The opportunity of vitrectomy for opening eyeball injury is one of the important factors affecting the prognosis. Anterior segment wound repaired by routine suturing needs following and continuous treatment with vitrectomy. The key technique of the following treatment should be the debridement of the inside of wound and expurgation of the surrounding tissues adjacent to the wound, and the emphasis should be put on retinal reattchment and stable repairment.
Objective To evaluate the effect of vitrectomy on traumatic retinal detachment combined with choroidal damage. Methods The data of 1075 traumatic eyes which underwent vitrectomy from 1995 to 2005 were retrospectively analyzed. Forty-one patients (41eyes, 3.8%) with different kinds of choroidal injuries, including traumatic retinal detachment combined with serous choroidal detachment, hemorrhagic choroidal detachment (including traum atic separation of choroid and sclera) or subretinal hemorrhage, underwent closed vitrectomy. The operative prognosis in different groups were analyzed statisti cally. Results The retina reattached in 38 eyes （92.7％）, in cluding 10 with the final visual acuity gt; 0.1（24.4％）；the visual acuity improved postoperatively in 29 (70.7％)，including 14 in subretinal hemorrhage group （87.5％, 14/16），12 in serous choroidal detachment group（75.0%, 12/16）and 3 in hemorrhagic choroidal detachment（33.3%, 3/9） (chi;2＝8.394, P＝0.015); amaurosis was found in 6 eyes, all of which were with hemorrhagic choroidal deta chment preoperatively. In 17 eyes with ocular hypotension, a persistent silicone oil tamponade was needed in 8（47.1％）, in which 5 were in the hemorrhagic choroidal detachement group (55.6％, 5/9). Conclusions Appropriate vitrectomy is helpful for traumatic retinal detachment combined with choroidal damage, and the operative prognosis of the patients combined with subretinal hemorrhage is good. The operative prognosis of hemorrhagic choroidal detachment is worse than that of the serous choroidal detachment. However, it doesnprime;t mean that all the hemorrhagic choroidal detachment eyes need ocular enucleation. The prognosis of eyes with severe traumatic choroidal detachment was poor, and the eyes are with ocular hypotension which needs a long-term silicone oil tamponade.

Objective To investigate the etiological factors of endophthalmitis and evaluate the outcomes of vitrectomy for endophthalmitis.Methods From January 1999 to December 2001, 53 consecutive patients (54 eyes ), 38 men and 15 women, diagnosed as endophthalmitis were retrospectively evaluated. The patients′ ages ranged from 1 year to 74 years (mean 32 years). Two patients (2 eyes) with mild inflammation received antibiotic medication therapy, 5 patients (5 eyes) with no light perception and severe inflammation underwent evisceration, and the other 46 patients (47 eyes) underwent pars plana vitrectomy. Postoperative follow-up ranged from 2 to 32 months (mean 10.5 months). Results Endophthalmitis was diagnosed as resulting from penetrating injury in 32 eyes (59.26%), endogenous endophthalmitis in 8 eyes (14.81%), cataract surgery in 7 eyes (12.96%), gl au coma surgery in 2 eyes (3.70%), vitrectomy in 3 eyes (5.56%), radial keratotomy in 1 eye (1.85%), and unknown reason in 1 eye (1.85%). The postoperative visual a cuities (VA) of these patients increased significantly (P=0.003). The VA of the patients underwent vitrectomy in 3 days was obviously better than those after 3 days (P=0.014), and the VA of the patients underwent vitrectomy in 7 days was obviously beter than those after 7 days (P=0.021). Thirty-seven eyes (68.52 %) had functional success (VA≥0.02), 47 eyes (87.04%) had anatomical success (VAlt;0.02) , and 27 eyes (50.00%) were out of blindness (VA≥0.05). Conclusions Penetrating ocular injury, especially with retained intraocular foreign bodies, is the most common cause of suppurative endophthalmitis. Vitrectomy is a good method for the treatment of endophthalmitis. (Chin J Ocul Fundus Dis，2003，19：93-95)
目的:评价皮质激素联合环孢素对比皮质激素单用防治穿透性角膜移植(PKP)术后排斥反应的疗效。方法:计算机检索PubMed,EMBASE.com,SCI,Cochrane图书馆,CBM,CNKI数据库,纳入皮质激素联用环孢素对比皮质激素单用防治PKP术后排斥反应的随机对照试验,进行方法学质量评价并应用RevMan软件进行meta分析。结果:共纳入5篇报道,1篇A级文献,B、C级各2篇。Meta结果:术后排斥反应发生情况组间差异有统计学意义(RR=0.3,95%CI 0.140.65);对既发排斥反应的逆转,组间差异无统计学意义(RR=1.15,95%CI 0.93-1.42)。结论:基于当前证据,皮质激素联合环孢素防治PKP术后排斥反应疗效并不优于皮质激素单用。
Objective To observe the clinical characteristics of severe ocular detonator explosive injuries and to evaluate the therapeutic effects of vitrectomy on it. Methods Clinical data of 37 consecutive patients (65 eyes) with severe ocular detonator explosive injuries were retrospectively analyzed. The patients included 36 males and 1 female with the average age of 28.6 years. The biocular injuriy was in 31 cases (83.8 %), and one-eyed injury was in 6 cases (16.2%). A total of 48 eyes had severe explosive injury. The visual acuity was no light perception in 9 eyes in which 3 eyeballs were obviously atrophic, light perception in 28 eyes, hand moving in 4 eyes, and counting finger/33 cm in 7 eyes. Vitrectomy was performed on 46 eyes, in which 41 had severe ocular explosive injury. There were no vitreous surgery indications in 13 eyes of 19 eyes didnprime;t undergo surgery; the other 6 eyes didnprime;t undergo surgery due to the atrophic eyeballs or economic reasons. The treating time after trauma was within 1 week in 7 patients (18.9%), 1 week to 1 month in 13 (35.2%), and more than 1 month in 17 (45.9%). The follow-up duration lasted 6 months to 2 years after operation with the average of 8.6 months. Results In 65 eyes, the occupation ratio of conjunctival foreign bodies was 66.2%; corneal foreign bodies was 46.2%; vitreous hemorrhage was 70.8%; intraocular foreign bodies (IOFB) was 69.2%; retinal shocking injury or optic nerve blasting injury was 56.9%. The visual acuity improved in 33 eyes, remained unchanged in 25 eyes, and decreased in 7 eyes. In 46 eyes which had undergone vitrectomy, IOFB injuries was in 35 eyes (76.1%); the visual acuity increased in 26 eyes (59.5%), remained unchanged in 13 eyes (28.3%), and didnprime;t cure in 7 eyes (15.2%) in which 2 eyes underwent ocular enucleation and 5 eyes were atrophic. The increasing rate of visual acuity in the patients who accepted the treatment more than 1 month after injury was low. The occupation ratio of monocular blindness was 51.4% and biocular blind was 8.1%. Conclusions Most of severe ocular explosive injuries by detonator are with IOFB. causes of the high blinding rate are late treatment and serious injury. Strengthening the diagnosis and treatment of retinal shock and optic nerve blast, and performing vitrectomy as soon as possible can improve prognositc visual function of injured eyes.
