The MP-3 is utilized for conducting the microperimetry exam, which is a highly precise diagnostic procedure employed for the functional analysis of retinal photoreceptor cells, including cones and rods, in both photopic and mesopic conditions. This examination is complemented by a color photograph of the fundus, where the results overlay for enhanced comprehension.

Description

Revolutionize Eye Care with MP-3 Microperimeter: 3D Tracking, Efficient Rehabilitation, and Multimodal Analysis for Enhanced Visual Precision

The MP-3, a sophisticated microperimeter, is equipped with a 3D eye tracking system and a non-mydriatic fundus camera, designed for microperimetry examinations to evaluate the sensitivity of retinal photoreceptor cells. With a light intensity range from 0 to 34 dB and a maximum luminance of stimuli at 10,000 abs, it allows for the detection of even the lowest sensitivities.

Featuring a real-time 3D eye tracking system, the MP-3 precisely positions light stimuli on the retina, reducing patient fatigue due to its swift operation. During the examination, the stability of fixation is analyzed, providing comprehensive diagnostic information and monitoring the patient's rehabilitation progress. This efficient examination can be completed in just 40 seconds, with results presented on 2° and 4° circles or in BCEA (Bivariate Contour Ellipse Area).

For patient follow-up and rehabilitation, the device autonomously tracks and aligns itself to the patient's eye using marks from the fundus, ensuring accurate matching with fundus photography. This technology enables the quantification of sensitivity evolution by comparing identical test zones during follow-up, with the second examination automatically conducted under the same conditions as the first.

Active patient rehabilitation, particularly beneficial for those with low visual acuity, is streamlined and optimized through auditory guidance (beeps) and additional visual stimulation (flickering). This feedback-driven approach reduces rehabilitation session durations to just 10 minutes, significantly improving efficiency.

For in-depth analysis, the NAVIS-EX software interface offers an intuitive display of results and allows users to fully customize the examination, including a 100%-adjustable stimuli grid. The software facilitates easy superimposition of microperimetry results onto patient OCT exams, enabling a comprehensive multimodal analysis. Additionally, a similar Humphrey gray scale is available for result comparisons with classical visual field devices.
