International Journal of Ophthalmology(English edition) 2013年第2期6卷 198-203页

作者： Shan-Shan Yang Tao Jiang Department of Ophthalmology the Affiliated Hospital of Medical College Qingdao University

AIM: To evaluate the efficacy of surgical treatment of vitrectomy combined with silicone oil tamponade in the treatment of severely traumatized eyes with the visual acuity of no light perception (NLP).METHODS: This was a retrospective uncontrolled interventional case-series of 19 patients of severely traumatized eyes with NLP who underwent vitrectomy surgery at the Affiliated Hospital of Medical College, Qingdao University (Qingdao, China) during a 3-year period. We recorded perioperative factors with the potential to influence functional outcome including duration from the injury to intervention; causes for ocular trauma; open globe or closed globe injury; grade of vitreous hemorrhage; grade of endophthalmitis; grade of retinal detachment; size and location of intraocular foreign body (IOFB); extent and position of retinal defect; grade of proliferative vitreoretinopathy (PVR); type of surgery; perioperative complications and tamponade agent. The follow-up time was from 3 to 18 months, and the mean time was 12 ***: After a mean follow-up period of 12 months (3-18 months) 10.53% (2/19) of eyes had visual acuity of between 20/60 and 20/400, 52.63% (10/19) had visual acuity less than 20/400 but more than NLP, and 36.84% (7/19) remained NLP. Visual acuity was improved from NLP to light perception (LP) or better in 63.16% (12/19) of eyes and the rate of complete retinal reattachment was 73.68% (14/19). Good visual acuity all resulted from those patients of blunt trauma with intact eyewall (closed globe injury). The perioperative factors of poor visual acuity prognosis included delayed intervention; open globe injury; endophthalmitis; severe retinal detachment; large IOFB; macular defect; a wide range of retinal defects andsevere ***: The main reasons of NLP after ocular trauma are severe vitreous hemorrhage opacity; refractive media opacity; retinal detachment; retinal and uveal damages and defects, especially defects of the macula; PVR and endopht

AIM:To evaluate outcomes and determine factors influencing the outcomes of vitrectomy with silicone oil(SO)endotamponade for the management of rhegmatogenous retinal detachment(RRD)complicated by advanced proliferative vitreoretinopathy(PVR).METHODS:This is a retrospective,interventional case series of eyes with PVR grade C associated RRD with or without prior surgery that underwent vitreoretinal surgery and SO *** with a minimum follow-up of 6mo after SO extraction were *** were classified into three PVR subgroups according to severity and extension of *** influence of several preoperative,intraoperative and postoperative factors upon the functional and anatomical outcomes was assessed using multivariate logistic regression ***:A hundred and one eyes of 101 patients that met the inclusion criteria were ***-five of 101 eyes(74.3%)had successful retinal reattachment after one *** aqueous cell and flare at the first week exam had a statistically significant association with redetachment,recurrent membrane proliferation and *** acuity improvement was significantly associated with faint postoperative aqueous inflammation values,primary vitrectomy and PVR outside of the posterior ***:Although encouraging anatomical and functional outcomes are achieved after vitrectomy and SO tamponade in eyes with RRD complicated by PVR,an increase in aqueous flare or cells at the first week follow-up is most likely to result in postoperative late *** vitrectomy,PVR associated with minimal posterior pole extension and absent to mild postoperative aqueous inflammation are associated with improved post-operative final visual acuity.

AIM: To identify the predictive factors and laser photocoagulation associated with the use of silicone oil as endotamponade during primary diabetic vitrectomy. METHODS: The medical and surgical records of 690 patients(798 eyes) who underwent primary diabetic vitrectomy at a tertiary eye hospital in China from January 2018 to December 2018 were reviewed in this retrospective cohort study. The patients’ baseline characteristics and preoperative treatments were recorded. The binary Logistic regression model was used to evaluate the risk factors for the use of silicone oil as endotamponade agent during primary vitrectomy for proliferative diabetic retinopathy(PDR)-related ***: Among 690 patients with mean age of 52.1±10.5 y(range: 18-85 y), 299/690(43.3%) were female. The 31.6% of the eyes received preoperative laser treatment, and 72.4% of the eyes received preoperative anti-VEGF adjuvant therapy. Non-clearing vitreous haemorrhage(VH) alone or combined with retinal detachment was the main surgical indication(89.5%) for primary vitrectomy. silicone oil was used as endotamponade in 313(39.2%) eyes. Lack of preoperative laser treatment [odds ratio(OR) 0.66, 95% confidence interval(CI): 0.48-0.92;P=0.015] and older age(OR 0.96, 95%CI: 0.95-0.98;Psilicone oil tamponade during primary vitrectomy for PDR. CONCLUSION: The lack of preoperative laser treatment is a significant predictor of silicone oil tamponade during primary vitrectomy for PDR. However, the severity of PDR relevant to silicone oil use should be further evaluated.

A silicone sponge sutured directly across the macular region was performed on the silicone oil filled eyes. silicone oil was removed no sooner than 1 month post- EMB. The duration of follow -up time after removal of silicone oil was more than 3 ***: Retinas of five eyes were all reattached at the last follow-up. The postoperative vision ranged from counting fingers to ***: Anatomical results improved after EBM for posterior retinal detachment in silicone oil filled eyes associated with myopic macular hole, which was not evident for visual outcome.
