The spontaneous development of entropion in a laboratory cat
Peneyra, Samantha M.
An 11-month old, intact male domestic short-haired cat presented to the Cornell University Center for Animal Resources and Education (CARE) laboratory animal veterinarians on January 18, 2013 for complaints by the animal husbandry staff of severe squinting in the left eye. Upon presentation, physical examination abnormalities noted with the patient included blepharospasm in the left eye and excoriations over the left temple region. Fluorescein staining of the left eye revealed a superficial corneal ulcer along the lateral cornea near the limbus. At that time, it was presumed that the patient acquired the corneal ulcer secondary to trauma. Initial therapy and treatments included a triple antibiotic ointment in the left eye three times a day, atropine ointment in the left eye twice a day, a non-steroidal anti-inflammatory drug injection subcutaneously once a day, daily monitoring, and an Elizabethan collar. When the corneal ulcer did not resolve and examination of the left eye on January 25, 2013 revealed additional clinical signs such as photophobia, a mucopurulent discharge, and a prolapsed third eyelid, an ophthalmology consult through the Cornell University Hospital for Animals was sought. The ophthalmologist diagnosed our patient with a lower lid entropion of the lateral canthus. The etiopathogenesis of the entropion was initially thought to be primary in origin; however, further evaluation of the left eye with an anesthetic agent revealed a secondary entropion. Over time, another ophthalmology consult was sought when a second corneal ulcer appeared in the left eye. The consult revealed a marked entropion that was not resolving and, consequently, recommended surgical intervention. Prior to surgery, an anesthetic agent was applied to the left eye and this time, the entropion did not resolve or decrease. The patient was taken to surgery on February 20, 2013 and a Hotz-Celsus technique was performed on the left eye to correct the entropion. As soon as the corneal ulcer began healing on the left eye, the cat re-presented to the CARE laboratory animal veterinarians on March 7, 2013 for complaints of severe squinting, conjunctivitis, discharge, and inward rolling of the lower lid on the right eye. A second surgery was performed using the Hotz-Celsus technique to correct the entropion on the contralateral side.
