April 1, 2019
Clinical Trial
The Pneumatic Retinopexy versus Vitrectomy for the Management of Primary Rhegmatogenous Retinal Detachment Outcomes Randomized Trial (PIVOT).
Hillier RJ, Felfeli T, Berger AR, Wong DT, Altomare F, Dai D, Giavedoni LR, Kertes PJ, Kohly RP, Muni RH.
Main finding: In patient fulfilling study criteriae, pneumatic retinopexy offers superior visual acuity, less vertical metamorphopsia, and reduced morbidity when compared with pars plana vitrectomy in primary rhegmatogenous retinal detachment.
- Purpose: To compare outcomes of pneumatic retinopexy versus pars plana vitrectomy for the management of primary rhegmatogenous retinal detachment.
- Study type: Randomized controlled Trial
- Condition: Rhegmatogenous retinal detachment.
Participants: Rhegmatogenous retinal detachment.
-a single retinal break or a group of breaks in detached retina within 1 clock hour above the 8- and 4-o’clock meridian with any number, location and size of retinal breaks or lattice degeneration in attached retina.
- n=176
Intervention:
Group 1: pneumatic retinopexy
Group 2: pars plana vitrectomy

6 months | 79.2 | 68.6 | ||
12 months | 79.9 | 68.6 | +4.9 (PnR superior) | |
