Description
Summary:A recent model of the defective oculomotor system producing congenital nystagmus emphasizes that the time constant of the slow-phase eye movements of jerk nystagmus represents a useful parameter in the quantification of the effects of the surgical therapy, since it is directly related to the patient's potential for good visual acuity. The authors analyzed preoperative and postoperative electrooculographic records from five patients with congenital nystagmus and estimated the average time constant of the slow-phase eye movements over seven gaze angles for each patient. This model's parameter was shown experimentally to be a valid tool in monitoring the surgical effects, validating the theoretical indications.< >
