PURPOSE
To describe a case of Acanthamoeba infection of the cornea after radial and astigmatic keratotomy.
METHODS
A 29-year-old man developed ulcerative keratitis in the right eye 6 weeks after uncomplicated radial and astigmatic keratotomy.
RESULTS
Three sets of corneal cultures for bacteria and fungi were negative. Culture on non-nutrient agar grew Acanthamoeba organisms. Clinical improvement occurred after topical antiamebic therapy was instituted.
CONCLUSIONS
Incisional keratotomy may predispose the cornea to delayed-onset infectious keratitis. Acanthamoeba should be considered as a possible cause of infection and should be cultured for in refractory cases.
目的
描述一例放射状角膜切开术和散光性角膜切开术后棘阿米巴角膜炎病例。
方法
一名29岁男性在无并发症的放射状角膜切开术和散光性角膜切开术后6周，右眼发生溃疡性角膜炎。
结果
三组角膜细菌和真菌培养均为阴性。非营养琼脂培养长出棘阿米巴生物体。局部抗阿米巴治疗后临床症状改善。
结论
切口性角膜切开术可能使角膜易患迟发性感染性角膜炎。棘阿米巴应被视为感染的可能原因，在难治性病例中应进行培养。
