简介：目的：探讨机械性眼外伤的临床特征及诊疗结果分析。方法：收集我院收治的机械性眼外伤122例122眼的临床资料,进行记录及回顾性分析。结果：机械性眼外伤122例中,开放性眼外伤116眼（95.1%）,闭合性眼外伤6眼（4.9%）,男女之比6.18∶1,机械性眼外伤以眼球开放性损伤为最多,致伤多以异物为主,经过及时手术治疗,全部保住了眼球,与入院视力相比,出院视力得到明显提高。结论：工作和生产意外是机械性眼外伤的主要原因,病情复杂,合并症多,后果严重,应加强防范。及时的医院就诊和眼科显微手术技术的提高及玻璃体视网膜手术的开展是挽救伤眼视力、降低机械性眼外伤并发症的有效措施。

简介：目的：观察波前像差引导LASIK与波前像差优化LASIK对全眼高阶像差在0.3滋m以下近视散光眼的疗效差异。方法：前瞻性病例系列研究。收集在我院就诊拟行LASIK手术的近视散光患者30例60眼。每位患者随机选取一眼接受波前像差引导的LASIK,对侧眼接受波前像差优化的LASIK。术后6mo观察患者的视力、屈光度、全眼高阶像差及暗光下对比敏感度。采用配对样本t检验和字2检验进行统计学分析。结果：术后6mo,波前像差引导组与波前像差优化组分别有93%及90%的术眼裸眼视力逸5.0,两组术后等效球镜值在±0.50D范围内的比例分别为87%及83%,差异无统计学意义（P〉0.05）。两组术后均未出现最佳矫正视力丢失2行或以上的情形。两组术后总高阶像差、球差、彗差均较术前增大（P〈0.01）,但增幅在两组间无统计学差异（P〉0.05）。两组术后6mo暗光下对比敏感度在各个空间频率均恢复至术前水平,差异无统计学意义（P〉0.05）。结论：对术前全眼高阶像差小于0.3滋m的近视散光眼,波前像差引导LASIK与波前像差优化LASIK对术后视力、屈光度、全眼高阶像差及对比敏感度的影响无明显差异。

简介：目的：运用PlusoptixA09小儿自动测光仪探测雅加达地区学龄前儿童屈光不正及其他眼病的发生情况。方法：对雅加达的三个地区（南唐格朗,勿加泗和西雅加达）三所幼儿园中,平均年龄4.46岁（2～6周岁）的儿童进行屈光不正及其他眼病检测。结果：受检的166名儿童中,男生占51.2%（n=85）,女生48.8%（n=81）。视力筛选以Arthur修定标准为参考,并为15.67%（n=26）的儿童做更深一步的全面性眼部检查。其中2人高度远视,14人严重散光,6人散光加近视,1人屈光参差,1人无法检测,2人患有其他眼病（由慢性咳嗽导致的先天性眼睑下垂、严重瘀斑和结膜下出血）。结论：本研究表明,运用PlusoptixA09测出弱视危险因素结果为15.67%。此项数据表明,印度尼西亚地区医疗保健人员对学龄前儿童视力筛选工作不够重视,尤其是对不可逆性弱视的危害性重视度不够。
