Ocular Manifestations of Long-Term Mascara Use

Abstract

Mascara, a widely used cosmetic, is associated with eye pathology. The authors report 3 cases of eye problems secondary to long-term mascara use. Two patients had multiple pigmented conjunctival lesions; one of these had a history of melanoma of the hand. Conjunctival biopsy revealed nonmelanocytic pigment granules within conjunctival stroma cells in both cases. The other patient had a history of dry eye, and also showed pigment clumping around a punctal plug. The third patient had canalicular obstruction from a mascara-laden dacryolith ("dacryomascaralith"), the first such case reported. A literature review revealed cases of eyelid dermatitis, infectious keratitis, a conjunctival mass ("mascaroma"), and others. Ophthalmologists should be aware of mascara's associated eye problems. The physical findings combined with a high index of suspicion, especially in cases of heavy mascara use, may allow for an accurate diagnosis and spare the patient an otherwise unnecessary invasive procedure.
