Profile: Metrovision provides instruments for measuring eye movements. Our products include visual field, attention visual field, contrast sensitivity, dark adaptation, metamorphosia, sweep VEP, electrodes, pupillometry, electro nystagmography Visioboard. Our cupola stimulator is entirely compatible with the goldmann standard & also includes a projection system with a mirror controlled by microstepping motors. Our sweep-vep program is designed for estimating visual acuity in subjects whose cooperation is insufficient to perform long lasting examinations. The sweep VEP technique uses a pattern stimulus which is alternated at a high temporal frequency rate (in the range of 5 to15 Hz), producing a steady state response.
