Head tilt significantly altered Cirrus OCT RNFL measurements but not Spectralis OCT. This means head position can impact glaucoma monitoring with some devices, requiring careful patient positioning.

This study compared RNFL measurements between Cirrus and Spectralis OCTs. Both showed good repeatability and agreement, but Spectralis generally measured thicker, and pupillary dilation improved Cirrus's repeatability. This guides clinical interpretation across devices.

This study found endoscopic cyclophotocoagulation effectively lowered IOP and medication use in Asian glaucoma patients, but with a lower success rate and waning effect compared to Caucasian populations, suggesting cautious application.

This study found eyes with more pigment loss in PDS/PG had a flatter posterior corneal surface, suggesting anatomical differences may contribute to disease progression and reverse pupillary block.

This study compared glaucoma classification tools, finding GPS and MRA performed similarly, but disc size impacted all tools, suggesting GPS offers comparable utility without extra steps.

This study found asymptomatic primary angle-closure glaucoma often presents with severe visual field loss, while symptomatic cases present with milder defects, highlighting the silent, destructive nature of asymptomatic PACG.
