Secondary keratitis or uveitis may occur with scleritis. DR1-DQ5 is associate with tubulointerstitial nephritis & uveitis syndrome. Hyphema, anterior uveitis and glaucoma are three main pathologies in this area. This can cause glaucoma, uveitis, or damage to the cornea. It is known to lead to uveitis, glaucoma, and retinal detachment. Poorly controlled chronic anterior uveitis may result in permanent eye damage, including blindness. Patients with episcleritis experience far less photophobia than patients with uveitis. Rheumatoid arthritis is not uncommon in Asian countries as a significant association of uveitis. Steroid eye drops are usually the first line treatment for anterior uveitis. Preexisting eye disorders such as uveitis are another contraindication. It can also occur after injuries to the eye or inflammation in the eye (uveitis). The most common form of uveitis is acute anterior uveitis (AAU). Eye drops are also available which are used to treat uveitis and early amblyopia. Typically, there is no uveitis, or thickening of the sclera. Bacterial infection is another significant contributing factor in developing uveitis.
