Uveitis is inflammation inside the eye. [1] Onset is usually sudden. [1] Early symptoms include blurry vision, floaters, eye pain, red eye, and sensitivity to light. [1] One or both eyes may be affected. [1] Complications may include loss of vision and glaucoma. [1] [2]
Causes may be unknown, eye infection, or autoimmune conditions. [1] [4] Risk factors include cigarette smoking. [1] The uvea is the iris, ciliary body, and choroid. [1] It is divided into anterior, intermediate, and posterior uveitis; though in panuveitis all parts may be affected. [1] Diagnosis is based on symptoms and a dilated eye exam. [1]
Treatment is usually with steroids, most commonly as eye drops such as prednisolone. [1] [5] In severe cases steroids by mouth or by injection may be used. [5] If steroids are not effective other immunosuppressants such as methotrexate may be used. [5] Cycloplegics, such as atropine, may be used to help with pain and prevent complications. [3] In cases due to infection, specific treatment for the infection is also required. [2]
Uveitis affects about 1 in 3,000 people per year. [4] It most commonly occurs in those between the ages of 20–60; though any age may be affected. [1] Males and females are affected at similar rates. [4] It accounts for about 5-10% of vision problems globally and is the cause of up to 25% of blindness in the developing world. [4] With appropriate treatment outcomes are usually good. [3]
