An unusual case of eye itchiness.

FIG 3. Electronic microscopy of a louse grasping a lash FIG 4. Electronic microscopy of a nit cemented on a lash and is often neglected because of its semitransparent body and deep burrowing in the lid margin.2 Other ocular signs and symptoms include eye itchiness and grittiness, blepharitis, follicular conjunctivitis, and marginal keratitis. The adult female lice lay three eggs per day and 26 eggs per lifetime which hatch every 7 to 10 days. The nits are laid and cemented on the hairs, have a darkish colour, and their cap or operculum is conical (Fig 4). The average lifespan of adult lice is less than a month, and they die within 24 to 48 hours if removed from their hosts. Crowded conditions and poor personal hygiene are risk factors for infestation.1
