Background: Oral water ingestion increases the blood volume, and hence the blood pressure, which in turn increases the intraocular pressure (IOP).
Aim: To know the effect of water ingestion on the IOP and the relationship between the IOPs of both the eyes, before and after water ingestion.
Settings and design: This comparative study was conducted on 36 male medical students in the department of Physiology.
Material and Methods: This study was conducted on 36 male medical students. The IOP was recorded every 30 minutes for 2 hours before and after water ingestion, with the subjects in the supine position, by using a Schiotz tonometer.
Statistical analysis: It was done by paired t test using SPSS 15.0 version.
Results: It was found that water ingestion increases the IOPs of both the eyes. The IOP of the left eye was insigficantly more by 0.2mmHg than that of the right eye in the control trial, but this was not so in the study trial. The transient increase in IOP was quick in the left eye than in the right eye after water ingestion.
Conclusion: It can be concluded that there is a difference between the IOPs of both the eyes, before and after water ingestion, whose cause cannot be clearly explained and therefore, this needs a further in depth study of the anatomical and physiological processes that govern the maintenance of the IOPs in both the eyes individually. This would also explain to a variable extent, the aetiology of some cases of unilateral glaucoma.
