目的:测量中国人的角膜后弹力层厚度并分析其与年龄的关系。方法:收集27例角膜标本,年龄范围从0.2岁到78岁,所有标本经HE染色后行组织切片并通过400倍光学显微镜行显微照相,于每张相片中选取四个测量点并人工标记后弹力层的边界,通过软...目的:测量中国人的角膜后弹力层厚度并分析其与年龄的关系。方法:收集27例角膜标本,年龄范围从0.2岁到78岁,所有标本经HE染色后行组织切片并通过400倍光学显微镜行显微照相,于每张相片中选取四个测量点并人工标记后弹力层的边界,通过软件Motic Images Plus 2.0自动计算其厚度并取平均值。采用线性回归方法分析角膜后弹力层厚度与年龄的关系。结果:所有标本的角膜后弹力层厚度为1.78μm到9.30μm,平均4.63±2.00μm。角膜后弹力层厚度与年龄具有高正相关性(r=0.776,P=0.000),线性回归方程可描述为:角膜后弹力层厚度(μm)=2.010+0.063年龄(岁)。结论:中国人的角膜后弹力层厚度与年龄之间具有显著正相关性。展开更多
Descemet’s membrane detachments （DMD） are relatively common after cataract surgery and most do not require any treatment. However, if large DMD are not treated appropriately, significant visual morbidity can ensue....Descemet’s membrane detachments （DMD） are relatively common after cataract surgery and most do not require any treatment. However, if large DMD are not treated appropriately, significant visual morbidity can ensue. We aim to develop a guideline for the management of DMD post cataract surgery based on a retrospective review of all cases encountered at the Royal Victorian Eye and Ear Hospital, Melbourne, Australia over a 4-year period from 2010 to 2014. We suggest conservative management if the visual axis is not involved; however, after 3mo surgical intervention may be warranted to prevent corneal sequelae. In cases where the visual axis is involved we suggest early intervention with air tamponade. The main risk factor for irreversible corneal oedema and subsequent endothelial transplant appears to be direct endothelial trauma rather than the DMD itself.展开更多
