Ross'syndrome is a rare peripheral nervous system disorder defined by Adie's tonic pupil,hyporeflexia,and segmental anhidrosis.Injury to postganglionic cholinergic fibers is believed to account for the tonic pupil and sweating disturbance.We report a 47-year old man found to have Ross'syndrome in combination with a complete postganglionic Horner's syndrome.Pharmacologic and sudomotor tests in this unique patient provide further evidence that Ross'syndrome results from injury to sympathetic and parasympathetic ganglion cells or to their postganglionic projections. |
