Reoperation Rates of Patients Undergoing Primary Noncomplex Retinal Detachment Surgery in a Cohort of the IRIS Registry.

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±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 ± SB. The overall reoperation rate was 12.2% for SB and 11.6% for PPV ± SB. After multivariate adjustment for age and initial RD diagnosis, the PPV ± 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 ≤50 years old with PPV ± 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 ± 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 ± 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).
