Iris heterochromia and unilateral eyelash hypertrichosis.

An 87-year-old female with a history of open-angle glaucoma presented with longer, thicker eyelashes on the right side compared to the left. Her irides were also different colors, as the right iris was brown and the left was hazel (green-brown). The patient had noticed a gradual darkening of her right iris and lengthening of her eyelashes over the last year, but denied visual changes or foreign-body sensation. Past medical history included a remote history of breast cancer treated by lumpectomy and radiation therapy, cerebrovascular accident, hypercholesterolemia, and hypertension. Her medications included bimatoprost, atenolol, atorvastatin, and clopidogrel.
