Abstract

Impact of Duration of Silicone Oil Tamponades on Surgical Success after Removal

Purpose: To evaluate the influence of duration of silicone oil tamponades after vitrectomy due to proliferative vitreoretinopathy (PVR) with retinal detachment on the anatomical and functional outcome after removal of oil.
Method: 114 consecutive patients with retinal detachment due to PVR were treated with circumferential buckling, vitrectomy and silicone oil tamponade. After the removal of oil patients were followed up for 6 months. According to the duration of oil tamponade 4 groups were defined (group 1: 5-6 months; group 2: >6-12; group 3: <12-18 months; group 4: >18 months). Only in case of a stable retinal situation oil had been removed early (group 1). Anatomical success was defined as total retinal attachment posterior from the equator 6 months after oil removal. Visual acuity and intraocular pressure were recorded as functional parameters.
Results: Within the 4 groups preoperative risk factors (age, size of retinal detachment, stage of PVR) were equally distributed. In all cases a total retinal reattachment could be achieved by silicone oil tamponade. The cumulative probability of anatomical success 6 months after removal of oil was similar in group 1 – 4 (86.1%, 87.6%, 87.4%, 86.6%; log rank= 0.794). The course of intraocular pressure (p= 0.169) and visual acuity (p= 0.077) revealed no significant differences within the 4 groups.
