To evaluate the effect of internal limiting membrane (ILM) peel in the functional and anatomic outcome of epiretinal membrane (ERM) surgery.
Multicenter, Prospective, Randomised, Controlled trial
One hundred two consecutive patients underwent pars plana vitrectomy and epiretinal membrane removal, with (Group P) or without (Group NP) ILM peel. Primary outcome measures were change in near and distance visual acuity and in central retinal thickness. Secondary outcome measures included improvement of metamorphopsia, recurrence of epiretinal membrane, and macular structural changes seen on OCT and on Autofluorescence images.
Fifty two and fifty patients were allocated in group P and NP respectively. Baseline visual acuity was 0.52 ± 0.24 and 12 months after surgery improved by 0.24 ±0.06 in Group P and by 0.25 ± 0.06 in Group NP (p=0.83). Central retinal thickness decreased by 123μ and 134μ in Group P and NP respectively (p=74). No ERM recurrences observed within the follow up period. There was no significant difference between the two groups regarding the improvement of metamorphopsia, restoration of normal foveal contour, changes in the IS/OS and resolution of preoperative foveal detachment.
ILM peel during ERM surgery does not appear to alter favorably the final functional and anatomic outcome.
