morning glory anomaly

morn·ing glo·ry a·nom·a·ly

A rare, usually unilateral dysplastic coloboma, characterised by mottled peripapillary pigment and an enlarged, funnel-shaped optic disc filled with hyaloid remnants in its base, surrounded by an elevated rim and tortuous radiating vessels—hence the name, likened to the appearance of the morning glory, a flower; it is thought to occur during the 5th week of embryonic development
