MAIA represents the latest advance in confocal microperimetry. Retinal images are acquired by Scanning Laser Ophthalmoscopy (SLO). An eye tracker allows accurate, real-time, compensation of eye movements. Luminance levels are compliant with existing standards (1000 asb.).
MAIA is highly automated, very easy to use, non mydriatic and combines the best aspects of its predecessors. Similarly to Standard Automated Perimetry (SAP), MAIA measures light sensitivity of the retina by projecting Goldmann III stimuli over different retinal locations within the field of view. The main difference and great advantage over SAP is that retinal sensitivity is measured while simultaneously imaging the retina in real time.
Retinal images, created by SLO technology, are processed by an eye tracker to calculate and compensate eye shifts (fixation losses) occurring during visual field measurement, in both physiological and pathological conditions. Fixation analysis is the second, fundamental, outcome of of the Maia eye tracker.
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.
