Considerations when renting or leasing a visual field analyzer
Visual fields are equipped with advanced, computerized features that can detect even the most subtle changes in a patient’s vision. While they are mostly used to diagnose glaucoma, or disprove its existence, visual fields are also used to test a range of other eye functions as well. Visual fields come with the ability to detect retinal diseases such as pigmentosa, as well as any conditions that might affect the optic nerve. Visual fields also include a large screen for the examiner to see the readings in real time. These machines are typically equipped with a chin rest to keep the patient comfortable while the test is going on, as well as a non-invasive way to take readings of the patient’s vision and eye structures.
