Morning glory disk anomaly: a computerized analysis of contractile movements with implications for pathogenesis.

ABSTRACT

Excavated optic disk anomalies, such as morning glory disk anomaly, peripapillary staphyloma, and optic disk coloboma, are rare. Contractile movement of a given lesion is even rarer. Only 4 patients with morning glory disk anomalies accompanied by contractile movement have been reported. We offer a computerized analysis of the contraction, observable on a video recording of a patient with this disorder, with an explanation of the possible pathogenesis of the disorder.
