The methods of visual field examination are contrast method and visual field meter method. 1.Contrast method: The examiner and the patient sit opposite each other, the eye position is equal, 1 m apart. examine the right eye, so that the patient’s right eye and the examiner’s left eye, respectively, cover the other eye, the examiner will be placed at equal distance from the two, in all directions from the periphery to the center of the slow movement, the visual field seen by the physician and the patient for comparison. This method is simple and easy to use, and can be roughly checked for obvious peripheral visual field narrowing. 2, visual field meter method: (1) solitary visual field meter: curved visual field meter is used to check the peripheral visual field beyond 30 ° from the point of gaze. Let the patient’s chin fixed in the bracket, the examined eye and visual field meter central gaze point in the same horizontal line, and fixation on the central gaze point, cover the other eye, with different colors of the visual field meter along the arc of the plate from the periphery to the center, the patient can see the position of the visual marker and the visual marker disappeared and reappeared. (2) Automatic visual field meter: It is used to examine the central visual field within 30° from the point of gaze, and is suitable for finding visual field defects in smaller centers. The automatic visual field meter can automatically follow the procedure to determine the light threshold at each site of the visual field with different brightness of light stimulation and record it, and calculate the total amount of visual field loss and the depth and range of visual field defects, thus increasing the accuracy and sensitivity of visual field examination. In summary, the visual field examination methods are contrast method and visual field meter method, contrast method can be simple rough measurement of the peripheral visual field, visual field meter can be more accurate examination of the peripheral or central visual field.
