Visual acuity and 10 degrees automated static perimetry in eyes with retinitis pigmentosa.

Purpose: In a previous study we demonstrated that the progression of the disease retinitis pigmentosa (RP) can be readily monitored by the mean deviation (MD) measured by Humphrey central 10-2 perimetry, which assesses the sensitivity distribution in the macular area in eyes affected by RP. In the present study, we investigated whether the 10 degrees perimetric results could predict the time of declining visual acuity in eyes with RP in a cross-sectional study.

Methods: Humphrey 10-2 perimetry results and visual acuity were studied in the right eyes of 69 patients with typical RP.
