Role of prism relocation in improving visual performance of patients with macular dysfunction.

Patients with macular dysfunction were given spectacle lenses with prism and a control group of similar patients were assessed without prism. About 60% of those without prisms learned to improve acuity by eccentric viewing. Over 90% of those fitted with prisms showed an improvement in acuity and performed better on locomotion tests.
