Background: Cytomegalovirus (CMV) is the most common congenital viral infection in the United States. Visual and ocular sequelae in adolescents and adults who are congenitally infected with CMV have not been well studied. Better understanding of the long-term visual and ocular sequelae can help with early detection, intervention and appropriate educational accommodations. Methods: This study evaluated 237 patients (77 symptomatic, 109 asymptomatic and 51 control) who underwent a series of age-appropriate ophthalmologic, audiologic and neurodevelopmental examinations from 1982 to 2013. The frequency and etiology of visual impairment and other nonophthalmologic findings were recorded for each patient. Ophthalmologic findings were tabulated, and risk factors for abnormalities were analyzed. Results: Fourteen of the 77 (18.2%) symptomatic and none of the asymptomatic and control subjects had severe visual impairments (P ≤ 0.006). Moderate visual impairment did not differ between symptomatic and asymptomatic subjects. Three asymptomatic subjects had retinal scars. The most common visual or ocular sequelae in the symptomatic group were strabismus (23.4%), chorioretinal scars (19.5%), cortical visual impairment (14.3%), nystagmus (14.3%) and optic nerve atrophy (11.7%). Three symptomatic patients had delayed visual deterioration because of later occurring retinal disorders: peripheral retinal scar, rhegmatogenous retinal detachment and Coats’ disease. Conclusion: Symptomatic CMV patients experienced more ophthalmologic sequelae and significantly worse visual outcomes than asymptomatic CMV and control patients. Later occurring retinal disorders were found in symptomatic patients, and there is no clear evidence that CMV can reactivate in the retinas of children who were congenitally infected. Major risk factors for severe visual impairment included symptomatic status, optic nerve atrophy, chorioretinitis, cortical visual impairment and sensorineural hearing loss.

Congenital cytomegalovirus (CMV) infection has been called “the elephant in our living room” because it is a major public health problem that for decades has been unrecognized and unaddressed. Congenital CMV infection is a common cause of sensorineural hearing loss, vision loss, neurodevelopment disabilities, liver disease, and growth failure. Diagnostic tests are now widely available to identify newborns with congenital CMV infection, congenitally infected newborns now can be easily assessed for evidence of organ involvement, and there are now antiviral treatments and other interventions available to improve the outcome in children with congenital CMV disease. A licensed vaccine to prevent CMV infection is not yet available; however, a “CMV knowledge vaccine,” composed of “an ounce of CMV awareness and three simple precautions” and that is endorsed by the Centers for Disease Control and Prevention is available for pregnant women who wish to reduce their contact with potentially CMV-infected secretions and therefore reduce their risk of acquiring CMV during pregnancy. Medical experts in the field of congenital CMV have been called upon for a consensus statement for diagnosis and treatment, and nonprofit organizations of families affected by congenital CMV from around the world have formed a collaborative coalition to facilitate the spread of CMV knowledge and awareness.

We sought to understand long-term retrospective parental perceptions of the utility of newborn screening in a context where many affected children never develop sequelae but where intensive support services and ongoing healthcare were provided. We conducted focus groups and interviews among parents (N = 41) of children with congenital CMV who had been enrolled in a long-term follow-up study at a large medical college for a mean of 22 years following diagnosis. Groups included parents whose children were: symptomatic at birth; initially asymptomatic but later developed sensorineural hearing loss; and who remained asymptomatic into adulthood. With proper follow-up support, newborn CMV screening was viewed positively by parents, who felt empowered by the knowledge, though parents often felt that they and healthcare providers needed more information on congenital CMV. Parents in all groups valued newborn CMV screening in the long term and believed it should be embedded within a comprehensive follow-up program. Despite initial distress, parents of CMV-positive children felt newborn CMV screening was a net positive. Mandatory or opt-out screening for conditions with variable presentations and treatment outcomes may be valuable in contexts where follow-up and care are readily available.
