BACKGROUND AND OBJECTIVE: To examine a new highresolution kinetic mapping meth od for scotoma in age-related macular degeneration. PATIENTS AND METHODS: A com puter based program for kinetic visual field mapping was tested in 10 healthy su bjects and 14 patients with age-related macular degeneration and fixed preferre d retinal locus. The stimulus was presented using a back projector on a screen l ocated 40 cm from the subject. The findings were then compared with static resul ts. RESULTS:Control group mapping revealed good congruency with the anatomic bli nd spot. Mapping of the 14 patients with age-related macular degeneration was r apid and revealed good accuracy. The average deviation of the mapping border from the a natomic scotoma border was no more than 3.1%of the scotoma radius. Static mappi ng of 7 of the patients with age-related macular degeneration was longer and re vealed lower accuracy. CONCLUSIONS: The proposed method is more rapid, accurate, and consistent than static mapping. It allows accurate mapping of central scoto ma with suprathreshold stimulus, and may be used in the future for detecting the early stages of age-related macular degeneration using subthreshold stimulus.
