The morning glory anomaly is a rare congenital clinical entity that results from abnormal optic nerve development. In our series of 30 patients, followed for a mean duration of 10.3 years, 11 developed associated retinal detachments. These detachments followed a variable clinical course, including spontaneous reattachment and even redetachment, and may result from an abnormal communication between the subarachnoid space of the optic nerve and the subretinal space, allowing cerebrospinal fluid to accumulate subretinally. The clinical findings (including ultrasonography, computed tomography, and electrophysiologic testing), natural history, complications, and therapeutic indications are discussed.
