Abstract
To overcome the inconvenience and imprecision of conventional software performing microperimetry with the scanning laser ophthalmoscope (SLO) in clinical settings, we developed a “smart microperimetry” program. It takes advantage of modern computer technology, especially processing speed and high rate of data transfer. It allows continuous on-line processing of the image of the retina and instantaneous correction of stimulus placement according to involuntary eye movements. Thus, the program provides gaze-contingent display of the stimulus and senses the conditions for image tracking so that stimulation during large eye movements, blinks, and temporarily flawed image quality can be prevented. These features have greatly increased the efficiency and precision of SLO data in comparison with those obtained by older programs.
