confrontational visual field testing /kon′frəntā″shənəl/ [L, con + frons, forehead] , a method of assessing a patient’s visual field by moving an object into the periphery of each of the visual quadrants. The test is conducted while one eye is covered and the vision of the other is fixed on a point straight ahead. The patient reports when the moving object, which may be the examiner’s finger, is first detected at the edge of the visual field.
