Abstract
The Significance of Preattentive Visual Search (PAVS) in Glaucoma Methods: A novel test of PAVS, incorporating tests for flicker, motion displacement and orientation, presented on a computer monitor was developed for the detection and monitoring of glaucoma. Patients were required to detect a unique target from a background of 119 distractors. Normality was determined on the basis of patient response times measured using a two-alternative forced choice paradigm. Data were collected on 123 subjects, 41 with existing glaucoma, 41 glaucoma suspects, and 41 age-matched normals. Results: Paired samples t test indicated a statistically significant difference in PAVS response times between subjects with diagnosed glaucoma, and both glaucoma suspects and normal controls (p
