12

In Goldman perimetry, it is standard practice to examine 12 meridians. This method allows for a comprehensive assessment of the visual fields by systematically testing various angles around the visual axis, which helps in detecting defects that may indicate underlying ocular or neurological conditions. The 12 meridians typically cover both the horizontal and vertical axes, as well as additional angles between them, ensuring that the visual field is thoroughly mapped.

While other numbers of meridians might be employed in different types of perimetry or specific clinical scenarios, the established practice in Goldmann perimetry focuses on the 12 meridians to provide a complete evaluation of the patient's visual capability across the visual field.
