目的评价侧视症儿童立体视觉的变化,探讨儿童侧视症的成因。方法记录侧视症儿童主导眼及头位偏斜情况,观察其面向正前方、面转向主导眼侧和面转向非主导眼侧注视时的立体视锐度,并与正常儿童比较。结果主导眼与侧视症头位偏斜方向无关。侧视症儿童面向正前方及面转向主导眼侧和非主导眼侧注视时立体视锐度与正常儿童相比差异无统计学意义。侧视症儿童及正常儿童面转向一侧注视时较向正前方注视时立体视锐度增大,差异有统计学意义。结论侧视症儿童立体视功能正常。侧视症产生原因需进一步探讨。
Objective To evaluate the changes of stereopsis in children with lateral visual acuity (STI) and explore the causes of SOP in children. Methods The prevalence of dominant and ocular tilt in children with STDs was recorded and the stereoacuity of the children with STDs was recorded and compared with normal children. The results of the dominant eye and the head tilt position has nothing to do. There was no significant difference in stereoacuity of stereopsis children when compared with that of normal children when the children with lateral vision turned to face the front and the face turned to the dominant and non-dominant eyes. The visual acuity of stereopsis increased when the children with visual acuity and the normal children turned to one side when looking at the anterior face. The difference was statistically significant. Conclusion The children with stereopsis have normal stereopsis. The cause of lateral vision needs to be further explored.
