“…Other provocative tests, such as the proneposition dark adaptation test, were used in the past for this purpose and yielded conflicting results. [24][25][26][27][28] As mentioned previously, none of the eyes in our study developed an AACC during the WDT, and the IOP curves prior to, and following the LPI were very similar. Nevertheless, we did find a statistically significant change in IOP recovery following the LPI, when we measured the difference between the maximal and minimal IOPs during the WDT.…”

“…We speculated that a significant IOP elevation following the WDT in PACS before an LPI was made and could help determine which patients are at greater risk for PACG or AACC, in addition to their anatomical definition as PACS. Other provocative tests, such as the prone‐position dark adaptation test, were used in the past for this purpose and yielded conflicting results …”

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.

“…Desgroseilliers and colleagues 65 found that among patients who had undergone laser peripheral iridotomy, those with positive prone dark-room provocative testing had significantly more synechial angle closure of 180 degrees or more (35% vs 0%; P = 0.008) and more frequent double-hump sign (59% vs 11%; P = 0.005), reflecting an anteriorly positioned ciliary body. They therefore concluded that dark-room provocative testing may help identify patients at higher risk of intermittent increases in IOP.…”

Purpose The objective of this study was to provide the practicing clinical ophthalmologist with an update of pertinent glaucoma literature published from 2012 to 2013. Design Literature review. Methods The authors conducted a 1-year (July 1, 2012, to September 30, 2013) English-language glaucoma literature search on PubMed using the following terms: glaucoma, automated perimetry, optic nerve imaging, optical coherence tomography, glaucoma structure and function, intraocular pressure, central corneal thickness, glaucoma medical therapy, neuroprotection, glaucoma laser treatment, secondary glaucoma, glaucoma surgery, and miscellaneous topics in glaucoma. Results Of 2659 articles on glaucoma published during our time frame, this review selected original and review articles that reflect novel aspects and updates in the field of glaucoma, while excluding letters to the editor, unpublished works, and abstracts. Preference was given to human research. Conclusions This review focuses on literature that is applicable to ophthalmologists in practice and also highlights studies that may enhance the diagnosis and management of glaucoma.
