Aim:
The objective of this study was to find out the effect of religious fasting on intra-ocular pressure.
Methods:
Intra-ocular pressure 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 intra-ocular pressure during fasting and the non-fasting period (P < 0.001). There was weight loss ranging from 0.4 to 1.5 kg.
Conclusion:
Fasting alters the diurnal intra-ocular pressure in the study population, ie young males 22-38 years.
