Detailed Description

Patients with clinical diagnosis of chronic blepharitis were included in this study. A check list of symptoms and an ophthalmologic examination including best corrected visual acuity and biomicroscopy were performed.

Under a slit lamp visualization, three lashes with cylindrical dandruff of each eyelid were epilated by fine forceps. The lashes were immersed in fluorescein dye and examined under a light microscope at a 20-times magnification. The mites were detected based on its morphological characteristics and movement.

The patients with chronic blepharitis who had Demodex were randomly divided in two groups. The treatment group was prescribed lid hygiene with Tea Tree Oil shampoo 0.25% and ointment 5% daily and Tea Tree Oil oily solution 50% once a week - produced by Ophthalmos, São Paulo. The control group used the same posology of placebo similar products.

After six weeks, all subjects underwent the initial clinical and laboratory examination. The symptoms and the quantity of mites (mites/eye) were compared before and after the treatment in both groups.
