Optical coherence tomography angiography parameters after cataract surgery

Purpose To evaluate the changes in macular blood flow after cataract surgery through optical coherence tomography angiography (OCT-A). Methods In this prospective case series, 50 patients who underwent uncomplicated cataract surgery by the resident were included. OCT-A images and complete ocular exa...

Description
Summary:Purpose To evaluate the changes in macular blood flow after cataract surgery through optical coherence tomography angiography (OCT-A). Methods In this prospective case series, 50 patients who underwent uncomplicated cataract surgery by the resident were included. OCT-A images and complete ocular examinations were performed at baseline, 1 and 3 months postoperatively. The changes in OCT-A parameters including foveal avascular zone (FAZ) area, vessel density (VD) of superficial and deep plexus, and central macular thickness were assessed before and after surgery. Cataract grading, intraocular inflammation, and duration of surgery were analyzed. Results FAZ was significantly reduced from 0.36 ± 0.13 mm 2 at baseline to 0.32 ± 0.12 mm 2 at month 1 ( P
