Description
Summary:Summary OCT angiography (OCT‐A) as a new non‐invasive imaging technology that enables the monitoring of the macular circulation. OCT‐A has a better rate of detection either of the macular capillaries plexus or the distribution of the macular cystoid spaces, than using fluoserseine angiography (FA), allowing the evaluation, of either superficial or deep perifoveal capillary layers. During the evolution of the ischemic micro‐angiopathies, the appearance of the capillaries ischemic areas, the micro‐aneurysms, the capillaries segments dilations as well as the distributions and the evolution of the capillaries collaterals, can be monitored. The evaluation of the deep capillary plexus, appears to be more severely affected than the superficial capillary plexus, resulting to deep non perfused capillaries areas. The perifoveal capillary arcade disruption, observed on OCT‐A in eyes with retinal vein occlusions, was correlated with the presence of retinal peripheral ischemia. OCT‐A progressively became a useful imaging modality in the evaluation and management of macular hemodynamic changes observed during the evolution of the retinal ischemic micro‐angiopathies allowing to evaluate the treatment effects on the capillary circulation.
