PURPOSE: To evaluate different therapies for choroidal neovascularization (CNV) due to angioid streaks (AS). METHODS: Studies were identified by a systematic literature search and were included in the analysis based on predefined criteria. Primary outcome measure was change in best-corrected visual acuity (BCVA). RESULTS: Fifty-four relevant studies were identified and included mostly uncontrolled case series. No randomized controlled trials were available. Treatment with vascular endothelial growth factor inhibitors improved or stabilized BCVA in all case series. Photodynamic therapy slowed down disease progression with stabilization or decrease of BCVA. Individual BCVA and follow-up data for each treated eye were reported in >160 cases for both treatments, vascular endothelial growth factor inhibitors and photodynamic therapy. In a pooled analysis of those studies, the difference of mean change in BCVA between both treatment groups was estimated as approximately 6 lines (0.59 logMAR [95% confidence interval, 0.38-0.8; P < 0.0001]). A better baseline BCVA was associated with a better BCVA outcome (P < 0.0001). Laser photocoagulation yielded comparable results as photodynamic therapy but application was mostly restricted to extrafoveal lesions, was complicated by frequent recurrences, and led to more retinal damage with subsequent absolute scotomas. Combination therapies seem to be not superior to monotherapy. CONCLUSION: Intravitreal vascular endothelial growth factor inhibitors are currently the most effective treatment of CNV due to angioid streaks. Copyright © Ophthalmic Communications Society, Inc.
