Assessments Of Confrontation Tests On Eye Examinations?
I wanted to ask about a confrontation test to assess the field of view of the eyes. How do we determine the score for the confrontation test? Is it mistaken or still using campemeter? If you don’t have a measuring device, is there another way? thank you
Good morning, thanks for asking at HealthReplies.com. The confrontation test is one of the tests performed in an eye examination with the aim of finding out whether the patient's field of view is normal. The field of view is the entire area that can be seen by the eye, which consists of the central view in the middle, and the peripheral view which is the part that is visible even though we do not move the eyeball, even though it is not as focused as the central view.
One of the diseases most commonly recognized for reducing peripheral vision is glaucoma. People with glaucoma usually don't notice their peripheral vision is reduced and often complain of tripping or bumping into something while walking.
How to do a confrontation test is as follows. The patient and examiner are seated opposite to a distance of about 60 cm, then both the patient and examiner cover their eyes either with the hand or other covering on the side. So suppose the patient closes his right eye, because the examiner sits opposite, so the examiner closes the examiner's left eye. The test is performed by the examiner using a specific focus point, either a finger or a pen, then stretching out the hand that does not close the eye and pulling it in or toward the body several times. First with the position above, one in the middle and below. Checks may be done more frequently to get more accurate results. Then proceed with the other eye.
Regarding your question, there is no need to use a campimeter or visual field aid to do this test, you can just guess. However, for other purposes such as determining the progression or progress of recovery, or comparing the severity, campymetry may be needed in order to get an accurate degree comparison. Our advice is to consult again about your questions to the ophthalmologist to avoid misunderstanding. So, hopefully this is useful.
