Goldmann kinetic perimetry differs from static automated perimetry (Humphrey) primarily in that Goldmann perimetry:

• A Tests only the central 30 degrees of visual field
• B Generates a mean deviation (MD) and pattern standard deviation (PSD) for statistical analysis
• C Uses stimuli of varying size and luminance moved from non-seeing to seeing areas to plot isopters ✓
• D Employs a staircase threshold strategy at fixed stimulus locations

Explanation

Goldmann kinetic perimetry uses targets of defined size (I–V) and luminance that are moved from the periphery inward until the patient first sees them, plotting iso-sensitivity contour lines called isopters. This maps the entire visual field including far periphery and is excellent for neurological defects and low-vision patients. Humphrey static automated perimetry tests fixed locations with static stimuli of varying luminance using staircase threshold strategies and generates statistical indices (MD, PSD) but is limited to the central 30 degrees in standard programmes. Kinetic perimetry does not generate MD/PSD.
