Glaucoma Clinic Monitoring Over 6 Months Using Online Circular Contrast Perimetry in Comparison with Standard Automatic Perimetry: The Developing-World Setting.

Purpose: Online circular contrast perimetry provides visual field testing on any computer or tablet without additional hardware. This study compared outcomes of online circular contrast perimetry (OCCP) and standard automated perimetry (SAP) in a developing world setting.

Methods: The longitudinal and observation study was conducted on patients sampled during 2023 at Hanoi Medical University Hospital.

Online circular contrast perimetry via a web-application: optimising parameters and establishing a normative database.

Purpose: To establish a normative database and optimise parameters for personal-computer based perimetry via a web-application using circular contrast targets.

Methods: Online 24-degree 52-loci perimetry was delivered through a web-application using circular flickering contrast targets. Embedding contrast differentials within targets allows calculation of relative decibel (rdB) per 256-bit greyscale level differential.

The Computerized Glaucoma Visual Function Test: A Pilot Study Evaluating Computer-Screen Based Tests of Visual Function in Glaucoma.

Purpose: We aimed to develop and evaluate the Computerized Glaucoma Visual Function Test (CoGVFT), among a cohort of glaucoma patients, and identify potential new items to optimize the test.

Method: A cross-sectional study involving 84 patients with open-angle glaucoma of varying severity and 18 controls without glaucoma were recruited. Better and worse eye visual field parameters, visual acuity, contrast sensitivity, 6-Part Cognitive Impairment Test (6CIT) and Glaucoma Activity Limitation-9 (GAL-9) questionnaire responses were recorded.

Comparison of perimetric Glaucoma Staging Systems in Asians with primary glaucoma.

Background: To compare functional staging classifications in Vietnamese patients with primary open angle glaucoma (POAG) and chronic primary angle closure glaucoma (PACG).

Methods: A retrospective cross-section study was conducted at a national setting. Two hundred seven eyes of 207 patients were recruited.

Drug-induced Myopia and Bilateral Angle Closure Secondary to Zolmitriptan.

Purpose: To describe a unique case of drug-induced transient myopia with angle-closure glaucoma in a patient being treated with zolmitriptan for migraines.

Methods: A 42-year-old woman who had been using increasing amounts of zolmitriptan over the previous 12 months presented with an acute myopic shift and raised intraocular pressures (IOP) with anterior chamber shallowing. Clinical examination findings at presentation and at follow-up visits were reviewed.
