摘　　要：背景:立体视是了解双眼单视功能是否完善的一个重要指标,它在斜视、弱视、屈光不正等眼病的诊断及疗效评价方面有重要意义。目的:了解海口市3～6岁儿童斜视患病率及立体视觉的发育情况,以便对斜视及立体视异常的及时防治提供客观数据。设计:随机、整群抽样调查。单位:海口市人民医院眼科。对象:选择2000-06/2002-04海口市中心区及市郊随机抽取的25所幼儿园儿童8326人,年龄3～6岁。方法:对海口市3～6岁8326名儿童进行远视力、眼位、近立体视等检查,双眼视力低于1.0或眼位异常者行阿托品散瞳验光。①4～6岁查国际标准视力表或对数视力表,3岁查条栅或图形视力表,经换算统一以小数记录。②用角膜映光法及遮盖法查眼位。③应用中国科学院生物物理研究所立体视力检测卡查立体视锐度(≤60s为正常,≥100s为异常)。各检查项目医生固定。主要观察指标:①各年龄组受试者眼位及立体视检查结果。②斜视儿童验光结果。③受试者视力与立体视锐度的关系。④各年龄组儿童的立体视锐度。⑤影响立体视的可能病因。结果:按实际处理分析。8326人进入视力及眼位检查的结果分析,7664人进入立体视检查的结果分析,662人未能表达立体视检查项目而退出。①各年龄组受试者眼位及立体视检查结果:斜视者165人,占2.0%;首次发现斜视占斜视患儿的89.7%;立体视检查≥100s者2106人,占27.5%。②斜视儿童验光结果:内斜视患者中93.5%发生于远视眼,外斜视及垂直性斜视患者中远视眼及近视眼构成比无明显差别。③受试者视力与立体视锐度的关系:正常者立体视锐度正常率为75.5%。随着视力的下降,立体视锐度下降(P<0.05或0.01)。④各年龄组儿童的立体视锐度:随着年龄增加,立体视锐度正常者也呈增加趋势。⑤影响立体视的可能病因:以斜视性弱视影响最大。结论:①调查结BACKGROUND： The evaluation of 8tereoacuity can provide an unambiguous assessment of haplopia. It is valuable in assessing the diagnostic accuracy and the therapeutic effect in strabismus, amblyopia and ametropia. OBJECTIVE： This investigation was designed to evaluate the stereoptic development and the occurrence rate of strabismus in 3-6 years old children, and so that to provide objective data for prevention and treatment of strabismus and steropsis. DESIGN： It was a randomized sampling investigation. SETTING： Department of 0phthalmology,Haikou People＇s Hospital. PARTICIPANTS： Totally 8326 children in 25 urban and suburban kindergartens, with an age of 3-6 years old, were selected randomly in Haikou city from June 2000 to April 2002. METHODS： 8 326 3-6 years old children in Haikou city underwent vision examinations on hyperopia, eye position and the myopia. Those having eyesight lower than 1.0D or abnormal eye position received atropine drops to dilate the pupil of the eye for optometry. ① 4-6 years old children were examined using standard visual chart and logMAR chart （logarithm of the minimum angle of resolution chart）, 3 years old children were examined using broken wheel acuity cards or symbols chart. The results of the exminations were conversed and recorded in form of decimal fraction uniformly. ② The corneal reflection and the cover test procedure were used for the position of gaze. ③ Stereoacuity were examined using the stereoptic visual testing cards （made by the Institute of Biophysics, Chinese Academy of Sciences）. Stereoacuity were defined as normal when the test value was ≤ 60 s and were defined as abnormal when it was ≥ 100 s. Each examination was performed by same selected physicians. MAIN OUTCOME MEASURES： The main outcome measurements ineluded ① results of eye position examination and stereoptic examination in children in all age brackets, ② results of optometry in children with strabismus, ③ The relation between eyesight and stereopsis in partieipants,�
