The authors report the first case of trisomy 18 associated with a clinically detectable optic nerve pit. A female infant with a birth weight of 2,150 g was born by cesarean section to a healthy 40-year-old woman at 38 weeks of gestation. Trisomy 18 had been diagnosed by prenatal genetic testing. Ophthalmologic examination was remarkable for bilateral narrowed palpebral fissures with punctal agenesis, corectopic pupils without reaction to light, bilateral inferior peripapillary retinochoroidal hypopigmentation, and significant optic nerve cupping in the left eye with associated temporal optic nerve pit. It has generally been accepted that optic nerve pits are a congenital anomaly. However, the pathophysiological background of optic nerve pits remains unclear and controversial. This is the first clinical and photographic documentation of an optic nerve pit in a neonate and in Edwards syndrome. [J Pediatr Ophthalmol Strabismus 2013;50:e24–e26.]
