Congenital Entropion in Lambs

Entropion is a medical condition in which the eyelid (usually lower) folds inward. It causes irritation and abrasion of the cornea. Entropion occurs in all breeds of sheep and goats. It is transmitted genetically and may also have environmental influences.

Belgian scientists recently investigated congenital (present from birth) entropion in a flock of purebred and crossbred Texel and Ile de France sheep. Fifty-two lambs were affected. They were monitored from birth until a complete recovery occurred. Ocular examinations were performed and clinical signs were scored.

Gender had no effect on the occurrence of entropion, but triplet, crossbred, and Ile de France lambs had a higher incidence. The median time after which eyes with entropion recovered spontaneously was 7 days (range 2–42 days). No significant differences were found between groups regarding average daily gain.

The researchers concluded that the occurrence of entropion was affected by litter size and breed, but that the condition did not affect growth and resolved spontaneously.

A 2 week old Boer kid that I'm treating for entropion in both lower eye lids. I've been using my "sterilized" fingers to gently pull down the lower lids to make the inverted eyelid flex outward and stretch the skin. (This has worked in other cases) One lid is almost 100% normal; the other is more problematic. I saw a post elsewhere where it was suggested to inject 1-2 ml of long-lasting penicillin into the affected lower eye lid to swell it and make the inverted eyelid flex outward.
