The red points in the gaze map highlight this line of vision. Cause: This error message is shown if the patient is not looking at the hexagon on the camera face.
- Page 8 d) Pupils too small! In this example, the pupils are smaller than 3.0 mm. Cause: This error message is shown if one or both pupil diameters are smaller than 3.0 Reason: The pupil reflexes will be underexposed if the pupils are too small. In this case, the measurement will be interrupted inconclusively.

Note: The error message “Pupils not found!” can have many other causes (e.g. scars on the cornea, media opacities, cataracts, keratoconus, retinal detachments, etc.). For this reason, the camera image must be checked in case of this error message.
