Tetravue Superspeciality Eye Centre is the for HVF Test. The Humphrey visual field is a diagnostic test used to measure visual fields, also known as perimetry. The Humphrey visual field test assesses the entire area of peripheral vision that can be seen while focusing the eye on a central point. Lights of varying intensities appear in different parts of the visual field while the patient's eye is focused on a specific spot during this test. The patient's perception of these lights is charted and compared to the results of a healthy eye at the same age to see if any damage has occurred. This procedure takes about 20 minutes and is useful for diagnosing and monitoring glaucoma. Patients with glaucoma will have this test done on a regular basis to monitor the disease's progression. The Humphrey visual field test can also detect conditions within the eye's optic nerve as well as certain neurological conditions.
