Congenital Horner’s Syndrome

Congenital Horner’s Syndrome
This patient manifests miosis and mild ptosis on the right. In addition, the right iris is relatively hypochromic. Both pupils responded normally to light, and the difference in pupillary size was greater in darkness.The development of normal iris pigmentation is contingent upon intact sympathetic innervation. Accordingly, Horner’s syndrome of congenital origin includes iris heterochromia as a clinical feature.
