眼科专家在临床上将青光眼病分为原发性青光眼、继发性青光眼和先天性青光眼三大类型。后面两种青光眼虽然比较难治,但毕竟这种病人不多,比较常见的是原发性青光眼病,折磨着众多的患者。到目前为止,原发性青光眼的病因还不十分清楚。临床研究表明,病眼有解剖和生理上的缺陷,如房角狭窄或房角小梁组织变性,致使房水排出比较困难,容易引起眼压升高。但是,直接原因是患者的血管神经和大脑中枢发生调节障碍,使眼内血管收缩和扩张失常,造成眼球瘀血和房水排出困难。 Ophthalmologists in clinical glaucoma will be divided into primary glaucoma, secondary glaucoma and congenital glaucoma three types. Although the latter two glaucoma more difficult to treat, but after all, this small patient, the more common is primary glaucoma, afflicting many patients. So far, the etiology of primary glaucoma is not yet clear. Clinical studies have shown that the eye has anatomical and physical defects, such as narrowing angle or trabecular tissue degeneration, resulting in aqueous humor discharge more difficult, likely to cause elevated intraocular pressure. However, the direct cause is that the patient’s vascular nerves and the central nervous system disorders occur, so that intraocular vasoconstriction and dilatation disorders, resulting in eyeball bleeding and aqueous discharge difficulties.
