Figure 4.

Migration of Demodex by lid scrub with TTO. In this eye with diffuse CD found in the lashes before treatment (a), lash to be epilated (marked by arrow) showed a fragment of CD attached to the lash and abundant Demodex embedded close to the lash follicle (d). After lid scrub in the orifice with 50% TTO, the lashes became clean and totally free of CD, but tails of Demodex were protruding from the lash roots (b, arrow). At 3 minutes after lid scrub, free Demodex was found on the trunk close to the skin surface, i.e. away from the lash follicle in the epilated lash (e). Rotating these lashes (shown in b) before epilation allowed us to detect a group of Demodex migrating along the lash trunk (f and g). If no lid scrub was carried out at home for one week, CD returned to the lashes 1 week later (c). With permission from Br. J. Ophthalmol.⁸
