Incidental isolated trichomegaly causing mechanical ptosis was noticed in a 7-year-old boy (left). The eyelashes measured 15 mm and were touching the lens of the spectacle (right). Hyperopia, left esotropia, and right optic disc pit were found on ocular examination. The child had normal stature, no learning difficulties, and no retinal pigmentary degeneration. Trichomegaly, or hypertrichosis of the eyelashes, is defined by increased length, thickness, stiffness, and curling of the eyelashes. It can be congenital or acquired. Congenital trichomegaly can be associated with pigmentary degeneration of the retina, dwarfism, and mental retardation (Oliver-McFarlane syndrome) or can be isolated. Trichomegaly is also one of the rare causes of mechanical ptosis. Thorough ocular and systemic examination is essential in patients with trichomegaly.
