弱视治愈行斜视矫正术后视力追踪观察

目的了解斜视性弱视及斜视性屈光参差性弱视患者在弱视治愈,行斜视矫正术后,弱视眼视力的变化.方法对1992～1997年在我院弱视治愈后行斜视手术矫正患者103例进行视力追踪观察.结果弱视治愈后行斜视手术后原弱视眼有50.49%存在不同程度视力减退,并且与开始治疗时弱视程度有关,即弱视开始治疗时的视力越低越易出现视力减退.结论弱视治愈行斜视术后的弱视眼,应密切监护,直到视力、眼位均巩固在正常范围为止.     

远方视力训练法治疗斜视性弱视临床研究

目的:总结远方视力训练法治疗单眼斜视性弱视的疗效。方法:对240例患病儿童进行前瞻性研究,随机分组,与传统遮盖疗法进行对比,随访3mo。结果:远方视力训练法促进弱视眼视力提高显著优于传统遮盖法。与传统遮盖疗法在治愈率(18%)、显效率(60%)及有效率(93%)方面对比均有统计学意义。结论:远方视力训练法是治疗单眼斜视性弱视行之有效的新方法。     

山东滕州市农村小学生弱视斜视及立体视锐度调查

目的 调查滕州市农村小学生的视力、立体视锐度及弱视和斜视的患病情况,并对Titmus立体视图检查法、视力检查法、Titmus立体视图联合视力检查法三种弱视筛选试验进行评价.方法 应用随机整群抽样调查方法,共抽取滕州市8所农村小学,共有小学生2742人,年龄5～14岁,平均(9.3±2.3)岁.进行Titmus立体视图、裸眼视力、眼位及眼球运动检查,对任一眼裸眼视力<1.0者进行视网膜检影验光.结果 (1)小学生视力低常率为13.83%,从7岁至13岁视力低常率呈逐渐上升趋势;视力低常的首位原因为屈光不正,弱视,其中近视占79.67%(486眼/610眼);(2)弱视患病率为1.50%.97.5%(39/40)的弱视患儿为首次被筛查出来;斜视患病率为1.72%;(3)非弱视/斜视儿童的立体视锐度5岁年龄组为60″,6岁年龄组为50″,7岁及以上年龄组均为40″;弱视患者中立体视锐度异常者占77.5%(31140),斜视患者中立体视锐度异常者占28.3%(13/46);(4)Titmus立体视图联合视力检查法筛选弱视的特异度(99.47%)及粗一致性(99.06%)最高,误诊率(0.53%)最低;其次为Titmus立体视图检查法(特异度为97.98%;粗一致性为97.59%;误诊率为2.02%);视力检查法的特异度(87.47%)及粗一致性(87.66%)最低,误诊率(12.53%)最高.结论 滕州市农村小学生视力低下的首位原因为近视;弱视和斜视是影响立体视觉发育的主要因素;Titmus立体视图联合视力检查法可提高学龄儿童弱视筛选的效率.     

山东滕州市农村小学生弱视斜视及立体视锐度调查

Objective To investigate the visual acuity, stereoacuity and the prevalence of amblyopia and strabismus ofprimazy school children in rural areas in Tengzhou, Shandong as well as to evaluate the effi-ciency of three methods in screening amblyopia. Methods In this population-based study, children aged 5 to 14 years old in primary school were randomly selected by a cluster sampling in which school shift was the sam- piing unit. Titmus stereo-test, visual acuity (VA), cover-test and ocular motility evaluation were examined for each child. Retinoscopy was performed for children with VA < 1.0 in either eye. Results ( 1 ) Of 2668 effec-tive examinatious,369 eases (13.83%) were poor eyesight. (2) The prevalence ofamblyopia and strabismus were 1.50% and 1.72% respectively. Out of 40 amblyopia children, 39 were screened at the first time. (3) The stereoacuity in normal children was 40″, 31 (77.5%) children with amblyopia showed abnormal stereoacuity,while 28.3% for strabismus. (4) Specificity and crude agreement of combined Titmus with VA were 99.47%and 99.06% ,which were highest in the three methods. The second was Titmus stereo-test with 97.98% and 97.59%, VA was the lowest. Conelusion The most important cause of poor eyesight in primary school chil-dren is myopia. Amblyopia and strabismus might have significantly effects on stereoacuity. The most efficient method of screening amblyopia was stereo-test combined with visual acuity.

信阳市3016名学龄前儿童斜视弱视调查

为了解信阳市学龄前儿童斜视弱视的患病情况，我们于2006年9月至2007年2月对信阳市3016名学龄前儿童进行了视力调查，现将结果报告如下。     

学龄前儿童弱视及斜视的调查

目的早期发现并及时治疗弱视、斜视及其他眼病,减少可预防盲及低视力。方法济南市部分幼儿园内随机检查健康3～6岁6085例学龄前儿童,检查其标准远视力、近视力、屈光、眼位、眼前节及眼底。结果3～6岁儿童远视力低常率为12．16%,近视力低常率为4．40%；弱视患病率为5．23%,其中初次发现者占86．48%；共发现斜视患儿96例,其治疗率仅为14．58%。结论近视力可作为发现患儿视力不佳的线索之一,发现后重点核实其远视力。我市3～6岁儿童的弱视斜视的漏诊漏治情况相当严重,对幼儿尽早进行眼科普查意义重大,保健预防及宣教工作亟待加强。
