Worse-than-usual visual fields measured in retinitis pigmentosa related to episodically decreased general health

Research output: Contribution to journalArticle

Abstract

Background/aims: We examined whether retinitis pigmentosa (RP) subjects' worse-than-usual vision measures were related to episodic changes in psychosocial factors and/or general health. Methods: In a prospective, cohort study, 37 RP subjects self-administered personal computer (PC)-based visual acuity (VA), contrast sensitivity (CS) and visual field (VF) tests at home twice a week, for 16 sessions in 2-3 months. Subjects rated their general health prior to each vision test session, and completed the Perceived Stress Scale, Positive and Negative Affect Schedules, and Epworth and Stanford Sleepiness Scales immediately after each session. Results: Nine subjects with reduced mean VA >0.5 log minimal angle of resolution (logMAR) on average had statistically significant 26% more sessions with measured deviations ≥0.1 logMAR from their mean (95% CI 20% to 32%; p
