Optic nerve manifestations of human congenital cytomegalovirus infection
Insights
Cytomegalovirus infection in infants can cause serious vision problems, including optic nerve hypoplasia and coloboma. Early diagnosis and monitoring are crucial for managing these cytomegalovirus-related ocular manifestations.
Area of Science:
- Ophthalmology
- Virology
- Pediatrics
Background:
- Cytomegalovirus (CMV) is a common viral infection that can have significant health implications for newborns.
- Congenital CMV infection is a leading cause of non-genetic sensorineural hearing loss and can also affect other organs.
- Ocular manifestations of congenital CMV infection are not as widely studied but can lead to severe visual impairment.
Abstract:
A Latin American male and a white female infant who had a cytomegalovirus infection on the first day of life had unilateral optic nerve hypoplasia. A white male infant who had cytomegalovirus isolated at 5 weeks of age had a unilateral partial coloboma of the optic nerve. A 4-month-old black infant with cytomegalovirus infection diagnosed at 2 days of age had a unilateral complete coloboma of the optic nerve associated with microphthalmia. Optic nerve involvement was an important manifestation of this disease.
