Causes A conduction defect in one optic nerve causes the afferent pupillary defect, but it does not account for unequal pupils, which is a separate entity that requires additional explanation if it occurs.

The afferent pupillary defect (Marcus Gunn pupillary escape phenomenon) depends on the light-reduction response that occurs in the presence of a conduction defect in the optic nerve.
