0.002) and the PM group was more likely to have postoperative BCVA <20/30 (odds ratio, 17.3; 95% CI, 2.6-325.0; P = 0.012). Two cases of macular hole retinal detachment occurred after surgery in the PM group. CONCLUSION Because there are limited benefits of vitrectomy in myopic traction maculopathy accompanied by PM, careful consideration would be necessary when determining surgery. Optical coherence tomography should not be used alone in determining vitrectomy because myopic traction maculopathy can also have PM defined mainly by fundus photographs.

Abstract
A retrospective cohort study of East-Asian patients previously treated with ranibizumab for myopic choroidal neovascularization in the RADIANCE trial. Clinical charts were reviewed to assess long-term efficacy and safety. Visual acuity was sustained for additional 36 months after trial completion with few patients requiring additional treatment and no new safety concerns observed. Purpose: To evaluate long-term efficacy and safety of ranibizumab for treatment of myopic choroidal neovascularization (mCNV) in clinical practice. Methods: Noninterventional, retrospective cohort study of East-Asian patients previously treated with ranibizumab during the RADIANCE trial. Forty-one patients who completed the RADIANCE trial were followed-up for up to 48 months (post-RADIANCE observation period). Outcome measures were best-corrected visual acuity changes from baseline (assessed at RADIANCE trial initiation), mCNV recurrences, and ocular adverse events. Results: Mean visual gain from baseline best-corrected visual acuity (56.5 ± 12.1 letters) (20/80) was significant at 12 months (+14.3 ± 11.4 letters, n = 40, P < 0.0001), 24 months (+10.4 ± 22.3 letters, n = 31, P = 0.0143), 30 months (+11.0 ± 22.4 letters, n = 29, P = 0.0134), 42 months (+12.9 ± 20.9 letters, n = 25, P = 0.0051), and 48 months (+16.3 ± 18.7, n = 16, P = 0.0034). Of the 16 patients who completed 48 months of follow-up, 63% gained ≥10 letters and 13% lost ≥10 letters. Over the post-RADIANCE observation period, 83% of patients required no further treatment for mCNV, 10% experienced mCNV recurrences, and 12% experienced a nonserious ocular adverse event. Patients who required additional treatment for mCNV received a mean of 5.0 (SD 5.9, range 1.0–18.0) ranibizumab injections. Conclusion: Best-corrected visual acuity gained at the end of the RADIANCE trial was sustained over additional 36 months of follow-up. Few patients required further treatment and no new safety concerns were observed.

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
BACKGROUND Myopic choroidal neovascularization (CNV) is a common cause of central visual loss in patients with high myopia, and the most common form of CNV in younger individuals. Pharmacologic therapy is the current mainstay of treatment of these patients. METHODS Review of pharmacological treatment options for myopic CNV, which primarily involves intravitreal administration of anti-vascular endothelial growth factor (anti-VEGF) agents. RESULTS At this time, anti-VEGF therapy agents are the first-line therapy in these patients. Comparative trials have not identified any major differences in treatment outcomes between aflibercept, bevacizumab, and ranibizumab. Only ranibizumab is approved for this indication in the US. Best visual outcomes are associated with younger age, smaller lesion size, and absence of chorioretinal atrophy. CONCLUSION Anti-VEGF therapy is generally very effective in the treatment of myopic CNV.

Abstract
The authors performed a retrospective and comparative study to compare the efficacy of intravitreal aflibercept and bevacizumab for patients with myopic choroidal neovascularization (mCNV). The patients with treatment-naïve mCNV received 1 + PRN intravitreal bevacizumab from March 2008 to February 2013, while from March 2013 to July 2016 patients were treated by 1 + PRN intravitreal aflibercept, all with monthly follow-up for 12 months. Primary outcome measures included change in central foveal thickness (CFT) in 1 mm by spectral-domain optic coherence tomography, and best corrected visual acuity (BCVA) at month 12. Complications after injections were recorded. The intra-group changes in CFT and BCVA were compared with Wilcoxon signed rank test, the between-group difference compared with Wilcoxon rank sum test. Fisher's exact test was used for categorical comparison between groups. Seventy-eight eyes of 78 patients were collected. There were 42 eyes in bevacizumab group, with mean age of 53.2 ± 5.4 years and 27 female patients of them. The mean BCVA significantly improved from baseline 0.56 ± 0.35 logMAR to 0.35 ± 0.35 logMAR at Month 12 after bevacizumab treatment (p < 0.001). The mean CFT significantly decreased from baseline 315.3 ± 25.6 μm to 253.7 ± 24.4 μm at Month 12 following intravitreal bevacizumab (p < 0.001). There were 36 eyes in aflibercept group, with mean age of 52.8 ± 6.8 years and 24 female patients of them. The mean BCVA significantly improved from baseline 0.61 ± 0.47 logMAR to 0.38 ± 0.41 logMAR at Month 12 after aflibercept treatment (p < 0.001). The mean CFT significantly decreased from baseline 328.2 ± 19.8 μm to 241.8 ± 27.2 μm at Month 12 following intravitreal aflibercept (p < 0.001). The baseline demographics, lens status, axial length, refractive errors, duration of symptoms, BCVA, and CFT did not differ significantly between groups (p > 0.05). There was no significant difference between bevacizumab and aflibercept groups in BCVA and CFT from Month 1 to Month 12 (p > 0.05). Injection number of aflibercept was 2.11 ± 0.41, less than that of bevacizumab (3.23 ± 0.38) during 12-month period (p = 0.01). There were no systemic thromboembolic event, elevated intraocular pressure, retinal detachment, or infectious endophthalmitis following injections in both groups. We concluded that both aflibercept and bevacizumab can effectively treat choroidal neovascularization in high myopes. Intravitreal aflibercept had similar efficacy but less treatment number than bevacizumab for mCNV during 12-month period.

Abstract
PURPOSE To provide the clinical recommendations for the administration of intravitreal anti-vascular endothelial growth factor (VEGF) drugs especially bavacizumab for ocular vascular diseases including diabetic macular edema, neovascular age-related macular degeneration, myopic choroidal neovascularization, retinal vein occlusion and central serous chorioretinopathy. METHODS Twenty clinical questions were developed by the guideline technical committee. Relevant websites and databases were searched to find out the pertinent clinical practice guidelines to answer the questions. The technical committee provided possible answers (scenarios) according to the available evidences for each question. All scenarios along with their levels of evidence and the supported articles were sent to the experts for external review. If the experts did not agree on any of the scenarios for one particular clinical question, the technical committee reviewed all scenarios and their pertinent evidences and made the necessary decision. After that, the experts were asked to score them again. All confirmed scenarios were gathered as the final recommendations. RESULTS All the experts agreed on at least one of the scenarios. The technical committee extracted the agreed scenario for each clinical question as the final recommendation. Finally, 56 recommendations were developed for the procedure of intravitreal anti-VEGF injection and their applications in the management of ocular vascular diseases. CONCLUSION The implementation of this guideline can standardize the management of the common ocular vascular diseases by intravitreal injection of anti-VEGF agents. It can lead to better policy-making and evidence-based clinical decision by ophthalmologists and optimal evidence based eye care for patients.

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
PURPOSE This study aimed to report the outcomes of antivascular endothelial growth factor (anti-VEGF) monotherapy for choroidal neovascularization (CNVM) associated with retinochoroidal coloboma (RCC). DESIGN A retrospective case series. METHODS This was a case series of 3 eyes with CNVM associated with RCC that presented to the LV Prasad Eye Institute, Hyderabad, India, between January 2006 and January 2014. Reported data included demographics, preoperative details (symptoms, duration of symptoms, and visual acuity), treatment methods, and postoperative details (visual acuity, follow-up, and recurrence). These data were compared with 9 other cases previously reported in the literature. RESULTS Three eyes of 3 patients (2 females and 1 male) were included, with a mean age of 18.3 years (range, 2-32 years). The preoperative best corrected visual acuity ranged from 20/540 to 20/100. All 3 eyes were treated with intravitreal bevacizumab injections. The mean number of injections was 2.0 (range, 1-3) and mean duration of follow-up was 12 months (range, 4-24 months) with no recurrence. The best corrected visual acuity at the last follow-up was improved, ranging from 20/310 to 20/60. CONCLUSIONS In view of good treatment outcomes with no recurrence and a lesser number of injections, anti-VEGF monotherapy could be considered as treatment for coloboma-associated CNVM.

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

Abstract
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 The global prevalence of pathologic myopia is 0.9-3.1%, and visual impairment is found in 0.1-0.5% of European and 0.2-1.4% of Asian studies. Myopic choroidal neovascularization (mCNV) affects 5.2-11.3% of pathologic myopia patients and is a leading cause of vision impairment in the working-age population. Characteristic morphological changes and visual-acuity decrease are diagnostic features. Vascular-Endothelial-Growth-Factor (VEGF) has been identified as a trigger for pathologic neovascularization in these highly myopic patients. AREAS COVERED We cover the epidemiology, pathology and diagnostic aspects of mCNV. The history of therapeutic interventions is described, followed by an overview of current standard-of-care (SOC)-blocking VEGF using bevacizumab (off-label), ranibizumab or aflibercept and improving vision up to 13.5-14.4 letters. Despite good efficacy, an unmet medical need remains. We summarize ongoing and future developments of new drugs to treat or potentially cure mCNV. EXPERT OPINION mCNV is a major global health concern. Early detection and treatment is key for a satisfying outcome. The current SOC, VEGF inhibitors, affords good therapeutic efficacy and reasonable disease stabilization with few intravitreal treatments per year. However, the long-term prognosis is still unsatisfactory, and side-effects like chorioretinal atrophy development are of concern. Therefore, efforts should be intensified to develop more effective therapies.

Abstract
AIM To compare treatment outcomes for myopic choroidal neovascularisation (CNV) managed with verteporfin photodynamic therapy (vPDT), intravitreal antivascular endothelial growth factor (anti-VEGF, bevacizumab/ranibizumab) agents or combination thereof. METHODS Clinical data of 79 eyes with myopic CNV examined from March 2004 to July 2013 was retrospectively reviewed. Patients were managed with vPDT, intravitreal bevacizumab (1.25 mg/0.05 mL)/ranibizumab (0.5 mg/0.05 mL) or a combination of vPDT and anti-VEGF. Outcome measures included complete regression (scarring) of CNV and best-corrected visual acuity (BCVA). RESULTS Treatments provided were vPDT (n=23), anti-VEGF (n=25) (ranibizumab, n=12; bevacizumab, n=13), vPDT+anti-VEGF (n=31). Mean logMAR BCVA changed from 0.59±0.44 to 0.49±0.40 at mean follow-up of 54.63±39.46 months. Mean logMAR vision changed from 0.68±0.57, 0.54±0.48 and 0.59±0.39 at presentation to 0.59±0.53, 0.38±0.44 and 0.37±0.37 at last follow-up in PDT (p=0.4), anti-VEGF (p=0.1) and vPDT+anti-VEGF groups (p=0.0002), respectively. CNV was scarred in 64 eyes (81%) at mean 11.03±13.56 months. Most common complication was macular scar (n=64), associated with reduced (n=17) or preserved (n=47) vision. Chorioretinal atrophy attributable to vPDT was seen in five eyes (vPDT, n=3; vPDT+anti-VEGF, n=2). CONCLUSION Combination of vPDT and intravitreal anti-VEGF (ranibizumab/bevacizumab) was associated with better visual outcomes and higher rates of regression in eyes with myopic CNV as compared with monotherapy with PDT or anti-VEGF. Larger size of CNV, and high refractive error were independent risk factors for poor visual outcomes.

Abstract
Purpose The pathophysiologic pathways that govern the development of choroidal neovascularization (CNV) are complex. Patchy atrophy and lacquer cracks are known to be major anatomic risk factors for the development of myopic CNV, but they are not alone and much remains to be understood about other factors that influence development. In addition, a greater understanding of the modifiable and nonmodifiable factors that influence outcome, resolution, and recurrence after intravitreal injection of anti-vascular endothelial growth factor (VEGF) could lead to more personalized treatment algorithms that integrate parameters other than the presence of CNV itself and could help improve clinical outcomes and reduce recurrence. Methods We reviewed recently published data on risk factors for CNV and predictors of response to anti-VEGF treatments. In particular, data pertaining to age, sex, genetic predisposition, baseline visual acuity, axial length, staphyloma, lacquer cracks, atrophic lesions, choroidal thickness or choroidal thinning, characteristics of CNV such as duration, localization, and size of CNV, and treatment considerations such as choice of treatment, loading doses, and combination treatments were reviewed. Results Our analysis showed that the body of evidence is incomplete. Conclusions Additional studies are required to identify high-risk patients and to develop personalized therapeutic approaches.

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
Purpose. To investigate the correlation between aqueous and serum levels of pigment epithelium-derived factor (PEDF) and macular choroidal thickness in high myopia patients, both with and without choroidal neovascularization (CNV). Methods. Serum and aqueous levels of PEDF were measured by enzyme-linked immunosorbent assay in 36 high myopia patients (36 eyes) with no CNV (non-CNV group), 14 high myopia patients (14 eyes) with CNV (CNV group), and 42 nonmyopia patients (42 eyes) (control group). Macular choroidal thickness was measured by enhanced-depth imaging optical coherence tomography. Results. Aqueous levels of PEDF were significantly higher in CNV group compared with non-CNV (P < 0.001) and control (P < 0.001) groups. Macular choroidal thicknesses were significantly decreased in the non-CNV and CNV groups compared with the control (P < 0.001) group. A statistically significant difference (P = 0.012) was found between the CNV and non-CNV groups. There was a positive correlation between aqueous PEDF and macular choroidal thickness in the non-CNV group (P = 0.005), but no correlation with the CNV group. No correlation between serum PEDF and macular choroidal thickness was detected in the three groups. Conclusion. Variations in aqueous PEDF levels coincide with changes in macular choroidal thickness in high myopia patients with no CNV, while no such relationship exists in high myopia patients with CNV.

Abstract
Background The purpose of this study was to investigate the 12-month outcome of macular edema secondary to both chronic and new central and branch retinal vein occlusions treated with intravitreal bevacizumab in the real-life clinical setting in the UK. Methods Retrospective case notes analysis of consecutive patients with retinal vein occlusions treated with bevacizumab in 2010 to 2012. Outcome measures were visual acuity (measured with Snellen, converted into logMAR [logarithm of the minimum angle of resolution] for statistical calculation) and central retinal thickness at baseline, 4 weeks post-loading phase, and at 1 year. Results There were 56 and 100 patients with central and branch retinal vein occlusions, respectively, of whom 62% had chronic edema and received prior therapies and another 32% required additional laser treatments post-baseline bevacizumab. Baseline median visual acuity was 0.78 (interquartile range [IQR] 0.48–1.22) in the central group and 0.6 (IQR 0.3–0.78) in the branch group. In both groups, visual improvement was statistically significant from baseline compared to post-loading (P<0.001 and P=0.03, respectively), but was not significant by month 12 (P=0.058 and P=0.166, respectively); 30% improved by at least three lines and 44% improved by at least one line by month 12. Baseline median central retinal thickness was 449 μm (IQR 388–553) in the central group and 441 μm (IQR 357–501) in the branch group. However, the mean reduction in thickness was statistically significant at post-loading (P<0.001) and at the 12-month time point (P<0.001) for both groups. The average number of injections in 1 year was 4.2 in the central group and 3.3 in the branch group. Conclusion Our large real-world cohort results indicate that bevacizumab introduced to patients with either new or chronic edema due to retinal vein occlusion can result in resolution of edema and stabilization of vision in the first year.

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
Purpose The aim of this study was to evaluate the cost effectiveness of ranibizumab compared with verteporfin photodynamic therapy (vPDT) or no treatment (observation) in patients with visual impairment due to myopic choroidal neovascularization (CNV). Methods A Markov model with health states defined by best-corrected visual acuity and a 3-month cycle length was developed. It had a healthcare provider (UK National Health Service and personal social services) perspective, a lifetime time horizon, and was based on 2011 prices; future costs and health outcomes were discounted at 3.5 % per annum. Baseline characteristics were based on the phase III RADIANCE (Ranibizumab and vPDT Evaluation in Myopic CNV) study, and year 1 health-state transitions were based on this and the VIP (Verteporfin in Photodynamic Therapy) study. Extensive sensitivity analyses tested the robustness of the model. Results The lifetime cost of treating myopic CNV with ranibizumab was £12,866, whereas vPDT and observation were associated with total costs of £14,421 and £8,163, respectively. Ranibizumab treatment produced higher cumulative quality-adjusted life-years (QALYs; 12.99) than vPDT (12.60) or observation (12.45). Ranibizumab treatment was therefore dominant, with greater health gains and lower overall costs than vPDT. Ranibizumab was cost effective compared with observation, with an incremental cost-effectiveness ratio of £8,778/QALY. In the probabilistic sensitivity analysis, ranibizumab had a 100 % and 88 % probability of being cost effective compared with vPDT and observation, respectively, at a willingness-to-pay threshold of £20,000/QALY. Conclusion This study indicates that ranibizumab therapy is dominant over vPDT for the treatment of visual impairment due to CNV secondary to pathologic myopia in the UK healthcare setting and cost effective compared with observation.

Abstract
PURPOSE To develop a classification and grading system for myopic maculopathy. DESIGN Development and evaluation of a classification system for myopic maculopathy based on observational case series. METHODS A comprehensive set of myopic macular lesions was defined via literature review and through consensus meetings among retinal specialists and clinician scientists. A classification of myopic maculopathy was formulated based on fundus photographs and a modified Delphi process and consensus. Inter- and intraobserver reproducibility, assessed as agreement (%) and weighted kappa values, were evaluated. One hundred retinal photographs with myopia and myopic macular lesions were selected from case series at the High Myopia Clinic of the Tokyo Medical and Dental University, Tokyo, Japan. RESULTS We defined 5 categories of myopic maculopathy including "no myopic retinal degenerative lesion" (Category 0), "tessellated fundus" (Category 1), "diffuse chorioretinal atrophy" (Category 2), "patchy chorioretinal atrophy" (Category 3), and "macular atrophy" (Category 4). Three additional features to supplement these categories were defined as "plus" lesions, namely, lacquer cracks, myopic choroidal neovascularization, and Fuchs spot. Posterior staphyloma was considered as a further, important sign of myopic retinopathy. The intraobserver agreement was ≥85% and the corresponding weighted kappa statistic was ≥0.6 between observations. After a brief training session, interobserver kappa statistics reached the predefined satisfactory level (≥0.4), considered as above moderate agreement. CONCLUSIONS We propose a classification system for myopic maculopathy that was found to be reproducible. Applying a uniform classification in different studies will facilitate communication and comparison of findings from clinical trials and epidemiologic studies.

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.
