Abstract

Purpose : To define morphologic features of epiretinal membrane (ERM) using en face images from swept-source optical coherence tomography (SS OCT).

Methods : 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.

Results : 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%).

Conclusions : En face SS OCT provides an useful tool to visualize the pathologic features in epiretinal membrane.
