Abstract Details

Purpose:

To specify the benefits of internal limiting membrane (ILM) peeling as a surgical adjunct in primary repair of retinal detachments (RD) complicated by grade B proliferative vitreoretinopathy (PVR).

Setting:

A retrospective comparative study included consecutive patients who underwent vitrectomy for primary RD complicated by grade B PVR between May 2010 and December 2015 at Nancy University Hospital (France).

Methods:

All patients were treated with SF6 or C2F6 gaz tamponade. The ILM was routinely peeled after staining from 2012. The best-corrected visual acuity and spectral-domain optical coherence tomography (SD-OCT) were collected at 1 and 3 months postoperatively, looking for epiretinal membrane formation, macular oedema or photoreceptor damage.

Results:

Thirty seven eyes who underwent ILM peeling (group 1) and 38 eyes without ILM peeling (group 2) were included. At the end of follow-up, anatomic success after single surgery was higher in group 1 (89%) than in group 2 (66%, p=0.03). Mean final visual acuity was 0.41 ±0.40 logMAR in group 1 versus 0.43 ±0.22 logMAR in group 2 (p=0.82). After 3 months follow up, we found no epiretinal membrane (ERM) formation on OCT scans in group 1 whereas 5 ERM (20%) were detected in group 2 (p=0.012). The 2 groups did not differ in terms of cystoid macular oedema occurence, macular thickness or photoreceptor damage.

Conclusions:

ILM peeling at the macula during vitrectomy for the treatment of retinal detachment complicated by grade B PVR may prevent a second surgery for redetachment or macular pucker.
