(From, a goat, and

a face). See Aegidion. Aegylops or Aegilops. A disease in,the inward corner of the eye, (so called from a goat, and an eye, or goat's-eye,) because goats are supposed to be subject to this disease.

Paulus Aegineta calls it anchylops before it bursts, and agylops after; but these are only different states of the fistula lachrymalis. Dr. Wallis thinks that the distinction should be preserved. - See his Nosologia Methodica Oculorum. Article, Epiphora a Rhyade.

Sometimes it is with, and at others without, inflammation. If it is attended with erosion, it terminates, though seldom, in a cancer. In opening this abscess, we should be careful not to cut the edge of the eye-lid, for an incurable wateriness will be occasioned.

When it is strumous, it proceeds from congestion, and the tubercle is round without discolouring the skin. If- it is caused by inflammation, pain and redness appear over the eye. Sometimes it begins with a weeping, and is not suspected until a redness appears in the eye; and then, by a gentle pressure on the part, a matter is discharged, a part of which resembles the white of an egg. If this matter makes its way into the nose, it acquires a fetid smell.

As to the cure, if the case is recent, we should begin with a cautious use of bleeding and purging; or if these are contra-indicated, the alteratives most esteemed in scrofulous disorders should be used. The tumour may be resolved by anodyne and discutient applications; but if there is a tendency to a suppuration it should be hastened, and the discharge of the pus procured, with all convenient speed, lest the bone underneath should be affected: the abscess must be cleansed and healed, with the tinct. of myrrh and aloes mixed with mel rosae. If the matter had passed also under the cilium, a powerful desiccative, such as strong lime-water, assisted by a compress, should be used.

If the periosteum under the tumour be laid bare, an exfoliation must be hastened by a caustic, and a passage opened into the nose, after which dry lint alone is sufficient. Too constricting medicines may produce a rhyas, see Rhyas: too digestive applications may give rise to an encanthis. See Fistula lachrymalis.
