Optic disk contractility in morning glory disk anomaly.

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.
