ABSTRACT

The uvea is the vascular tunic of the eye and the anterior uvea consists of the iris and ciliary body. The anterior uvea is the most common origin of primary intraocular tumors in all species of domestic animals. Anterior uveitis with toxoplasmosis and systemic mycoses may have organisms readily demonstrable in the posterior uvea/subretinal space, but organisms are rarely present in the anterior uvea. The ocular inflammation is usually confined to the anterior uvea, cornea, and lids but may cause endophthalmitis. The eye may contain one or more cysts, which, in the dog, are often free floating in the anterior chamber. The anterior chamber is the space demarcated posteriorly by the lens and the iris and anteriorly by the cornea and the iridocorneal angle. The posterior chamber is delineated anteriorly by the posterior surface of the iris, peripherally by the ciliary body, and posteriorly by the anterior vitreous face/hyaloid membrane.
