The Zeiss Visual Field Analyzer utilizes advanced technology to perform precise and detailed measurements of the patient’s visual field. It employs a series of lights or targets that are presented at specific locations within the patient’s visual field while they focus on a central point.
The patient’s responses to the presented lights or targets are recorded, either manually by pressing a button or automatically through eye-tracking technology. The device then generates a visual field plot or map, which displays the patient’s ability to detect the lights or targets at different locations within their visual field.
The visual field plot provides essential information about the extent, sensitivity, and potential defects in the patient’s visual field. It helps identify any areas of reduced or absent vision, which can indicate the presence of eye conditions such as glaucoma, optic nerve disorders, retinal diseases, or neurological abnormalities affecting vision.
The Zeiss Visual Field Analyzer offers various testing protocols and strategies tailored to the specific needs of each patient. These protocols can assess different aspects of visual function, including peripheral vision, central vision, and the ability to detect subtle changes in contrast.
