Automated perimetry is a diagnostic tool used in ophthalmology and optometry to assess the visual field. This technology employs a computerized device that presents light stimuli at various points within a patient’s field of vision. Responses to these stimuli are recorded, creating a map that identifies areas of visual sensitivity and any potential defects or blind spots. For instance, it can detect scotomas, which are areas of partial or complete vision loss surrounded by areas of normal vision.
Visual field testing is crucial for diagnosing and monitoring a range of ocular and neurological conditions. Early detection of visual field changes can be instrumental in managing conditions like glaucoma, optic neuritis, stroke, and brain tumors. Regular testing allows ophthalmologists to track the progression of these conditions and adjust treatment plans as needed. Historically, visual field assessments relied on manual techniques, which were often subjective and less precise. The development of automated perimeters marked a significant advance in diagnostic capabilities, providing more accurate and reliable data.
