[Cytomegalovirus retinitis]
Abstract:
Cytomegalovirus (CMV) retinitis is the most common intraocular infection in patients with Acquired immunodeficiency syndrome (AIDS). Approximately 25% of patients with AIDS will develop CMV retinitis during their life time. It is generally associated with CD4+ lymphocyte counts of less than 50 cells/microliter. Clinically, the most characteristic feature of CMV retinitis is a yellow-white lesion of retinal necrosis with a granular border extending into the surrounding retina. At present, ganciclovir and foscarnet have been approved for the treatment of CMV retinitis in patients with AIDS. Although both drugs arrest the progression of retinitis, relapse often occurs. More than ever, ophthalmologists have a special obligation to alleviate both the physical and psychological suffering of patients with CMV retinitis.
Insights
Cytomegalovirus (CMV) retinitis is a common eye infection in patients with Acquired immunodeficiency syndrome (AIDS), often occurring with low CD4+ counts. Current treatments like ganciclovir can halt progression but frequently lead to relapse, necessitating ongoing care.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Virology
Context:
- Cytomegalovirus (CMV) retinitis is the most frequent intraocular infection in individuals with Acquired immunodeficiency syndrome (AIDS).
- Occurrence is typically linked to CD4+ lymphocyte counts below 50 cells/microliter.
- About 25% of AIDS patients develop CMV retinitis in their lifetime.
Purpose:
- To describe the clinical characteristics, prevalence, and current treatment of Cytomegalovirus (CMV) retinitis in patients with Acquired immunodeficiency syndrome (AIDS).
- To highlight the limitations of current therapies and the ongoing need for effective management strategies.
Summary:
- CMV retinitis presents as yellow-white retinal necrosis with granular borders.
- Ganciclovir and foscarnet are approved treatments that can halt retinitis progression.
- Relapse is common despite treatment, indicating a need for improved therapeutic approaches.
Impact:
- Emphasizes the significant burden of CMV retinitis in the AIDS population.
- Underscores the challenges in managing CMV retinitis due to frequent relapses.
- Highlights the critical role of ophthalmologists in managing the physical and psychological well-being of affected patients.
