MAIA™ provides the first step in retinal disease management, enabling you to test macular function and to follow sequential changes of retinal disease and/or treatment over time. Featuring a confocal line Scanning Laser Ophthalmoscope (SLO), real-time eye-tracker and 4-2 threshold fundus perimetry (microperimetry), MAIA™ provides quick and accurate assessment of macular function, including; macular sensitivity, fixation stability and the point of fixation. The system’s unique SLO technology captures clear and detailed confocal images of the retina on a scale so precise that structures commonly missed by fundus cameras, such as macular drusen and holes, are visualized. MAIA™ is also equipped with threshold sensitivity analysis software, enabling it to accurately and precisely measure and monitor functional changes compared to an age-related database of ‘normal’ reference values. This permits the differentiation of normal age-related loss of macular sensitivity from pathological changes that require treatment.

MAIA™ offers three different testing modes designed to facilitate the monitoring of disease progression or treatment effect over time.
Mode 1: Fast Test
Mode 2: Expert Test
Mode 3: Follow-Up Test 

MAIA™ offers a number of benefits, including:

  • Fast: Suprathreshold testing in three minutes or less
  • Ease of Use: Easily quantify patient’s preferred retinal locus of fixation (PRL)
  • Full threshold and follow-up testing to accurately show changes and fixation stability due to the disease or retinal treatment
  • Sequential monitoring of the disease for greater peace-of mind
  • MAIA has shown over 90% sensitivity and specificity in the detection of early and intermediate Age-Related Macular Degeneration

 

 

Fast Test

For a fast and easy assessment in less than three minutes per eye, MAIA™ measures 36 points over a 10 degree area to evaluate the sensitivity of the macula. The included EyedB software compares the results with a reference database of normal subjects to provide color-coded outcomes. Click the thumbnail for a larger view.

Expert Test

MAIA™ evaluates macular threshold at multiple measurement points for a complete and detailed test. Results include functional indices for macular threshold and fixation stability. Multiple measurement grids can be selected in addition to the standard grid, with measurement points customizable depending on individual patient needs. Click the thumbnail for a larger view.

Follow-up Test

To measure functional changes due to disease and/or retinal treatment, MAIA™ accurately re-tests the same points that have been measured in the baseline test and outputs a graph of the results, plotting the sequential changes in macular sensitivity and fixation stability.

Fixation Stability Test

While threshold measurements are taken, the MAIA’s built-in eye-tracker simultaneously monitors fixation, hence allowing automated compensation of eye movements during the test – and conversely providing a quantification of the patient’s fixation stability and preferred retinal locus of fixation (PRL). The findings are presented in an easy-to-read graph that ensures that changes over time are clearly visible. Click the thumbnail for a larger view.
