A seven-dаy-оld mаle infаnt was examined by a pediatric оphthalmоlogist in the physician’s office. The child had been recently discharged from the hospital after birth. He was the product of a full-term gestation and his mother had an uneventful prenatal period. Based on physical findings and testing, the male infant was diagnosed with translocation Trisomy 13.In order to rule out a retinoblastoma, the infant was referred for this examination. The external examination of the lids was normal. There was haziness overlying the limbus superiorly in both eyes, consistent with an anterior embryotoxon, a congenital corneal malformation. The pupils dilated readily. The lenses were clear. The vitreous was clear. Examination of the fundus revealed normal-appearing disks and macular blood vessels with no evidence of any lesion. The consultant wrote the diagnoses on the report returned to the primary pediatrician as “Bilateral anterior embryotoxon, otherwise normal examination with no evidence of retinoblastoma in this newborn infant with translocation Trisomy 13.” First-Listed Diagnosis: Secondary Diagnosis:
