Retinal Displacement Rates in Pneumatic Retinopexy Versus Pars Plana Vitrectomy For Primary Retinal Detachment

NCT04158622 · Status: UNKNOWN · Phase: NA · Type: INTERVENTIONAL · Enrollment: 100

No results posted yet for this study

Summary

Patients may experience metamorphopsia, or image distortion, after having vitrectomy to repair their rhegmatogenous retinal detachments (RRDs) especially those with a detached macula. Retinal displacement, as measured on autofluorescence photography, likely contributes to this distortion. There is no study in the scientific literature comparing the rate of retinal displacement and its association with visual function, including metamorphopsia, in patients undergoing different procedures for RRD repair. Based on the recently published PIVOT trial, patients who underwent Pneumatic Retinopexy (PnR) had less vertical distortion at 12 months than patients who had Pars Plana Vitrectomy (PPV). It is hypothesized that PnR will cause less retinal displacement than PPV for patients with macula-off primary retinal detachment.
