1 Goldmann machine. Goldmann machine. The patient's eye is positioned at the centre of a white hemispheric bowl, with the examiner looking through an eyepiece to ensure good fixation. A white light (indicated by yellow arrow in (A) is brought in from the periphery into the patient's field of vision. The examiner does this by controlling connecting levers (indicated by orange arrows in A and B). The patient presses a buzzer when the light target is seen (blue arrow).
