Visual field analyzers are often used in detection and diagnosis of Glaucoma, AMD, Scotomas and brain abnormalities. These analyzers test the full horizontal and vertical field of peripheral vision, identifying potential diminished or blind spots (scotomas) in the patients’ vision. Identifying specific scotomas in ones vision can be indicative of a certain type of brain trauma or disease, such as a stroke or tumor. The patient is directed to identify certain light stimuli provided by the analyzer in their peripheral vision, if the patient is unable to detect the stimuli, then this could indicate trauma and/or scotomas.
These visual field analyzers can offer up to 90? of measurement across the visual field and boast features such as monocular and binocular testing, fast and simple operation, DICOM compatibility as well as EMR connectivity and color and kinetic perimetry to name just a few. Depending on the type of practice, choosing a product that is customizable to your needs is key.
