Morning glory disk anomaly is a nonhereditary, congenital optic disk dysplasia characterized by conical excavation of the posterior fundus with a central glial tuft and radial retinal vessels. We report the case of a 4-year-old girl who presented with esotropia, enophthalmos, no light perception, and afferent pupillary defect in her left eye; fundus examination revealed morning glory disk anomaly. Ultrasound B-scan showed axial length increasing in the left eye on consensual light exposure. Magnetic resonance imaging/angiogram of the brain and orbits were within normal limits except for globe elongation posteriorly in the left eye. On examination under anesthesia with video indirect ophthalmoscopy, the left optic disk showed contraction and expansion when stimulated by strong light to the fellow eye and no spontaneous contraction on direct light stimulation. Morning glory disk contractility with increasing axial length on consensual light exposure in a child has not been reported previously.
牵牛花盘状异常是一种非遗传性先天性视盘发育异常，其特征为眼底后部呈圆锥形凹陷，伴有中央神经胶质束和放射状视网膜血管。我们报告了一名4岁女孩的病例，她左眼出现内斜视、眼球内陷、无光感和传入性瞳孔障碍；眼底检查发现牵牛花盘状异常。超声B超显示，在双眼受光照射时，左眼眼轴长度增加。除左眼后部眼球伸长外，脑部和眼眶的磁共振成像/血管造影均在正常范围内。在麻醉下进行视频间接检眼镜检查时，当强光刺激对侧眼时，左眼视盘出现收缩和扩张，而直接光刺激时无自发收缩。此前尚未报道过儿童在双眼受光照射时牵牛花盘状异常伴有眼轴长度增加及收缩性的情况。
