Retinal detachment surgery with silicone oil injection in transconjunctival sutureless 23-gauge vitrectomy

Abstract

Purpose: To report a surgical technique for retinal detachment surgery using transconjunctival sutureless 23-gauge vitrectomy with silicone oil injection. Methods: Thirty-one patients with retinal detachment underwent vitreoretinal surgery using a transconjunctival sutureless 23-gauge vitrectomy system. At the end of the procedure silicone oil was injected into all eyes through a microcannula. After removing the microcannula, a bipolar cautery was used in the conjunctiva over the wound to prevent silicone oil reflux. Results: In all patients retinal reattachment and injection of silicone oil through transconjunctival sutureless 23-gauge vitrectomy system was possible. Retinal re-detachment occured in 8 patients (25.80%)who were submitted to a new vitreoretinal surgery by the technique describe above, however, more extensive retinotomy was necessary in all cases, specially inferiorly. Three patients (9.67%) presented silicone oil leakage in subconjuntival compartment. Another surgical procedure was necessary to remove the subconjuntival silicone oil. Conclusions: The retinal detachment surgery with silicone oil injection in transconjunctival sutureless 23-gauge vitrectomy is a safe and efficient technique to repair retinal detachment and it has the advantage of being minimally invasive.
