A rare, non-hereditary congenital defect of the optic nerve head where the nerve appears dramatically enlarged and funnel-shaped, often containing a central glial tuft (tissue clump), resembling the flower of a morning glory.
read more about morning glory disc anomaly ...Vision in the affected eye is often significantly reduced, ranging from counting fingers to only light perception, and is frequently associated with an amblyopic (lazy) eye.
The condition is often associated with other defects, including basal encephalocele (a brain hernia) and structural abnormalities of the cerebral arteries.
Diagnosed during a fundus examination where the optic nerve head is observed to be enlarged, excavated, and surrounded by a rim of chorioretinal pigmentation.
It is almost always unilateral (affects only one eye), which helps distinguish it from similar bilateral optic nerve anomalies.
Unfortunately, because the anomaly involves the underlying structure of the nerve, the resulting vision loss is permanent and cannot be fully corrected with glasses or surgery.
Serous retinal detachment can occur, where fluid accumulates under the retina due to communication between the retinal space and the cerebrospinal fluid space near the disc.
