Spontaneous cytomegalovirus mononucleosis with conjunctivitis

Area of Science:

• Ophthalmology
• Virology
• Infectious Diseases

Background:

• Cytomegalovirus (CMV) is a common virus that can cause various syndromes in immunocompetent individuals.
• Mononucleosis syndrome, often associated with Epstein-Barr virus, can also be caused by CMV.
• Conjunctivitis is an inflammation of the conjunctiva, with diverse etiologies.

Observation:

• CMV was successfully isolated from the conjunctival sample of a patient presenting with mild unilateral catarrhal conjunctivitis.
• The patient, a previously healthy adult, exhibited clinical manifestations consistent with CMV mononucleosis syndrome.
• Diagnosis was corroborated by a significant increase in complement fixation antibody titers, confirming active CMV infection.

Findings:

• This case report documents the presence of Cytomegalovirus in the conjunctiva of an adult experiencing symptoms of CMV mononucleosis and conjunctivitis.
• The isolation of CMV directly from the conjunctiva provides evidence of ocular involvement in this specific case.

Implications:

• Further prospective research is warranted to ascertain the prevalence of conjunctival involvement in CMV mononucleosis.
• Investigating the relationship between CMV conjunctivitis and sporadic cases of conjunctivitis could refine diagnostic approaches.
• Understanding the spectrum of CMV manifestations is crucial for comprehensive patient management.
