Purpose: To assess long-term redetachment rates of the Pneumatic Retinopexy versus Vitrectomy for the Management of Primary Rhegmatogenous Retinal Detachment Outcomes Randomized Trial (PIVOT).

Design: Randomized controlled trial.

Subjects: PIVOT trial participants.

Methods: This study was performed at St. Michael's Hospital, Unity Health Toronto, Toronto, Canada. PIVOT trial participants who had undergone either pneumatic retinopexy (PnR) or pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD) repair with a minimum follow-up of 2 years were assessed for long-term redetachment by chart review or telephone interview. The latter was the only accepted method for those with <2 years of follow-up. Patients were only eligible if no reintervention to reattach the retina was performed within the first year of the initial procedure.

Main outcome measures: Long-term redetachment rates for PnR vs. PPV after RRD repair.

Results: Sixty-one participants who underwent PPV and 62 who underwent PnR were analyzed. The long-term redetachment rates were 0% and 1.61% (1/62) in the PPV and PnR groups, respectively (P = 0.32). The mean follow-up duration in years was 5.43 ± 3.60 vs. 5.51 ± 3.03 in the PPV and PnR groups, respectively.

Conclusions: There was no statistically significant difference in long-term redetachment rates for PnR vs. PPV. Both procedures are durable treatment options for RRD over an extended period, rarely requiring additional intervention for redetachment.
