Diagnostic
Macular Integrity Assessment maia
The ideal tool for early detection,
follow-up and monitoring of macular diseases.

Thanks to its scanning laser based optical system,
MAIA™ operates with a minimum pupil diameter of 2.5
mm, thus not requiring the use of  dilating drops.

Ergonomic clicker.

MAIA™ offers great ergonomic 4 advantages, in terms of
easy interaction between the operator, the patient and the
device. MAIA’s testing and imaging capabilities are simply
controlled by the use of the touch screen and of a two
buttons keypad.

MAIA™ incorporates an advanced statistical package,
EyedB™, providing an immediate and intuitive comparison
of the results with the corresponding normal values.

* The EYEdBTM uses a neural network multivariate
model that includes age, average threshold value,
a measure of points with threshold below 25 dB
and all measured threshold values.

Presenting maia

MAIA, the new frontier of Fundus Perimetry (microperimetry) assesses the function of the macula representing an effective clinical tool for the early detection and follow-up of macular degenerations and other pathologies of the retina. MAIA incorporates a Line Scanning Laser Ophthalmoscope (SLO), providing clear and detailed retinal images.
Thanks to the EyedB analysis software, MAIA processes the measured data and rapidly evaluates macular function as Normal, Suspect or Abnormal. Through its precise eye-tracker, MAIA also provides a quantitative analysis of the patient’s fixation in terms of stability and location.

Benefits
Ease of Use. Accurate Analysis. Comparative Screening Function. PatientComfort. Patients can be tested in less than 3 minutes per eye. Helps monitoring the course of retinal diseases and the efficacy of treatment. MAIA has proved over 90% sensitivity and specificity in the detection of early and intermediate age related macular degeneration.

Retinal imaging

 

The confocal properties of the scanning laser ophthalmoscope provide high resolution images of the
retina under infrared light throughout the test. Furthermore, opacities of the media, such as floaters in
the vitreous and cataract, do not significantly degrade the image, although they may be visible.
Fast Exam
Expert Exam
4_fast-exam.jpg

For a fast and easy assessment, in less than 3 minutes per eye, MAIA measures 36 points over a 10 degrees
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.

Evaluates macular threshold at multiplemeasurement 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 one. Measurement points can be customized for patient needs.

** Macular integrity can only be shown when standard 10°, 37 stimuli grid is selected.

 

 



Follow-up Exam
Fixation Stability Exam

To measure functional changes due to the 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.

While threshold measurements are taken, the 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).
