An 87-year-old woman with a history of open-angle glaucoma in her right eye presented with longer, thicker eyelashes on the right side compared with the left. Her irises were also different colors: the right iris was brown, and the left was hazel (green-brown) (Figure 1). The patient had noticed a gradual darkening of her right iris and lengthening of her eyelashes during the last year but denied visual changes or foreign-body sensation. Her medical history included a cerebrovascular accident, hypercholesterolemia, and hypertension and a remote history of breast cancer treated with lumpectomy and radiation therapy. Her medications included bimatoprost, atenolol, atorvastatin, and clopidogrel.
