Retinitis(redirected from actinic retinitis)
Also found in: Dictionary, Thesaurus, Medical.
inflammation of the retina, generally in both eyes. It results from purulent infection of the retinal vessels caused by sepsis, a purulent focus, tuberculosis or other infectious diseases, or poisoning. Retinitis is usually accompanied by inflammation of the choroid (chorioretinitis). A characteristic development is the appearance of scotomata, or areas of depressed vision within the visual field that correspond to the inflammatory focus in the fundus of the eye. If treatment is inadequate, the depression of vision becomes permanent. Treatment depends on the causative disease.
