Baseline characteristics of rhegmatogenous retinal detachments meeting the PIVOT trial criteria in an eye referral center in Colombia: case series

Objective This study aims to characterize the baseline profile and clinical outcomes of pneumatic retinopexy (PR) in patients fulfilling the Pneumatic Retinopexy versus Vitrectomy for the Management of Primary Rhegmatogenous Retinal Detachment Outcomes Randomized Trial (PIVOT) eligibility criteria at a tertiary referral center in Colombia. Methods This retrospective consecutive case series included patients with primary rhegmatogenous retinal detachment (RRD) meeting PIVOT criteria between January 2021 and April 2024. The primary outcome was single-operation success (SOS) at 3 months, defined as complete retinal reattachment after one PR procedure, allowing for a supplementary gas injection within 21 days. Results 563 newly diagnosed primary RRD cases were reported, 143 (25.4%) were PIVOT-eligible and 105 underwent PR. The SOS rate was 85.7% (90/105). Baseline age, sex, lens status, and macular status were comparable between success and failure groups. Detachment extent > 2 quadrants correlated with an increased risk of failure ( p = 0.045); however, this association should be interpreted cautiously given the limited number of events. Conclusions Approximately one-quarter of primary RRD cases at our center met PIVOT criteria. In this cohort, PR yielded a high SOS rate and remains a valuable first-line surgical option in appropriately selected patients, particularly in settings with constrained resources.
