Abstract:
PURPOSE: In this study, we identify risk factors that predict the progression of acquired vitelliform lesions (AVLs) over time. DESIGN: Retrospective cohort study. SUBJECTS: One hundred sixty-three eyes of 132 patients with a diagnosis of intermediate age-related macular degeneration (iAMD) with AVL. METHODS: This retrospective study evaluated consecutive eyes with AMD from a retina clinic population and included 1181 patients and 2362 eyes. After excluding cases with associated geographic atrophy, macular neovascularization (MNV), vitreomacular traction, and those with <2 years of follow-up data, the final analysis cohort consisted of 163 eyes (132 patients) with ≥1 AVL. The first available visit in which an AVL was evident was considered the baseline visit, and follow-up data were collected from a visit 2 years (± 3 months) later. Progression outcomes at the follow-up visit were classified into 6 categories: resorbed, collapsed, MNV, stable, increasing, and decreasing. Subsequently, we analyzed the baseline characteristics for each category and calculated odds ratios (ORs) to predict these various outcomes. MAIN OUTCOME MEASURES: The study focused on identifying predictive factors influencing the evolution of AVL in iAMD eyes. RESULTS: In total, 163 eyes with AVL had follow-up data at 2 years. The collapsed group demonstrated a significantly greater baseline AVL height and width compared with other groups (P < 0.001). With regard to qualitative parameters, subretinal drusenoid deposits (SDDs) and intraretinal hyperreflective foci (IHRF) at the eye level, AVL located over drusen, and IHRF and external limiting membrane disruption over AVL were significantly more prevalent in the collapsed group compared with other groups (P < 0.05 for all comparisons). Odds ratios for progressing to atrophy after 2 years of follow-up, compared with the resorbed group, were significant for SDD (OR, 2.82; P = 0.048) and AVL height (OR, 1.016; P = 0.006). CONCLUSIONS: The presence of SDDs and greater AVL height significantly increases the risk of developing atrophy at the location of AVL after 2 years of follow-up. These findings may be of value in risk prognostication and defining patient populations for inclusion in future early intervention trials aimed at preventing progression to atrophy.
