MAIA represents the latest advance in confocal microperimetry. Retinal images are acquired by Scanning Laser Ophthalmoscopy (SLO). The main difference and great advantage over Standard Automated Perimetry is that retinal sensitivity is measured while simultaneously imaging the retina in real time.
MAIA performs different types of microperimetry tests with supra and full-threshold strategies, and follow-up test to monitor functional progression. Each exam provides a measure of retinal sensitivity and fixation analysis (stability and position of the Preferred Retinal Locus). The MAIA sensitivity scale is 0 to 36 dB.
