How to test for homonymous and bitemporal visual field defects by confrontation... without getting your fingers and arms in a twist! This is the third of a series of instructional videos aimed at neurology students and trainees to demonstrate how to perform an efficient clinical neurological examination by testing the patient's eyes.
Although it is possible to test for ring scotomas (found in retinal and optic nerve diseases), and enlarged blind spots and irregular field defects (found in optic nerve disease) using confrontation it is very difficult, and I would recommend that you use an automated visual fields machine for this. By contrast, it is quick and easy to screen for homonymous and bitemporal defects, and you should incorporate these 2 examination techniques into your routine neurology examination, be it in the emergency room, general practice, or in a scheduled care setting.
