3 种立体视检查法在学龄前儿童眼保健检查中的应用比较简

目的 比较Titmus、立体视觉检测板及立体视觉检查图在学龄前儿童眼保健检查中的立体视锐度值分布及完成情况。方法 对一组身体健康，智力正常，双眼视力、眼位、眼活动度、眼前段、眼底均正常的3～＜7岁儿童共428人，分4个年龄段，3～〈4岁、4～〈5岁、5～〈6岁及6～〈7岁，在相同环境中分别做3种立体视锐度测定。结果 立体视锐度值随着年龄的增加而提高，Titmus、立体视觉检测板：各年龄组差异有统计学意义（χ2=114.62，P〈0.01；χ2=85.62，P〈0.01）。立体视觉检查图：各年龄组差异无统计学意义（χ2=6.33，P〉0.05）。完成人数：立体视觉检测板＞Titmus＞立体视觉检查图，但各年龄组差异无统计学意义（χ2=9.94，P〉0.05）。结论 不同年龄立体视锐度阈值有差异，随着年龄的增长而提高，不同检查手段所得立体视锐度阈值亦不一致。Titmus法及立体视觉检测板法适合儿童筛查；Titmus与立体视觉检查图相结合可取得更为精确的结果。

The application comparison of three kinds of stereopsis inspection methods in preschool children eye health check

The application comparison of three kinds of stereopsis inspection methods in preschool children eye health check
Objective To compare the difference and stereopsis sharpness value distribution of Titmus, stereo vision testing board and stereo vision inspection graph in the eye health check of preschool children. Methods Four hundred and twenty eight children aged 3～7 years old with normal intelligence, binocular vision, eye activity, anterior segment and fundus were divided into four age groups（3～〈4,4～〈5,5～〈6 and 6～〈7 years old）. Three kinds of three-dimensional visual sharpness were measured in the same environment respectively. Results Stereoscopic sharpness value increased with the age.There was statistically significant difference of Titmus and stereo vision testing board among all age groups （χ2 = 114.62, P〈 0.01;χ2 = 85.62, P〈0.01）. There was no statistically significant difference among all age groups （χ2 = 6.33, P〉0.05） of stereo vision inspection graph. The complete number of stereo vision testing board was more than that of Titmus, and the complete number of Titmus was more than that of stereo vision inspection graph.There was no statistically significance among all age groups. （χ2 = 9.94, P〉 0.05）. Conclusions There are differences of stereoscopic sharpness value threshold for different age. Stereoscopic sharpness value is increasing with age. The threshold value is different as different inspection method is used. Titmus method and stereo vision testing board are suitable for screening in children. Titmus combined with stereo vision inspection graph can obtain more accurate results.
