Adaptive optics imaging revealed narrower retinal nerve fiber bundles in glaucoma, even in early stages, correlating with visual field loss. This suggests AO SLO could detect early glaucoma damage.

This study found that in high myopia, increased peripapillary atrophy and scleral protrusion/bending are linked to retinal nerve fiber damage and vision loss, suggesting direct mechanical impact on the optic nerve.

This study found structural (OCT) and functional (FDT) tests poorly correlate but are complementary for detecting preperimetric glaucoma, suggesting their combination improves diagnosis.

Studying wide-area macular ganglion cell complex thickness, researchers found an 8mm diameter scan significantly improves glaucoma detection compared to a standard 6mm scan, enhancing early diagnosis.

AOSLO better visualizes lamina cribrosa pores; glaucomatous eyes show larger pore areas, correlating with axial length and IOP, suggesting its utility for glaucoma assessment.

Speckle noise-reduced SD-OCT clearly showed macular GCL thinning in preperimetric glaucoma, especially inferiorly. This method offers high sensitivity for early glaucoma detection, improving diagnosis before vision loss.

Enhanced SD-OCT, with speckle noise reduction, improved detection of localized retinal nerve fiber layer defects in glaucoma compared to other OCTs, offering better diagnostic sensitivity and specificity.

This study found that iris convexity in primary angle closure is greater with older age and shallower anterior chambers, highlighting structural factors contributing to angle closure.

Cataract surgery in angle closure eyes significantly widened the angle and moved ciliary processes backward, improving outflow. This shows cataract removal offers more than just lens volume reduction.

Nonaka Atsushi, Kondo Takehisa, Kikuchi Masashi, Yamashiro Kenji, Fujihara Masashi, Iwawaki Takuji et al.

Cataract surgery effectively resolved residual angle closure and lowered IOP after laser iridotomy, especially in eyes with prior high IOP or glaucoma, offering a key treatment for persistent angle closure.
