The most widely used classification of uveitis is the one devised by the International Uveitis Study Group (IUSG) in 1987, based on the anatomical location of the inflammation. This classification includes anterior uveitis (iritis, iridocyclitis, and anterior cyclitis), intermediate uveitis (para planitis, posterior cyclitis, and hyalitis), and posterior uveitis (focal, multifocal, or diffuse choroiditis, chorioretinitis, retinitis, and neuroretinitis). An additional term, panuveitis (anterior chamber, vitreous, retina, and choroid), is also described.
Anterior uveitis comprises inflammation, primarily affecting the anterior segment. Anterior uveitis is the most common form of intraocular inflammation. In a general or comprehensive ophthalmology practice, most patients presenting do not have an underlying systemic disease; instead, 50% of patients presenting with inflammation have predominantly anterior disease caused by either trauma or, most commonly, an idiopathic postviral syndrome.
