Purpose To present the reoperation rates of patients who underwent a primary noncomplex RD repair in a cohort of the American Academy of Ophthalmology IRIS Registry. Design Retrospective, nonrandomized comparative clinical study. Methods This was a retrospective, nonrandomized cohort study of patients who underwent a primary noncomplex RD repair with either a scleral buckle (SB) or vitrectomy with or without scleral buckle (PPV[plus or minus]SB) between 2013 and 2016. The primary outcome was the odds of reoperation within 12 months. Results Of 24,068 patients, 2,937 patients (12.2%) underwent an SB and 21,131 patients (87.8%) a PPV [plus or minus] SB. The overall reoperation rate was 12.2% for SB and 11.6% for PPV [plus or minus] SB. After multivariate adjustment for age and initial RD diagnosis, the PPV [plus or minus] SB group exhibited a lower odds of reoperation within 12 months compared with SB only (OR 0.84, 95% CI 0.75-0.96, P = .007). However, there was an age interaction. Patients [less than or equal to]50 years old with PPV [plus or minus] SB exhibited a higher odds of reoperation (OR 1.46, 95% CI 1.14-1.88, P = .003) compared to SB only. Patients >50 years with PPV [plus or minus] SB had a lower odds of reoperation (OR 0.73, 95% CI 0.63-0.84, P < .0001). Conclusion The odds of reoperation of PPV [plus or minus] SB compared with SB only varies depending on the patient's age. Further subset analyses are required to determine if there are clinically relevant differences with respect to RD configuration or other RD repair types (PPV only vs PPV with SB).
