{"title":"Intraocular silicone oil removal: timing, outcome, and silicone oil complications encountered","authors":"Nurul Shima Ismail, L. Phang, Teh Wee Min, W. H. W. Halim, H. Ali","doi":"10.35119/myjo.v1i1.20","DOIUrl":"https://doi.org/10.35119/myjo.v1i1.20","url":null,"abstract":"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. \u0000Purpose: 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. \u0000Study design: Retrospective study. \u0000Materials 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. \u0000Results: 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. \u0000Conclusions: 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. \u0000 ","PeriodicalId":405983,"journal":{"name":"Malaysian Journal of Ophthalmology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124472763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is no evidence on the effect of cigarette smoking as a risk for primary angle-closure glaucoma (PACG). \u0000Purpose: To determine the association between cigarette smoking and PACG in Malay patients. \u0000Study design: Case control study. \u0000Materials and methods: Two-hundred Malay PACG patients and 250 controls from  three tertiary hospitals in Malaysia were involved in this study. PACG patients were diagnosed based on the World Glaucoma Association consensus. The smoking status was documented using validated questionnaire adopted from Singapore Malays Eye Study through face-to-face interview. Smoking status was divided into active smokers, ex-smokers, passive smokers, and non-smokers. The association of smoking and PACG was analysed with multiple logistic regression. Confounders such as age, gender, education status, and body mass index (BMI) were considered in the analysis. \u0000Results: There was female preponderance in PACG with 3:1 ratio. Active smokers (p = 0.656) and ex-smokers (0.073) were not significantly associated with PACG in Malays. Passive smoking significantly increased the risk of PACG by 6.8-fold (95% CI 2.49,18.67; p < 0.001). Number of cigarettes/day (p = 0.144) and duration of smoking (p = 0.176) were also not significantly associated with PACG (p = 0.144). No formal education, primary and secondary education level increased the risk of PACG (p < 0.001). Each unit increment of BMI increased the risk of PACG by 1.14-fold (95% CI 1.03, 1.27; p = 0.014). A year increased in age increased the risk by 1.05 times (95% CI 1.00, 1.09; p = 0.026). \u0000Conclusions: There is no significant association between active smoking and PACG. Passive smoking is a potential risk factor for PACG. The preponderance of women may contribute to this result. However, quantification of exposure to passive smoking is not possible in this study.","PeriodicalId":405983,"journal":{"name":"Malaysian Journal of Ophthalmology","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123835556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We set out in this study to investigate the relationship between the two parameters by using anterior segment optical coherence tomography (AS-OCT). \u0000Purpose: To evaluate anterior segment and lens parameters associated with IOP lowering after phacoemulsification. \u0000Study design: Prospective longitudinal single centre study. \u0000Materials and methods: All consented study participants underwent uneventful phacoemulsification with foldable intraocular lens implantation. IOP measurement, gonioscopy, and AS-OCT measurements were performed pre- and postoperatively at one month. Customised software (Zhongshan Angle Assesment Programme, ZAAP) was used to measure various anterior chamber parameters. A-scan biometry was used to measure axial length (AL), lens thickness (LT), and to calculate lens position (LP) and relative lens position (RLP). \u0000Results: Eighty-six eyes from 86 patients were included in this study. The mean IOP reduced significantly after phacoemulsification (from 16.2 ± 2.4 mmHg to 14.1 ± 2.6 mmHg at one week and 14.4 ± 2.3 mmHg at one month, P < 0.001). In the multivariate regression model, preoperative IOP and AL were the only significant parameters associated with percentage change in IOP (p < 0.001). \u0000Conclusion: Change in IOP post-phacoemulsification is dependent on preoperative IOP and AL. Greater percentage change in IOP is seen in eyes with shorter axial length.","PeriodicalId":405983,"journal":{"name":"Malaysian Journal of Ophthalmology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130299234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
