Abstract
Purpose: :
To evaluate safety and efficacy of fluorinated silicone oil as a endotamponade in proliferative vitreo–retinopathy with complicated retinal detachment
Methods: :
This is prospective, longitudinal, observational study of a case series. All patients should have at least 2 months of follow up. Patients with proliferative vitreo–retinopathy C2 stage or worse (according to updated classification of Retina Society). and complicated retinal detachment specifically with inferior retinal tear, with or without previous surgery. Patients were evaluated preoperatively and postoperatively at 1 day, 1,2 week, 1 month and every month until the silicone oil was removed. Silicone removal was done if complications (intraocular pressure increased, RD with macula on) occurred . Uncorrected visual acuity, intraocular pressure, slit lamp examination, indirect ophthalmoscopy (specially attention in: bubble, perisilicone proliferation, and emulsification). In all patients vitreous base was removed, epiretinal membrane peeling was done and 4 to 5 ml of fluorinated silicone oil was injected.
Results: :
Nine eyes were included. Seventy seven percent of cases had 1 to 3 failed previous surgery. One patient still has the silicone but an inferior redetachment with macula off is present . In 5 patients silicone removal was done at 3 months of follow up. In 3 patients the silicone was removed at 1° month. Low density silicone oil was required. Complications were: Retinal redetachment (2 patients), intraocular pressure increased [4 patients, (3 control with treatment and one did not response to treatment)], silicone in anterior chamber in one case and electroretinogram depression in one case. .
Conclusions: :
Only 55% of cases have anatomical success. More complications were seen than benefits. Fluorinated silicone oil removal is more difficult than the low density silicone oil.
