The photostress recovery test (PSRT), depends on resynthesis of visual pigments and measures the time to recover after bleaching due to light exposure. Abnormal recovery times in retinal diseases or toxicity suggests that the pathology in these conditions involves the outer layer of the retina or the pigment epithelium. Aim: 1) To measure photostress recovery time in chronic alcoholics males; (2) To measure photostress recovery time in apparently healthy males; (3) To compare photostress recovery time in apparently healthy males and chronic healthy males Material and methods: Photostress recovery time was recorded using Photostress Recovery Tester (GT – 991 Medicaid: Chandigarh). The subject was presented with a high beam of light focused on the eyes of subjects for short and fixed period of time. As soon as light stimulation was over, a word was displayed on screen for subject to read and automatically the clock started counting in seconds. When the subject recognized the word displayed he pressed the stop button on the remote control and read it out aloud, the clock stopped counting and word disappeared. Result: The p-value was statistically significant with a value of 0.003 showing a comparable difference of PSRT in group I and group II. Conclusion: Alcohol predisposes nervous tissue to injury via multiple mechanisms, including the development of oxidative stress. Retina is another among the vulnerable area for redox changes caused due alcohol intoxication, with lower threshold levels of ethanol tolerance.
