Uveitis is characterized by inflammation of the uvea—the middle portion of the eye composed of the iris, ciliary body, and choroid—causing eye redness, pain, photophobia, floaters, and blurred vision. Adults aged 20 to 50 years are primarily affected by uveitis, and untreated uveitis may cause cataracts, glaucoma, macular edema, retinal detachment, optic nerve damage, and vision loss. ➡️ Learn more about the epidemiology, pathophysiology, diagnosis, and treatment of uveitis in adults in this JAMA Review: ja.ma/43DgrIe
