On the Eyesi Slit Lamp touch screen interface, trainees can control the examination settings. A diffusor can be activated for observation under diffuse illumination, fluorescein can be applied, and the eyes may be dilated to facilitate lens or retinal examinations. The virtual patients can be set to keep their eyes closed, blink or stop blinking, fix their gaze, or look in a specific direction. Trainees can evert the patient’s eyelids by touching corresponding sensor fields on the patient model head.
