b. inferior, nasal, temporal, superior, and oblique angles
c. nasal and temporal angles
d. oblique, inferior, and superior angles

Answer 1

B
The confrontation technique is used to examine visual fields and is a gross measure of peripheral vision. It compares the person's peripheral vision with the examiner, assuming the examiner's peripheral vision is normal. The visual field of each eye is divided into 4 quadrants, and a stimulus is presented in each quadrant. The examiner positions herself 2 to 3 feet away at eye level with the patient. Direct the patient to cover one eye, and to look straight at you with the other eye. Cover your eye that is opposite the person's covered eye. Hold a pencil or your flicking finger as a target midline between you and the patient. Slowly advance the object from the periphery into both your field of vision and the patient's field of vision from nasal, temporal, superior, inferior, and oblique angles. Ask the patient to say "now" when your finger is seen moving into the field of vision. Normal results are 60??nasally, 90??temporally, 50??superiorly, and 70??inferiorly.
