To elucidate the en face optical coherence tomography (OCT) patterns of macular edema in eyes with angiographically documented uveitic macular edema (UME) and compare visual acuity (VA), OCT and OCT-angiography (OCT-A) parameters among the morphological subgroups. Thirty-nine eyes of 29 patients with angiographically proven UME were enrolled into the study. All patients underwent comprehensive ophthalmological examination including structural OCT and OCT-A in addition to fluorescein angiography. Eyes with UME were divided into three subgroups (petaloid, sunflower and spoke–wheel pattern) with the help of en face OCT imaging. Posterior uveitis was the most common type of uveitis (17 patients; 58.7%), followed by panuveitis (11 patients; 37.9%) and then intermediate uveitis (1 patient; 3.4%). Underlying causes of uveitis were Behçet’s disease (13 patients; 44.8%), idiopathic (11 patients; 37.9%), rheumatoid arthritis (2 patients; 6.9%), sarcoidosis (1 patient; 3.4%), inflammatory polyarthritis (1 patient; 3.4%) and psoriatic arthritis (1 patient; 3.4%). The most common en face OCT pattern was petaloid type (25 of 39 eyes; 64.1%). Eleven eyes (28.2%) had sunflower pattern and three (7.7%) spoke–wheel pattern. There were no statistically significant difference among the subgroups regarding the age, VA, central macular thickness and vessel density. This study reveals three morphological en face OCT patterns in eyes with UME and en face OCT may find a niche in the UME classification with the accumulation of experience among the uveitis experts.
