This study found SPECTRALIS GMPE and SGM modules, despite high correlation, yield significantly different RNFL thickness measurements. Clinicians must consider these differences when interpreting or transitioning between modules for glaucoma management.

In the glaucoma group, cumulative exposure to relative humidity of 61-69% and 78-89% over lag 0-6 days was significantly associated with reduced intraocular pressure (IOP).

MechanismCohortTime-series analysisn=25,173 IOP measurements over 1,182 days in the glaucoma group

In the glaucoma group, cumulative exposure to relative humidity of 79-88.5% over lag 0-13 days was significantly associated with reduced intraocular pressure (IOP).

In the glaucoma group, cumulative exposure to very high relative humidity (97-98%) over lag 0-6 days was significantly associated with increased intraocular pressure (IOP).

An association was reported between asymmetrical normal tension glaucoma (NTG) with obstructive sleep apnoea (OSA; apnoea-hypopnoea-index ≥5) in habitual side-sleepers.

In worse eyes of NTG-OSA patients, mean blur rate for tissue (MT) was less in the lower lateral decubitus (LD) position (9.00 ± 2.07 au) compared to the upper LD position (9.27 ± 1.97 au; P = 0.037) and supine position (9.61 ± 1.95 au; P = 0.011), suggesting reduced optic nerve head blood flow velocity in the lower LD position.

MechanismCross-sectionalCross-sectional studyn=40 NTG-OSA patients

Among NTG-OSA participants who slept with the worse eye lower, mean blur rates for vascular (MV), tissue (MT), and entire area (MA) were less in the worse eyes in both lower and upper lateral decubitus (LD) positions versus the fellow eye (all P < 0.05), but not in the supine position.

MechanismCross-sectionalCross-sectional studyn=40 NTG-OSA patients

Among NTG-OSA participants who slept with the worse eye upper, mean blur rates for vascular (MV) and tissue (MT) were less in the worse eyes only in the lower lateral decubitus (LD) position (both P < 0.05), with no differences in other positions.

Anterior scleral thickness at 0-3mm from the scleral spur (AST0) was significantly lower in primary open-angle glaucoma (POAG) and ocular hypertension (OHT) groups compared with controls in both nasal and temporal quadrants (all p < 0.001).

Schlemm's canal area (SCA) and scleral spur length (SSL) were significantly lower in primary open-angle glaucoma (POAG) and ocular hypertension (OHT) groups compared with controls in both nasal and temporal quadrants (all p < 0.001).

For anterior scleral thickness at 3mm from the scleral spur (AST3), temporal values were lower in primary open-angle glaucoma (POAG) and ocular hypertension (OHT) groups compared with controls (p < 0.001), while nasal AST3 showed no significant group difference.

In 2019, glaucoma comprised 11.7% of the total vision impairment burden among individuals with diabetes in Taiwan.

Higher serum Klotho levels were positively associated with glaucoma risk (odds ratio [OR] = 1.05 per 100 pg/mL increase; 95% confidence interval [CI], 1.01-1.09; P = 0.006) in 2952 participants aged 40 years and older from the 2007-2008 National Health and Nutrition Examination Survey.
