[Demodicidosis in a female patient treated as allergic blepharoconjunctivitis. A case report].

A 65-year old woman suffered from therapy resistant chronic blepharoconjunctivitis and rosacea, without improvement under therapy of systemic and topic antibiotics and topic steroids and antihistamines. Demodex folliculorum was found adhered to the hair bulb on microscopic examination. She received oral ivermectin with good response. Two months later demodicidosis recurred. Then she was treated with a combination of ivermectin and transfer factor with total remission. Demodex folliculorum considered as saprophytic mite may play a pathogenic role in ocular diseases.
