Certified Ophthalmic Medical Technologist (COMT) Practice Exam

What is the typical distance between the examiner and the patient during a confrontation visual field test?

1. One foot

2. Two feet

3. Three feet

4. Four feet

The correct answer is: Two feet

During a confrontation visual field test, the typical distance between the examiner and the patient is approximately two feet. This distance allows the examiner to effectively evaluate the patient's peripheral vision while ensuring both the examiner and the patient can clearly see and interact with each other. At this range, the examiner can present visual stimuli—such as fingers or lights—in a manner that's easily visible for the patient while still maintaining a close enough proximity to monitor cues and responses accurately. Being too far can make it difficult for the patient to see the stimuli, particularly in the peripheral fields, leading to potential inaccuracies in the test results. Thus, the two-foot distance is ideal for conducting this important screening test effectively.
