A rare ophthalmic disorder characterized by inflammation involving the vitreous and/or aqueous humors, usually due to bacterial or fungal infection. It may arise endogenously from hematogenous spread of the infectious agent, or exogenously after direct inoculation, and can take an acute or chronic course. Clinical signs and symptoms include progressive vitritis, hypopyon, reduced or blurred vision, red eye, pain, and lid swelling. The condition may be complicated by panophthalmitis, corneal infiltration and perforation, affection of orbital structures, and phthisis bulbi. [from
