Differential Diagnosis of Noninfectious Retinitis

Abstract

Retinitis is a posterior uveitis that affects mainly the retina. Retinitis lesions can be focal, multifocal, or disseminated (diffuse). Size and location (periphery/posterior pole/macula) are important. It is also essential to identify if the disease is restricted to the eye or if it is a part of serious underlying systemic disease (collagen vascular autoimmune disease, systemic infection, etc.).
