Visual field

The Humphrey Field Analyzer III from Zeiss, is a tool for measuring the human visual field, is used by optometrists, orthoptists and ophthalmologists, particularly to detect the monocular visual field. The Analyzer results identify the type of vision defect.

Visual field or campimetry is a non-invasive functional exploration test of the sensitivity of your visual field. It is essential in glaucoma, since the progressive loss of nerve fibers in the optic nerve results in the loss of certain areas of the visual field. It is also essential for use in many neuro-ophthalmological diseases. The function of visual field exploration is to discover these "blind" areas, locate them and measure their extension. In glaucoma, the involvement of the visual field usually begins in the nasal peripheral field and in most cases of incipient or moderate glaucoma, it is practically impossible for the patient to notice the appearance of the blind area without performing computerized campimetry.
