白內障手術後之尼龍縫線引起的毒性反應―壹病例報告
Nylon Suture Toxicity after Cataract Surgery
摘要
白內障手術後之尼龍縫線引起的毒性反應是很少見的，我們在此報告一個病例。病人為一47歲男性，有10年以上的糖尿病及癲癎病史，未曾接受過眼部手術。病人於1992年6月11日在本院接受右眼囊外白內障摘除手術及植入人工水晶體(ECCE+PCIOL)，並且以10-0尼龍縫線作間斷縫合。術後三週，病人右眼出現異物感及流淚等症狀。理學檢查發現，上方輪部呈厲害之結膜充血，沿著縫線附近的結膜有局部浸潤及糜爛，並有鞏膜凹陷的現象。細菌學檢查結果為陰性反應。病人在完全折線後，以上症狀迅速緩解，縫線部位外觀恢復正常，也無發炎現象。故推測為尼龍縫線引起之毒性反應。我們將探討其發生的可能原因，並作文獻上的回顧。

Nylon suture toxicity is a rare complication of cataract surgery. We report a 46-year-old patient had a history of DM and epilepsy for more than 10 years without any ophthalmic surgery previously. This patient underwent planned extracapsular cataract extraction (ECCE) with posterior chamber IOL implantation on June 11, 1992. The wound was closed by interrupted 10-0 nylon suture. Three weeks later, the patient returned complaining of foreign body sensation and tearing. Physical examination revealed severe superior limbic conjunctival hyperemia, conjunctival infiltrates and erosion localized to the wound, and scleral excavation undederlying the 10-0 nylon suture. Bacteriological study was negative. After removed all sutures, these signs and symptoms subsided quickly. So it was diagnosed nylon suture toxicity. We discuss the clinic characterics and etiology of this postoperative complication.
