This study found chronic kidney disease is consistently associated with thinning of retinal nerve and ganglion cell layers across diverse populations, suggesting kidney health impacts ocular nerve integrity.

Chong Rachel S, Li Hengtong, Cheong Alex J Y, Fan Qiao, Koh Victor, Raghavan Lavanya et al.

This study found a strong, bidirectional genetic link between myopia and glaucoma, mainly mediated by intraocular pressure. IOP-lowering treatment may benefit myopic eyes with glaucoma.

Teo Zhen Ling, Soh Zhi Da, Tham Yih-Chung, Yu Marco, Chee Miao Li, Thakur Sahil et al.

This study found 3.50% of people developed primary angle-closure disease in 6 years. Older age, higher eye pressure, and shallower anterior chambers increased risk, guiding screening efforts.

An algorithm using pre-LPI ASOCT measurements (iris concavity, angle recess area) predicted LPI success in PACS eyes with 79% accuracy, outperforming ophthalmologists. This aids LPI decision-making for PACS prophylaxis.

Ahmed valve implantation in Asian eyes effectively lowered IOP and medication use for 3 years, with a 23.9% failure rate; hyphema was a key failure risk.

This review highlights advanced imaging's role in understanding the lamina cribrosa's biomechanics and translaminar pressure in glaucoma, improving diagnosis and management.

Tan Nicholas Y Q, Tham Yih-Chung, Koh Victor, Nguyen Duc Quang, Cheung Carol Y, Aung Tin et al.

This study quantified how visual field test reliability (false answers) impacts sensitivity in normal eyes. Key finding: False negatives worsen mean deviation and pattern standard deviation, while false positives improve mean deviation, helping clinicians interpret unreliable results.

This study found that in children with refractive errors, while some macular ganglion cell-inner plexiform layer (GC-IPL) parameters correlate with axial length, minimum GC-IPL and all retinal nerve fiber layer (RNFL) parameters do not, aiding pediatric glaucoma diagnosis.

Koh Victor, Chua Jacqueline, Shi Yuan, Thakku Sri Gowtham, Lee Ryan, Nongpiur Monisha E et al.

Studying Asian eyes, higher iris crypt grading was linked to lower acute angle closure risk. Assessing iris crypts could help predict acute angle closure.

Chang Lan, Pan Chen-Wei, Ohno-Matsui Kyoko, Lin Xiaoyu, Cheung Gemmy C M, Gazzard Gus et al.

This study found staphyloma and chorioretinal atrophy are common macular changes in highly myopic Singaporean adults, while peripapillary atrophy and disc tilt are common optic disc findings, highlighting age-dependent pathology.

This study compared HRT-2 and HRT-3 in Asian eyes, finding good correlation but significant differences in stereometric parameters, suggesting conversion equations are needed for clinical use.

Loon Seng Chee, Tong Louis, Gazzard Gus, Chan Yiong Huak, Sim Ee Ling, Aung Tin et al.

This study found HRT optic disc measurements are highly consistent with or without disc photos for contouring, suggesting photos may be omitted in large studies to save time/cost without significant data loss.

Koh Victor, Cheung Carol Yim-Lui, Zheng Yingfeng, Wong Tien Yin, Wong Wanling, Aung Tin

This study found that straighter retinal vessels were significantly associated with a thinner neuroretinal rim, potentially aiding early glaucoma detection.
