Abstract
PURPOSE To evaluate the safety and efficacy of intravitreal injections of 0.5 mg conbercept in patients with choroidal neovascularization secondary to pathological myopia (pmCNV). METHODS The 177 pmCNV patients were randomly assigned in a 3:1 ratio to receive conbercept or sham injection, respectively. The conbercept group receive conbercept intravitreal injections administered on a pro re nata (PRN) basis after 3 monthly loading doses. The sham group received three consecutive monthly sham injections and then one conbercept injection followed by PRN conbercept intravitreal injections. RESULTS At month 3, the mean BCVA for the two groups were improved by 12.0 letters (conbercept group, from 54.05 letters to 66.05 letters) and 0.6 letters (sham group, from 49.77 letters to 50.33 letters), respectively (p < 0.001). The mean central retinal thickness (CRT) at month 3 in the two groups decreased 62.0 μm (conbercept group, from 348.90 μm to 286.18 μm) and 4.4 μm (sham group, from 347.86 μm to 343.47 μm) (p < 0.001). At month 9, the mean BCVA improved by 13.3 letters in the conbercept group and 11.3 letters in the sham group. The mean CRT decreased 73.6 μm in the conbercept group and 55.9 μm in the sham group (p < 0.001). The most common ocular adverse events were associated with intravitreal injections, such as conjunctival haemorrhage and increased intraocular pressure. CONCLUSION Intravitreal injections of 0.5 mg conbercept provided improvement in visual and anatomical outcomes in pmCNV patients with low rates of ocular and nonocular safety events.

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
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.

Abstract
Purpose: To investigate the changes in intraocular cytokines after ranibizumab treatment in patients with polypoidal choroidal vasculopathy (PCV).Methods: This multicenter, prospective study enrolled patients with PCV treated with three monthly ranibizumab followed by a pro re nata regimen for 24 weeks. Best corrected visual acuity, slit lamp examination, fundus photography, and optical coherence tomography were performed every 4 weeks. Aqueous humor was collected to measure intraocular cytokines at baseline, week 8, and the time of recurrence or week 20. The association of changes in intraocular cytokines with visual acuity, central macular thickness, central choroidal thickness, area of abnormal vessels, and polyp closure was assessed.Results: This study included 25 eyes. The mean patient age was 70.3 ± 6.1 years. The vascular endothelial growth factor (VEGF) concentration decreased at week 8, but only interferon (IFN)-γ, tissue inhibitors of matrix metalloproteinases (TIMP)-2, and monocyte chemoattractant protein (MCP)-2 decreased at the time of recurrence. The recurrence interval was positively associated with the baseline epithelial-neutrophil activating peptide (ENA)-78, interleukin (IL)-17, leptin, and transforming growth factor-β1, and baseline central macular thickness was positively correlated with the baseline fibroblast growth factor-4 and IL-10. Thick central choroidal thickness was associated with a low basic fibroblast growth factor and high IFN-γ at baseline. The MCP-3 and Tie-2 levels decreased in two eyes with polyp closure.Conclusions: Ranibizumab significantly reduced intraocular VEGF concentrations and consequently improved PCV. However, the cytokines IFN-γ, TIMP-2, and MCP-2, rather than VEGF, were associated with PCV recurrence. Further studies of intraocular cytokines involved in neovascularization in PCV are needed.

Abstract
Background Myopic choroidal neovascularization (CNV) is the most common sight-threatening complication associated with high myopia. The present study evaluated the efficacy and safety of the intravitreal injection of ziv-aflibercept in patients with myopic CNV. Methods This prospective interventional study was conducted on 20 eyes of 20 patients with active myopic CNV. Twelve patients were 40 years or older. This study was performed in the Ophthalmology Department of Tanta University Eye Hospital, Tanta University, Egypt. Optical coherence tomography (OCT) was performed for all patients at baseline and monthly after injection during the 6-month follow up period. The main outcome measures were changes in BCVA and CMT. The exploratory outcome measures were CNV size, IOP and the number of injections needed in each age group during the study period. Results Patients with myopic CNV younger than 40 years needed fewer injections (2.00 ± 0.76) than patients older than 40 years (2.50 ± 1.00), with no statistical significance detected between the two groups (p-value 0.246). CNV was smaller in the younger age group (p-value 0.209), best corrected visual acuity (BCVA) improved significantly in the younger and older age groups (p-values 0.001 and 0.028, respectively), and central macular thickness (CMT) decreased significantly after 6 months, from 242.88 ± 23.83 μm to 191.13 ± 13.83 μm in the younger age group and from 251.33 ± 26.60 μm to 197.08 ± 17.64 μm in the older age group (p = 0.001). No significant correlation was found between the final BCVA and either the spherical equivalent or central macular thickness after 6 months, with p-values of 0.135 and 0.145, respectively. No significant changes in IOP were detected in either group after the intravitreal injection. Conclusion Ziv-aflibercept is a highly effective and safe drug in cases of active myopic CNV; however, a larger number of patients and a longer follow-up period are needed to confirm our results. This study was retrospectively registered at clinicaltrials.gov (ID: NCT04290195) on 26-2-2020.

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
AIM The aim of this study is to evaluate long-term efficacy of intravitreal injections of aflibercept as primary treatment for subfoveal/juxtafoveal myopic choroidal neovascularisation (CNV).METHODS Thirty-eight treatment-naive eyes of thirty-eight patients with subfoveal/juxtafoveal myopic CNV received initial intravitreal aflibercept injections and were followed for at least 18 months. Aflibercept was applied again for persistent or recurrent CNV, as required. Statistical analysis was carried out using SPSS.RESULTS Mean patient age was 45.8 years, and mean eye refractive error was -7.79 D. For the total patient group (n=38 eyes), mean logMAR best-corrected visual acuity (BCVA) significantly improved from 0.69 at baseline to 0.15 at 18 months (P<0.01). Over half of the treated eyes obtained resolution with one aflibercept injection. Patients were also grouped according to age, as <50 years (n=20 eyes) and ≥50 years (n=18 eyes). Mean BCVA improvement was significantly greater in eyes of the younger myopic CNV group, compared with those of ≥50 years (0.21 vs 0.35; P<0.05). The mean number of aflibercept injections was 1.8 for the <50 years myopic CNV group, and 3.6 for the ≥50 years myopic CNV group (P<0.001). Correlation between spherical equivalent refraction and final visual acuity reached statistical significance only for the <50 years myopic CNV group (P<0.001; Levene's correlation).CONCLUSIONS Intravitreal aflibercept provides long-term visual acuity improvement in myopic CNV. The <50 years old myopic CNV group had significantly fewer injections, with greater visual acuity improvement. Intravitreal aflibercept in myopic CNV does not require the three-injection loading phase used for aflibercept treatment of neovascular age-related macular degeneration.

Abstract
Macular degenerations represent leading causes of central blindness or low vision in developed countries. Most of these severe visual disabilities are due to age-related macular degeneration (AMD) and pathologic myopia (PM), both of which are frequently complicated by subfoveal choroidal neovascularization (CNV). Photodynamic therapy with verteporfin (PDT-V) is still employed for CNV treatment in selected cases or in combined regimen. In Caucasian patients, the common polymorphism G185T of factor XIII-A gene (FXIII-A-G185T; rs5985) has been described as predictor of poor angiographic CNV responsiveness to PDT-V. Nevertheless, the prognostic implications of this pharmacogenetic determinant on long-term visual outcome after a PDT-V regimen have not been evaluated. We retrospectively selected Caucasian patients presenting with treatment-naive CNV and receiving standardized PDT-V protocol for two years. The study population included patients affected by subfoveal CNV secondary to AMD or PM. We assessed the correlations between the polymorphic allele T of FXIII-A-G185T and: (1) total number of photodynamic treatments; and (2) change in visual acuity from baseline to the end of the follow-up period. Considering a total study population of 412 patients with neovascular AMD or PM, the carriers of 185 T-allele of FXIII-A (GT or TT genotype) received a higher number of photodynamic treatments than patients without it (GG wild-type genotype) (p < 0.01; mean number of PDT-V: 5.51 vs. 3.76, respectively). Moreover, patients with 185 T-allele of FXIII-A had a more marked worsening of visual acuity at 24 months than those with the GG-185 wild genotype (p < 0.01; mean difference in logMAR visual acuity: 0.22 vs. 0.08, respectively). The present findings show that the G185T polymorphism of the FXIII-A gene is associated with significant differences in the long-term therapeutic outcomes of patients treated with standardized PDT-V protocol. The comprehensive appraisal of both anti-thrombophilic effects due to FXIII-A G185T variant and photo-thrombotic action of PDT-V toward CNV provides several clues about the rationale of this intriguing pharmacogenetic correlation. Further investigations are warranted to outline the appropriate paradigm for guiding PDT-V utilization in the course of the combined therapeutic protocol for neovascular macular degeneration.

Background/Purpose: The purpose of this study is to share experiences diagnosing and treating choroidal neovascularization (CNV) in young patients (age ≤ 50 years) at our hospital. Methods: The study reviewed retrospective data of patients (≤ 50 years old) with CNV who received antivascular endothelial growth factor treatment (anti-VEGF) between January 2007 and August 2012 at Shin Kong Wu Ho-Su Memorial Hospital. We recorded the total number of injections, types of drugs, preoperative and final best-corrected visual acuity (BCVA), central retinal thickness (CRT) in optical coherence tomography (OCT), and total follow-up times, and then used two-tailed paired t tests to compare mean changes in BCVA and CRT on OCT. Results: The study enrolled 59 patients ≤ 50 years of age with CNV diagnosed in 67 eyes. The mean age was 36.9 ± 10.0 years (range, 8–50 years). Twenty-one patients were male and 38 patients were female. Forty-two CNV lesions were subfoveal, 19 were juxtafoveal, and five were extrafoveal. The mean total follow-up time was 18.5 ± 19.9 months (range, 0.5–71 months). Pathologic myopia was the most common cause of CNV in this study (47.8%), followed by punctate inner choroidopathy (17.9%), idiopathic CNV (16.4%), polypoidal choroidal vasculopathy (13.4%), angioid streaks (3.0%), and choroidal rupture (1.5%). After anti-VEGF treatment, the mean BCVA improved from 0.69 ± 0.61 to 0.42 ± 0.59 (p < 0.05). CRT decreased from 257.5 ± 48.2 to 210.3 ± 35.7 (p < 0.05). The mean number of injections was 1.9 ± 1.6 (range, 1–9). Conclusion: In this study we found that pathologic myopia, punctate inner choroidopathy, and idiopathic and polypoidal choroidal vasculopathy comprised the four most common causes of CNV in patients ≤ 50 years of age in Taiwan. We also revealed that anti-VEGF treatment is highly effective in the treatment of CNV in this age group.

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

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

Abstract
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.

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

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

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

Abstract
To evaluate the outcome of photodynamic therapy (PDT) and the factors influencing its outcome in patients with subfoveal choroidal neovascularization (CNV) due to pathologic myopia. Twenty-three eyes of 21 consecutive patients who received PDT for subfoveal CNV due to pathologic myopia and who were followed for >12 months were included in the study. The relationship between the factors that might affect the treatment outcome were evaluated. Mean age was 48.7 ± 16.0 years (23-74 years). Mean follow-up was 23.2 ± 7.7 months (15-41 months). Mean logMAR visual acuity was 0.85 ± 0.24 before treatment, 0.89 ± 0.37 at 12 months, and 0.92 ± 0.46 at the final visit. Mean logMAR visual acuity did not change significantly at 12 months or at the final visit (P = 0.47 and 0.36, respectively). The baseline visual acuity strongly correlated with the final visual acuity (P = 0.001). Age showed an inverse correlation with change in logMAR visual acuity at 12 months (P = 0.01). PDT prevented significant visual loss in eyes with subfoveal CNV due to pathologic myopia. Better initial visual acuity resulted in better final visual acuity. Younger age was correlated with better treatment outcome at 12 months.

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

Abstract
PURPOSE To determine the concentration of vascular endothelial growth factor (VEGF) in the aqueous humour of eyes with myopic choroidal neovascularization (mCNV). METHODS Aqueous humour samples were obtained from 21 eyes of 21 patients with mCNV and from 21 eyes of 21 patients with cataract without CNV or other ocular or systemic diseases (control group). The VEGF concentration in the aqueous humour was measured using an enzyme-linked immunosorbent assay. RESULTS The VEGF concentrations in the aqueous humour of eyes with mCNV ranged from < 20.6 to 200 pg/ml (median 35 pg/ml). The concentrations in the control group ranged from 26 to 218 pg/ml (median 100 pg/ml). The difference between the two VEGF concentrations in the aqueous humour was significant (p < 0.001, Mann--Whitney rank sum test). CONCLUSION The VEGF concentration in the aqueous humour of patients with mCNV is lower than in normal controls. VEGF might localize in or around the CNV in eyes with mCNV.

Abstract
PURPOSE The purpose of this study was to evaluate the safety and efficacy of intravitreal bevacizumab in treatment-naive patients with choroidal neovascularization (CNV) secondary to pathologic myopia over a 2-year interval. METHODS Patients diagnosed with myopic CNV who had not received previous treatment were given intravitreal injections of bevacizumab (2.5 mg/0.1 mL). All patients were retrospectively evaluated using best-corrected visual acuity (BCVA) and central macular thickness (CMT) measured with optical coherence tomography (OCT). RESULTS Twenty-six eyes of 26 patients aged 15-81 years (mean, 42.6 years) were enrolled. OCT images demonstrated that the mean CMT±standard deviation (SD) significantly changed from 270±47 μm at baseline to 228±35, 218±35, 212±25, 210±29, and 209±30 μm in the 1st, 3rd, 6th, 12th, and 24th post-treatment months, respectively (P<0.001 for all). The BCVA in logarithm of the minimum angle of resolution±SD significantly changed from 0.75±0.43 at baseline to 0.57±0.44, 0.42±0.44, 0.39±0.47, 0.41±0.44, and 0.42±0.41 in the 1st, 3rd, 6th, 12th, and 24th post-treatment months, respectively (P<0.001 for all). The mean number of injections was 1.69 (range, 1-4) within the 24-month period. The follow-up period ranged from 24 to 35 months (mean, 28 months). No other ocular or systemic adverse effects were observed. CONCLUSIONS Although the present study lacked a control group, the results in this small series of patients over the 2-year follow-up period indicate that intravitreal injection of 2.5 mg bevacizumab is effective and safe in patients with myopic CNV.

Graefes Arch Clin Exp Ophthalmol 2011; 249:1287-93. [PMID: 21484465 DOI: 10.1007/s00417-011-1654-4] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2010] [Revised: 01/04/2011] [Accepted: 02/07/2011] [Indexed: 10/18/2022] Open
Abstract
PURPOSE To compare the 1-year functional and anatomical outcomes of intravitreal bevacizumab (IVB) and photodynamic therapy (PDT) in patients with myopic choroidal neovascularization (CNV). METHODS Review of retrospectively collected data of 80 eyes in 80 patients with myopic CNV treated with standard PDT (n = 40) or IVB (1.25 mg/ 0.05 ml) (n = 40). Best-corrected visual acuity (BCVA) and central retinal thickness (CRT) measured with optical coherence tomography (OCT) were compared between the two groups at baseline, 3, 6 and 12 months. RESULTS In the IVB group, mean BCVA was +0.9 ± 0.85 logMAR at baseline. Mean BCVA was significantly better at 3 and 6 months than baseline (p = .0095 and p = .008, respectively) but not at 12 months (p = .065). In the PDT group, mean BCVA was +0.88 ± 0.45 logMAR at baseline, and improved to +0.85 ± 0.62 logMAR at 3 months and to +0.86 ± 0.44 logMAR at 6 months, which was not significantly different from baseline. Mean BCVA then decreased to +0.9 ± 0.54 logMAR at 12 months (p = .85). Mean logMAR VA was significantly better in the IVB group than in the PDT group after 3 months (p = .0043), 6 months (p = .0001) and 12 months (p = .0168). Mean CRT was significantly lower in IVB group than in PDT group at 3, 6 and 12 months (p = .008, p = .038, p = .040, respectively). Chorioretinal atrophy developed in six eyes (15%) treated with IVB and in 24 eyes (60%) treated with PDT at 12 months (p = 3.2 × 10(-5)). CONCLUSIONS Over a 12-month period, intravitreal bevacizumab seems to be superior to photodynamic therapy in controlling myopic CNV in a North-African population.

Long-term results of photodynamic therapy for choroidal neovascularization in Japanese patients with pathologic myopia. Am J Ophthalmol 2011; 151:137-147.e1. [PMID: 20970774 DOI: 10.1016/j.ajo.2010.06.046] [Citation(s) in RCA: 32] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2010] [Revised: 06/30/2010] [Accepted: 06/30/2010] [Indexed: 01/14/2023]
Abstract
OBJECTIVE To determine the results of photodynamic therapy (PDT) in highly myopic eyes with choroidal neovascularization (CNV). DESIGN Open-label, consecutive, interventional case series. METHODS Forty-eight eyes of 46 consecutive Japanese patients with a myopic CNV were studied. The eyes were treated with PDT and were followed up from 1 to 4 years. The best-corrected visual acuities (BCVAs) at the baseline and after the PDT were compared. Multivariate regression analyses were used to determine the factors that were significantly associated with the BCVA at 3 or 4 years. RESULTS The mean follow-up period was 3.2 years. Sixty-nine percent of the patients obtained angiographic closure by a single PDT treatment, and the average number of PDT treatments was 1.4. Chorioretinal atrophy developed in 61% of the eyes at 3 years and in 70% of the eyes at 4 years. The BCVA did not change significantly after the PDT. Multivariate regression analyses showed that the BCVA at 3 years was significantly correlated with the baseline BCVA and area of chorioretinal atrophy. Analyses of the 20 patients at 4 years or more showed that in 5 of 7 (71.4%) patients with juxtafoveal CNV, chorioretinal atrophy did not develop and that all had BCVA of 0.5 or better. However, in 12 of the 13 patients with a subfoveal CNV, chorioretinal atrophy developed at 4 years, and 10 of these patients had BCVA of 0.1 or worse. CONCLUSIONS In highly myopic patients, 69% obtained angiographic closure by a single PDT treatment, and recurrence was rare. These findings indicate that PDT is still a good option for treating CNVs in highly myopic patients.

Abstract
PURPOSE To compare the long-term visual and anatomic outcome of treatment with photodynamic therapy (PDT) or intravitreal bevacizumab (IVB; Avastin; Genentech Inc, South San Francisco, California, USA) for choroidal neovascularization attributable to pathologic myopia (mCNV). DESIGN An open-label, interventional case series. METHODS SETTING Multi-institutional. PATIENTS Thirty-one eyes of Japanese women who received either PDT or IVB for mCNV. Inclusion criteria were age 50 years or older, greatest linear dimension (GLD) 1200 to 3000 microm, and baseline best-corrected visual acuity (BCVA) 20/200 to 20/40. INTERVENTION PROCEDURES: Patients received either PDT or IVB (1 mg/40 microL) throughout the study, with re-treatment when necessary. MAIN OUTCOME MEASURES BCVA and visual gain/loss at 3, 6, 12, 18, and 24 months after the initial treatment. RESULTS Age, BCVA, location of CNV, refractive error, and symptom duration at baseline did not differ significantly between groups. BCVA was significantly improved at 3 to 12 months (P < .05); however, the significance was lost at 18 and 24 months in the IVB group. The PDT group showed no significant improvement within the first year, and vision slowly worsened after 12 months, becoming significantly worse at 18 and 24 months compared to baseline (P< .01). BCVA was significantly higher in the IVB group at 6 months (P< .05), and 12 months or further (P < .01). Visual gain was significantly greater in the IVB group at 6, 12, 18, and 24 months (P < .05 for 6, 18, and 24 months and P < .01 for 12 months). CONCLUSIONS These findings indicate that the effects of PDT and IVB have a different time course, and that IVB provides a significantly better BCVA than PDT for mCNV over the long-term.

Abstract
BACKGROUND To evaluate the efficacy and safety of low-fluence-rate photodynamic therapy (LFPDT) to treat choroidal neovascularisation (CNV) secondary to pathological myopia (PM). METHODS Twenty-five eyes with CNV in PM underwent LFPDT, with a standard dose of verteporfin and timing but adopting fluence and irradiance rates reduced to 25 mJ/cm2 and 300 mW/cm2, respectively. Best corrected visual acuity (BCVA) was measured and biomicroscopy and fluorescein angiography (FA) were evaluated. Particular attention was paid to choroidal hypoperfusion, and to changes (depigmentation/atrophy) at the RPE level in areas exposed to laser light. RESULTS After a mean follow-up of 13.4+/-2.46 months (range: 12-21), and 1.37+/-0.66 treatments (range: 1-3), BCVA was stable in 29 (91%) eyes. Two (6%) patients gained more than three lines and one (3%) eye lost more than three lines. Mean greatest linear dimension did not change significantly (p=0.08) at the end of follow-up. RPE depigmentation was present in six eyes (18%) and no patient showed RPE atrophy. CONCLUSIONS LFPDT is effective and safe for CNV secondary to PM treatment, stabilizing visual acuity and lesion size and determining only mild RPE changes. Further controlled studies are needed to demonstrate the long-term efficacy and safety of this treatment option.

Abstract
PURPOSE To compare the visual outcomes of intravitreal bevacizumab (Avastin; Genentech Inc, South San Franciso, California, USA) and sub-Tenon triamcinolone acetonide (TA) for choroidal neovascularization attributable to pathologic myopia (mCNV). DESIGN Retrospective, comparative, interventional case series. METHODS Fifty-four consecutive eyes of 53 patients with mCNV treated with either sub-Tenon TA or intravitreal bevacizumab in an institutional setting were included. Twenty eyes were treated with sub-Tenon TA and 34 eyes were treated with intravitreal bevacizumab. The main outcome measures included best-corrected visual acuity (BCVA) 12 months after the initial injection and logarithm of the minimum angle of resolution gain from baseline compared with analysis of covariance (ANCOVA). RESULTS At 12 months, the BCVA improved by 1.9 lines in the intravitreal bevacizumab group and worsened by 0.3 lines in the sub-Tenon TA group. Thus, the intravitreal bevacizumab group had significantly greater visual improvement than the sub-Tenon TA group (P < .01). Statistical analysis (ANCOVA) revealed that age (P = .01), pretreatment BCVA (P < .01), and the treatment choice (intravitreal bevacizumab or sub-Tenon TA; P < .01) correlated significantly with the BCVA and the BCVA gain at 12 months. The refractive error was of borderline significance (P = .06). CONCLUSIONS Although this study is limited because of its retrospective nature, intravitreal bevacizumab seems to result in a more favorable visual outcome than sub-Tenon TA in the treatment of mCNV. Patient age, the BCVA before treatment, and the refractive error must be considered to initiate the treatment.

Abstract
CONTEXT In India, refractive errors are a major cause of treatable blindness. Population surveys in southern India have shown prevalence of high myopia to be 4.32-4.54%. Photodynamic therapy (PDT) for choroidal neovascularization (CNV) caused by pathologic myopia is beneficial. AIMS To report the 24 months outcome of PDT with verteporfin for subfoveal CNV caused by pathologic myopia in Indian eyes. SETTINGS AND DESIGN Prospective case series. MATERIALS AND METHODS Review of prospectively collected data of Indian patients with pathologic myopia and subfoveal CNV treated with verteporfin therapy between 2001 and 2005 using standard regimen for PDT. STATISTICAL ANALYSIS USED Wilcoxon signed rank test was used to see the difference in the mean letter acuity at intervals compared to baseline. Kaplan Meier Survival analysis was done to estimate the success rate of verteporfin therapy for CNV caused by pathologic myopia. RESULTS Fifteen patients (15 eyes) treated with standard fluence PDT and who had completed 24 months follow-up were analyzed. The mean spherical equivalent was -13.36 +/- 5.88 diopter. Five out of 15 eyes in six months, three out of 15 eyes at 12 months and four eyes out of 15 at 24 months had improved vision by > 10 letters. The mean number of treatment session was 2.2 in two years. CONCLUSIONS PDT with verteporfin for subfoveal CNV caused by pathologic myopia in Indian eyes is effective.

Abstract
PURPOSE To evaluate the visual outcome of patients with subfoveal choroidal neovascularization (CNV) secondary to pathologic myopia treated with verteporfin photodynamic therapy (PDT-V) and to verify the predictive role of visual and angiographic parameters. METHODS This is a retrospective, interventional, consecutive case series study of subjects with subfoveal CNV secondary to pathologic myopia. All patients received PDT-V according to VIP guidelines. A complete ophthalmologic evaluation was performed on all patients and included best-corrected visual acuity (BCVA), fundus examination, and fluorescein angiography (FA, IMAGEnet System, Topcon Corp., Japan). CNV size (mm2) was directly measured on the early phase of the angiogram using the software included with the IMAGEnet package. All checks were scheduled at 3-month intervals for a period of 1 year. A review of medical and angiographic records was performed and assessed throughout a 12-month follow-up period. RESULTS A total of 62 patients (62 eyes) were examined. Best-corrected visual acuity (BCVA) moderately decreased without reaching a statistically noticeable level throughout the followup; reduction in lesion size reached a significant level at the second checkup. A significant correlation between higher baseline BCVA and better final visual outcome was detected. CONCLUSIONS Standardized PDT-V minimizes central vision deterioration in patients with CNV secondary to pathologic myopia. Better BCVA at presentation represents a good predictive sign.

Abstract
PURPOSE To assess the potential effect of intravitreal bevacizumab (IVB) (Avastin) on retinal function and anatomic recovery in eyes with choroidal neovascularization attributable to pathological myopia (mCNV). DESIGN Retrospective case series. METHODS setting: Institutional. patient population: Sixty-three eyes of 63 patients were treated with IVB for mCNV. intervention procedure: 1 mg of bevacizumab was injected into the vitreous via the pars plana. IVB was repeated after two to three months if there was fluorescein leakage in fluorescein angiogram (FA), apparent subretinal fluid in optical coherence tomography (OCT) persisted, or both. main outcome measurement: Best-corrected visual acuity (BCVA) and CNV size measured on FA. RESULTS IVB was performed one to six times during the first 12 months (mean, 2.4 +/- 1.4 times). The size of the mCNV decreased and the BCVA improved significantly (P < .01 for both comparisons). The BCVA improved more than three lines in 25 eyes (40%), worsened more than three lines in three eyes (5%), and was unchanged in 35 (56%) eyes 12 months after. Fluorescein leakage from the mCNV ceased in 30 eyes (48%), diminished in 28 (44%), and was unchanged in five (8%) eyes. Stepwise analysis showed that the number of IVB (P < .01), macular atrophy associated with mCNV (P < .05), and myopic atrophy (P < .05) were significant predictive factors for BCVA at 12 months. CONCLUSIONS Although the current study lacked a control group, IVB seems to be an effective treatment for mCNV after a long-term. The absence of chorioretinal atrophy and that of recurrence and persistency of mCNV are positive predictive factors.

Abstract
PURPOSE To clarify the characteristics of choroidal neovascularization (CNV) due to myopic CNV (mCNV) and the relation to lacquer crack (LC) formation. PATIENTS AND METHODS Thirty-seven eyes with mCNV underwent fluorescein angiography (FA) and indocyanine green angiography (ICGA) using Heidelberg Retina Angiograph 2 (HRA2; Heidelberg, Germany). mCNV was detected by FA and ICGA; LCs were detected by late-phase ICGA. RESULTS Thirty-five eyes (95%) had classic mCNV, and 2 (5%) had occult CNV. LCs developed in 35 (95%) of 37 eyes. In 33 eyes (94%), classic mCNV originated from LCs; the 2 other eyes had small horizontal dotlike LCs, but mCNV originated from the adjacent area of LC. No occult CNV was associated with LCs. Two morphologic types of LCs were observed, linear (21 eyes [62%]) and stellate (12 eyes [32%]) from which mCNV originated, with no significant differences in parameters between the two types. Classic mCNV demonstrated well-delineated hyperfluorescence by late-phase ICGA in 10 eyes (29%), which was significantly correlated with absence of a dark rim (P = 0.022). CONCLUSIONS ICGA using HRA2 provides more detailed information on mCNV and LCs. LC formation is essential for classic mCNV to develop. Morphologic variations of LCs were not different clinically. Late-phase hyperfluorescence, probably due to the absence of pigment epithelium around the mCNV, may represent its activity.

Abstract
PURPOSE To examine the effects of photodynamic therapy (PDT) with verteporfin on subfoveal or juxtafoveal choroidal neovascularization (CNV) secondary to pathologic myopia in Japanese patients and to compare the visual outcomes of PDT-treated patients with that of age-matched and visual acuity-matched untreated controls. DESIGN Prospective, open-label, consecutive, interventional case series. METHODS We prospectively followed up 43 eyes of 42 consecutive patients with pathologic myopia (>6 diopters or axial length>26.5 mm) who received PDT for myopic CNV. In addition, the visual outcomes of these patients who were followed up for more than one year were compared with those of age- and initial visual acuity-matched untreated controls. RESULTS The average follow-up was 15.0+/-7.0 months. Patients received an average of 1.40+/-0.73 treatments during follow-up, and 30 eyes (69.8%) required only one treatment. The best-corrected visual acuity (BCVA) improved by more than two Snellen lines in seven eyes (16.3%), decreased in six eyes (14.0%), and remained stable in 30 eyes (69.7%). In three eyes with a juxtafoveal CNV, CNV could not be detected ophthalmoscopically or angiographically after PDT. Statistical analysis showed that the PDT-treated patients had significantly better visual acuity at one year after PDT than the age- and initial BCVA-matched untreated controls. CONCLUSIONS These results indicate that PDT was beneficial for maintaining vision in Japanese patients with myopic CNV. The visual outcome after PDT was better than the natural course of the disease as determined from untreated controls. The effect on chorioretinal atrophy around CNV should be investigated with a long-term study.

Abstract
PURPOSE To evaluate the safety and efficacy of intravitreal bevacizumab in the treatment of choroidal neovascularization (CNV) secondary to pathologic myopia (PM). DESIGN Prospective, consecutive, nonrandomized, interventional case series. PARTICIPANTS Twenty-two eyes of 22 patients with CNV secondary to PM. METHODS Consecutive patients with subfoveal or juxtafoveal CNV secondary to PM were recruited prospectively to receive an initial course of 3 monthly intravitreal injections of bevacizumab. Three additional monthly injections were performed in eyes with persistent CNV leakage after 3 months. Patients were followed up for 6 months, and the best-corrected visual acuity (BCVA), changes in fluorescein angiography, and optical coherence tomography (OCT) results were assessed. MAIN OUTCOME MEASURES Changes in BCVA, angiographic closure, and OCT central foveal thickness (CFT) at the 6-month follow-up. RESULTS The mean+/-standard deviation (SD) spherical equivalent refractive error of the 22 eyes was -10.3+/-3.7 D (range, -6.0D to -18.0D). All patients completed follow-up at 6 months. Twenty (90.9%) eyes had angiographic closure after 3 monthly injections of intravitreal bevacizumab, and 2 (9.1%) eyes required further treatment up to 6 months. The mean+/-SD logarithm of the minimum angle of resolution (logMAR) BCVA at baseline was 0.60+/-0.18 (Snellen equivalent, 20/80). At 1 and 6 months, the mean+/-SD logMAR BCVA improved significantly to 0.43 (Snellen equivalent, 20/53; P = 0.003) and 0.35 (Snellen equivalent, 20/45; P<0.001), respectively. The mean lines of improvements at 1 and 6 month compared with baseline were 1.7 and 2.6 lines, respectively. Fifteen (68.2%) eyes had an improvement of 2 or more lines at 6 months. The OCT results also showed significant reduction in CFT after treatment. No ocular or systemic complications were noted after intravitreal injections. CONCLUSIONS The 6-month outcomes suggest intravitreal bevacizumab to be a promising treatment method for CNV secondary to PM, resulting in both visual and anatomic improvements. Treatment resulted in complete absence of angiographic leakage in 90.9% of eyes at 3 months. Further studies to evaluate the safety, efficacy, and optimal treatment regimen are justified.

Abstract
PURPOSE To examine the efficacy of photodynamic therapy with verteporfin (VPDT) for treatment of subfoveal choroidal neovascularization (CNV) in patients with pathologic myopia. METHODS In a prospective study, adult patients (18 years of age or older) with new onset subfoveal CNV were treated in two tertiary centers with the standard protocol of VPDT. Snellen best-corrected visual acuity was measured at baseline and at 1 month, 3 months, 6 months, 12 months, 15 months, 18 months, and 24 months after VPDT. Stratified analyses for single and multiple treatments and different age groups were performed by paired t-tests, and the results were compared with baseline findings. RESULTS Thirty-three patients with single VPDT and 13 patients with multiple treatments were enrolled for analysis. Significant improvement in measurement of visual acuity was found after 24 months of follow-up for the group with single therapy. For patients receiving multiple treatments, an improving trend was not as clear. In prognosis analysis by age groups in the single-treatment group, the younger group had better mean visual acuity at the end of the 24-month study period than the older group. Improvement was much more evident in the younger group, although it was not statistically significant at every follow-up time point. CONCLUSION In patients with response to single VPDT, visual acuity significantly improved over a 2-year period. In patients receiving multiple treatments, improvement was not as distinctive, suggesting alternative treatment options might be relevant for this subgroup.

Abstract
PURPOSE To evaluate the visual outcome of photodynamic therapy with verteporfin in patients with subfoveal choroidal neovascularization (CNV) caused by pathologic myopia. METHODS Retrospective and noncomparative analysis of 42 patients with CNV secondary to pathologic myopia recruited between September 2001 and 2003, who were treated with a standard regimen of photodynamic therapy with verteporfin. RESULTS Forty-two patients were followed up for 12 months; 15 out of 42 completed 24 months of follow-up. Initial visual acuity ranged from 1/10 to 5/10 with a mean of 1.6/10. Twenty-five (56.7%) eyes had stable or improved visual acuity at 12 months with a mean of 2.5/10. In the group of patients who completed 24 months of follow-up, six eyes (39.9%) had stable or improved visual acuity with a mean of 1.6/10 at 1 year and 1.25/10 at 2 years. The average photodynamic therapy treatment required in 1 and 2 years were 1.5 and 2.1, respectively, and they are less than those reported by the Verteporfin in Photodynamic Therapy (VIP) study. CONCLUSION Photodynamic therapy with verteporfin for subfoveal choroidal neovascularization caused by pathologic myopia maintained a visual benefit at 1 and 2 years.

Abstract
PURPOSE To assess the safety and effectiveness of photodynamic therapy (PDT) with verteporfin for subfoveal choroidal neovascularization (CNV) secondary to pathologic myopia (PM). METHODS Sixty-two patients (62 eyes) with PM underwent PDT according to the guidelines of the Verteporfin in Photodynamic Therapy Study. Clinical evaluations performed at all study visits included measurement of best-corrected Snellen visual acuity, slit-lamp biomicroscopy, and fundus fluorescein angiography. Patients were followed up at 1 month and 3 months after treatment and thereafter at 3-month intervals. RESULTS The final visual acuity of the study patients, after a median follow-up of 31 months, improved by >or=1 Snellen lines in 8 patients (13%), deteriorated in 20 (32%), and remained stable in 34 (55%). The baseline visual acuity was similar in the various study groups. The final mean visual acuity in group A (55 years of age or younger) was 20/80 and significantly (P=0.006) better than that (20/138) in group B (older than 55 years of age). The mean final visual acuity in eyes with higher refractive error at baseline (greater than -17 diopters) was significantly better (P=0.014) than that in eyes with lower refractive error (-6 to -10 diopters). CNV size did not affect visual outcomes. CONCLUSION PDT preserves vision in patients with CNV associated with PM. Younger patients and eyes with higher refractive error appear more likely to benefit from PDT with verteporfin.

Abstract
Purpose To determine the influence of clinical features and Indocyanine green (ICG) angiographic features on the visual outcome of patients with myopic sub-foveal choroidal neovascularization (CNV) who received photodynamic therapy (PDT). Methods Thirty-six consecutive patients (39 eyes) with myopic CNV who were followed up for more than one year after PDT were enrolled in this study. Clinical features included age, gender, refractive error, great linear dimension, and subretinal hemorrhage. ICG features included the lesion size, lacquer cracks, hypofluorescence surrounding the CNV (dark rim), peripapillary atrophy size, and visible prominent choroidal veins under the macula. Linear regression analysis was performed using the change in visual acuity (ΔlogMAR) as the dependent variable and the above factors as independent variables. Results At one-year follow-up after PDT, a younger age (p=0.002) and the presence of a dark rim (p=0.002) were significantly correlated with an improvement of visual acuity (decrement in logMAR) after PDT. Other factors had no significant influence on changes in visual acuity. Conclusions Younger patients and patients with a dark rim on ICG angiography had a higher chance of visual improvement after PDT in myopic CNV.
