Treatment.—Raise the fold and dissect it away from all points of attachment.
TRICHIASIS (INVERSION OF THE EYELASHES).
In the simplest form the eyelashes bend inwardly, touching the eyeball, causing irritation and simple conjunctivitis. It may be also associated with entropion.
Treatment.—The offending eyelashes should be cut off or pulled out. In case the natural growth of the eyelashes is directed inward, an operation similar to that for entropion becomes necessary.
ENTROPION (INVERSION OF THE EYELID).
In inversion of the eyelid the eyelashes soon irritate the anterior face of the cornea and produce more or less inflammation and opacity. The inversion may be due to the growth of a tumor within or without the lid, to abscess, laceration, or injury, causing the lid to lose its natural conformity to the eyeball, ulcerations, etc. Surgical interference in either case becomes necessary to restore the lid to its natural direction.
ECTROPION (EVERSION OF THE EYELID).
This serves to injure the eye by permitting dust or other foreign substances to enter the eye and interferes with the natural removal of them.
Treatment.—A delicate surgical operation—the removal of an elliptic section of the palpæbral conjunctiva—may remedy the defect.
