Kyrieleis plaques in cytomegalovirus retinitis.
Summary of "Kyrieleis plaques in cytomegalovirus retinitis."
The purpose of this study is to report a case of Kyrieleis plaques (segmental retinal periarteritis) associated with cytomegalovirus (CMV) retinitis.
A 47-year-old female with recently diagnosed human immunodeficiency virus and a CD4 count of 55 cells/µl presented with decreased vision and floaters in her left eye. Ophthalmic examination revealed an advancing border of white granular CMV retinitis extending into the macula. Intraocular aqueous specimen contained 420,000 copies/ml of CMV DNA by polymerase chain reaction. The patient was treated with intravitreal foscarnet and oral valganciclovir.
Kyrieleis plaques involving the retinal arteries were noted on presentation and increased during the first 6 weeks of treatment as the retinitis faded. The plaques on fluorescein angiography did not leak fluorescein dye and slowly faded over 5 months.
Kyrieleis plaques can be seen in the setting of CMV retinitis. These plaques can be differentiated from vascular sheathing and frosted branch angiitis by its occurrence only in the retinal arteries and the absence of leakage of fluorescein dye.

Cytomegalovirus (CMV) retinitis continues to be a leading cause of blindness in many developing countries. Telemedicine holds the potential to increase the number of people screened for CMV retinitis,...
The incidence of cytomegalovirus retinitis has decreased significantly since the advent of antiretroviral therapy. However, it remains an important problem in both the developed and developing worlds....
To study the outcomes of treatment with intravitreal ganciclovir injection for cytomegalovirus (CMV) retinitis in patients without Human Immunodeficiency Virus (HIV) infection.
Purpose:Retinitis induced by both human and murine cytomegaloviruses following immunosuppression is characterized by progressive loss of retinal architecture, due to necrosis of virus infected cells a...
The purpose of this study is to see if it is safe and effective to give Viracept to AIDS patients who are already being treated for cytomegalovirus (CMV) retinitis.
The purpose of this study is to see if valganciclovir is a safe treatment for CMV retinitis in patients who have been treated for this condition in the past. This study also examines the e...

Medical and Biotech [MESH] Definitions
Infection of the retina by cytomegalovirus characterized by retinal necrosis, hemorrhage, vessel sheathing, and retinal edema. Cytomegalovirus retinitis is a major opportunistic infection in AIDS patients and can cause blindness.
An antiviral agent used in the treatment of cytomegalovirus retinitis. Foscarnet also shows activity against human herpesviruses and HIV.
An ACYCLOVIR analog that is a potent inhibitor of the Herpesvirus family including cytomegalovirus. Ganciclovir is used to treat complications from AIDS-associated cytomegalovirus infections.
Infection with CYTOMEGALOVIRUS, characterized by enlarged cells bearing intranuclear inclusions. Infection may be in almost any organ, but the salivary glands are the most common site in children, as are the lungs in adults.
A genus of the family HERPESVIRIDAE, subfamily BETAHERPESVIRINAE, infecting the salivary glands, liver, spleen, lungs, eyes, and other organs, in which they produce characteristically enlarged cells with intranuclear inclusions. Infection with Cytomegalovirus is also seen as an opportunistic infection in AIDS.
