HIGH-DENSITY SILICONE OIL DENSIRON-68 AS AN INTRAOCULAR TAMPONADE FOR PRIMARY INFERIOR RETINAL DETACHMENTS

Abstract

To evaluate the effectiveness and safety of the heavy silicone oil Densiron-68 as an internal retinal tamponade after vitrectomy in patients with primary inferior rhegmatogenous retinal detachment. A retrospective consecutive case series involving inferior rhegmatogenous retinal detachment in 42 patients recruited between 2007 and 2010 was completed. All patients underwent primary vitrectomy followed by injection of Densiron-68. Each patient was then examined at 1 week, 1 month, 3 months, and 6 months after its removal. Included patients had a rhegmatogenous retinal detachment with at least 1 retinal break between 4 and 8 clock hours and completed 6 months of follow-up after removal of Densiron-68. Assessments for reattachment of the retina, visual acuity, and any complications from the surgery were recorded. Thirty-nine of 42 patients completed all follow-up visits. Anatomical success was achieved in 85% (33 of 39) of cases with one procedure, increasing to 95% (37 of 39) with additional surgery. The mean visual acuity improved from mean logarithm of the minimum angle of resolution of 1.29 ± 0.61 preoperatively to 0.87 ± 0.67 postoperatively. The most common complications were cataracts (83%, 10 of 12), posterior capsular opacification (22%, 6 of 27), and ocular hypertension (15%, 6 of 39). High anatomical success rates can be achieved with primary vitrectomy for inferior rhegmatogenous retinal detachment with the use of Densiron-68.
