HIGH-PASS RESOLUTION PERIMETRY - A CLINICAL REVIEW

Review of all available reports comparing high-pass resolution perimet ry (HRP) and conventional perimetry in normals and in subjects with di fferent visual disorders reveals closely comparable aspects of sensiti vity, specificity, and reliability. HRP shows important advantages con cerning variability, test duration, and subject preferences. Drawbacks seem largely limited to somewhat loose renditions of visual field def ects of small area and large depth. Otherwise HRP's novel format of gr aphic result presentation may be better suited to visual evaluation th an conventional gray-scale maps with their lumping of thresholds and e xtensive interpolations. Several examples are provided of visual field defects due to various lesions throughout the visual system.
