Then IOFBs were approached and backsiphoned by using self-made backsiphon syringe needles which were selected according to the size and shape of IOFBs. The IOFBs are removed with the inflow of sodium hyaluronate naturally surging into the needles.Results: Posterior polar IOFBs in 13 cases (13 eyes) were all removed successfully at one time. There were no accidental injuries or complications. The postoperative vision in 11 cases (11 eyes) was improved, unchanged in 1 case (1 eye) and decreased in 1 case ( 1 eye).Conclusions: The technique using viscoelastics to dissociate, suspend and backsiphon IOFBs during the removal of the posterior polar IOFBs can evidently decrease operative difficulty, injury and complications.展开更多

METHODS:Thirty-six patients of MIOFD with endophthalmitis accorded with Exclusion and inclusion criteria were retrospectively analyzed. A detailed analysis of the patients' natural factors, preoperative examinations, intraoperative endotamponades choice, postoperative complications and therapeutic effects was performed. RESULTS: BSS was used in 4 eyes without obvious retinal damage. There was no postoperative complication and their visual acuity (VA) was improved. Sixteen eyes that had mild retinal damage filled with C3F8 gas. The postoperative VA improved in 10 eyes (62.5%), 4 eyes (25.0%) remained unchanged and 2 eyes (12.5%) decreased. Only 2 cases occurred postoperative retinal detachment in gas group. Another 16 eyes with serious retinal damage were treated with silicone oil. Postoperative VA of 9 eyes (56.3%) improved, 3 eyes (18.8%) remained unchanged and 4 eyes (25.0%) decreased. The silicone oil group had higher incidence of postoperative complications, but the incidence of secondary treatment had no significant different between silicone oil and gas group. CONCLUSION: An appropriate choice of endotamponades in vitrectomy surgery for MIOFB with endophthalmitis is important for prognosis.展开更多

目的:分析眼后段眼内异物行玻璃体切除术(pars plana vitrectormy,PPV)取出异物对视力的影响。方法:回顾性分析2015年12月至2017年1月于重庆医科大学附属第一医院眼科入院诊断为眼后段眼内异物共40例40眼,所有眼后段眼内异物均通过23G微...目的:分析眼后段眼内异物行玻璃体切除术(pars plana vitrectormy,PPV)取出异物对视力的影响。方法:回顾性分析2015年12月至2017年1月于重庆医科大学附属第一医院眼科入院诊断为眼后段眼内异物共40例40眼,所有眼后段眼内异物均通过23G微创PPV取出。研究统计了年龄、性别、术前/术后最佳矫正视力(best corrected visual acuity,BCVA),眼后段异物性质、大小,眼内异物移除时间,眼内异物进入位置,眼内异物残留位置,手术时机,手术方式和并发症等因素。结果:40例患者异物均被取出,取出率为100%,术后平均BCVA较术前平均BCVA明显增高(t=4.295,P=0.000),具有统计学意义。患者视力的主要影响因素为视网膜脱离(P=0.000)、视网膜裂孔(P=0.001)、眼内异物的大小(P=0.023)、异物取出的时间(P=0.006)、前房积血(P=0.032)、玻璃体积血(P=0.025)等。结论:更大的眼内异物、合并视网膜脱离、视网膜裂孔、前房积血、玻璃体积血、异物取出时间越长,在开放性眼外伤中会引起更严重的后果,视力预后会更差。本研究中,是否行Ⅰ期缝合+玻璃体腔内注药术或者直接行PPV联合眼球清创缝合对视力及解剖学的恢复并无显著影响,但是异物取出的早晚对视力预后有影响,PPV能够更好地取出眼内异物并发现眼内并发症,及时处理,对患者的视力恢复起重要作用。展开更多
