Nidek’s MP-1S is a retinal function analyzer that, along with its accurate retinal tracker, correlates fixation data and light-sensitivity map on any selected area of the retina. The MP-1S is designed to obtain multiple retinal analysis on patients with almost any visual acuity level.
Fundus Related Perimetry
The MP-1S improves diagnostic accuracy by quantifying and qualifying functional response of selected retinal areas. The combination of subjective (sensitivity map) and objective (retinography) data is unified on a microperimetry map, allowing a straightforward analysis of the retinal function before and after any clinical or surgical treatment, helping the physician to improve the diagnosis accuracy.
Fixation characteristics are critical for retinal analysis. The MP-1S offers exact fixation quantification, location and stability, ensuring an accurate prediction of treatment results and assisting the physician’s decision to proceed surgically or not.
Administering the exact same exam on exactly the same retina point over time allows qualification of quality of vision after any pharmacological or surgical treatment. Dedicated differential mapping is available to quickly highlight the retinal changes both for microperimetry and fixation exams. This eliminates the possibility of transposition errors when making these calculations.
With the biofeedback exam, low-vision patients who have lost foveal fixation capabilities can be taught relocate their preferred retinal locus (PRL) into a different region. Auditory and visual feedback assist the low vision practitioner in teaching the patient to successfully use a new PRL.
The high-precision kinetic exam of the MP-1S easily finds the shape of a scotomatous area due to rapid identification of the size and shape of even the smallest scotomas.
Different Retinal Technologies
The MP-1S allows overlapping of the sensitivity map on imported images taken with retinal systems performing FAG, ICG, IR, OCT and others. We can also use .jpg, .bmp or .gif images.
