Purpose: The optimal surgery to repair rhegmatogenous retinal detachment (RRD) is unknown. The purpose of this trial was to compare outcomes of pneumatic retinopexy (PnR) versus pars plana vitrectomy (PPV) for the management of primary RRD.Design: Prospective, randomized controlled trial. Participants: Patients with RRD demonstrating a single retinal break or a group of breaks in detached retina within 1 clock hour above the 8-and 4-o'clock meridians, with any number, location and size of retinal breaks or lattice degeneration in attached retina.Methods: Patients were randomized to undergo either PnR or PPV. Macula-on and macula-off patients were assigned to intervention group by stratified randomization and were treated within 24 and 72 hours, respectively.

The HealthBrain app was feasible in providing SSE to older adults with the appropriate smartphone device outside the laboratory setting. Challenges were identified with perceived capture of higher levels of SSE stages that used horizontal step patterns. This as well as technical issues with horizontal step patterns will be addressed by newer GPS technology in current smartphone devices. Most subjects stated they would continue to use the HealthBrain app and refer to their friends and family. We believe that our findings in a representative cohort support the HealthBrain app as a scalable intervention to promote cognitive health in older adults.

IMPORTANCE Pneumatic retinopexy (PnR) is associated with superior visual acuity and reduced vertical metamorphopsia compared with pars plana vitrectomy (PPV) for primary rhegmatogenous retinal detachment (RRD). It is important to determine postoperative photoreceptor integrity with both surgical techniques.OBJECTIVE To compare photoreceptor integrity on spectral domain-optical coherence tomography (SD-OCT) between PnR and PPV at 12 months postoperatively.
