Analysis of the possibility for long-term intraocular silicone oil tamponade

Abstract

Objective To study the etiology,symptoms and prognosis of long-term intraocular silicone tamponade.Methods This study collected 23 patients (23 eyes) with intraocular silicone oil tamponade for more than 3 years during 8 years follow-up.Male was 16; female was 7; the time of silicone oil tamponade was from 3 to 15 years,including 16 eyes of rhegmatogenous retinal detachment; 2 eyes of acute retinal necrosis; 2 eyes of proliferative diabeticretinopathy; 3 eyes of traumatic ocular rupture.All patients had been performed vitrectomy and silicone oil tamponade,including 6 eyes with retinal incision and 17 eyes with lesectomy.Results Of 17 eyes with long-term silicone oil tamponade,including 7 eyes with retina reattached successfully,7 eyes with retinal detachment locally; 2 eyes with total retinal detachment; 1 eye without light perception.Six eyes performed silicone oil removal,including 5 eyes with retinal reattachment after silicone oil removal,1 eye with recurrent retinal detachment.Visual acuity of patients was 0.01 to 0.06 in 6 eyes; 10 eyes with light perception to the figure count; 3 eyes with no light perception.The complications included band-shaped degeneration of cornea,bullous keratopathy,secondary glaucoma,silicone oil emulsification,cataract,atrophy of optic nerve,intraocular hypotension,rubeosis iridis and silicone oil into the subretinal.Conclusions Silicone oil tamponade will lead to long-term abnormal structure and function of the tissues of the eye,however,for severe vitreoretin.opathy cases with retinal detachment,silicone oil tamponade can maintain long-term retinal reattachment,prolong the visual function,keep eye appearance.
