Lack of adrenergic influence on the pigmentation of iris nevus cells
T. P. Dryja and D. M. Albert
A 30-year-old woman was found to have iris heterochromia as a consequence
of unilateral congenital Horner's syndrome, Iris nevi were present and were
equally darkly pigmented in either eye. Based on these clinical
observations, we conclude that the absence of sympathetic innervation does
not influence the development and pigmentation of iris nevus cells.
