Abstract

Background: Photo stress recovery time is the time it takes for the macula to come back to its normal function level after exposure to a strong light source. Early diagnosis is well known to be important for effective diabetic retinopathy treatment. In recent years, the focus has been on considering macular recovery after glare as a parameter that is altered not only in manifest retinopathy, but also in the preclinical stage.

Method: A cross-sectional study was conducted at ASG Eye Hospital, Nepal. The study population consisted normal, diabetic and diabetic retinopathy patients. The photo stress test was performed on each patient. Statistical analysis was performed using SPSS for windows.

Result: Of total 90 subjects, the mean photo stress recovery time (PSRT) of normal patients on right eye and left eye were 7.46 ± 1.87 and 7.5 ± 1.54 sec respectively, mean PSRT of diabetic patients on right eye and left eye were 14.03 ± 2.39 and 14 ± 2.32 sec respectively and mean PSRT of diabetic retinopathy patients on right eye and left eye were 55.83 ± 8.26, 57.46 ± 7.76 sec respectively. PSRT obtained from the 3 groups of subjects was statistically different (p < 0.001).

Conclusion: PSRT values depend upon the clinical status of the retina. These findings highlight the need and efficacy of simple technique which can be very useful to anticipate diabetic retinopathy from diabetic patients.
