Computerized Tomography of Two Patients with Morning Glory Syndrome Okada, Koji Okada Koji Sakata, Hiroshi Sakata Hiroshi Shirane, Masako Shirane Masako Minamoto, Atsushi Minamoto Atsushi Choshi, Kanji Choshi Kanji open access Morning glory syndrome Cavum vergae Enlarged retrobulbar optic nerve Cerebral midline anomaly 490 Morning glory syndrome (MGS), an uncommon optic disc anomaly, is characterized by a funnel-shaped, excavated optic disc surrounded by chorioretinal pigmentary disturbance. Generally, it is an isolated ocular abnormality. The authors describe two patients in whom MGS developed in association with brain abnormalities. In both cases, there was enlargement of the optic nerve that showed increased radiodensity similar to that of sclera and cavum vergae in the brain cavity present in computerized tomography (CT). To our knowledge, the coexistence of MGS, cavum vergae and an enlarged retrobulbar optic nerve showing increased radiodensity have not been previously reported. The findings suggest that MGS may be based on a developmental anomaly involving the brain, and the enlarged optic nerve may be associated with sclera because of the isodensity in CT.
