We report a case of congenital mydriasis in a neonate with megacystis microcolon intestinal hypoperistalsis syndrome (MMIHS). Pilocarpine testing and gastrointestinal pathology in our patient suggest that the mydriasis is due to an underlying smooth muscle myopathy of the iris sphincter muscle. These findings may have important implications regarding the pathogenesis of MMIHS.
我们报告了一例患有巨膀胱-小结肠-肠蠕动不良综合征（MMIHS）的新生儿先天性瞳孔散大病例。我们患者的毛果芸香碱试验和胃肠道病理学检查提示，瞳孔散大是由于虹膜括约肌平滑肌肌病所致。这些发现可能对 MMIHS 的发病机制具有重要意义。
