Assessment of the Success Rate Of Pneumatic Retinopexy In Patients With Rhegmatogenous Retinal Detachment and One Break Only

Abstract

Purpose : To assess the success rate of pneumatic retinopexy (PnR) in primary rhegmatogenous retinal detachment (RRD) in patients with a single break in detached retina and any number of breaks or lattice degeneration in attached retina.

Methods : Post-hoc analysis of three prospective clinical trials that included primary RRDs referred to St. Michael’s Hospital, Toronto, Canada between August 2012-July 2022. To be included in this study, patients had to meet PIVOT trial criteria (Hillier et al. 2018) but could have only one break in detached retina, with any number of breaks or lattice degeneration in the attached retina.

Results : A total of 231 consecutive patients were included. All patients had a minimum of 6 months of follow-up and 92.6 % had one year or more.29.7% of patients were female with a mean age of 60 (±11.3) and 54.4% were phakic. The primary anatomic reattachment rate was 87% (201/231). 44% (12/30) of patients who failed were found to have additional breaks that were visualized at the time of pars plana vitrectomy (PPV).

Conclusions : Pneumatic retinopexy provides durable long-term reattachment for patients that meet clinical trial criteria. The primary reattachment rate in patients meeting PIVOT trial criteria was 81% in the trial. In this large prospective cohort, primary reattachment rate increased to 87% when only patients with a single break in detached retina and any number of breaks or lattice degeneration in attached retina were included.
