Highlights
-
The viral necrotizing retinopathies include acute retinal necrosis, cytomegalovirus retinitis, and progressive outer retinal necrosis. Diagnosis is principally clinical; in uncertain cases, polymerase chain reaction testing can be done.
-
Human infection by Toxoplasma gondii may be either acquired or congenital. Recently acquired disease may present as a focal retinochoroiditis in the absence of a chorioretinal scar.
-
Ophthalmic presentations of ocular toxocariasis include a chronic endophthalmitis (25%), a posterior pole granuloma (25%), or a peripheral granuloma (50%).
-
Viruses, fungi, protozoa, helminths, and bacteria can all cause infectious uveitis, featuring inflammation in different parts of the uveal tract. This chapter is organized according to the causative organism and subcategorized by the anatomical location of inflammation.
