Purpose: The aim of this study was to determine the photostress recovery time (PSRT) of subjects with posterior segment ocular anomalies such as dry AMD, diabetic retinopathy, hypertensive retinopathy, and glaucoma.

Methods: This hospital-based study was carried out and PSRT evaluated for the fellow eyes of randomly selected 200 subjects. After a 10-second-bleaching of the retina, the subjects were directed to read from the line above best visual acuity (VA). Time taken to read the VA line was recorded. The data was presented and analyzed in table and the hypotheses tested at a given level of significance. Using Greenhouse-Geisser correction and Sphericity Assumed (0.000 < 0.05), observations were assessed for different ages and sexes.

Results: PSRT increased significantly in the above mentioned posterior segment ocular anomalies compared to the controls. Hence photostress recovery time test is recommended for diabetic retinopathy, hypertensive retinopathy, glaucoma and dry age related macular degeneration patients.

Conclusion: These findings show that PSRT increases in subjects with glaucoma, ARMD, hypertensive and diabetic retinopathy, mostly in older patients.
