Overview
Uveitis is best described using various, concurrent classification systems. Uveitis 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, uveitis may be classified according to histological features of the inflammation such as granulomatous or non-granulomatous. Additionally, uveitis may be described by the laterality of the condition (unilateral or bilateral). Finally, uveitis may be classified by general underlying systemic causes such as infectious, autoimmune, drug-induced, or idiopathic.
Classification
Uveitis can be described according to the following classifications:[1][2]
- Classification by Anatomical Location
- Anterior uveitis: Iritis, cyclitis or iridocyclitis. Inflammation affecting, the iris, the ciliary body, or both.
- Intermediate uveitis: Viritis or pars planitis. Inflammation of the the vitreous humor or the pars plana.
- Posterior uveitis: Choroiditis, retinitis, or chorioretinitis. Inflammation of the choroid, the retina, or both.
- Panuveitis: Inflammation of the entire uvea.
- Classification by Duration of Symptoms[3]
- Acute: Active uveitis for less than 3 months.
- Chronic: Active uveitis for more than 3 months.
- Classification by type of inflammation[4]
- Granulomatous: showing granulomatous inflammation on slit lamp test
- Non-granulomatous showing no granulomatous inflammation on slit lamp test
- Classification by Laterality
- Unilateral: Single eye involvement
- Bilateral: Both eyes involvement
- Classification by Etiology[1][2]
- Idiopathic: No known cause
- Infectious: Bacterial, viral, fungal, or parasitic cause
- Autoimmune/Inflammatory: Caused by a systemic non-infectious inflammatory condition commonly associated with uveitis
- Drug-Induced: Iatrogenic cause by medications that are associated with incidence of uveitis
