Effect of Type of Head Positioning on Retinal Displacement in Vitrectomy for Retinal Detachment

NCT04035343 · Status: UNKNOWN · Phase: NA · Type: INTERVENTIONAL · Enrollment: 324

No results posted yet for this study

Summary

Patients may experience metamorphopsia, or image distortion, after having vitrectomy to repair their rhegmatogenous retinal detachments especially those with a detached macula. Retinal displacement, as measured on autofluorescence photography, likely contributes to this distortion. It is thought that the retina slips inferiorly due to the residual subretinal fluid shifting as the patient transitions from the supine position intraoperatively to the sitting up position in the immediate postoperative period. By having the patient immediate position facedown or according to the retinal break, the risk of slippage is theoretically decreased.
