The purpose of this study was to evaluate the efficacy of topical ivermectin 1% cream application on the eyelashes in combination with eyelid hygiene in the treatment of Demodex blepharitis.

102 eyes of 102 patients with symptomatic Demodex blepharitis were divided into 2 groups according to the use of topical ivermectin in this retrospective case–control study. The ivermectin group (n = 51) applied topical ivermectin 1% cream on the eyelashes for 15 minutes once weekly, but the control group (n = 51) did not. In both groups, eyelid hygiene was performed once daily. The Standard Patient Evaluation of Eye Dryness (SPEED) symptom questionnaire score, Oxford staining score, eyelid debris, eyelid redness/swelling, and telangiectasia were assessed during the follow-up visits.

Results:
--The mean follow-up periods of the ivermectin and control groups were 15.1 ± 9.7 weeks and 14.8 ± 8.6 weeks, respectively.

--The SPEED score and eyelid debris grade were significantly improved in both groups during the follow-up, although the SPEED score and eyelid debris grade showed greater changes in the ivermectin group than in the control group.

--The Oxford staining score, eyelid redness/swelling grade, and telangiectasia grade were significantly improved only in the ivermectin group but not in the control group.

In addition to eyelid cleanliness, the application of topical 1% ivermectin cream for 15 minutes once a week has improved considerably, in addition to eyelid hygiene, eyelid surface coloring, eyelid debris, redness, and telangiectasia, in patients with Demodex blepharitis in comparison to eyelid hygiene only. These data suggests the effective treatment of Demodex blepharitis by topical ivermectin 1 percent cream administration.
