Eye movements recording systems

Metrovision offers eye-movement recording using video-oculography and electro-oculography techniques. Its video-based approach can record ocular movement without requiring a helmet, supporting a range of oculomotor examinations.

• Metrovision's VOG technique does not require a helmet and is easily adaptated to most patients. However, the access to the pupil images is necessary and the use of VOG may be limited in some circumstances (tests performed with closed eyes, patients with difficulties opening the eyes, presence of tears)
• EOG allows recording eye movements in almost every patient despite the use of electrodes. However results may be less accurate than with VOG because of artefacts such as electrode drifts, blinks
• The equipment is controlled from a standard high-performance PC under Windows 11 PRO
• Tests are presented at a distance of 30 cm from the eyes
• In addition, a large display monitor can also be used to perform EOG exams at a distance of 1 meter
