Purpose:
|
To evaluate the effect of water drinking test (WDT) on intraocular pressure (IOP) and ocular biometric parameters before and after laser peripheral iridotomy (LPI) in patients with an occludable angle.
|
|
Methods:
|
This interventional case series comprised 27 patients who met the inclusion criteria and had 180 degrees of iridotrabecular apposition. All patients underwent a complete eye examination, and then ocular biometric (using Lenstar LS 900) and anterior chamber parameters (using Pentacam HR) were measured. All measurements were repeated 30 minutes after WDT. Two weeks after LPI, all measurements were repeated before and after WDT as well.
|
|
Results:
|
The mean standard deviation of the age of the participants was 57±9 years and 23 (85.2%) were male. IOP increased after WDT in both pre- and post-LPI conditions (17.0 vs. 19.3 mm Hg, P < 0.001; and 15.6 vs. 18.6 mm Hg, P<0.001; respectively). Central corneal thickness values slightly increased after the WDT in pre- and post-LPI conditions (535 vs. 538 µm, P = 0.001; and 532 vs. 536 µm, P = 0.003; respectively). WDT had no significant effect on other biometric or anterior chamber parameters, before or after LPI.
|
|
Conclusion:
|
WDT increased IOP both before and after LPI. The LPI had no significant effect on the amount of IOP change after WDT. WDT has no effect on other biometric or anterior chamber parameters.
