Visual acuity was estimated in each eye and binocularly for 16 communicative nursing home residents using the Teller Acuity Card (TAC) Procedure. TAC acuities were compared to Snellen visual acuities. Pearson correlations between visual acuity and TAC acuity were: 0.72 for the right eye, 0.84 for the left eye, and 0.72 for the binocular viewing condition (P < 0.01). Testing-retest reliabilities of TAC acuity estimates and inter-observer reliability of binocular TAC acuity were high. These data are encouraging, and suggest that the TAC procedure, previously employed only in pediatric ophthalmology, provides a reasonable estimate of visual acuity in the aged. The authors suggest that this assessment be incorporated into the health care delivery system of nursing home residents.
