Peripalpebral folds and entropion in a male crab-eating macaque (Macaca fascicularis)

Multiple peripalpebral folds were the cause of severe bilateral blepharospasm and epiphora in a male Macaca fascicularis. The inner-most fold resulted in entropion and irritative keratitis. The condition was corrected surgically.

Congenital entropion in a litter of rabbits

Conjunctivitis and blepharospasm were observed in a litter of four, 2-week-old New Zealand white rabbits. Corneal opacity and neovascularization of the cornea and entropion of the upper eyelids were observed when the rabbits were examined 10 weeks later. Conjunctival cultures of these rabbits yielded normal bacterial flora. Treatment with a steroid-antibiotic ophthalmic ointment did not alter the ocular abnormalities. Surgical correction of the entropion resulted in a complete regression of all clinical signs.

[Entropion in newborn lambs. A simple method of treatment (author's transl)]

Entropion in newborn lambs apparently is hereditary and not due to blepharospasm, as it is believed to be in dogs in some cases. A simple method of treatment is described: a wound clip measuring 14 mm. is applied parallel to the margin of the affected eyelid.
