简介：目的探讨显微镜下视网膜脱离复位手术的临床效果。方法孔源性视网膜脱离36例（36眼）由同一术者进行外路手术，均在术中应用手术显微镜进行裂孔定位。冷凝封闭及巩膜外垫压。定期观察术后视力、眼内反应和视网膜复位情况。结果经显微镜直视下外路手术患者，术后随访15d-167d，视网膜完全复位35眼（97．2％），视力较术前提高33只眼（91．7％），不变2只眼，下降1只眼。最好矫正视力0．3以上33只眼（91．7％）。术后所有患者视网膜冷凝反应I-Ⅱ级，无Ⅲ-Ⅳ级。轻度屈光介质浑浊不影响手术过程。结论经手术显微镜直视下外路治疗孔源性视网膜脱离安全有效、简单可行，值得推广。

简介：目的观察羊膜移植联合亲水角膜接触镜治疗早期眼烧伤的临床疗效.方法21例（21眼）早期眼烧伤患者,采用羊膜移植并佩戴亲水性软性角膜接触镜治疗,术后随访3月.结果所有患眼术后症状均有不同程度缓解；20例眼表基本稳定,视力不同程度提高；2例角膜云翳；l例眼结膜表层重建,但发生角膜斑翳.无严重眼部并发症发生.结论羊膜移植联合亲水性角膜接触镜治疗各种早期眼烧伤安全、有效,值得在临床上广泛推广使用.
