Spherical perimeter PERITEST-300
Visual field analyzer (spherical perimeter) “Peritest-300” The Peritest-300 visual field analyzer is designed to determine the boundaries of the visual field, assess light sensitivity within the visual field in daytime, twilight and night vision conditions. "Peritest-300" is necessary for the early diagnosis of glaucoma, various pathologies of the retina and optic nerve. Makes it possible to examine the central and peripheral field of vision in fast (30%), reduced (50%) and full (100%) volume modes. The identified pathologies are divided into groups: normal, relative scotomas of the 1st and 2nd levels, absolute scotomas. The results of perimetry are printed out in the form of a standard form and are permanently stored in the computer archive. Stimulus color: yellow. If necessary, you can choose a different incentive color (white or green); to order, contact the manager. There can only be one color (yellow by default). Software “Peritest-300” can be connected to a computer via a USB connector (the computer must be purchased separately). The computer must have Windows OS installed. After installing the program, the doctor will be able to: work in manual or automatic mode; automatically determine the light sensitivity thresholds of each eye before starting the main study; independently and very easily create your own medical examination programs for the patient (you only need to indicate the coordinates of the examination points); store research results in a convenient database. There are 18 programs for perimetry, including: Program "Color perimetry" (for the central field of vision). A program for determining the critical flicker fusion frequency (CFF) for peripheral vision. A program for determining the timing of sensorimotor reactions to peripheral stimuli. “Eye Muscle Trainer” program (for the treatment of strabismus). Application of "Peritest-300" "Peritest-300" can be used in ophthalmological, neurological, neurosurgical offices of a wide outpatient network, hospitals and research institutes.
