Algorithm, Swedish Interactive Thresholding (SITA) 

A program designed to shorten the time taken to determine the threshold values of each location of the visual field being tested with an automated perimeter. Stimulus presentation is altered according to the patient's response time, the quicker the patient responds the faster the rate of presentation and vice versa. Patient's reliability is also taken into account.
