متن کاملA Novel Computerized Visual Acuity Test for Children
PURPOSE To investigate the efficacy of a computerized visual acuity test, the SNU visual acuity test for children. METHODS Fifty-six children, ranging from 1 to 5 years of age, were included. In a dark room, children gazed at and followed a circular dot with 50% contrast moving at a fixed velocity of 10 pixels/sec on a computer monitor.

The normal visual acuity is found to correspond to an average minimum visual angle of one minute. Thus with relatively small angles one may say that the visual acuity is inversely proportional to the space which sep...
متن کاملThe 'mirror test' for estimating visual acuity in infants.
OBJECTIVE The authors aimed to investigate the association between the distance at which infants fixate their own reflections and visual acuity card testing, and to determine whether this could form the basis of a new clinical test of visual function in infants. METHODS 78 healthy infants under 9 months of age (range 1-266 days, mean 56.5+/-64SD) were recruited and held close to a mirror such...
