Effect of surgical modality on visual outcomes for young patients with primary rhegmatogenous retinal detachments: a retrospective cohort study

Abstract

Objective To examine outcomes of different surgical modalities for correcting primary rhegmatogenous retinal detachments in patients younger than 50 years of age.Methods and analysis A single-centre, retrospective, cohort study of 754 patients who underwent retinal surgery at the University of Virginia Hospital between 1 July 2012 and 1 July 2020 was conducted. Exclusion criteria were patients less than 18 or over 50 years of age, repeat detachments, second eyes of patients with bilateral detachments and follow-up less than 3 months. A multivariate regression model was used to compare overall outcomes in patients.Results 86 patients met inclusion criteria and of those, 38 (44%) underwent vitrectomy, 22 (26%) underwent scleral buckling, 13 (15%) underwent pneumatic retinopexy and 13 (15%) underwent combined scleral buckle and vitrectomy repair. Comparison of eye-level parameters among the procedure groups shows difference with respect to macular involvement (p<0.05) but not regarding clock hour involvement or giant tear status (p>0.05). Preoperative visual acuity was superior in the scleral buckle group compared with vitrectomy (p<0.001). Mean postoperative visual acuity improved with all procedures and all repair procedures had comparable rates of complication. The mean overall anatomical success rate was 73% (n=63) and comparable among all modalities.Conclusions Vitrectomy, scleral buckle, pneumatic retinopexy or combined procedures are viable repair options for rhegmatogenous retinal detachments in patients younger than 50 years of age. Selection of the repair modality should be guided on baseline clinical features of the patient and detachment.
