Threshold Levels of Visual Field and Acuity Loss Related to Significant Decreases in the Quality of Life and Emotional States of Patients with Retinitis Pigmentosa

Abstract

This work determines that, for RP patients, a significant QOL and emotional state deterioration correlates with a residual VF diameter below 20° and a VA lower than 0.3. It introduces, for the first time, thresholds to be used in visual restoration or visual preservation therapies to improve QOL of RP patients.
