Visual Field Limitation in the Patient with Dementia of the Alzheimer's Type

Abstract

This paper investigates the existence of a visual field limitation and its effect on the advanced Alzheimer''s patient. The data presented was obtained by testing 12 Alzheimer''s and 12 control patients. The control patients were demented from causes secondary to reasons other than Alzheimer''s disease. The results indicated that patients demented due to Alzheimer''s have visual field losses significantly greater than other demented patients. This significant visual loss is of importance in assisting in differential diagnosis, performing patient cares, and planning patient environments.
