Trichiasis refers to a condition where the eyelashes grow inward toward the eyeball, a sign related to the eye. Common symptoms include a foreign body sensation in the eye, photophobia, tearing, and even eye pain. Generally, an ophthalmologist can confirm the diagnosis with an examination under a slit lamp microscope. Therefore, it is not necessary to perform a fundus examination for trichiasis; a diagnosis can be clearly established just by using a slit lamp microscope examination.
