Ptosis occurs in a variety of disorders including myasthenia gravis, oculomotor palsy, Horner's syndrome and brain stem disorders. There are also supranuclear lesions causing blepharoptosis. The latter disorders are reflex blepharospasm, apraxia of eyelid opening and Meige's syndrome. Since the total number of bilateral ptosis associated with cerebral hemispheric lesions is very few, whether the responsible lesions are located in the nondominant hemisphere or bilateral hemispheres are still controversial. We report here a case of bilateral cerebral ptosis that occurred in association with cerebral infarction of the nondominant hemisphere.
上睑下垂发生于多种疾病，包括重症肌无力、动眼神经麻痹、霍纳综合征和脑干疾病。也有引起睑下垂的核上性病变。后者包括反射性眼睑痉挛、眼睑开合失用症和梅杰综合征。由于与大脑半球病变相关的双侧上睑下垂总数很少，因此责任病变是位于非优势半球还是双侧半球仍存在争议。我们在此报告一例与非优势半球脑梗死相关的双侧大脑性上睑下垂病例。
