The Moorfields AMD database report 2 - fellow eye involvement with neovascular age-related macular degeneration

Background/Aims: Neovascular age-related macular degeneration (nAMD) is frequently bilateral, and previous reports on ‘fellow eyes’’ have assumed sequential treatment after a period of treatment of the first eye only. The aim of our study was to analyse baseline characteristics and visual acuity (VA) outcomes of fellow eye involvement with nAMD, specifically differentiating between sequential and non-sequential (due to macular scarring in the first eye) anti-vascular endothelial growth factor treatment and timelines for fellow eye involvement.

Methods: Retrospective, electronic medical record database study of the Moorfields AMD database of 6265 patients /120,286 single entries with data extracted between October 21, 2008 and August 9, 2018. The dataset for analysis consisted of 1180 sequential, 807 nonsequential, and 3410 unilateral eyes.

Results: Mean VA (Early Treatment Diabetic Retinopathy Study letters±SD) of sequentially treated fellow eyes at baseline was significantly high...
