Detailed explanation-1: -All four quadrants (upper and lower, temporal and nasal) should be tested. Stationary targets are more precise because they present a finer stimulus to the retina and are less easily identifiable relative to a moving target.
Detailed explanation-2: -Confrontation visual field testing involves having the patient looking directly at your eye or nose and testing each quadrant in the patient’s visual field by having them count the number of fingers that you are showing. This is a test of one eye at a time.
Detailed explanation-3: -Another less sensitive but highly specific test is known as the confrontational visual field exam1. This is a simple and quick way to assess the peripheral vision of the patient without the use of expensive specialized equipment.
