Teller acuity cards are sufficiently sensitive for early detection of deficits in the presence of defects of the entire visual system. The infant is shown a card with the same background brightness. The examiner is hidden behind a viewing case that covers him or her from the front and side. An observation pinhole in the middle of the card permits the examiner to observe only the infants eyes and determine upon which side of the card the infant is fixating. Infants who prefer the striped side have good fixation.
