Abstract Details



Purpose:

To evaluate the incidence rates of Epiretinal membrane (ERM) formation after uncomplicated primary 23-G and 25-G retinal detachment (RD) repair and to identify its relationship with the macula on/off status at diagnosis among other risk factors.

Setting:

Hospital Ramon y Cajal. Madrid, Spain.

Methods:

This was a retrospective 2 year cohort (2014-2015) of 39 patients that underwent one RD repair with 23-G or 25-G pars plana vitrectomy (PPV) and gas tamponde (either SF6 or C3F8). Epiretinal membrane were confirmed by spectral domain optical coherence tomography (SD-OCT). The macular on/off status at the diagnosis was confirmed by funduscopic examination and SD-OCT. Both variables were studied using Square Chi Test and Log-Rank survival test. Other variables as phacoemulsification and intraocular lens (IOL) implantation, cryotherapy and the use of scleral buckling were assessed as well. Exclusion criteria included diabetic mellitus, re-detachment, use of silicone oil as tamponade and internal limiting membrane (ILM) peeling during RD repair.

Results:

A total of 39 eyes with a mean follow-up of 520 days had incidence rates of 55.9% SD-OCT observed ERM with ILM peeling afterwards in 8.8% cases. Macula ON status was observed more unfrequently (35.3%). The incidence of ERM after RD surgery of the macula ON cases (75%) was greater (p=0.097) compared to that after macula OFF (45.5%).

Conclusions:

The increase of ERM after macula ON cases could be related to the need to induce a posterior vitreous detachment (PVD) during the surgery in most of the cases. The increase of ERM in our series would be associated with the exclusion criteria and also with the use of SD-OCT with higher sensibility while testing the presence of ERM.
