A symptom observed isconstant irritation, which is caused by the hair of the lashes beingdirected toward the cornea. We also see a marked increase in lachrymalsecretion, a twitching and convulsive compressing of the eyelids, and athick, gray, purulent mucus accumulates in the corners of the hairs of the eyelashes become adherent, and the eyelids may becomecompletely glued together. Besides this we see an intense inflammatorycondition of the connective tissue, and in some cases inflammation of thecornea, and in extremely bad cases ulceration (ulcerative keratitis).

We may expect a relapsein such cases where we do not entirely remove the conjunctivitis (primaryor secondary) at the same time as the entropion. Therapeutics.—It is only in fresh and very mild forms of the diseasethat we may expect to obtain any favorable results by means of medicinaltreatment, and this must be directed toward removing the conjunctivitiswhich exists in conjunction with entropion, otherwise an operation alonewill answer. The following methods of operation are suggested:The best method is to carefully remove the hair and thoroughlydisinfect the surrounding tissue, and a fold of tissue running parallel tothe edge of the lid is picked up by means of a pair of entropion or ordi-nary artery forceps, the fold of skin lifted ]:)eing sufficiently large tomake the lid lie
