<unk>  is best described using various, concurrent classification systems.<unk>  may be classified according to anatomical location into 4 subtypes, depending on which part of the uvea is primarily affected: anterior, intermediate, posterior, and panuveitis. Based on the duration of symptoms it may be further sub-classified as acute or chronic. Upon further investigation,<unk>  may be classified according to histological features of the inflammation such as granulomatous or non-granulomatous. Additionally,<unk>  may be described by the laterality of the condition (unilateral or bilateral). Finally,<unk>  may be classified by general underlying systemic causes such as infectious, autoimmune, drug-induced, or idiopathic.
