Purpose: To assess the relationship between the intraocular pressure (IOP) peaks detected during the water drinking test (WDT) and the modified diurnal tension curve (MDTC) in both normal and glaucomatous eyes.

Basic Procedures: An interventional prospective study that comprised eighty eyes from forty participants. All patients were above 40 years, with primary open-angle glaucoma (POAG) controlled surgically or medically or glaucoma-suspect patients. The control group had normal IOP and a normal examination.

Main Findings: The study included 80 eyes from 40 participants of which 20 (50%) were males and 20 (50%) were females. There was a statistically significant difference between the mean mDTC value and the associated WDT peaks among the whole study group (p=0.003), the normal group (p=0.041) and the glaucoma suspects group (p<0.0001) with no significant difference within the other groups.

Principal Conclusions: Intraocular pressure peaks detected during the water-drinking test can be used as a tool to estimate the observed peaks during the modified diurnal tension curve. However, a larger sample may be required to assess whether it is an equivalent alternative measure of IOP fluctuations.
