Source: Laboratory of Dr. B. Jill Venton - University of Virginia Capillary electrophoresis (CE) is a separation technique that separates molecules in an electric field according to size and charge. CE is performed in a small glass tube called a capillary that is filled with an electrolyte solution. Analytes are separated due to differences in electrophoretic mobility, which varies with charge, solvent viscosity, and size. Traditional electrophoresis in gels is limited in the amount of voltage...

FAQs
Their layered arrangement places capillary networks within different levels of the retina, allowing neural tissue to receive oxygen and nutrients while metabolic waste is removed. This organization is important because the inner retina does not receive direct circulation from the choroid; its health therefore depends on the integrity and coordinated function of these retinal vascular layers.
Neurovascular coupling links neural activity with local blood-flow regulation. In the retina, this mechanism helps adjust microvascular support where neural tissue is active, rather than treating blood delivery as uniform throughout the tissue. This makes local flow regulation an important consideration when interpreting retinal vascular function.
The capillary walls are thin, which supports exchange between the circulation and surrounding retinal tissue. That exchange supplies oxygen and nutrients and assists removal of metabolic waste. Because the inner retina lacks direct circulation from the choroid, the condition of these small vessels and their walls is especially relevant to maintaining the local environment required by neural tissue.
Optical coherence tomography angiography, or OCTA, evaluates retinal microvascular architecture and can identify capillary loss, areas of nonperfusion, and abnormal remodeling. These findings allow clinicians and researchers to examine vascular changes in relation to retinal disease and use observed patterns as biomarkers of affected tissue.
Capillary loss, nonperfusion, and abnormal remodeling are not merely descriptive imaging findings; they are measurable signs of altered retinal microvascular architecture. Evaluating these features helps identify vascular involvement and provides biomarkers for diabetic retinopathy, retinal vascular occlusions, glaucoma, and other diseases that affect vision.
Several disorders can affect the retinal microvasculature, so examining the retinal capillary plexus provides a common vascular perspective across diabetic retinopathy, retinal vascular occlusions, and glaucoma. Assessment focuses on whether capillary networks remain present, perfused, and normally remodeled. Linking these observations to disease helps characterize changes associated with impaired vision.
