To evaluate the recurrence rate of epiretinal membrane (ERM), visual outcomes and anatomical outcomes on spectral-domain optical coherence tomography (OCT) following vitreoretinal surgery for idiopathic ERM with internal limiting membrane (ILM) peel using Trypan Blue + Brilliant Blue staining.
Centro Médico Oftalmológico Bajaire, Bogotá D.C., Colombia.
A retrospective consecutive case series study of patients who had underwent surgery for idiopathic ERM by a single surgeon (B.B.), follow-up of >6 months, from October 3, 2008 to June 30, 2016, the incidence of recurrence of ERM, were evaluated, best corrected visual acuity (BCVA), and OCT were evaluated preoperatively and at least 6 months after the surgery.
We included 140 patients with idiopathic ERM diagnosis. The incidence of recurrence of ERM was 2.8% (4 patients), a decrease in central macular thickness of 23.5% (average of 63 microns), parafoveal 12.1% (average of 41 microns) was achieved, and an improvement in an average BCVA of 4 lines of vision (20/100 to 20/40).
This study demonstrates that new vitreoretinal techniques, especially chromovitrectomy, is effective both structurally and functionally in patients with idiopathic ERM, given that an effective peel was found at the sixth month of surgery or more, with improvement of the foveal anatomy and with very low incidence of recurrence of the ERM (2.8%). The results in visual acuity showed an average improvement of 4 lines of vision.
