ENDOGENOUS UVEITIS ETIOPATHOGENY
Abstract:
Uveitis represents the inflammation of the structures that make up the uveal tract: the iris, the ciliary body and the choroid, or of the adjacent ocular structures (the retina, the optic nerve, the vitreous, the sclera). The etiology is attributed, in most cases, to the autoimmune mechanisms. In terms of the location of the pathological processes, uvea can be divided into two portions: the anterior portion, irrigated by the ciliary arteries and the long posterior ciliary arteries; the posterior portion, irrigated by the posterior short ciliary arteries. The vascular arrangement explains the limitation of some inflammatory processes to one of the two territories. The existence of two vascular territories, one anterior (iridociliary) and one posterior (choroidal) explains the possibility of limited inflammation occurrence, either in the first territory or in the posterior one. Still, there are cases when both territories can be covered by an inflammation, either simultaneously or successively.
