Abstract
PURPOSE: To determine interobserver agreement for classifying choroidal neovascular membranes in age-related macular degeneration. METHODS: Six fluorescein angiograms of choroidal neovascular membranes were interpreted by 21 retina specialists. Reliability was measured by percent agreement and kappa coefficient. RESULTS: Interobserver agreement of membrane types ranged from perfect concordance for a small, classic membrane to near-random classification for a complex pattern. Mean kappa coefficient was.64. Interobserver agreement of membrane size was most variable for intermediate size lesions (mean kappa coefficient =.40). CONCLUSION: Fluorescein angiographic interpretation of choroidal neovascular membrane type and size can vary considerably. Interobserver agreement is better for membrane type than for membrane size.
