Visual Field Analyzer

Visual Field Analyzers are essential tools used to measure and evaluate different metrics concerning the visual field. More specifically, with the eyes directed straight-ahead and various stimuli projected on a curved surface, the Visual Field Analyzer indicates when the sensation of sight is produced.

Visual Field & Visual Field Analyzers can help ophthalmologists determine each eye’s capability. Test results are typically recorded separately, for each eye, and displayed on a polar-coordinates graph, which uses a continuous curve to illustrate the boundary of the visual field.

Results obtained using Visual Field Analyzers are used to find pathologies that affect peripheral vision, like retinal detachment. These results can also help detect pathologies in which peripheral and central vision are affected.

In some cases, Visual Field & Visual Field Analyzers may also be used to determine disability classifications, select eligible military personnel, narrow down a field of job applicants, screen students or community members, or assess visual competence.

Visual Field Analyzers may use kinetic or static Visual Field Analyzers.

Kinetic Visual Field Analyzers are mobile targets, but they have a fixed luminosity. The examining physician will move the mobile stimulus to determine the visual field. The test starts with a single light, which the examiner moves from the patient’s periphery toward a designated location, until the patient can detect the light.

Static Visual Field Analyzers are essentially fixed targets. The light will be stationed at a specific location. The examiner will brighten the light if the patient can’t see it. This will continue until the patient notices the light, and the procedure will be repeated at several different locations until the visual field is defined.

Below, you’ll find several industry-leading Visual Field Analyzers that make identifying the visual field a seamless process.
