BACKGROUND AND OBJECTIVE: To quantitatively evaluate the change in pigment epithelial detachment (PED) morphology on spectral-domain optical coherence tomography (SD-OCT) 18 months after the transition to intravitreal aflibercept in patients with neovascular age-related macular degeneration (AMD) with PED recalcitrant to monthly intravitreal bevacizumab or ranibizumab.
PATIENTS AND METHODS: Retrospective case series examining patients with neovascular AMD who had a persistent fibrovascular or serous PED on SD-OCT. PED volume was calculated by manually outlining the PED on individual OCT slices of the raster scan and multiplying by the pixel dimensions.
RESULTS: Eleven eyes of 10 patients who had received an average of 25.7 ± 20.1 (range: 6 to 70) prior bevacizumab or ranibizumab injections over a period of 26.6 ± 19.8 months (range: 4 to 63) were included. PED volume decreased with aflibercept from 0.687 ± 0.837 mm(3) to 0.562 ± 0.705 mm(3) (P = .02), a decrease of 19% ± 12.27%.
CONCLUSION: After 18 months of aflibercept, recalcitrant PED volumes were reduced by 19% while preserving visual acuity in eyes with neovascular AMD.
