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.
HOW VISUAL FIELD TESTING HELPS IDENTIFY EYE ISSUES
Many eye and brain disorders can cause peripheral vision loss and other visual field abnormalities. Visual field tests are performed by eye care professionals to detect blind spotscotomas and other visual field defects, which can be an early sign of these problems.
The size and shape of a scotoma offer important clues about the presence and severity of diseases of the eye, optic nerve and visual structures in the brain. For example, optic nerve damage caused by glaucoma creates a very specific visual field defect. Other conditions associated with blind spots and other visual field defects include diseases of the retina, optic, neuropathy, brain tumors and stroke.
During a routine eye exam, your optometrist or ophthalmologist may recommend visual field testing to assess the full horizontal and vertical range and sensitivity of your vision. These “baseline” visual field test results can then be used to assess potential changes in your visual field in the future.
