Interventions for visual field defects after stroke: a systematic review.

After a stroke, many patients lose parts of their visual field. It is common to lose half of the visual field (right or left) on both eyes. Interventions that have been tried include regaining (parts of) the visual field (restitution), compensate for the visual field defect by changing behavior and activities (compensation), or finding replacements for the visual defect by using aids (substitution). We have included 10 studies (6 on compensation, 2 on substitution, and 2 on restitution).  Compensation strategies (training on eye scanning, reading, and exploration of the visual field) may improve the visual field, reading, and the ability to perform actitivities of daily living (ADL)  The documentation for substitutional‐ and restitutional strategies is of very low quality and the effects are uncertain We have not found studies that deal with assessment and screening interventions.
