Comparing the Effect of the Water Drinking Test on Intraocular Pressure

Summary

A test that was common in the 1960's and was used to detect primary open angle glaucoma was the water drinking test (patients drank 1 quart of water to stress the fluid drainage mechanism of the eyes. Intraocular pressure was then measured over the next hour). Recently this test has been demonstrated as a predictor of peak eye pressure during the day. The purpose of this study is to compare the results of the water drinking test between eyes that have undergone trabeculectomy and eyes that have undergone tube shunt surgery.

PROCEDURE

Water Drinking Test

The Water Drinking test has been identified as a reliable and safe tool to predict maximum intraocular pressure values during a diurnal tension curve and to assess the efficacy of surgical interventions. Participants are asked to drink 10 ml/kg water (or approximately 0.33 ounces of water for every 2.2 pounds of weight or about 2.5 cups for a 150 lb. individual) over 15 minutes. Intraocular pressure is assessed every 15 minutes for one hour.
