Abstract

A method and an apparatus for capturing a visual field of a person having a scotoma, in particular a central scotoma, are disclosed. The method includes continuously capturing the eye alignment of the person with a capturing unit, sampling the visual field of the person point-by-point to determine points suitable and not suitable for sight in the visual field of the person, finding the scotoma as a region with a multiplicity of points not suitable for sight, calculating an outer boundary line of the scotoma, calculating an outer enveloping curve, which surrounds the outer boundary line of the scotoma at a predetermined distance, and displaying the outer enveloping curve on a display unit. The enveloping curve is perceivable by the person on the display unit as a frame of the scotoma.
