黄斑变性(1)

简介:

? ? ? ?黄斑变性为黄斑区结构的衰老性改变。主要表现为视网膜色素上皮细胞对视细胞外节盘膜吞噬消化能力下降,结果使未被完全消化的盘膜残余小体潴留于基底部细胞原浆中,并向细胞外排出,沉积于Bruch膜,形成玻璃膜疣。因此继发病理改变后,导致黄斑变性发生,总之主要与黄斑区长期慢性光损伤,脉络膜血管硬化,视网膜色素上皮细胞老化有关,由此继发的种种病理改变后,则导致黄斑部变性发生。

分类:

? ? ? ?分为年龄相关性黄斑变性和少年黄斑变性两种:年龄相关性黄斑变性,也称老年黄斑变性(AMD)。本病大多发生于45岁以上,其患病率随年龄的增长而增高,是当前中老年人致盲的重要疾病。

临床表现:

? ? ? ?临床表现 本病分萎缩性与渗出性两型已如前述,也有人观察到萎缩性可以转化成渗出性,因此认为有分型的必要。然而就大多数病例来说,临床表现轻重与预后优劣二型是截然不同的。

治疗及预防

1、预防为主,早期治疗 ? ? ? ?黄斑变性,黄斑区玻璃疣是在本病病程的最早期阶段,病变最轻,但它潜伏的危险性很大,此时最不可麻痹大意。少年黄斑变性的患者,早期中心视力有所下降,但眼底改变不明显,此时应及时发现早期用药,坚持治疗。在任何疾病的过程中,病程最早期,病变最轻阶段,都是最好的治疗时机,有更多的机会阻止病程进展。 2、急重病例,标本共治 ? ? ? ?当黄斑区出现血性色素上皮脱离,神经上皮脱离以及积血进入玻璃体,是病程急剧进展,视功能严重受损的征象,这种病例常反复发作,直至视力严重损伤或完全丧失。对于这种严重病例,必须全力积极治疗,我们会根据病情的不同阶段,运用不同的治疗方法。
