Guidelines/Instructions
The examiner should click the START TEST button on the examiner’s screen. The examiner will present one set of practice visual acuity trials (four letters) at size 20/400. a. If the child gets three or more correct, continue to visual acuity testing. b. If the child misses two or more of four, review the laminated ‘pointing chart’ and ask him/her to identify (either orally or by pointing) the four letters HOTV. If all are done correctly, see step c below. If child cannot correctly identify the optotypes on the HOTV set, repeat the training above one more time. c. Proceed to a second practice trial set. If three or more of four are done correctly, proceed to live visual acuity testing. If not,repeat (third practice trial set). If three or more are correct on the third practice trial, begin visual acuity testing. If two or more are incorrect, stop the test since this is the third practice trial (step d below). d. Practice trials should be limited to a total of three sets. If, after three trials, the criterion of three or more of four correct is not achieved, then stop the test. c. Proceed to a second practice trial set. If three or more of four are done correctly, proceed to live visual acuity testing. If not, repeat (third practice trial set). If three or more are correct on the third practice trial, begin visual acuity testing. If two or more are incorrect, stop the test since this is the third practice trial (step d below). d. Practice trials should be limited to a total of three sets. If, after three trials, the criterion of three or more of four correct is not achieved, then stop the test.
