Tsai ASH, Gan ATL, Ting DSW, et al. - In this study, the association between macular microvasculature parameters and functional changes was explored in persons with diabetic retinopathy (DR). Researchers conducted a cross-sectional study including a total of 76 eyes with varying levels of DR. They assessed retinal sensitivity by applying microperimetry. They compared optical coherence tomography angiography parameters and retinal sensitivity. With increasing severity of DR, alterations in retinal microvasculature can be observed with optical coherence tomography angiography (OCTA). These variations are associated with decreased retinal sensitivity. Optical coherence tomography angiography was found to be beneficial to diagnose and evaluate the microvasculature properties of eyes with diabetic macular ischemia.
