This study found four specific genetic markers (SNPs) are associated with high-tension glaucoma (HTG) in Chinese and Japanese populations, suggesting distinct genetic mechanisms for HTG versus normal-tension glaucoma.

This study found standard visual field progression metrics underestimate severe glaucoma worsening. A targeted metric excluding undetectable points better reflects true progression, improving monitoring in advanced disease.

Ex-PRESS blebs in exfoliation glaucoma show smaller fluid spaces and more fibrosis than in POAG, indicating worse surgical outcomes and poorer IOP control due to differing healing.

This study found a genetic marker (rs4236601) at the CAV1-CAV2 locus linked to normal-tension glaucoma in Chinese, but not Japanese, suggesting ethnic differences in disease risk.

This study found epiretinal membranes are associated with worse glaucoma severity (thinner RNFL, larger cupping, worse visual fields) in POAG, suggesting ERMs may be a risk factor for progression.

Anterior segment Scheimpflug imaging, particularly anterior chamber depth, accurately detects primary angle closure disease. This non-invasive, reproducible method is a powerful screening tool for PACD.

OCT segmentation errors in RNFL and GCC scans are common, affecting up to 20.7% of scans, and are linked to signal strength, disc size, and disease. Clinicians must review raw OCT images to ensure accuracy.

SLT for open-angle glaucoma on maximal medical therapy showed limited 1-year IOP control. Success varied by glaucoma type and baseline IOP, suggesting SLT may be less effective in these advanced cases.

SS-OCT revealed peripapillary tilting, often inferotemporal, in highly myopic eyes, especially older ones. This tilt correlates with thinner choroid, more peripapillary atrophy, and deeper staphyloma, impacting glaucoma assessment.

This study found subfoveal choroidal thickness varies significantly throughout the day in healthy individuals, being thickest at night and thinnest in the evening, potentially linked to systolic blood pressure.

Highly myopic NTG patients showed significantly thinner choroids, especially foveally, compared to controls. This suggests choroidal thinning is linked to myopic NTG and may aid diagnosis.
