Purpose The majority of visual field testing equipment is designed for monocular tests only: most instruments do not have the capability to visualize both eyes simultaneously and many do not have a head rest position suitable for binocular testing. This presentation will focus on the clinical applications of the binocular visual field tests available on the MonCv ONE perimeter. Methods Binocular testing is very important for functional evaluations. Extrapolation from monocular tests is inaccurate as phenomenons such as integration, suppression, ocular deviation, cyclotorsion, … affect differently monocular and binocular vision. The MonCv ONE perimeter combines a binocular video sensor with the possibility of video recording to the possibility of controlling the exam with an interactive mode similar to the Goldmann perimeter. Results Clinical examples of binocular perimetry will be presented including ‐ the evaluation of ptosis with a documentation of the gain in visual field area in relationship with the opening of the eye lids. ‐ the assessment of low vision with the Esterman technique ‐ the evaluation of drivers’ visual field in agreement with the European Community directive ‐ the evaluation of the field of single vision with the determination of a diplopia score‐ the test of the visual field in young infants when eye occlusion and head immobility are not easily obtained Conclusions These examples demonstrate the clinical usefulness of binocular visual field testing with video recording
