Intrasession repeatability of optical coherence tomography measures in active neovascular age-related macular degeneration
Objectives: To determine the repeatability of Stratus optical coherence tomography fast macular thickness map analysis in patients with active neovascular age-related macular degeneration (nAMD).Methods: Consecutive pairs of scans from 112 eyes of 112 consecutive patients with active nAMD were analyzed. The Bland[ndash]Altman coefficient of repeatability (CR) was calculated for each retinal thickness or volume measure.Results: The CR for the central 1 mm macular subfield was 59 [mu]m (18% of retinal thickness) and did not exceed 69 [mu]m in any subfield. There was much poorer repeatability for the center-point thickness (CPT) measure (CR of 78 [mu]m; 24%). However, in the subgroup of 38 patients with no Stratus software low analysis confidence message on either analysis map, the revised C
