Eye Test

Question
A 3yo neutered female domestic shorthair cat is presented for evaluation of a left ocular abnormality (see Figure). The cat is a confirmed FHV-1 carrier but is otherwise healthy. The owner reports that the eye condition was first noticed around 3 weeks previously and that it has gradually progressed since that time. No signs of ocular discomfort have been noted and the other eye is unaffected.
What is the most likely diagnosis in this case?
How could the diagnosis be confirmed?




















Answer
The clinical appearance is characteristic of eosinophilic keratitis.
Diagnosis can be confirmed by corneal cytology, which should show a mixed inflammatory response including eosinophils.
