Make the Diagnosis: Fall 2019

A 10-month-old female infant underwent neuro-ophthalmic evaluation for a new-onset lid ptosis and pupillary miosis on the right side. There was no history of birth trauma. Vision, eye movements, fundi, and general examination were normal.

Have you figured out this diagnosis? The correct answer is Horner syndrome, the topic of the Winter 2020 issue’s lead story.

The answer to last issue’s quiz is Graves disease, the topic of this issue’s lead story. Congratulations to Todd Sterner, MD, of Jenkintown, Pennsylvania, who submitted the first correct answer.
