Anatomical and Functional Outcomes of Pneumatic Retinopexy for Retinal Detachment: A 2-Year Case Series

The goal of this observational study is to evaluate the 2-year anatomical and functional outcomes of pneumatic retinopexy in phakic adult patients with superior rhegmatogenous retinal detachment meeting adapted PIVOT eligibility criteria. The main questions it aims to answer are to determine the primary anatomical success rate over 24 months-defined as sustained retinal reattachment without secondary vitrectomy or scleral buckling-and to evaluate long-term visual acuity outcomes and structural macular integrity measured by OCT. As a single-arm observational case series, participants undergo baseline ophthalmic evaluation (BCVA, OCT, and fundus photography), followed by a standardized outpatient procedure consisting of anterior chamber paracentesis (0.3 cc), inferotemporal intravitreal 100% C3F8 gas injection (0.7 cc), face-down positioning followed by the steam-roll maneuver, postoperative 577-nm yellow laser retinopexy with a 360° peripheral barrier upon reattachment, and protocolized follow-up evaluations on Day 1, at 3 weeks, 6 weeks, 3 months, and up to 24 months.
