A Rare Case of Unilateral Morning Glory Disc Anomaly in a Patient with Turner Syndrome: Report and Review of Posterior Segment Associations

Abstract EN

Turner syndrome is a common sex chromosome disorder affecting females.

The disorder is caused by a partial loss, complete absence, or structural abnormality of one X chromosome.

The clinical presentation is broad and ranges from the classic phenotype to minimal clinical manifestations.

Ocular abnormalities associated with the syndrome are common.

Reports describing abnormal eye features in individuals with Turner syndrome generally involve refractive errors (myopia or hyperopia), strabismus, and external or anterior segment abnormalities including hypertelorism, epicanthal folds, and ptosis.

Posterior ocular segment anomalies involving the optic nerve and retina in Turner syndrome have been rarely reported.

We report a rare presentation of an 11-year-old female with Turner syndrome and unilateral morning glory disc anomaly.
