晶状体病 DISORDERS OF LENS 哈尔滨医科大学第一临床医学院附属 眼科医院 EYE HOSPITAL OF THE 1ST CLINICAL MEDICAL COLLEGE, HMU
晶状体(lens)为双凸形状,有弹性,是 无血管的透明组织,具有复杂的代谢过 程。营养主要来自房水。它是眼屈光间 质重要的组成成分。主要的病变是其透 明度和位置的改变,都会严重影响视力 The lens is a kind of avascular transparent tissue with complex metabolic process. Its nourishment mainly comes from aquous humour. The disorder of the lens is commonly loss of its transparency and abnormality of its position; both can induce severe visual disturbance

白内障 CATARACT 概述( Introduction) 广义上讲晶体发生混浊就可称为白内 障( cataract),但只有对视力有影响 时,才有临床意义。 The opacity of lens is generally called cataract. But mild opacity of the lens has no affection to vision without any clinical Significance

病因( Etiology):许多因素,如老化、 遗传、代谢异常、外伤、辐射、中毒 局部营养障碍等,引起晶状体囊膜损 伤,使其通透性增加和丧失屏障作用, 或导致晶状体代谢紊乱,都可使晶状 体蛋白质发生变性,造成混浊

白内障的分类 CLASSIFICATION OF CATARACT 1.按病因( according to etiology):分 外伤性 (injuried)、并发性 ( complicated)、代谢性( metabolic)、 中毒性( (toxic)、辐射性( radiating)、 发育性( develoing )和后发性(afer cataract)白内障
