Visual Field Testing
Information about the visual fields can be obtained in very young patients, once visual fixation has developed (usually by 4 months of age). A peripheral target is presented while the child is fixating on an interesting central target. Movement of the eyes toward the peripheral target (an evoked saccade) confirms the field. Confrontation visual fields can be approximated in children old enough to identify fingers placed in each peripheral quadrant. School-aged children can often be evaluated with manual or automated perimetry.
