Comparing the Effect of the Water Drinking Test on Intraocular Pressure

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.
