1. Ability of Stratus OCT to Detect Progressive Retinal Never Fiber Layer Atrophy in Glaucoma

    PURPOSE. To evaluate the ability of Stratus optical coherence tomography (OCT) to detect progressive glaucomatous retinal nerve fiber layer (RNFL) atrophy observed using red-free RNFL photography. METHODS. Intersession test-retest variability of each clock hour, quadrant, and average RNFL thickness was determined using 53 control subjects. The sensitivity and specificity of OCT for identification of progressive RNFL atrophy were tested on subjects in whom this condition was clearly observed in red-free RNFL photographs (n=27) and in another control group (n=62) using criteria derived from test-retest variability. RESULTS. The sensitivity of Stratus OCT RNFL measurement ranged from 14.8% (for ...
