Peeling of Internal Limiting Membrane vs no ILM Peeling in Surgery for Rhegmatogenous Retinal Detachment by Francesca Guidolin, Sandro Soldati, Pietro Viola, Francesco Petti, Roberto Cian, Italy


ABSTRACT

Background:

The efficacy of peeling of internal limiting membrane (ILM) in preventing post surgery complications is controversial.

Aim:

To evaluate the incidence of macular complications following pars plana vitrectomy (PPV) for regmatogenous retinal detachment.

Methods:

Data from patients affected by regmatogenous retinal detachment undergoing PPV between October 2012 and July 2016 were retrospectively evaluated. Features of retinal detachment, visual acuity and the presence of post-operative complications (macular edema, macular pucker and macula-off recurrence of retinal detachment) were recorded. A comparison between the ILM peeling group and the non-peeling group was obtained by Chi-square test, Pearson\’s correlation coefficient and Fisher’s exact test; results were taken as significant if p<0.05.

Results:

We analyzed 105 eyes affected by regmatogenous retinal detachment: eighty-five eyes (80.9%) underwent PPV with ILM peeling, while twenty eyes (19,1%) were treated without ILM peeling. The procedure was independent from macular condition at onset (p=0.0952). Thirty-four eyes (32.4%) had a macula-on retinal detachment, while in seventy-one eyes (67.6%) macula was detached. The mean visual acuity was 0.25±0.32, and it significantly increased by 0.43±0.32 (p<0.0001), without significant difference between groups. The incidence of complications was not related to ILM peeling procedure (p=0.6303 for macular edema, p=1 for macular pucker, p=0.35 for macula-off recurrence of retinal detachment). The statistical analysis suggests a correlation of macular pucker with silicone oil tamponade (p=0.0252), but data should be confirmed increasing sample size.

Conclusion:

ILM peeling procedure seems not to prevent macular complications in regmatogenous retinal detachment surgery.
