简介：目的探讨施行角膜层间分离灼烙术治疗大泡性角膜病变的临床效果.方法对14例大泡性角膜病变患者施行8～9mm深达1/2角膜的层间分离及灼烙.结果所治病例角膜愈合良好,无不良反应,眼痛、异物感症状消失,视力有不同程度改善,随访6～24个月,临床疗效稳定.结论角膜层间分离灼烙术为不具备穿透性角膜移植的大泡性角膜病变提供了一种简便、安全、不需特殊材料、较为理想的手术方法.

简介：目的：评价羊膜移植几种手术方法治疗大泡性角膜病变的临床效果。方法：对18例大泡性角膜病变患者，分别采取角膜层间烧烙术、新鲜羊膜移植术、角膜灼烙联合羊膜嵌入移植手术。结果：18例大泡性角膜病变患者，术后1～5d疼痛消失，7～12d角膜上皮修复，7～21d后羊膜植片常规溶解。角膜层间烧烙术1眼、新鲜羊膜移植术3眼术后1～2mo再次出现角膜大泡及角膜刺激症状而再次手术。角膜灼烙联合羊膜嵌入移植术，术后当天疼痛消失，14d角膜上皮光滑，角膜大泡消失。随访6～18mo无1例复发，部分患者视力有不同程度的提高。结论：角膜灼烙联合羊膜嵌入移植对大泡性角膜病变具有明显的治疗效果.

简介：超声乳化术已经成为了目前治疗老年性白内障的主要手术方式。随着超声乳化术的广泛应用，该种术式对于眼前节结构和功能影响的研究也层出不穷。本文回顾了近几年来国内外这方面的相关文献，阐述了超声乳化术对眼前节结构和功能的影响。

简介：为探讨迷路的老化过程,应用透射电镜观察了新生、青年、老年豚鼠的耳蜗和迷路血管系统的变化。发现老年豚鼠血浆成分有改变、听力呈下降倾向;毛细胞、迷路血管及螺旋神经和螺旋神经节细胞均可见一系列损害。作者推测在耳蜗老化过程中血管系统的变化非常重要,至少是耳蜗其他部位老年性改变的原因之一。

简介：目的:评价大剂量甲基强的松龙对原田病急性期浆液性视网膜脱离的治疗作用.方法:对2001-12/2003-07就诊本院患者11例(22眼)在临床诊断当天即给予甲基强的松龙静脉滴注,剂量为500mg,1次/d,连续用3d后迅速减量,于7d内减为强的松口服.OCT和间接眼底镜观察炎症渗出吸收情况,检查视功能恢复情况.结果:大剂量甲基强的松龙静脉滴注次日即可观察到22眼视网膜下液均明显减少,静滴3d后浆液性视网膜脱离基本消失,视网膜复位,出院时21眼视网膜下液完全吸收,14眼(64%)视力恢复至0.5以上.结论:甲基强的松龙冲击疗法可促进原田病急性期视网膜下液迅速吸收,恢复视功能,疗效可靠,值得临床推广.

简介：目的：观察早期衰老大鼠视网膜色素上皮-光感受器细胞复合体超微结构的变化。方法：取3月龄及12月龄大鼠视网膜,制成半薄切片,透射电镜下观察视网膜色素上皮-光感受器细胞复合体超微结构的变化。结果：12月龄大鼠视网膜中出现视网膜色素上皮细胞（retinalpigmentepithelium,RPE）凋亡和RPE-光感受器细胞复合体的退行性改变。结论：视网膜色素上皮-光感受器细胞复合体的退行性改变是视网膜衰老的早期表现。
