What is the test in the field of view?

The field of view of the field of view measures the entire range of man's vision. This includes both central and peripheral or side vision. These tests map individual eye fields. Testing of the field of vision requires the patient's full cooperation because they must understand the test to be performed and participate in the whole test so that the patient can thoroughly understand his condition.

Eye test that is not as thorough as the field of vision does not have to measure peripheral vision. Peripheral vision is a complete horizontal and vertical range of what one sees. Commonly called secondary vision, it is a part of the eyes that the patient does not see directly, but from the corners of his eyes.

The point of view of the field of view is to detect blind places that may indicate eye diseases. Eye disease includes damage to optical nerves, optical neuropathy, retinal disease, decrease in eye, toxic exposure and damage to the inner lid of the eye caused by the light exposure. The eye field test can also detect abnormalities in the brain that cause strokes or a containerRy. These abnormalities affect not only the field of vision, but the placement of a stroke or tumor is often determined by the size, shape and location of the eye problem or defect.

The

field of vision is performed by a patient covering one eye and looking forward directly at the target object. Central vision and peripheral vision are tested individually. The doctor tests the patient's central vision by focusing on part of his face, such as an eye or ear. To test peripheral vision, the patient also fixes one object, but is asked to describe what can be seen from the corners of his eyes.

Visual field testing types include automated perimetry, frequency double perimetry, electroeetinogram and confrontational. Automated perimeters should remedy the patient on the light source, so the reaction to the presence of objects in different areas of the fields can be tested. Frequency double perimetry involves usingThe colorful vertical strips to flicker at high frequencies. If the patient does not see the bars, the optical nerve damage may be present.

The electroetinogram measures how the patient reacts to flashing stimuli, and the electrode can detect the degree of sensitivity of the retina. Too sensitive retina can be a sign of eye disease. The last main type of visual field test is the confrontational test. This tests peripheral vision by moving the object around the patient's peripheral vision to test the response speed.
