Purpose: To describe the methods of performing the water drinking test (WDT) and its applications in glaucoma management. Methods: This review is based on pertinent publications retrieved by a selective search in PubMed, supplemented by further articles chosen by the authors. Results: Intraocular pressure (IOP) changes throughout the day. IOP peak has been identified as a risk factor in glaucoma onset and progression. WDT is a simple stress test used by many researchers to elicit IOP peaks in assessing response to glaucoma treatments. Conclusions: Studies have shown the reproducibility and promising results of WDT in various pharmacological and surgical treatments of glaucoma. It is an important tool in glaucoma management.

Background: To evaluate the satisfaction of surgeons and trainees with three-dimensional (3D) ophthalmic surgery during a demonstration compared to traditional surgery Methods: This validated questionnaire-based study was conducted over 1-month during which Ngenuity 3D surgery was demonstrated. All surgeons and trainees exposed were recruited to complete a questionnaire comprising visualization, physical, ease of use, teaching and learning, and overall satisfaction. Results: All 7 surgeons and 33 postgraduate students responded. Surgeons reported no significant difference except overall (P = 0.047, paired t-test). Postgraduate trainees reported significantly better experience with 3D for illumination (P = 0.008), manoeuvrability (P = 0.01), glare (P = 0.037), eye strain (P = 0.008), neck and upper back strain (P = 0.000), lower back pain (P = 0.019), communication (P = 0.002), comfortable environment (P = 0.001), sharing of knowledge (P = 0.000), and overall (P = 0.009). Conclusions: During early experience, surgeons and trainees reported better satisfaction with 3D overall. Trainees had better satisfaction with 3D in various subcomponents of visualization, physical, ease of use, and education.
