A 59-year-old woman with an 8-year history of open-angle glaucoma treatment was referred for continuation of care. At her initial evaluation, she was treated with bimatoprost, 0.03%, and timolol, 0.5%, in each eye. Her intraocular pressures were 13 mm Hg in the right eye and 14 mm Hg in the left eye. Cup to disc ratios were 0.7 and 0.8 in the right and left eyes, respectively. The remaining ocular examination and medical history were remarkable for seasonal allergies. Given ocular sensitivity to these medications, her therapy was continued with preservative-free timolol and latanoprost, which was subsequently changed to travoprost (Travatan Z; Alcon Inc, Hünenberg, Switzerland), with a dose of 1 drop daily at bedtime in each eye. Two years later, she was diagnosed as having breast cancer and was treated with 4 cycles of intravenous doxorubicin hydrochloride (Adriamycin; Pharmacia & Upjohn, New York, New York) and cyclophosphamide (Cytoxan; Bristol-Myers Squibb Company, Princeton, New Jersey). Approximately 4 weeks after completing chemotherapy, she had complete scalp hair loss and partial eyebrow hair loss but retained her eyelashes (photographs could not be obtained at that time owing to adverse effects of chemotherapy). She subsequently received localized radiation treatment to the breast area for 7 weeks without additional reported hair loss. One week after completing radiation treatment, her scalp and eyebrow hair were in a regrowth stage and her eyelash appearance was unchanged (Figure).
