Which technique is often used for initial visual field screening?

Confrontation Testing is the correct choice for initial visual field screening because it is a simple and quick method that can be performed in a basic clinical setting without the need for specialized equipment. During this technique, the examiner positions themselves in front of the patient and asks them to look at their eyes while covering one eye. The examiner then presents visual stimuli (such as moving fingers) in each of the patient's peripheral visual fields. This allows the examiner to gauge the patient's overall visual field and identify any gross abnormalities that may need further investigation.

This method is particularly useful as an initial assessment since it requires minimal setup and can be conducted in various settings, making it accessible for practitioners. It's an efficient way to detect significant visual field loss before more advanced and precise testing is warranted.

In contrast, Threshold Testing, Kinetic Testing, and Static Automated Perimetry are more detailed methods that assess visual fields with greater precision, often requiring specialized equipment and longer time commitments. They are typically utilized after an initial screening indicates potential issues, as they provide more comprehensive data on a patient's visual field status.
