PURPOSE: The purpose of this study was to estimate the optimal size of visual field test for detecting longitudinal changes in retinitis pigmentosa (RP) by dividing the visual field. METHODS: We reviewed the results of 10° static visual field tests in 19 eyes of 19 RP patients. Sixty-eight numeric value points were divided into two area types: concentric areas (A1, A1-2, A1-3, A1-4, A1-5, A1-6) and circular areas (A1, A2, A3, A4, A5, A6). Serial values of mean sensitivity in each area of each patient were analyzed by linear regression. RESULTS: Analysis of the concentric areas showed that 10 of 19 eyes had the best R (2) value in the most central area, A1. Analysis of circular areas showed that 7 of 19 eyes had the steepest slope of decline in A1. The inner-segment/outer-segment (IS/OS) line was significantly shorter in eyes with low variability and evident disease progression in the inner areas than the ones in the outer areas. CONCLUSIONS: The optimal size of monitoring RP progression was different in each case and may depend on the remaining morphology of the outer retina.
