Certified Ophthalmic Medical Technologist (COMT) Practice Exam

Which test is designed to assess disability due to loss of visual field, commonly used for Secretary of State/Motor Vehicle forms?

1. Esterman visual field test

2. Humphrey 24-2 test

3. Octopus visual field test

4. Goldmann perimetry

The correct answer is: Esterman visual field test

The Esterman visual field test is particularly designed to assess visual field disability in patients, making it relevant for evaluating candidates who must report their visual status for Secretary of State or Motor Vehicle approval. It provides a comprehensive measurement of peripheral vision, which is crucial for determining one's ability to operate a vehicle safely. This test is structured to produce results that can easily demonstrate a person's visual capabilities, aligning with the specific requirements of motor vehicle regulations regarding driving eligibility. It focuses on both monocular and binocular visual field as seen in activities of daily living, thus effectively measuring the extent of visual field loss that can affect driving performance. In contrast, while the other options such as the Humphrey 24-2 test, Octopus visual field test, and Goldmann perimetry also measure visual fields, they do not specifically cater to the regulatory requirements associated with driving assessments in the same direct and functional manner as the Esterman test. Each of these tests serves other purposes within clinical settings but may not convey the same succinct and relevant information needed for state motor vehicle evaluations.
