Which common instruments are used for static threshold perimetry?

1. Humphrey Field Analyzer

2. Goldmann perimeter

3. Both A and B

4. Tangent screen

The correct answer is: Both A and B

Static threshold perimetry is a critical test in assessing visual field sensitivity and is commonly utilized in diagnosing and monitoring various ocular conditions. The instruments used in this type of perimetry generate a detailed map of the visual field by presenting light stimuli at specific locations and measuring the patient's ability to detect them. The Humphrey Field Analyzer is widely recognized for its ability to perform automated static perimetry. It provides precise data on visual field defects and is frequently used in clinical practices due to its efficiency and accuracy. Similarly, the Goldmann perimeter is designed for both kinetic and static perimetry. In the context of static threshold perimetry, it allows for the testing of visual sensitivity at fixed points, making it invaluable in a detailed assessment of the visual field. Both the Humphrey Field Analyzer and the Goldmann perimeter are essential tools for performing static threshold perimetry, as they provide reliable and comprehensive visual field assessments. This makes the correct choice for the question both of these instruments, confirming the appropriateness of the answer that includes them both. The Tangent screen, while also a form of perimetry, does not typically perform static threshold testing in the same refined way as the other two; hence it is not included as a common
