MonCV3: a Comprehensive Medical Perimeter for Visual Exploration
Metrovision's MonCV3 is a multifunctional perimeter designed to meet the most demanding clinical needs in ophthalmic diagnostics. This device combines several essential protocols for visual field testing and overall visual function assessment in a single compact unit. It enables standard automated static perimetry, an essential tool in the screening and monitoring of chronic conditions such as glaucoma. As an option, the MonCV3 also supports manual Goldmann perimetry, blue/yellow perimetry and motion perimetry, each providing additional clinical information. Blue/yellow perimetry is particularly suitable for the early detection of glaucomatous deficits, while motion perimetry improves sensitivity to magnocellular system damage and reduces artefacts related to ocular media or refractive blur.
A Design Focused on Clinical Accuracy
The MonCV3 has been designed to offer optimal accuracy in visual field assessment. It features a high-resolution screen with rigorously calibrated luminance and contrast, enabling reliable examinations in all conditions. The central field is analysed up to 30° of eccentricity, and the use of offset fixation points extends the exploration to 60°. Additional light sources placed on the horizontal meridian allow extension to 75° of eccentricity. The device also uses a near-infrared camera to track the gaze during the examination, ensuring reliable results. This camera can record eye movements and pupil diameter, which are essential in certain neuro-ophthalmological conditions. An optional high-speed camera can be added to accurately study the delay and speed of saccades.
Additional Tests for a Comprehensive Assessment
The MonCV3 is not limited to perimetry. It also offers a wide range of additional tests for in-depth exploration of visual abilities. For example, the device can measure adaptation to darkness and light using Ganzfeld technology, quantify contrast sensitivity using sinusoidal grids with controlled spatial frequency, and perform standardised visual acuity tests (Landolt, ETDRS) at different distances. The glare test is made possible by very high-intensity light sources (> 20 000 cd/m²), which are essential for assessing discomfort experienced in everyday life. Metamorphopsia and macular pigment examinations complete the range, enabling accurate monitoring of retinal and macular pathologies. The MonCV3 is therefore a comprehensive device for ophthalmology, neuro-ophthalmology and clinical research, offering a comprehensive and reliable assessment of patients' visual functions.
