棘阿米巴角膜炎是戴角膜接触镜的并发症之一。随着角膜接触镜的广泛应用,其发病率逐年增多。主要感染途径是接触棘阿米巴污染的土壤、水、空气和角膜接触镜等。患者有异物感,视力模糊,流泪,羞明,并常有严重疼痛。病程大多缓慢,但也有数日即发展为典型表现者。用常规方法难以检出棘阿米巴,须用特殊检查方法。迄今尚无特效药物,可用抗阿米巴药物联合角膜移植术,或用角膜冷冻疗法联合角膜移植术。这类角膜炎病情险恶,病变早期常易误诊,故有造成眼部严重损害的潜在危险。 Acanthamoeba keratitis is one of the complications of wearing contact lenses.
