Aflibercept as primary treatment for myopic choroidal neovascularisation: a retrospective study.

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.

Project description: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??m to 191.13?±?13.83??m in the younger age group and from 251.33?±?26.60??m to 197.08?±?17.64??m 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.

Project description:ObjectivesTo evaluate incidence, predictors, and re-treatment outcome of recurrent myopic choroidal neovascularization (m-CNV).MethodsRetrospective 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.ResultsOverall, 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).ConclusionEyes 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.
