MAIA

The New Frontier of Microperimetry
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.

Microperimetry

Microperimetry is a technology that allows concurrent analysis of structural and functional aspects of the retina. It combines retinal sensitivity mapping and fixation analysis with the fundus image in one exam as a powerful tool to detect, describe and follow-up pathologies affecting the macular area. iCare MAIA performs different types of microperimetry tests with supra and full-threshold strategies, and follow-up tests to monitor functional progression. Each exam provides a measure of retinal sensitivity and fixation analysis (stability and position of the Preferred Retinal Locus).

Benefits of MAIA

  • 25 Hz eye-tracking with confocal SLO imaging
  • Pre-programmed and custom tests
  • Sensitivity and fixation indexes, illustrative sensitivity, and fixation maps
  • Informative examination and progression reports
  • 2.5 mm minimum pupil size
  • Patients with cataract (up to grade 3+) and media opacities can be examined
  • Auto-focus (from -15D to +10D)
  • Sensitive to functional changes due to macular pathologies or treatments even in early stages (background down to <0.0001 asb, threshold range 36 dB)
  • Simple to use, patients can be tested in less than 3 minutes per eye
  • S-MAIA includes also scotopic testing with cyan and red stimuli

Which diseases can be evaluated with MAIA

iCare MAIA is used as a diagnostic device to aid in the detection and management of diseases affecting the macula, including, but not limited to, macular degenerations. Thanks to its combined structure-function analysis, microperimetry represents an essential tool for deriving the correct diagnostic decision in a variety of retinal diseases, monitoring the progression of retinal pathologies, assessing macular function prior to cataract surgery, examining patients with unexplained vision loss and more.
