<h1>Cytomegalovirus (CMV) retinitis</h1>

Cytomegalovirus (CMV) retinitis is the most common cause of blindness in patients with acquired immunodeficiency syndrome (AIDS).
It is seen commonly when CD4 cells count falls below 50/cmmm.
Retinal vascular inflammation and attenuation are components of the retinitis.
Hazy vitreous, optic nerve pallor and retinal pigmentary changes,cellophane maculopathy, cystoid macular edema, Significant anterior and posterior vitreous cells,optic nerve head neovascularization has been reported in a patient with inactive CMV retinitis and immune recovery vitritis, without evidence of capillary nonperfusion on angiography. A case of optic disk neovascularization after branch retinal vein occlusion and branch retinal artery occlusion in association with HIV and CMV retinitis was also reported
Optic disk neovascularization was reported in a patient with inactive CMV retinitis without capillary nonperfusion and with immune recovery vitritis.
As the CMV retinitis resolves, atrophy of the retinal vasculature develops. Retinitis resolves with anti-CMV therapy.
CMV retinitis is a common cause of rhegmatogenous retinal detachment ( RD ).In this, a few breaks form in thinned out retina & leads to RD.
Other viruses which infect HIV cases are-
. Herpes simplex & zoster
. Molluscum contagiosum
