问题 单项选择题 案例分析题

患儿男性,2岁,自出生起在右眼角膜颞下方,见圆形、表面光滑的黄色隆起肿物,随年龄增长,该肿物有逐渐增大趋势。

如果该肿物进一步发展,遮挡瞳孔光学区时,首选的治疗措施是()

A.成年后肿物有吸收趋势,故可暂时观察

B.局部注射血管硬化剂,使瘤体萎缩

C.可用90锶进行放疗治疗

D.肿物切除联合板层角膜移植

E.肿物切除联合羊膜移植

答案

参考答案:D

解析:较大角结膜皮样肿常可造成角膜散光,视力下降,中央部位的皮样肿遮挡瞳孔光学区,可造成患眼的弱视,因此必须及时治疗。角结膜皮样肿治疗以手术切除为主,肿物切除联合板层角巩膜移植是最理想的手术方式。因此第三问选择D。
