| Abstract |
|
The authors performed Titmus and TNO stereopsis tests in the group of children amblyopes aged from 3 to 11 year old in order to evaluate clinical usefulness of stereopsis in amblyopia and preschool vision screening. 36(72%) and 42(84%) amblyopes could not pass the Titmus 100 see and TNO 120 see each and if 6 amblyopes who had 0.8 or better vision were excluded, the sensitivity were 82%(36/44) and 95%(42/44). Each visions of amblyopic eyes gave the main influence to decide stereoacuity in the Titmus test(correlation coefficient=0.69) and all of the amblyopes who had 3 or more interocular acuity differences could not pass the TNO 120 sec. As a result Titmus test had too low sensitivity to use as the screening test but it was useful to evaluate the vision of amblyopiceye. TNO was sensitive to interocular acuity differences and the authors thought that TNO 120 see can be used in the screening. |
