ABSTRACT
Ross syndreome is a rare peripheral nervous system disorder defined by Adie' tonic pupil, hyporeflexia, and segmental anhidrosis. The pathogenesis is believed to result from damage to the ganglion cells or postganglionic fibers, including sympathetic, parasympathetic and dorsal root ganglion cells. A 46 year-old woman complained of right ptosis and decreased sweating of right face. The pupil showed anisocoria, which was evaluated under the variable conditions and recorded with the pupillography using Infrared Scanning Laser Photography(HRA , Heidelberg engineering, Germany). The neurologic examinations including starch-iodine test demonstrated areflexia of lower limbs and hypohidrosis of right face. The above examinations provided evidences that the sympathetic and parasympathetic ganglion cells or the post ganglionic fibers were involved and the diagnosis of Ross syndrome with Horner syndrome was made.
