Congenital Distichiasis in a Young Male: A Rare Case without Systemic Association.

Congenital distichiasis is a rare eyelid disorder typically associated with lymphedema-distichiasis syndrome. However, isolated forms without systemic manifestations have also been recognized. This report presents a 28-year-old male with long-standing bilateral eye rubbing and recent unilateral visual blurring. Slit-lamp examination revealed distichiasis arising from meibomian gland orifices, more prominent in the left eye, without corneal involvement. A diagnosis of isolated congenital distichiasis was made. The patient underwent selective electroepilation with complete symptom relief and no recurrence at 3 months. This case underscores the phenotypic variability of congenital distichiasis and highlights the effectiveness of electroepilation as a safe, noninvasive first-line intervention in isolated cases.
