Retinal Microvascular Clues to Alzheimer Disease: What Swept-Source OCT Angiography Reveals About Neurovascular Dysfunction

By MedXY 06/19/2026

SS-OCTA identified retinal and choriocapillaris microvascular changes associated with cognitive status in Alzheimer disease, including thinner GCC in dementia and a biphasic CCFD pattern, suggesting a promising noninvasive biomarker platform.

Progression in Preperimetric Glaucoma Eyes With and Without Microvasculature Dropout

By MedXY 06/02/2026

In preperimetric glaucoma, baseline microvasculature dropout on OCTA predicted faster capillary density loss and a higher risk of later visual field damage, suggesting it may help identify eyes needing closer follow-up.

Association of Deep Optic Nerve Head Structural Remodeling with Choroidal Microvasculature Dropout in Glaucoma with and without Myopia

By MedXY 04/21/2026

Study reveals significant links between optic nerve head structural changes and choroidal microvascular dropout in glaucomatous eyes, particularly in myopia. Deep structural parameters like neural canal geometry strongly correlate with microvascular damage severity.
