distichiasis

Congenital anomaly in which there is a double row of eyelashes in the lid margin, one row being normal and the other row turning inward towards the eye. Distichiasis can also be acquired following scarring or chemical and physical injury. If there are symptoms, treatment consists of removal of the aberrant eyelashes, usually by cryotherapy (removal under cold or freezing conditions) or electrolysis. See epilation; polystichia; trichiasis.
