多数后天性共同性斜视发生于婴幼儿早期。对斜视急性发作患者,不论其年龄或原因如何,均应仔细分析以排除麻痹性偏斜。一般而言,急性内斜视为共同性,无外展不足,已被认为是良性原因所致,不伴有颅内疾病。本文6例患儿,起初表现为急性共同性内斜视,而后却发现有脑干或小脑肿瘤。6例中,男4例女2例,发病年龄为3.1岁～10.4岁。均有清楚的发作病史,除1例年龄小不能诉说外,5例有复视。斜视角为15～35△(棱镜度)。4例远视眼,给以睫状肌麻痹剂后,1例内斜视角从25△减少到15△,3例远视矫正后内斜视偏斜无改变,视力矫正后眼运动融合均未恢复。虽有2例神经放射学检查见轻度脑积水,但未见视乳头水肿。3例有眼球震颤。6例中4例为小脑星形细胞瘤,
Most acquired common strabismus occurs in infants and young children. Patients with acute episodes of strabismus, regardless of age or cause, should be carefully analyzed to rule out paralytic bias. In general, acute esotropia as a common, lack of outreach, has been considered due to benign causes, not associated with intracranial disease. This article 6 cases of children, initially manifested as acute common esotropia, and later found to have brain stem or cerebellar tumors. 6 cases, 4 males and 2 females, the age of onset was 3.1 years old to 10.4 years old. Have a clear history of seizures, in addition to 1 case of young age can not tell, 5 cases of diplopia. Squint angle of 15 ~ 35 △ (prism degrees). 4 cases of hyperopia, given cycloplegic agent, 1 case of oblique angle decreased from 25 △ 15 △, 3 cases of farsightedness correction of esotropia skew no change, corrected visual acuity were not restored ocular movement. Although there are 2 cases of neuroradiological examination showed mild hydrocephalus, but no papilledema. 3 cases had nystagmus. Of the 6 cases, 4 were cerebellar astrocytoma,
