Diabetic retinopathy (DR) is a common complication of diabetes mellitus that disrupts the
retinal microvasculature and is a leading cause of vision loss globally. Recently, optical …

Biomarkers are conventionally defined as “biological molecules that represent health and
disease states.” They typically are measured in readily available body fluids (blood or urine) …

Purpose: We compared the area of the foveal avascular zone (FAZ) and macular capillary
network density at different retinal layers using swept-source optical coherence tomography …

Diabetic macular ischaemia (DMI) is traditionally defined and graded based on the
angiographic evidence of an enlarged and irregular foveal avascular zone. However, these …

Purpose: To quantify microvasculature changes in the superficial (SCP), middle (MCP), and
deep capillary plexuses (DCP) in diabetic retinopathy (DR). Methods: Retrospective cross …

The microcirculation plays a key role in delivering oxygen to and removing metabolic wastes
from energy-intensive retinal neurons. Microvascular changes are a hallmark feature of …

Aim To evaluate the correlation between inner retinal layer thinning and the foveal
microvasculature in type 2 diabetes using optical coherence tomography angiography …

Abstract Background Patients with Alzheimer's disease (AD) demonstrate the narrowing of
retinal veins and decreased retinal venous blood flow compared with control subjects. We …

The retinal blood vessels provide the opportunity to study early structural and functional
changes in the microvasculature prior to clinically significant microvascular and …

We investigated morphological changes of retinal arteries to determine their association with
the blood flow and systemic variables in type 2 diabetes patients. The patients included 47 …
