Trichiasis is a condition of abnormal eyelash growth with misdirection posteriorly. Distichiasis is an abnormality of a second row of lashes emanating from meibomian glands. In both conditions the lid margin is in a normal position. Involutional entropion is an eyelid malposition with secondary trichiasis. These conditions can cause significant keratopathy. This chapter explores treatment modalities.
