Comparison of stereo disc photographs and alternation flicker using a novel matching technology for detecting glaucoma progression.

Background And Objective: To compare agreement of automated alternation flicker and serial stereophotograph inspection for detection of progressive glaucoma.

Patients And Methods: Serial photographs of patients with glaucoma with at least 36 months of follow-up and perimetry every 4 months were assessed by four graders using predefined criteria with both flicker and stereophotography. The main outcome measure was progressive neuroretinal rim deterioration as identified by each technique.
