摘要
To evaluate the clinical characteristics, multimodal imaging features, and long-term treatment outcomes of eyes with neovascular age-related macular degeneration (nAMD) and bacillary layer detachment (BALAD) treated with intravitreal anti-VEGF therapy.Retrospective, longitudinal, case series.Treatment-naive patients with nAMD (n = 30) showing BALAD on OCT and undergoing anti-VEGF therapy.Clinical records and multimodal imaging results of up to 4 years after diagnosis were reviewed.Best-corrected visual acuity (BCVA) values were compared over time. The cumulative risk of and risk factors for subretinal fibrosis were assessed using Cox regression analyses, and adjusted hazard ratio (aHR) was computed.Thirty eyes of 30 patients were included. Macular neovascularization (MNV) subtypes were distributed as follows: type 1, 63%; type 2, 27%; mixed type 1 and 2, 3%; type 3, 3%; aneurysmal type 1, 3%. The BCVA significantly improved after anti-VEGF loading phase (Snellen equivalent, from 20 of 118 to 20 of 71, P = 0.03), but it returned to the baseline levels at 4 years (Snellen equivalent, 20 of 103, P = 0.6). The cumulative risk of subretinal fibrosis was 77% at 4 years. The risk factors associated with subretinal fibrosis included hemorrhagic BALAD (aHR, 2.02; 95% confidence interval [CI] 1.54-3.22; P < 0.01) and the presence of subretinal hyperreflective material (aHR, 1.83; 95% CI 1.35-3.14; P < 0.01).BALAD was found in association with all types of MNV in patients with nAMD. Long-term observation revealed poor functional outcomes related to the high risk of subretinal fibrosis.
