Assessing Field Defects of the Low‐Vision Patient

Key Points

To determine effective methods for assessing field losses in low-vision patients when traditional mapping is not feasible.
Described various devices and techniques for mapping visual fields.
Focus on simplified techniques suitable for patients with fatigue or debility.
Emphasis on qualitative analysis of field loss.
Simplified techniques effectively assessed field losses even in challenging patient conditions.
Clinicians reported improved ability to evaluate field defects with these methods.

Abstract

Abstract Field losses are of particular significance to the low‐vision patient, so it is incumbent upon the low‐vision clinician to determine the degree, location, and extent of this field loss. Optometrists prefer to map the fields carefully for quantitative analysis, but if fatigue or debility prevent this a simplified technique is required. Devices and techniques are described which are shown to be effective.
