Use of serology for diagnosis of infectious uveitis in cats

摘要

The uveal tract is composed of the iris, ciliary body, and choroid. The most common causes of exogenous uveitis include trauma, corneal ulceration, and penetrating wounds which usually can be diagnosed on clinical examination. Endogenous uveitis can be classified as parasitic, infectious, lens-induced, neoplastic, or idiopathic. Excluding lens-induced and neoplastic causes, there are no pathognomonic clinical ophthalmic changes associated with uveitis in the cat. Independent of etiology, aqueous flare, iritis, keratic precipitates, hyphema, and hypopyon commonly develop in the anterior chamber. The choroid can be inflamed with or without concurrent anterior segment involvement. Appropriate management of uveitis in the cat is important to avoid lens luxations, cataract formation, and glaucoma, 3 common sequelae to intraocular inflammation.
