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：随着研究生招生观念的转变，招收的医学临床专业学位研究生的比重越来越大，对专业型研究生的培养也越来越注重实用。我们在眼科专业型研究生临床培养中，增加病房临床实践时间，特别注重典型病例的示范作用，每一个专业组都会结合自己专业的特点，将典型病例的特点从各个角度展示给广大研究生们，培养其临床诊治思辨能力，培训其显微手术技巧，从临床病历书写到记录总结，结合文献复习，拓展知识结构，锻炼专业型研究生论文书写能力，并以典型病例为基础，扩展知识覆盖面，引申注意事项及特殊病例的诊治。这套严格的培养体系，使专业型研究生能举一反三，从典型病例、重点病例中获取对该种病情的最直观的全景了解与熟悉，以最少的时间掌握最多的临床知识，丰富临床经验，为将来工作岗位中的考核打下基础。
