Two cases of CHARGE syndrome with multiple congenital anomalies.

We report on two cases of bilateral chorioretinal colobomas with ocular anomalies in patients with CHARGE syndrome. In the first case, a female infant was born at 36 + 5 weeks gestation. At birth, the patient demonstrated a small left eye. Slit-lamp examination revealed colobomas of both irises. Fundus examination showed both chorioretinal colobomas. Brain magnetic resonance imaging (MRI) showed left microphthalmia. Systemic evaluation revealed multiple congenital anomalies: benign external hydrocephalus, esophageal atresia with imperforate anus, atrial septal defect (ASD), ventricular septal defect, patent ductus arteriosis (PDA), and right mild hydronephrosis. In the second case, a male infant was born at 39 + 5 weeks gestation and demonstrated a dysmorphic appearance with an irregular left pupil and ptosis. Fundus examination of both eyes showed large chorioretinal colobomas involving the optic disc and posterior pole. The patient had multi-organ anomalies: right facial palsy, a left short, wide ear with a small lobe, congenital heart defects, such as ASD and PDA, left renal atresia, seizure disorder, and micropenis. Both cases revealed multiple anomalies including nearly all major and minor criteria of CHARGE syndrome which could be life-threatening to neonates. Thus, all neonates with ocular colobomas should have fully and detailed systemic examinations checking all minor criteria and even occasional findings of CHARGE syndrome.
