To define morphologic features of epiretinal membrane (ERM) using en face images from swept-source optical coherence tomography (SS OCT).
Consequtive patients with idiopathic ERM were analyzed for en face imaging analysis within a 6-month period. All patients had undergone 3D volume scan of swept source OCT (Triton OCT, Topcon, Japan). The patients were devided into 3 groups, retinal thickening without retinal hole (Group 1); retinal thickening with macular pseudohole (Group 2); retinal thickening with lamellar macular hole (Group 3). Secondary ERM were excluded from analysis. En face imaging was analyzed on and under the level of ILM.
Mean patient age was 63.6±10.8 years (n=77). Mean central retinal thickness (CRT) in group 1, 2, and 3 was 422.3 ± 73.3um (n=32), 398.6 ± 45.5um (n=16) and 439 ± 67.2um (n=19).En face imaging under ILM level well visualized central tractional membrane (CTM), and imaging on the ILM level showed well radiating folds (RF) over the posterior pole.Group 1 had CTM over the fovea (100%), however Group 3 had CTM outside the fovea (80%).
En face SS OCT provides an useful tool to visualize the pathologic features in epiretinal membrane.
