Kellogg Eye Center between January 1, 2011 and July 1, 2020. Clinical characteristics and preoperative, perioperative, and postoperative data were collected.Results: Forty-eight eyes of 47 patients with GRT-associated RRDs met inclusion criteria, including those that were children (under 12 years, N=4, 8.3%), associated with a history of trauma (N=20, 41.7%) or with grade C proliferative vitreoretinopathy (PVR-C) (N=7, 14.6%) at baseline. Median age was 46 years (interquartile range (IQR): 29 years, range: 4 to 72 years), median follow-up was 28 months (IQR: 43 months, range: 3– 124 months), and 83.3% (N=40) of subjects were male. Primary surgical repair for GRT-associated RRDs included pars plana vitrectomy (PPV) (N=40, 83.3%), scleral buckle (SB) (N=1, 2.1%), or combined PPV/SB (N=7, 14.6%). Surgical approach commonly involved the use of perfluorocarbon liquid (N=43, 90%) and gas tamponade (N=39, 81%). Single surgery anatomic success (SSAS) was 75% (95% CI: 60%, 85%) at 3 months and 65% (95 CI: 47%, 78%) at 2 years. Final anatomic success was achieved in all 48 eyes (100%). Median visual acuity improved from 20/250 preoperatively to 20/60 at final follow-up, ...
