AIM: The objective of this study was to discover the effect of religious fasting on intraocular pressure (IOP). METHODS: IOP by applanation tonometer was measured four times a day in 38 healthy young adult male patients. The mean age of patients was 29 years. Body weight was measured to assess the extent of dehydration caused by fasting. RESULTS: There was a statistically significant difference between the IOP during fasting and the non-fasting period (p < 0.001). There was weight loss ranging from 0.4-1.5 kg. CONCLUSION: Fasting alters the diurnal IOP in the study population, i.e., young males aged 22-38 years.
