Abstract

A 29-year-old man with vertebral defects, anal atresia, cardiac defects, tracheoesophageal fistula, renal defects, and limb defects (VACTERL) presented with headache, photophobia, and worsening nystagmus. He had near-normal visual acuity and visual fields, absent stereopsis, and see-saw nystagmus. Brain MRI revealed a thin remnant of the optic chiasm but normal-sized optic nerves. Functional MRI during monocular visual stimulation demonstrated non-crossing of the visual evoked responses in the occipital cortex, confirming achiasma. These findings have not previously been reported in VACTERL.

摘要

一名 29 岁男性,患有椎体缺陷、肛门闭锁、心脏缺陷、气管食管瘘、肾脏缺陷和肢体缺陷(VACTERL),出现头痛、畏光和眼球震颤恶化。他的视力和视野接近正常,无立体视觉,眼球震颤呈跷跷板样。脑部 MRI 显示视交叉的残余组织很薄,但视神经大小正常。单眼视觉刺激时的功能 MRI 显示枕叶皮质的视觉诱发电位没有交叉,证实了视交叉缺失。这些发现以前在 VACTERL 中没有报道过。
