External drainage of Subretinal Fluid during Rhegmatogenous
A Study was conducted to describe the safety and efficacy of rhegmatogenous retinal detachment (RRD) repair with external drainage of subretinal fluid using a 28-gauge External Drainage and Depression device.

Retrospective review of patients who underwent primary rhegmatogenous retinal detachment repair with scleral buckle, pars plana vitrectomy, or scleral buckle/pars plana vitrectomy using the drainage device was done.

--83 eyes of 83 patients were included. At presentation, 28% had proliferative vitreoretinopathy.

--Surgery included 65% scleral buckle/pars plana vitrectomy, 33% pars plana vitrectomy, and 2% scleral buckle.

--There were no cases of retinal incarceration and two subretinal hemorrhages at the drainage site, 2 cases of recurrent RD with proliferative vitreoretinopathy, and 6 new epiretinal membranes (3 were mild).

--There were no other complications. Mean follow-up was 274 days. Single operation success rate for those with more than 6-month follow-up was 97%.

Finally, external draining of subretinal fluid during rhegmatogenous retinal detachment repair was found to have a favorable safety profile and a high single-surgery success rate.
