Risk Factors for Redetachment and Worse Visual Outcome after Silicone Oil Removal in Eyes with Complicated Retinal Detachment

Purpose The goal of this study was to identify risk factors for redetachment and/or a worse visual outcome after silicone oil removal (SOR) for complicated retinal detachment. Methods The authors retrospectively analyzed 287 consecutive eyes with SOR between January 1999 and December 2003. Results Anatomic success after SOR was achieved in 81% of the eyes. The overall anatomic success at the end of follow-up was 94%. Postoperative ocular hypertension was found in 8% of the eyes, hypotony in 6% of the eyes, and keratopathy in 29% of the eyes. After SOR 43% of the eyes had an improvement in visual acuity of at least two Snellen lines. After multivariate analysis, male sex, the presence of preoperative rubeosis, and proliferative diabetic retinopathy (PDR) were found to be risk factors for recurrent retinal detachment. Male sex, preoperative visual acuity of <0.1 Snellen lines, PDR, the performance of three more operations, any size of retinectomy, and hypotony were found to be associated with a poor visual outcome of Snellen visual acuity <0.1. Conclusions Retinal detachment after SOR in the current unselected series of eyes occurred in approximately 20%, which is comparable to the Silicone Oil Study reports, published approximately 20 years ago. However, preoperative selection was then made, and less than 50% of the silicone oil-filled eyes had SOR. The higher overall anatomic success in the current study may be due to improved vitreoretinal surgical techniques.

Introduction: Pars plana vitrectomy in combination with intraocular tamponade with silicone oil is a standard technique in the treatment of complex retinal detachment. Although the use of silicone oil has improved the results of retinal detachment surgery, its removal is recommended due to the ocular complications related to its long term use. However, retinal redetachment can occur after silicone oil removal. Objective: To evaluate the anatomical and visual outcome after silicone oil removal (SOR) in eyes with complicated retinal detachment. Material and Methods: We retrospectively analyzed 64 eyes of 64 consecutive patients of silicone oil removal over a period of 12 months. All eyes had undergone standard 3 ports pars plana vitrectomy with silicone oil placement for complicated retinal detachment. Cases that completed at least 1 month follow up duration after SOR were included in the study. Anatomical success after SOR was achieved in 56 of 64 eyes (87.5%). Seven of 8 redetachments (87.5%) were seen in eyes with silicone oil tamponade duration of less than 6 months. Visual acuity improved or was stabilized in 49 of 64 eyes (76.6%). Using paired T-test, it was found that there was no significant difference in pre and post SOR visual acuity. Postoperative ocular hypertension, corneal decompensation, band shaped keratopathy and hypotony was observed in 9.4%, 4.7%, 6.4% and 21.9% respectively. Conclusion: Although there was no significant improvement in visual acuity, redetachment and complication rates were comparable to other studies. The duration of endotamponade was not significantly associated with the redetachment rate. Key words: Silicone oil removal, Redetachment, Visual outcome, Keratopathy, ocular hypertension.

Anatomic Success

Background. To review the pattern of retinal detachment (RD) in patients with choroidal coloboma and type of reattachment surgery performed and to study its outcome in terms of retinal reattachment, visual acuity, and postsurgical complications. Methods. Observational case series of a single tertiary eye institution of 13 eyes having choroidal coloboma with RD done from January 2015 to June 2017. Results. Mean age of presentation was 29.3 years (Range 14–60 years). Males were two times more affected than females (2.25 : 1). The overall rate of anatomic success achieved after RD repair and silicon oil removal at 6 months was 92.3% (12/13 eyes). Following surgery, visual acuity improved in 6 out of 11 eyes (54.54%), remained unchanged in 4 eyes (36.36%), and worsened in 1 eye (9.1%). The most common complication following surgery was secondary glaucoma in 30.7% (4/11 eyes). Conclusion. The overall anatomic success rate of retina reattachment surgery in colobomatous eye is good, and the visual outcome following surgery can improve in majority of the cases or may remain same in few cases. Hence, timely surgery is advocated. But careful follow-up is required as the risk of postoperative complications is also high.

Purpose: To evaluate the surgical outcomes of Combined Phacoemulsification with IOL implantation and Silicone oil removal in patients with previous retinal surgery. Study Design: Interventional case series. Place and Duration of Study: Al-Ibrahim eye Hospital Karachi from January 2019 to December 2019. Methods: Total 30 eyes of 30 patients between ages of 25 to 65 years, who had retinal detachment surgery with silicone oil used as internal tamponade and later on developed cataract were re-operated once confirming that retinal was attached. The time interval between two surgeries was 8 to 10 months. Phacoemulsification with IOL implantationwas done followed by silicone oil removal by 23-gauge pars plana method. Postoperative follow-ups were done at day 1, 1 month and at 6 months to record visual acuity and retinal status. Results: Best corrected Visual acuity was recorded pre and post-operatively using Snellen chart. Preoperatively 12 patients had visual acuity of 6/60, 12 with vision 6/95 and 6 with 6/120. There was improvement of 2 lines of visual acuity post operatively as recorded by Snellen chart. Retina was attached in 28 (93.33%) patients and 2 (6.66%) had re-detached retina at the end of 6 months. Conclusion: Visual outcomes were found to be better with low rate of retinal re-detachment after 6 months follow-up of combined phacoemulsification with IOL implantation and silicone oil removal. Hence, Combined Phacoemulsification with Silicone oil removal is a method that is associated with better visual and anatomical outcomes as well as decrease the chances of patients undergoing third surgery for cataract extraction.

Purpose: This retrospective study recorded intraoperative findings during silicone oil removal and postoperative anatomical outcomes comparing endoscopy-assisted pars plana vitrectomy (E-PPV) vs pars plana vitrectomy (PPV) alone after proliferative vitreoretinopathy (PVR)-related retinal detachment (RD) repair. Methods: This single-center retrospective study included patients who underwent PPV for silicone oil removal after RD with PVR from July 2009 to January 2017. Patients with diabetic tractional RD, history of trauma, uveitis, or endophthalmitis were excluded. After 2013, an endoscopic visualization system (E2 MicroProbe; Endo Optiks) was used in a nonrandomized fashion. Data collection included reattachment rate, intraoperative endoscopic findings and phthisis rate. Results: Fifty-four eyes of 54 patients were included. The mean participant age was 58.4 ± 12.9 years and 36 (65.5%) participants were male. The mean (± SD) follow-up duration after oil removal was 24.3 ± 20.1 months. E-PPV combined with wide-angle visualization system was performed in 26 (48.1%) of the patients; the surgical management was modified after endoscopic examination in 17 (65.4%) of the cases. Reattachment rate in the E-PPV group was 96.2% compared with 76.0% in the PPV-alone group ( P = .04). Conclusions: E-PPV for silicone oil removal appears to be advantageous for prevention of RD recurrence, thus achieving better reattachment rates. A thorough examination is facilitated by endoscopic visualization and contributory factors for anterior PVR can be identified and treated.

Myopic Macular Hole

Purpose. To evaluate the efficacy of silicone oil (S.O) reinjection without macular buckling for treatment of recurrent myopic macular hole retinal detachment (MHRD) after silicone oil removal.Methods. A retrospective consecutive interventional study from medical reports on cases of myopic MHRD. Fifty-three eyes of 51 patients underwent silicone oil removal after successful repair of MHRD were reviewed. The main outcomes were the retinal status after silicone oil removal and management of recurrent cases.Results. The rate of recurrent RD (Re RD) after silicone oil removal was 11.3% (6 out of 53 eyes). One case refused any other interference. In the remaining 5 eyes, 4 eyes (80%) could be reattached by S.O re-injection and one eye (20%) developed Re RD after S.O re-injection. Range of followup after management of recurrence was 5–53 months (mean 18.7 months).Conclusions. This case series concluded that the risk factors for recurrent RD after silicone oil removal from cases of myopic MHRD were high myopia, open flat MH, and large posterior staphyloma. Revision of vitrectomy and S.O re-injection can reattach most of recurrent cases.
