The most commonly used perimetry screening test that does not require formal instruments is confrontation visual fields. This method is often utilized in clinical settings because it can be performed quickly and without the need for specialized equipment. The technique involves the examiner and patient sitting facing each other, where the examiner presents various visual targets in the periphery of the patient's visual field. The patient is asked to indicate when they see the target, allowing the examiner to assess the patient's peripheral vision.

Confrontation visual fields are particularly useful as a preliminary examination tool, especially in settings where access to advanced perimetry equipment is limited. It provides immediate feedback regarding possible visual field defects, which can then prompt further testing if necessary. This approach is practical for initial assessments and can help identify issues such as glaucoma or neurological deficits.

Other forms of perimetry, while important, typically require formal instruments or specific setups, which makes confrontation visual fields a more accessible choice for many clinics and practices.
