Abstract:
We report the case of a 4-month-old boy diagnosed with DiGeorge syndrome with novel ocular features. The patient was diagnosed through genetic testing, with a noted 22q11.2 deletion, and had the additional clinical findings of cardiac anomalies, Hirschsprung's disease, and intracranial microhemorrhages. Eye findings included bilateral microphthalmia, persistent fetal vasculature, chorioretinal coloboma, and a unilateral orbital cyst. Given no known additional inciting exposures, a dysgenic mechanism resulting in failed closure of developmental fissures associated with the chromosomal deletion likely gave rise to these combined pathologies.
