#ophtalmology #eyes #surgery #oftalmología #ojos #cirugía Uveitis is an inflammation of the uvea, which is the middle layer of the eye wall. The uvea contains many blood vessels and provides nourishment to the eye. It consists of three parts: Iris: The colored part of the eye. Ciliary body: Produces the fluid inside the eye (aqueous humor) and helps with focusing. Choroid: The vascular layer between the retina and the sclera. Uveitis can affect any part of the uvea and is classified based on the location of inflammation: Anterior uveitis (iritis): Affects the front part of the eye, including the iris and ciliary body. It is the most common type. Intermediate uveitis (pars planitis): Affects the middle part of the eye, the vitreous humor and the area behind the ciliary body (pars plana). Posterior uveitis (choroiditis or retinitis): Affects the back part of the eye, involving the choroid and/or the retina. Panuveitis: Occurs when all layers of the uvea are inflamed. Symptoms of Uveitis: Symptoms can develop suddenly and worsen quickly, although in some cases they develop gradually. They can affect one or both eyes and may include: Eye redness Eye pain (can range from a mild ache to intense discomfort, may worsen when reading) Light sensitivity (photophobia) Blurred vision Dark, floating spots in your field of vision (floaters) Decreased vision Small or distorted pupil Sometimes, uveitis may not cause any noticeable symptoms, and signs might only be detected during a routine eye exam. Causes of Uveitis: The cause of uveitis is not always clear. However, it can be associated with: Autoimmune diseases: Such as ankylosing spondylitis, rheumatoid arthritis, lupus, inflammatory bowel disease (Crohn's disease, ulcerative colitis), and Behcet's disease. Infections: Including herpes simplex, herpes zoster (shingles), syphilis, toxoplasmosis, Lyme disease, and cytomegalovirus (CMV). Eye injury. Exposure to toxins. Rarely, certain types of cancer (neoplasia) within the eye. In many cases, the exact cause of uveitis cannot be identified. Treatment of Uveitis: The primary goals of uveitis treatment are to reduce inflammation, relieve pain, and prevent vision loss and complications. Treatment depends on the type and severity of uveitis and may include: Corticosteroids: These are the mainstay of treatment to reduce inflammation and can be administered as eye drops (for anterior uveitis), injections around or into the eye, or oral or intravenous medications (for more severe or posterior uveitis). Pupil-dilating eye drops (mydriatics and cycloplegics): These help to reduce pain associated with iris spasms and can prevent the iris from sticking to the lens. Antibiotics, antivirals, or antifungals: Prescribed if the uveitis is caused by an infection. Immunosuppressive drugs: May be necessary for severe uveitis that doesn't respond to corticosteroids, affects both eyes, or is associated with an autoimmune disease. Examples include methotrexate, azathioprine, cyclosporine, and biologics. Medication-releasing implants: For difficult-to-treat posterior uveitis, a device that slowly releases corticosteroids into the eye over a prolonged period may be implanted. Surgery: Rarely needed but may be considered to treat complications like cataracts or glaucoma. Early diagnosis and treatment are crucial to prevent potential complications of uveitis, which can include: Glaucoma Cataracts Retinal swelling (macular edema) Retinal scarring Retinal detachment Optic nerve damage Permanent vision loss
