Correlation between aqueous flare and macular microvascular status in diabetes mellitus

The authors report a cross-sectional study which was conducted to investigate the correlation between aqueous flare and macular microvascular status, assessed by optic coherence tomography angiography (OCTA) in diabetes mellitus. Fifty-two diabetic patients with non-proliferative retinopathy, 44 diabetic patients without...

Nerve head in healthy humans using OCT-angiography

Optical coherence tomography angiography (OCT-A) is a recent, dyeless, and noninvasive imaging technique for evaluating depth-resolved vascular status by capturing the dynamic motion of the erythrocytes. It provides the flow map of major vessels and capillary plexuses separately in different...

Duker et al. present the second edition of their Handbook of Retinal OCT. It’s an upgrade from their last edition in many respects – there’s an enhanced digital version, the pages have a nice glossy sheen which makes it feel...

Association between neurodegeneration and macular perfusion in the progression of diabetic retinopathy

In this prospective three-year longitudinal study, the authors aimed to explore the relation between retinal neurodegenerative changes and vessel closure (VC) in individuals with non-proliferative diabetic retinopathy (NPDR). The participants included 74 individuals with type 2 diabetes, NPDR, and Early...
