We report a case of a male preterm infant with gestational age of 35 weeks evaluated for retinopathy of prematurity. On examination, the infant showed bilateral advanced optic nerve cupping head with cup disc ratio of 0.9. With a suspicion of optic nerve hypoplasia, the infant was referred to the treating pediatrician for reevaluation and to rule out systemic disorders, cranial hemorrhage, and periventricular leukomalacia. Cranial ultrasound ruled out periventricular leukomalacia. At 39 weeks of gestational age, the infant was re-admitted with the neonatologist for respiratory distress, protuberant abdomen, and tongue fasciculation. Systemic workup revealed hypothyroidism with T3 levels of 0.76 ng/ml, T4 7.1 μg/dl, and thyroid stimulating hormone 0.5 μIU/ml. Congenital hypothyroidism has a known predisposition (43%) for developing optic nerve hypoplasia. We present a unique case of congenital hypothyroidism with optic nerve head cupping presenting as a plausible variant of optic nerve hypoplasia.
