53 subjects with normal binocular single vision and normal stereoacuity (SA) were performed the Titmus Stereo Test while degrading the visual acuity (VA) monocularly and binocularly with graded hazy films. The results showed that SA impairment with monocular decrement was more than with binocular symmetrical decrement at each VA level. The authors inferred that imbalance of VA between the two eyes in infants and children was harmful to the development of binocular vision, and that partial occlusion therapy would be more favorable for the binocular visual development of amblyopic children. Also, it was suggested to include SA in the criteria for cure of amblyopia.
对53名具有正常双眼单视和正常立体视锐度（SA）的受试者，使用分级模糊片单眼和双眼降低视力（VA）的同时进行Titmus立体视测试。结果显示，在每个视力水平下，单眼视力下降导致的立体视锐度损害比双眼对称下降更严重。作者推断，婴幼儿双眼视力不平衡对双眼视觉发育有害，部分遮盖疗法对弱视儿童的双眼视觉发育更有利。此外，建议将立体视锐度纳入弱视治愈标准。
