The Vision Field Investigation: Method to perform the exam and analyze the results

Visual Field Test -Perimetry -Test sponsored the field of vision investigation, is an investigation aimed at verifying the integrity of the vision of each eye separately, including the central and side vision. When is the examination performed? A vision examination gives us information about different patterns of vision loss. Class is exposed to danger that people with vision problems are the category that does a vision field investigation. Diseases related to investigation are one of the most important diseases associated with the following investigation: Cataract. Macular degeneration. Bleeding in the retina. The retina separation. Stroke. How to perform the examination is performed by the vision examination by distinguishing optical points by a device called the perimeter, which summarizes the results within a computer, this computer gives a general image of the patient’s vision field, if there are areas, the patient may distinguish the optical points in it due to a problem with the vision that the computer is a blind place. Steps to conduct the investigation into the following steps of this investigation: The patient sits in front of a computer -like device and focuses on a central point. The computer relieves different points on the screen in front of the patient to examine the sensitivity of light in different areas on the field of vision. The patient is asked to push a button when he sees the points on the screen. These points are slowly weaker during the investigation until the patient reaches a stage where he cannot see these points at all. In this way, the device can determine the minimum intensity of the light that the patient in each area can determine in the field of vision. The field of vision is performed separately for each eye, and it is not necessary to prepare before doing a vision field examination, and the patient who places glasses should bring it to the examination. General warnings are not expected. During pregnancy: There are no special recommendations. Breastfeeding: There are no special recommendations. Children and babies have no special recommendations.
