Purpose: The present study aimed to review the effect of dehydration during Ramadan fasting on the health and ocular parameters leading to changes in eye function. Methods: Articles included in the study were taken from Pub Med, Ovid, Web of Science and Google Scholar up to 2014.Related articles were also obtained from scientific journals in fasting and eye. Results: Dehydration and nutrition changes in Ramadan cause an increase in tear osmolarity, ocular aberration, anterior chamber depth, IOL measurement, central corneal thickness, retinal and choroidal thickness. And also a decrease in IOP, tear secretion, and vitreous thickness. Conclusion: Besides many research in relation to effect of dehydration impact on ocular parameters during Ramadan fasting, although the findings reveal it is associated with significant changes on ocular parameters. It seems requisite to have comprehensive study in "fasting and ocular parameters” which will be helpful in making decision and giving plan to the patients.
