“…In Asians, other biometric parameters like shorter axial length were reported to be associated with a positive WDT + DRPT [32]. We only measured Caucasian subjects, which might explain the different finding in our study in which axial length shows no association with a positive WDT + DRPT.…”

“…[4][5][6] Some studies have suggested the use of provocative tests, like the dark room test or the prone position test, to detect patients prone to PACG. 7,8 These tests aim to evoke an abnormal increase in IOP within the eye. Abnormal or exaggerated IOP responses to these stress tests in PACS can suggests an increased likelihood of these asymptomatic eyes developing PAC/PACG because of shallow anterior chambers and narrow angles; however, negative test results do not necessarily preclude later development of PACG.…”

Background: This study aimed to investigate whether performing a laser peripheral iridotomy in primary angle-closure suspects had an effect on the intraocular pressure response during the water-drinking test.Design: Prospective study in a hospital setting.Participants: Primary angle-closure suspects scheduled for a laser peripheral iridotomy.Methods: Primary angle-closure suspects were evaluated before the laser peripheral iridotomy and 2 weeks after. On each visit, subjects underwent the waterdrinking test. Intraocular pressure was measured every 15 min within a 1-h period.Main Outcome Measures: Intraocular pressure fluctuations during the water drinking test.Results: Twenty patients were enrolled. The mean age was 58.1 years (±10.2 SD), predominantly female (n = 14, 70%). Average intraocular pressure range (maximum-minimum) during the waterdrinking test increased significantly from 2.6 ± 1.1 mmHg before the laser peripheral iridotomy to 3.5 ± 1.5 mmHg after (P = 0.04). The mean difference between peak and last intraocular pressure measurements increased after the laser peripheral iridotomy was performed, from 2.5 mmHg (±1.27 SD) to 3.3 mmHg (±1.66 SD), (P = 0.057). There was no change in mean peak intraocular pressure (maximum-baseline) before and after the laser peripheral iridotomy (P = 0.87).Conclusions: Primary angle-closure suspects who underwent the water-drinking test had a slightly more pronounced recovery of intraocular pressure after the laser peripheral iridotomy was performed, which may be attributed to increase in the area of exposed trabecular meshwork following treatment. Differences in intraocular pressure curves before and after laser peripheral iridotomy were minimal, and therefore, the water-drinking test had limited value as a provocative test in this patient population.
