• Seven patients with structural abnormalities of one or both of their optic nerves had decreased visual acuity partly due to functional amblyopia. They were treated with conventional amblyopia therapy and their visual acuities improved. Functional amblyopia can coexist either secondary to, or coincidentally with, structural optic nerve abnormalities.
