Intermediate uveitis is a medical condition that affects the middle layer of the eye. It is also known as pars planitis. There are several synonyms for intermediate uveitis that can be used interchangeably. Some of these synonyms include chronic cyclitis, vitritis, periphlebitis, and posterior uveitis. The condition is marked by inflammation in the vitreous or the jelly-like substance present in the middle of the eye. Intermediate uveitis can cause symptoms such as blurry vision, floaters, and eye pain. It is commonly associated with autoimmune diseases such as multiple sclerosis or sarcoidosis. Early diagnosis and treatment of intermediate uveitis are crucial to prevent serious complications such as retinal detachment or glaucoma.
