Abstract

Purpose : To describe the usefulness of swept source optical coherence tomography (SS-OCT) in the pre- and post-operative times for epiretinal membranes (ERMs) and choroidal thickness evaluation and their correlation.

Methods : This prospective study included 19 eyes of 19 patients with idiopathic ERMs. We performed central macular (CMT) and choroidal thickness (CT) measurements before pars plana vitrectomy with ERM removal and internal limiting membrane peeling, subsequently 1 month and then 3 months after surgery. We perfomed combination 3D+5 Line Cross and scans centered on the fovea. CMT and CT were measured automatically using DRI-OCT mapping software.

Results : The mean age of the 19 patients was 69 years (SD: 8.4 years). Their mean preoperative visual acuity was 0.63 LogMAR (SD: 0.32) and mean CMT was 336.6 μm (SD: 115.1). Visual acuity improved from 0.63 LogMAR (SD: 0.32) at baseline to 0.32 LogMAR (SD: 0.35) at 3-months follow-up (p=0.04). Three months after vitrectomy with ILM peeling choroidal thickness remained unchanged from 237 μm (SD: 122) to 235 μm (SD: 104) (p=0.1).

Conclusions : The presence of the ERM, from our first results, appears to not modify significantly the choroidal thickness even after the normalization of the retinal profile following the surgery. Even though Michalewska Z. et al. (Choroidal thickness measured with swept source optical coherence tomography before and after vitrectomy with internal limiting membrane peeling for idiopathic epiretinal membranes, Retina 35:487-491, 2015) reported a connection between the presence of idiopathic ERM and choroidal thickness, the evaluation of a greater number of patients can be useful to establish whether ERM can play an important role against the variation of choroidal thickness.
