Corneal ulcer in cats
Feline herpes virus infection is the most common cause of corneal ulcers in cats. The ulcer caused by the herpes virus is usually superficial and does not respond to antibiotic therapy.
If mistreated with topical and/or systemic steroids, these ulcers can worsen dramatically in a short period of time. Treatment of such ulcers is carried out using antiviral drugs. Deep ulcers on the cornea are most often associated with bacterial infection and require very intensive medical therapy.
If the corneal ulcer is deep, surgery is indicated to recover and heal the corneal tissue properly.
