Viral Uveitis
Lymphocytic Choriomeningitis Virus
Lymphocytic choriomeningitis virus (LCMV) is an under-recognized fetal teratogen that should probably be listed among the “other agents” in the TORCH group of congenital infections. The microbe is a single-stranded RNA virus of the Arenaviridae family.
Systemic findings include macrocephaly, hydrocephalus, and intracranial calcifications. Neurologic abnormalities, seizures, and mild cognitive impairment may occur. Ocular findings include macular and peripheral chorioretinal scars, similar in morphology and distribution to congenital toxoplasmosis. Serologic testing of the mother and the infant helps differentiate. Other findings include optic atrophy, strabismus, and nystagmus.
