Abstract

Abstract: : Purpose: To assess the possible influence of Water Drinking Test (WDT) on central corneal thickness (CCT) due to a sudden change in osmolarity since an increase on CCT could lead to false IOP readings with Goldmann's applanation tonometry. Methods: 38 glaucomatous or glaucomatous suspect patients without ocular hypotensive medication were submitted to WDT. CCT was measured by ultrasound pachymetry before and during the WDT. One eye of each patient was randomly selected for statistical analysis. Paired t test was used to compare IOP and CCT values during WDT. Results: Mean basal IOP was 18.45±5.41 mmHg. During WDT, the higher IOP readings occurred at 30 minutes. At this time point, mean IOP was 21.82±7.85 mmHg. This difference was statistically significant (p<0.001). Mean basal CCT was 0.535±0.034 mm. At 30 minutes, during IOP peak, mean CCT was 0.535±0.033 mm, without statistically significant difference (p=0.113). Conclusions: Despite the IOP rise after water ingestion in WDT there was no change on CCT. Thus, CCT should have no effect on IOP readings during this test.
