A 6-year-old mentally challenged male child with a history of intra-uterine growth restriction, congenital heart disease with patent ductus arteriosus, and microcephaly was brought to the hospital for an eye examination. He was a case of Noonan syndrome with ocular features suggestive of an atypical rubella retinopathy with pale discs in both the eyes [Fig. 1a-d]. Blood work-up during newborn intensive care unit hospitalization revealed a positive rubella IgG (10.3IU/ml) and negative IgM. The distinctive feature in our case is the extensive nature of the pigmentary retinopathy obscuring the normal course of the retinal vessels and the presence of multiple large subtle choroidal excavations as well as retinal pigment epithelium (RPE) atrophy. Only one case of retinopathy (a Coats-like disease) has been documented in a cohort of 105 cases with ophthalmic manifestations in Noonan syndrome.[1] Large choroidal excavation is a rare finding in a patient with rubella retinopathy.[2] We present a unique association of rubella retinopathy in a child of Noonan syndrome.
