Comparative analysis of two groups of patients according to the results of cataract phacoemulsification in combination with silicone oil removal through flat part of the ciliary body and posterior capsulorhexis in the long term after retinal detachment surgery

Purpose. To conduct a comparative analysis of two groups of patients according to the results of cataract phacoemulsification in combination with the silicone oil removal through flat part of the ciliary body and posterior capsulorhexis in the long term after retinal detachment surgery. Material and methods. 30 patients with a diagnosis of cataract, avitria, tamponade of the vitreous cavity with silicone oil OXANE 5700 were under observation. Patients were randomly divided into two groups. In both groups, the infusion system was installed through port 25 Ga located 3–4 mm from the limb, cataract phacoemulsification was performed in the first stage. In the first group (15 patients), silicon oil was removed through the posterior capsulorexis using a curved aspiration cannula of caliber 18 Ga. In the second group (15 patients) silicon oil was removed using aspiration through the second port of 25 Ga. The assessment of the functional and anatomical state after surgery was based on data from visometry, autorefractometry, ultrasound B-scanning of the vitreous cavity, and optical coherence tomography of the macular area. Assessment of patient satisfaction with the subjective level of quality of life was carried out using the validated visual function questionnaire Visual Function (VF-14). Results. In both groups, on average, there was a significant increase in the best corrected visual acuity. According to B-scan data, emulsified silicone oil particles were less detected in patients after removal of silicone oil through posterior capsulorexis. The subjective level of quality of life of each patient improved significantly in both groups. Conclusion. Performing the combined operation of cataract phacoemulsification with the removal of silicone oil through the posterior capsulorhexis in comparison with the silicone oil removal through the flat part of the ciliary body can equally improve visual function. Satisfaction with treatment results was slightly higher in the group with silicone oil removal through posterior capsulorexis. Key words: cataract, avitria, silicone oil, posterior capsulorexis.

Abstract Background To investigate the long-term outcomes and complications of scleral-fixated intraocular lens (SFIOL) implantation without conjunctival peritomies and sclerotomy in patients with a history of ocular trauma with inadequate capsular support during primary pars plana vitrectomy or silicone oil removal. Methods Records of ocular trauma patients who underwent implantation of SFIOL without conjunctival peritomies and sclerotomy during primary pars plana vitrectomy or silicone oil removal. Results Sixty-nine eyes of 69 patients were included in this study. The median follow-up period was 34 months (range, 6-99 months). The average patient age at the time of surgery was 44 years old (range, 4-80 years). At the end of follow-up, the preoperative mean of best corrected visual acuity (BCVA) was 0.79 ± 0.86 log of the minimum angle of resolution (logMAR), which improved 0.20 ± 0.26 logMAR postoperatively (P = 0.01). BCVA improved or remained unchanged in 64 eyes (92.8%), VA decreased two lines in five eyes (7.2%). Early postoperative complications included transient corneal edema in seven eyes (10.1%), minor vitreous hemorrhage in four eyes (5.8%), transient elevated intraocular pressure (IOP) in one eye (1.4%), and hypotony in three eyes (4.3%). Late postoperative complications included persistent elevated IOP in five eyes (7.2%), epiretinal membrane formation in three eyes (4.3%), and cystoid macular edema noted in one eye (1.4%). Conclusion Use of a scleral-fixated intraocular lens implantation without conjunctival peritomies and sclerotomy in ocular trauma patients during either primary pars plana vitrectomy or second silicone oil removal is a valuable approach for the management of traumatic aphakia in the absence of capsular support.

Purpose.To evaluate the effects of long-term tamponade with silicone oil on retinal saturation.Methods.A total of 49 eyes that received tamponade with silicone oil were included. The patients were divided into 3 groups (3–6 months, 6–9 months, and >9 months) according to the duration of silicone oil tamponade. Retinal oximetry was performed using the Oxymap system before and 2 months after silicone oil removal.Results.The mean retinal oxygen saturation before silicone oil removal was 107% ± 12% in the arterioles and 60% ± 10% in the venules, with an overall arteriovenous difference (AVD) of 47% ± 14%. The AVD in the >9-month group was significantly higher than that in the 3–6-month group (54% ± 16% versus 44% ± 11%,P=0.042). After silicone oil removal, the AVD in the >9-month group was significantly decreased (45% ± 9% versus 54% ± 16%,P=0.009); additionally, the arterioles were significantly wider than before surgery (10.8 ± 0.7 pixels versus 10.4 ± 0.9 pixels,P=0.015).Conclusions.The tamponade with silicone oil for more than 9 months will cause the alterations of retinal saturation and the narrowing of retinal arterioles, which may further interfere with the oxygen metabolism in the retina.

Silicone Oil Tamponade

Introduction: Silicone oil is the preferred tamponade agent used in pars-plana vitrectomy for retinal detachment when a long duration of endotamponade is intended. Due to its possible long-term complications, removal of silicone oil (ROO) is recommended. Purpose: This study is done to evaluate the mean duration and complications of silicone oil tamponade, and the anatomical and visual outcomes after silicone oil removal. Study design: Retrospective study. Materials and methods: Retrospective review was done on 55 eyes of 55 patients, in which ROO was carried out at Hospital Sultanah Bahiyah in 2016 with a minimum six months follow-up postoperatively. Results: The duration of silicone oil tamponade in these eyes ranged from 1.0 to 55.5 months, with mean duration of 10.8 months (SD 7.74). Common complications of silicone oil tamponade observed were cataract in 30 eyes (54.5%), followed by secondary high intraocular pressure in 6 eyes (10.9%), and band keratopathy in 3 eyes (5.5%). Six eyes (10.9%) developed retinal re-detachment after oil removal. The majority in the anatomically attached group post ROO (40 eyes, 81.6%) showed improvement of vision after ROO, with mean best corrected vision of LogMAR 1.38 (6/150) with silicone oil in situ to LogMAR 0.88 (6/48) at the latest follow-up. Conclusions: Although the recommended duration of silicone oil tamponade ranges from three to six months, the optimal timing for silicone oil removal still remains unknown. ROO is recommended due to oil-related complications, but the anatomical outcome should be evaluated as well. However, in our setting, with limited resources and time, and increasing number of patients indicated for silicone oil, it is impossible to comply with the recommended time for ROO and the timing is usually set on an individual basis.
