Congenital horizontal tarsal kink.
A 3-week-old male infant had an extreme form of entropion caused by a congenital horizontal tarsal kink, which led to corneal ulceration and visual impairment. The combination of absence of the upper eyelid fold, irritability, and blepharospasm in the absence of congenital blepharoptosis is a sign that may facilitate early recognition of this problem.
