Volume 46, 1996, p. 99–105 Acceptance/Use of the Teller Acuity Card Procedure in the Clinic (Abstract) The Teller Acuity Card (TAC) procedure is a simple, subjective method of assessing visual acuity in infants and children unable to be tested with standard clinical techniques. The TAC procedure was incorporated into the national Multicenter Trial of Cryotherapy for Retinopathy of Prematurity (CRYO-ROP) to assess grating acuity between 1 and 5 1/2 years of age in a group of children with birth weights less than 1251 g. To determine if the TAC procedure has become a routine method of assessing vision in the clinical settings of the multicenter study, a survey addressing testing procedures, tester qualifications, and patient characteristics was sent to each principal investigator at each of the 23 study centers. Twenty-two centers responded to the survey, and seventeen (77%) of these are now using the TAC procedure for non-study patients. |
