| Popis: | 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.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.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.The optimal size of monitoring RP progression was different in each case and may depend on the remaining morphology of the outer retina. |
