眼内异物246例视力结果临床分析

Visual outcome of 246 cases(258eyes)with intraocular foreign body extracted byconventional and vitrectomy methods

本文通过对１９８６—１９９６年收治的眼内异物病例的临床分析，探讨手术术式的选择、手术时机及影响视力预后的因素。方法：对２４６例（２５８眼）眼内异物做回顾性的分析，并对两种术式（传统法及玻切法）的视力预后进行比较。结果：眼内异物取出率１００％，一次取出成功率传统法为７８．７％（５９／７５），玻切法为９９．５％（１８２／１８３），而玻切法术后视力增加和脱盲率均优于传统法。结论：玻璃体手术的应用有利于提高眼内异物摘出率，并可同时治疗伴有的严重并发症（牵引性网脱。

urpose:To evaluate the factors which may affect visual prognosis by analvzing clinical data of patients with intraocular foreign body treated during 1986—1996。Methods:246 cases(258 eyes)were studied retrospectively.The intraocwlar foreign bodies were removed by either conventional or vitrectomy surgery,Results:The first operation was successful in 182 out of 183 eyes(995%)in the vitrectomy group while only 59 out of 75 eyes(787%)in the conventional one(P<005).The foreign bodies were extracted in all eyes(100%)by surgery no more than 3 times.The vision was significantly improved following vitrectomy with removal of the foreign body(P<0001).In the contrast,the vision improvement was not significant in the conventional group(P>005).The visual results were strongly dependent on the size of foreign body,location of wound cntry and time of foreign body being in the eye.Conclusion:vitrectomy is a more reliable way to deal with intraocular foreign body and to restore vision especially when complicated vitrcorctinal conditions exist.
