This study found that poorer central vision sensitivity in the temporal papillomacular bundle (HFA 10-2) in advanced glaucoma predicts future visual acuity decline, guiding closer monitoring for vision loss risk.

This 5-year study found that in advanced glaucoma, baseline vision, peripapillary atrophy, and systemic antihypertensive use predict further central visual decline, even with controlled IOP, guiding closer monitoring.

This study found that OCT-measured retinal nerve fiber layer and macular thicknesses decrease with age, and axial length also impacts these measurements, varying by OCT device and fundus area.

OCT's ability to detect early glaucoma in highly myopic eyes varies significantly based on whether the normative database includes highly myopic controls. This highlights the critical need for high-myopia-specific normative data for accurate diagnosis.

Studying eyes with chiasmal damage, researchers found nasal retinal nerve fibers predominantly enter the optic disc at 1 and 5 o'clock, aiding glaucoma diagnosis by identifying specific fiber loss patterns.

IcareONE tonometer, used by patients or doctors, showed excellent agreement with Goldmann tonometry, making it reliable for home IOP monitoring, though CCT and age can influence its readings.

This study found SD-OCT's average cpRNFL and GCC measurements similarly diagnose highly myopic glaucoma, with RTVue showing better nasal cpRNFL detection and 3D OCT better mRNFL than Cirrus.

Macular OCT grid-pattern cluster analysis showed superior sensitivity for detecting early and preperimetric glaucoma compared to average thickness, offering a more reliable diagnostic approach.

This study compared three OCTs for glaucoma diagnosis, finding similar overall performance but RTVue excelled in nasal RNFL and superior GCC, offering nuanced diagnostic strengths.

Comparing three OCTs for glaucoma, devices showed similar overall RNFL-visual field correlation, but varied retinotopic relationships. Importantly, about 60% of measured RNFL thickness is non-neuronal tissue.

SD-OCT effectively detects unique optic atrophy patterns in optic tract syndrome, showing distinct retinal nerve fiber and ganglion cell thinning. This aids diagnosis of this uncommon condition.

Nakamura Makoto, Ishikawa-Tabuchi Kumiko, Kanamori Akiyasu, Yamada Yuko, Negi Akira

This study found RTVue OCT outperformed Cirrus in detecting optic nerve band atrophy, especially in nasal sectors, suggesting RTVue may be more effective for diagnosing this specific condition.

This study found that three OCT devices measure RNFL thickness differently, with Cirrus showing smaller values. Despite correlations, they are not interchangeable due to significant measurement discrepancies.

Elevated IOP in rats reduced AQP9 in the optic nerve head and retina. This suggests AQP9 dysregulation, potentially impacting metabolite transfer, contributes to glaucomatous optic neuropathy.

This study imaged rat retinal ganglion cell axons after optic nerve injury, finding parallel degeneration of axons and cell bodies. This clarifies the timing of RGC loss, relevant for understanding glaucoma progression.

Tafluprost, a glaucoma drug, was found to directly protect retinal ganglion cells from apoptosis in lab and animal models. This suggests it may offer neuroprotection beyond pressure lowering in glaucoma.

This study compared visual field indices (MD, AGIS, CIGTS) with structural parameters in glaucoma. It found MD was comparable to other indices for assessing functional damage, particularly in advanced stages, suggesting MD remains useful clinically.

Glaucoma patients with hemifield defects showed optic disc damage even in "unaffected" areas, and structural-functional correlation wasn't linear, highlighting complex disease progression.

This study compared CSLO, SLP, and OCT for early glaucoma detection. SLP and OCT showed superior ability over CSLO to discriminate glaucoma suspects and early glaucoma, offering better diagnostic utility.
