Magnification. The Brushfield spots are the spots between the inner and outer red circles.

Brushfield spots are small white or grayish/brown spots on the periphery of the iris in the human eye due to aggregation of connective tissue, a normal iris element. These spots are normal in children (Kunkmann-Wolffian bodies) but are also a feature of the chromosomal disorder Down syndrome. They occur in 35-78% of newborn infants with Down syndrome.[1] They are much more likely to occur in Down syndrome children of the Caucasian race than children of Asian heritage.[2] Brushfield spots are named after the physician, Thomas Brushfield, who first described them in his 1924 M.D. thesis.[3]

They are focal areas of stromal hyperplasia, surrounded by relative hypoplasia and are more common in patients with lightly pigmented irises.
