Morning Glory Optic Nerve Anomaly
The condition is usually unilateral.
Morning glory optic nerve anomaly. Morning glory syndrome mgs is an optic neuropathy characterized by a congenital funnel shaped excavation of the posterior fundus that incorporates the optic disc malformation resembling the morning glory flower mgs is usually unilateral and may result in a decrease. Thus the morning glory disc is sometimes misdiagnosed as an optic nerve coloboma. Morning glory disc anomaly is a congenital malformation of the optic nerve characterized by an enlarged optic disk opening and excavation of the peripapillary fundus with outward radiating papillary vessels the appearance of which resembles the morning glory flower. Morning glory disc anomaly mgda is a congenital optic nerve anomaly characterized by a funnel shaped excavation of the posterior globe that incorporates the optic disc.
It is important to differentiate from a morning glory disc anomaly because optic nerve colobomas can be associated with systemic syndromes such as charge coloboma of the eye heart defects choanal atresia growth. The etiology of morning glory disc anomaly is poorly understood. It is also called morning glory anomaly. Morning glory disc anomaly is rare and is more commonly found in females 2.
Optic nerve colobomas also lack the central glial tuft and peripapillary pigmentation seen in morning glory disc anomalies. Patients may be initially referred for leukocoria or strabismus and present with variable visual acuity which depends on the extent of the optic nerve anomaly. Morning glory disc anomaly 62 64. 1 the term was first coined in 1970 by kindler 2 who noted the resemblance of the malformed optic nerve to the morning glory flower.
Morning glory syndrome definition. The funduscopic appearance of the mgda includes 3 primary features. The morning glory disc anomaly mgda is a congenital deformity resulting from failure of the optic nerve to completely form in utero. Retinal vessels emanate radially beyond a central white core and the disc itself is encircled by an elevated region of chorioretinal pigmentation.
An enlarged funnel. Morning glory disc anomaly mgda is typically a unilateral congenital disorder characterized by the funnel shaped excavation of an enlarged optic disc.
