Abstract Details

Purpose:

To determine whether internal limiting membrane (ILM) peeling during pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD) reduces the incidence of epiretinal membrane (ERM) formation.

Setting:

Institute of Ophthalmology, University of Parma - Parma (Italy)

Methods:

In this retrospective study, preoperative, intraoperative and postoperative data from all eyes undergoing PPV for RRD between January 2007 to December 2013 was analyzed. All cases with at least one-year follow up were included. Data collection included vision, intraoperative complications, occurrence of ERM and spectral domain optical coherence tomography (SD-OCT) characteristics. The OCT scans were retrieved for all eyes and were graded by a single masked grader.

Results:

Out of 159 eyes recruited, ILM peeling was done in 78 eyes (49%). Overall occurrence of ERM was 20%. Seven eyes (9%) in ILM peeling group and 25 eyes in the non-ILM peeling group (31%) showed ERM (p=0.001). Postoperative vision was significantly better in eyes that had ILM peeling (0.48+0.4 logMAR vs. 0.77+0.6 logMAR, P=0.003). In multivariable models adjusting for type of tamponade, ILM peeling reduced the likelihood of ERM formation by 75% (P=0.01).

Conclusions:

Internal limiting membrane peeling during PPV for RRD significantly reduces ERM formation in the postoperative period and is associated with better visual and anatomical outcomes.
