Densiron® 68 Heavy Silicone Oil As A Short-Term Intraocular Tamponade For Macula-On Inferior Retinal Detachments - A Case Series

Purpose: To describe the treatment outcomes and prognostic factors of retinotomy/retinectomy for rhegmatogenous retinal detachment (RD) complicated anterior inferior proliferative vitreoretinopathy (PVR). Methods: Retrospective, nonrandomized, single-center case series. The outcomes of 126 cases of retinotomy/retinectomy for RD complicated by advanced (Grade C) anterior inferior PVR managed consistently by one surgeon during a 15-year period were evaluated. Results: Forty-two eyes (33%) had primary RDs and 84 (67%) had recurrent RDs. The extent of retinotomy/retinectomy varied: 90° in 21 eyes (17%), >90° to <180° in 49 eyes (39%), and ⩾180° to ⩽240° in 56 eyes (44%). The retinotomy/retinectomy location was peripheral in 58 eyes (46%) and equatorial in 68 eyes (54%). The mean follow-up period was 43 ± 42 months. The silicone oil (SO) was removed from 98% of the eyes. The single-operation success rate after the primary retinectomy was 87%, and the final attachment rate was 94%. Visual acuity improved from 20/630 to 20/160 ( p < 0.001). Vision ⩾20/200 was achieved in 101 eyes (80%). Good visual outcome was correlated positively with preoperative VA ( p = 0.02), previous vitrectomy with gas tamponade ( p = 0.007), and was negatively correlated with number of previous RD operations ( p = 0.01), larger extent of RD ( p = 0.02) and more extensive retinotomy/retinectomy ( p = 0.04). Conclusions: An appropriate and timely intervention, including vitrectomy alone, inferior relaxing retinotomy/retinectomy and standard SO tamponade provide satisfactory outcomes for RDs complicated by PVR. Lesser extension of grade C PVR at baseline, such as PVR limited to one quadrant should encourage vitreoretinal specialists to consider retinotomy/retinectomy at a milder clinical stage of PVR development.

Purpose: Silicone oil (SO) is often used as an intraocular tamponade in repairs of retinal detachments. It may be associated with complications such as cataract, glaucoma, keratopathy, subretinal migration of oil, fibrous epiretinal and sub retinal proliferations, and oil emulsification. The purpose of this report is to describe a rare phenomenon of intraocular silicone oil migration into the cerebral ventricles, which may later be mistaken for intraventricular hemorrhages on neuroimaging. Methods: Case report with literature review. Results: A patient with a history of retinal detachment repair with intraocular SO presented with headaches. Neuroimaging revealed SO migration to the cerebral ventricles. The patient was treated conservatively with symptom management and headaches resolved. Conclusions: We present a case of intraocular SO migration to the cerebral ventricles and review the current literature. We also propose two mechanisms for this phenomenon.

AbstractA number of authors have suggested that surgery for suspected perilymph fistula is effective in preventing deterioration of hearing and in improving hearing in some cases in the short term. We present long-term hearing outcome data from 35 children who underwent exploration for presumed perilymph fistula at The Children's Hospital, Sydney, Australia, between 1985 and 1992.Methods:The pre-operative audiological data (mean of 500, 1000, 2000 and 4000 Hz results) were compared with the most recently available data (range two to 15 years) and the six-month post-operative data.Results:The short-term results showed no significant change in hearing at six months, with a subsequent, statistically significant progression of hearing loss in both operated and non-operated ears (Wilcoxon signed rank test: operated ear, p < 0.017; non-operated ear, p < 0.009).Conclusion:In this case series, exploratory surgery for correction of suspected perilymph fistula did not prevent progression of long-term hearing loss.
