Lid margin abnormalities – Trichiasis

Trichiasis is a condition in which there is misdirection of eyelashes. If the eyelashes turn in toward the eyeball and scratch the cornea, they produce a sensation like a foreign body. This condition may result from trachoma (an eye infection), burns or injuries to the lids. Removal of the offending lashes or corrective plastic surgery on the lid relieves the symptoms.
