EGILOPS, the name of a tumor in the great angle of the eye; either with, or without, an inflammation. The word is compounded of o, goat, and eye; as goats are supposed extremely liable to this distemper.
Authors frequently use the words egileops, anchileops, and fistula lachrymalis, promiscuously; but the more accurate, after Egineta, make a difference.—The tumor, before it becomes ulcerous, is properly called anchileops; and, after it is got into the lachrymal passages, and has rendered the os lachrymale carious, fistula lachrymalis.
If the egileops be accompanied with an inflammation, it is supposed to take its rise from the abundance of blood which a plethoric habit discharges on the corner of the eye. If it be without an inflammation, it is supposed to proceed from a viscous pituitous humour, thrown upon this part.
The method of cure is the same as that of the ophthalmia. But before it has reached the lachrymal passages, it is managed like other ulcers. If the egileops be neglected, it bursts, and degenerates into a fistula, which eats into the bone.
