Anterior uveitis

A report in AJVR (60:932-936,1999) indicates that some cats with chronic anterior uveitis have FHV-1 antigen in aqueous humor as well as intraocular production of antibody against FHV-1. These results may indicate that some previously diagnosed "idiopathic uveitis" cases may have FHV-1 as an underlying cause. Systemic therapy with antivirals and judicious use of topical steroids may be useful in treating these previously frustrating cases.

Recurrent erosions (AKA "Indolent ulcers")

Most veterinary ophthalmologists believe that all "superficial erosion complex" cases in cats are a form of FHV-1 infection and not necessarily a degenerative disease of the cornea that often accompanies middle age and specific breeds as in the canine. Some ophthalmologists treat these with topical anti-virals and antibiotics, following gentle cotton swab debridement and/or treatments with dilute betadine. Topical bandage contact lenses or topical nalbuphine may also help improve patient comfort without delaying healing. A study in cats demonstrated that linear grid keratotomies in cats increased the rate of development of sequestra, and is therefore contraindicated.
