Objective To determine the effect of decreased visual acuity due to cataract on tests of cognitive function in the elderly. Method Patients at a precataract surgery assessment clinic were screened to exclude cognitive impairment. The CAMCOG was completed by 42 subjects, and the visual acuity for each eye assessed. Results There was a significant correlation between visual acuity and the CAMCOG score, which was abolished when simple modifications were made to the CAMCOG. Although 5 subjects scored below the cut‐off point, 3 with worse visual acuity scored within the cut‐off. Conclusions Visual impairment has a significant effect on the scoring of the CAMCOG. However, the effect may not only be due to decreased visual acuity but also to other factors such as contrast sensitivity, which may be affected by cataract. Copyright © 2000 John Wiley & Sons, Ltd.
