The MDT EH-1 Hess Screen is a diagnostic device designed for eye muscle coordinometry testing, particularly for the assessment of paralytic strabismus and eye muscle paralysis or paresis. The examination is based on detecting the apparent displacement of a test point associated with the action of a paralysed or weakened eye muscle.
The screen features a fixed grid formed by intersecting parabolic lines, with 25 green LED test points positioned at the intersections. During the examination, the doctor selects individual points in random order, while the patient indicates the perceived location of each illuminated point. The results can be used to assess ocular motility and identify abnormalities in eye muscle function.
