What is a defect of the field of view?
If a person is not blind, it should be able to see a certain amount of their surroundings. There are standards regarding this ability that are considered normal. These standards are referred to as a field of view or field of view. When a person's ability to see its surroundings does not meet the standards, it can diagnose a defect from the visual field. Such a condition could be caused by glaucoma, macular disease or aneurysm.
In order to understand what is a defect of the field of vision, it may be useful to think about the sight, as can be seen through the telescope. The two circular areas displayed can be considered as a field of view. The human display field should include the ability to see a certain amount vertically and horizontally. In this case, the defect of the field vision could be diagnosed if any part of the field of view is blocked. A defect
in this sense means a ability that is partly defective. Blindness is not considered to be a defect in vision of the field. This is because blindness is supposed to tend to completely inability. It is possible for a person toShe had a defect of the field of vision without realizing it. This may cause a person to have accidents that can be considered as clumsy errors.
The causes of the field of vision may vary significantly. Certain causes are often associated with different types of defects. For example, a peripheral field of vision could be caused by glaucoma or the retina department. If there is a defect of the central field, it could be caused by macular holes or conical dystrophy. A lesion that can occur anywhere is a visual way of man, is a common cause of various such defects.
If a person is looking for medical assistance for such a situation, there is some information that is likely to be asked to provide. The ophthalmologist is likely to want to know when and how the problem arose. Patients are also generally asked to describe what they experience. This may include the degree or the way the objects look deformed and whether PThe robble occurs at both eyes.
There are several methods to test, whether a person has a defect from a visual field. Direct confrontation concerns the basic testing methods that include the introduction of objects, such as fingers or light into a human field of view, and let it feed on what they see. However, there are more specialized tests such as electrolytinography. This testing method uses electrodes to assess the activity in the retina.
