Optical coherence tomography angiography (OCTA) showed high sensitivity and specificity for the diagnosis and treatment of diabetic macular edema (DME), according to the results of a study published in Photodiagnosis and Photodynamic Therapy. Investigators enrolled 86 patients with suspected DME. The study assessed OCTA’s sensitivity, specificity, and accuracy against the gold standard of fundus angiography and evaluated the impact of laser photocoagulation in patients with clinically significant macular edema (CSME), a severe form of DME, for tracking changes in several key indicators through OCTA. The comparative analysis with OCTA demonstrated OCTA’s sensitivity (97.94%) in diagnosing CSME, with a specificity of 63.64%. OCTA exhibited an accuracy rate of 87.23%, with a strong correlation (Kappa, 0.674) with fundus angiography. The findings underscore OCTA’s potential as a reliable diagnostic tool for assessing and monitoring diabetic macular edema, according to the investigators, and the study highlights OCTA’s diagnostic precision and potential role in evaluating treatment efficacy.
