Summary
Cytomegalovirus (CMV) retinitis remains a vision threat for human immunodeficiency virus (HIV) patients, despite combination anti-HIV therapies reducing its incidence. This review details CMV infection, its pathogenesis, and clinical management strategies.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Virology
Background:
- Cytomegalovirus (CMV) retinitis incidence has decreased in human immunodeficiency virus (HIV)-infected individuals due to combination antiretroviral therapy.
- Despite reduced incidence, CMV retinitis remains a significant cause of vision loss in the HIV-positive population.
Purpose of the Study:
- To review the general characteristics of CMV infection.
- To discuss the specific pathogenesis, clinical manifestations, and available treatment options for CMV retinitis.
Main Methods:
- Literature review of CMV infection and retinitis.
- Synthesis of information on pathogenesis, clinical features, and treatment.
Main Results:
- CMV infection is a common opportunistic infection in immunocompromised individuals.
- CMV retinitis presents with characteristic retinal findings and can lead to severe visual impairment.
Conclusions:
- Understanding CMV infection and retinitis is crucial for managing vision-threatening complications in HIV patients.
- Current treatment strategies aim to control viral replication and preserve vision, but ongoing research is needed.
