    DME Microaneurysms Detected More on FA than OCT-A

    In diabetic macular edema (DME) patients, optical coherence tomography angiography (OCT-A) may detect fewer microaneurysms than fundus fluorescein angiography (FA), likely due to leakage and retinal thickening, new research reports. Investigators examined OCT-A and FA images of 31 eyes of 24 participants and graded them for microaneurysms. They found just 58% of microaneurysms detected on FA were also visible on OCT-A. Additionally, microaneurysms with focal leakage in a thickened retinal area were detected more frequently on OCT-A than non-leaking microaneurysms in non-thickened retinal areas. Most microaneurysms on OCT-A were seen in the intermediate (23%) and deep capillary plexus (22%). Of ...
