Abstract

Aim: To report OCT findings in type 2 MacTel and correlate with clinical stages and visual acuity (VA).

Methods: Cases of type 2 MacTel with macular OCT images were analysed retrospectively. Imaging features were tested for correlation with different clinicals stages and VA.

Results: 212 eyes of 108 patients were studied. Hyperreflective middle layer (87%) was frequently detected, followed by inner retinal cavities (49%), outward bending of inner retinal layers (35%), retinal pigment clumps [RPC] (35%) and irregular foveal contour (31%). Hyperreflective middle layers (p<0.001), inner (p=0.032) and outer retinal (p=0.002) cavities and ILM drape (p=0.031) were associated with poor VA in non-proliferative group and RPC (p=0.002), NSD (p=0.037) and foveal contour irregularity (p<0.001) were associated with poor VA in proliferative group. Conclusion: These OCT features are useful for diagnosis and staging in type 2 MacTel. RPC and SRNVM were linked with proliferative stage and poor VA.
