MonCV3
Brand : Metrovision – France
MonCV3 is a multifunction system combining, in a unique compact apparatus, several tests needed for a complete, throughout evaluation of visual functions.
MonCV3 performs conventional perimetry as well as F.A.S.T. perimetry (Fiber Adapted Static Testing Perimetry) that relies on a specific arrangement of testing points corresponding to the most frequent alterations of the retina and optic nerve fibers. These exams are designed to provide a maximum of clinically useful information within the minimum amount of time.
MonCV3 can perform, as options, blue over yellow perimetry and motion perimetry as well as other tests such as visual acuity, vision tests under low contrast and low luminance conditions, glare test, macular pigment density, pupillometry, attention visual field
Visual field exams
MonCV3 includes a high resolution monitor with calibrated luminance and contrast which is used to test the central visual field, up to 30 degrees of eccentricity. By shifting the fixation spot, the peripheral field can be tested up to 60 degrees of eccentricity. Additional light sources are placed along the horizontal meridian and allow the evaluation of the horizontal limits up to 75 degrees of eccentricity.
Video monitoring
MonCV3 includes a high resolution, near infra-red video sensor which is used to monitor the fixation of the patient, and to measure the pupil size (option)
Blue/Yellow perimetry
The apparatus can generate blue color tests with Goldmann size V which are projected over a high luminance yellow background (100 cd/m²), for the detection of early glaucoma deficits.
Motion perimetry
Motion stimulation has increased sensitivity for the detection of deficits of the magnocellular system (glaucoma).
Motion stimulation is also less sensitive to optical factors and allows reducing artifacts due to ocular media diffusion and refractive blur.
Visual aptitudes: visual acuity, Landolt and ETDRS
LANDOLT and ETDRS tests for visual acuity are performed at distances of 1 m, 2.5 m and 4 m.
The optotype luminance is 100 cd/m2.
The contrast sensitivity tests are performed with sinusoidal gratings with controlled spatial frequencies, luminance and contrast.
For the glare test, the instrument is equipped with sources of very high luminance (> 20 000 cd/m2) positioned on the side of the screen.
