Abstract The uvea comprises the middle coat of the eye and consists of the iris, ciliary body, and the choroid. Uveitis is a group of disorders that involves inflammation of the layers of the uvea.(1) Anterior uveitis is is the most common form of ocular inflammation, often causing a painful red eye. Anterior uveitis is distinguished from the other causes of a red eye by slit lamp examination. Iritis is appreciated by detection of leukocytes in the anterior chamber with the slit lamp. Additionally, a haze, described as ”flare,” may also be appreciated which reflects protein accumulation in the aqueous humor due to disruption of the blood-aqueous barrier.(2) In anterior uveitis, the primary site of inflammation is the anterior chamber. Occasionally, cystoid macular edema may be observed (especially in HLA-B27- associated disease); however, this is a more common feature in intermediate, posterior, or pan-uveitis (3). Most clinicians do not perform optical coherence tomography (OCT) evaluation in case of patients who exhibit normal retinal morphology upon slit-lamp bio-microscopy. For these reasons, choroidal and retinal changes in active anterior uveitis are not well known. |
