Visual Field Testing

It is an eye examination that can detect dysfunction in central and peripheral vision which may be caused by various medical conditions such as glaucoma, stroke, brain tumours or other neurological deficits. Visual field testing can be performed clinically by keeping the subject's gaze fixed while presenting objects at various places within their visual field. Simple manual equipment can be used such as in the tangent screen test or the Amsler grid. When dedicated machinery is used it is called a perimeter. The exam may be performed by a technician in one of several ways. The test may be performed by a technician directly, with the assistance of a machine, or completely by an automated machine. Machine based tests aid diagnostics by allowing a detailed printout of the patient's visual field.

Common problems of the visual field include scotoma, hemianopia, homonymous hemianopsia and bi temporal hemianopia.

: Cataract is a clouding of the lens in the eye leading to a decrease in vision. It can affect one or both eyes. Often it develops slowly. Symptoms may include faded colors, blurry vision, halos around light, trouble with bright lights, and trouble seeing at night.[1] This may result in trouble driving, reading, or recognizing faces.[2] Poor vision may also result in an increased risk of falling and depression. Age-Related Macular Degeneration is common cause loss of sharp vision in one or both eyes in people over the age of 60. Symptoms for AMD are Fuzzy or blurry areas, Distorted & wavy edges, Faded color Vision, that varies from day to day. Although AMD can cause vision loss that ranges from mild to severe, it rarely causes total blindness.
