Purpose: To report a case of bilateral congenital optic disc coloboma associated with the right seventh and eighth cranial nerve palsy.
Case Summary: A female neonate with right facial palsy (seventh cranial nerve palsy) and right earlobe hypoplasia was referred for examination for retinopathy of prematurity (ROP). Bilateral optic disc coloboma and peripapillary choroidal defect was detected on the fundus examination and the anterior segment examination revealed no specific findings. On the otolaryngologic examination, laryngomalacia and floppy epiglottis were observed and left otitis media and mastoiditis were noted on the temporal bone computed tomography (CT). On the auditory brain stem response (ABR), right electro-potential was not detected and right cochlear nerve palsy (eighth cranial nerve palsy) was diagnosed. Further chromosomal analysis and brain magnetic resonance imaging (MRI) revealed no abnormal findings. However, on echocardiography, an atrial septal defect was detected and on upper gastrointestinal series, gastroesophageal reflux disease (GERD) was diagnosed.
Conclusions: Congenital optic disc coloboma is frequently accompanied by other congenital deformities or abnormalities, and therefore, systemic examinations and tests to detect associated findings are required.
