Purpose:
This study evaluates outcomes of comparable pseudophakic rhegmatogenous retinal detachment (RRD) treated with pars plana vitrectomy (PPV) or PPV with scleral buckle (PPV-SB).
Design:
Multicenter, retrospective, interventional cohort study.
Participants:
Data were gathered from patients from multiple retina practices in the United States with RRD in 2015.
Methods:
A large detailed database was generated. Pseudophakic patients with RRD managed with PPV or PPV-SB were analyzed for anatomic and visual outcomes. Eyes with proliferative vitreoretinopathy, giant retinal tears, previous invasive glaucoma surgery, and ≤90 days of follow-up were excluded from outcomes analysis. Single surgery anatomic success (SSAS) was defined as retinal attachment without ongoing tamponade and with no other RRD surgery within 90 days.
Main Outcome Measures:
Single surgery anatomic success and final Snellen visual acuity (VA).
Results:
A total of 1158 of 2620 eyes (44%) with primary RRD were pseudophakic. A total of 1018 eyes had greater than 90 days of follow-up. Eyes with proliferative vitreoretinopathy, previous glaucoma surgery, and giant retinal tears were excluded, leaving 893 pseudophakic eyes eligible for outcome analysis. A total of 461 (52%) were right eyes. A total of 606 patients (67%) were male, with a mean age of 65±11 years. Pars plana vitrectomy and PPV-SB as the first procedure were performed on 684 eyes (77%) and 209 eyes (23%), respectively. The mean follow-up was 388±161 days, and overall SSAS was achieved in 770 eyes (86%). Single surgery anatomic success was 84% (577/684) for PPV and 92% (193/209) for PPV-SB. The difference in SSAS between types of treatment was significant (P = 0.009). In eyes with macula-on RRD, SSAS was 88% in eyes treated with PPV and 100% in eyes treated with PPV-SB (P = 0.0088). In eyes with macula-off RRD, SSAS was 81% in eyes treated with PPV and 89% in eyes treated with PPV-SB (P = 0.029). Single surgery anatomic success was greater for PPV-SB than PPV for inferior (96% vs. 82%) and superior (90% vs. 82%) detachments. Mean final VA was similar for PPV (20/47) and PPV-SB (20/46; P = 0.805).
Conclusions:
In pseudophakic RRDs, SSAS was better in patients treated with PPV-SB compared with PPV alone, whereas visual outcomes were similar for both groups.
