eyelids (40×, 100×) was negative. The condition disappeared and the patient remained stable during the past 6 months. Treatment of blepharitis associated to Demodex must target the elimination thereof by daily palpebral cleaning (sterile towels, soaps) as well as local lubricants. Cleaning crusty formations from palpebral edges utilizing topical ether has been applied with excellent results.3 Recently, oral ivermectin has been postulated as a new treatment for resistant chronic blepharitis due to infestation by the said parasite. As described by Nogueira et al.2 the use of this drug seems to be an efficient and safe alternative in addition to its advantages such as ease of posology and absence of adverse effects. However, the use of this drug in our patient did not diminish the number of parasites or improve the symptoms. In conclusion, the application of cotton swabs dipped in ether associated to conventional topical measures is a safe method and provides good results in short periods of time. It constitutes a classical, efficient and economic alternative for patients with chronic blepharitis associated with infestation by Demodex resistant to treatment with oral ivermectin.
