ARREST, a new visual field test, increased spatial sampling in glaucoma patients without extending test duration, offering better defect description for clinical use.

Cataract surgery significantly reduces intraocular pressure (IOP) in early glaucoma patients, especially those with higher preoperative IOP, confirming its real-world benefit.

This Victorian audit found trabeculectomy alone effectively lowers eye pressure with good safety, comparable to international standards, but combined cataract surgery resulted in higher post-operative pressures.

Australian glaucoma laser/surgical trends (1994-2014) show a significant increase in laser trabeculoplasty and drainage devices, while primary filtering surgeries declined, impacting treatment strategies.

This paper proposes using the sufficient component cause model to understand individual PACD causation, suggesting personalized treatment by targeting specific causal components, like pupillary block, for each patient.

This study developed PACD management algorithms, finding laser iridotomy is often first-line, but subsequent steps depend on angle status, IOP, PAS, and cataract for further targeted interventions.

Evidence is insufficient to recommend lens extraction as a routine POAG treatment. It offers only modest, likely marginal IOP reduction, mainly in mild cases or with pseudoexfoliation.

Bayes' theorem helps ophthalmologists interpret diagnostic tests and manage patients by calculating probabilities, showing low prevalence testing has poor predictive value, and estimating risks.

This review found limited, weak evidence for clear lens extraction in angle closure glaucoma. No randomized trials support its use, despite biological plausibility, highlighting a need for more research.

Glaucoma impairs contrast discrimination and reduces the visual system's ability to adapt to varying contrasts, particularly for low-contrast stimuli, suggesting new insights into real-world vision.

This study found both normal aging and glaucoma reduce low-spatial-frequency contrast sensitivity in magnocellular and parvocellular pathways, with glaucoma causing further, non-selective impairment.

Experts recommend surgery (trabeculectomy) for glaucoma progression despite "normal" intraocular pressure on full medical treatment, highlighting that IOP alone isn't the sole treatment target.

Australian glaucoma treatment shifted 1994-2003 from surgery/laser to prostaglandin eye drops, increasing prescriptions and costs. This highlights a trend toward medical management, but long-term outcome data is needed.

This case series shows periorbital topical corticosteroids can cause sight-threatening glaucoma, even if considered innocuous. Use cautiously, especially with glaucoma history, as IOP may not normalize after stopping.
