Ranibizumab for subfoveal choroidal neovascularisation associated with Stargardt disease

INTRODUCTION: To describe the clinical outcomes of intravitreal ranibizumab treatment for subfoveal choroidal neovascularisation (CNV) associated with Stargardt disease. METHODS: Prospective, interventional, case series. All patients underwent intravitreal ranibizumab injections following a pro re nata regimen with monthly examination, over a 24-month follow-up. RESULTS: Three eyes were included in the study. Best corrected visual acuity changed from 0.47±0.06 (mean±SD) at baseline to 0.90±0.17 LogMAR at the end of the 24-month follow-up. Overall, a mean number of 11 ranibizumab injections were administered in 24 months. Significant atrophic growth was detected in all cases, with the mean atrophy area increasing from 2.34±2.60 mm(2) (mean±SD) at baseline to 4.23±3.31 mm(2) at the end of the follow-up. CONCLUSIONS: Ranibizumab treatment can stop the CNV progression, but cannot ensure a significant visual improvement. Macular atrophy tends to significantly enlarge under ranibizumab treatment over the follow-up.
