Abstract
Purpose :
To report incidence of postoperative epiretinal membrane (ERM) formation after primary pars plana vitrectomy (PPV) for giant retinal tear associated retinal detachment (GRT-RD) repair as well as clinical characteristics and visual outcomes at a level one trauma and tertiary referral academic center.
Methods :
Patients with primary RD repair for GRT-RD at West Virginia University from September 2010 to July 2021 were identified using the ICD-10 codes (H33.031, H33. 032, H33.033 and H33.039). The study included 17 eyes of 16 patients who underwent PPV for GRT-RD. Imaging studies including optical coherence tomography (OCT) were manually reviewed pre- and post-operatively for ERM formation after PPV for GRT-RD repair in patients who underwent PPV or combined PPV and scleral buckle (SB). Univariate analysis was done to analyze clinical factors for ERM formation.
Results :
Postoperative ERM was observed in 70.6% (13 of 17 eyes) of the patients. Anatomic success was achieved in all patients. The mean (range) preoperative and final best corrected visual acuity (BCVA) in logMAR units by macula status was 0.19 (0-0.5) and 0.28 (0-0.5) for macula-on and 1.7 (0.5-2.3) and 0.7 (0.2-1.9) for macular-off GRT-RDs. Clinical variables including use of medium-term PFCL, cryopexy, endodiathermy, number of tears or total clock hours of tears did not correlate with increased risk of ERM formation.
Conclusions :
Incidence of ERM formation after PPV for GRT-RD repair is high. Primary ILM peel at the time of primary repair can be more strongly considered when compared to a routine rhegmatogenous RD repair.
