Morning Glory Syndrome: An Unusual Optic Disc Anomaly
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 4
Abstract
The morning glory disc anomaly is congenital excavation of posterior pole that involves the optic disc. The term reflects the morphological similarity to the flower, the morning glory plant. It is a sporadic condition usually unilateral, though bilateral lesions have been reported. Morning glory discs are more common in females (2:1). The pathogenesis of the condition is unknown. One hypothesis argues that the condition results from failure of closure of the fetal fissure and that it is a variant of optic nerve coloboma. Alternatively, a primary mesenchymal abnormality has been postulated on the basis of the glial tuft, the scleral and vascular abnormalities .It is characterized by funnel-shaped and enlarged dysplastic optic disc with white glial tissue, and retinal vessels arising from the periphery of the disc (spoke wheel pattern) and running an abnormally straight course over the peripapillary retina. Patient can present with visual acuity 6/6 to hand movement. It can cause amblyopia, strabismus even retinal detachment. No definitive treatment is present till date. MGS patients are kept on routine follow up to prevent and treat complications.
