WHAT IS OCULAR INFLAMMATORY DISEASE?
Ocular inflammatory disease (OID) is a general term for inflammation affecting any part of the eye or surrounding tissue. Inflammation involving the eye can range from the familiar allergic conjunctivitis of hay fever to rare, potentially blinding conditions such as uveitis, scleritis, episcleritis, optic neuritis, keratitis, orbital pseudotumor, retinal vasculitis, and chronic conjunctivitis. Broadly speaking, if inflammation develops in the eye(s), or in the optic nerve, blood vessels, muscles or other tissues that surround the eye, the resulting illness is classified as an ocular inflammatory disease (or OID for short). The location of the inflammation governs the diagnostic name for the ocular inflammatory disease. For example, uveitis is inflammation in the uveal tract; scleritis is inflammation of the sclera, pars planitis is inflammation of the pars plana, and so forth.
