CMV retinitis

Cytomegalovirus retinitis

Cytomegalovirus (CMV) retinitis is a viral infection of the retina of the eye resulting in inflammation.

Eye

The eye is the organ of sight, a nearly spherical hollow globe filled with fluids (humors). The outer layer or tunic (sclera, or white, and cornea) is fibrous and protective. The middle tunic layer (choroid, ciliary body and the iris) is vascular. The innermost layer (the retina) is nervous or sensory. The fluids in the eye are divided by the lens into the vitreous humor (behind the lens) and the aqueous humor (in front of the lens). The lens itself is flexible and suspended by ligaments which allow it to change shape to focus light on the retina, which is composed of sensory neurons.

CMV retinitis

Cytomegalovirus is a large herpes-type virus commonly found in humans that can cause serious infections in people with impaired immunity. Chorioretinitis, which may cause blindness, is treated with antiviral medications, which may stop the replication of the virus but will not destroy it.
