types of glaucoma
There are several types of glaucoma. Treatment depends on properly identifying precisely which kind is present and determining how the glaucoma may affect the person's quality of life. The goal of treatment is preservation of health.The factor common to all types of glaucoma is damage to the optic nerve of the eye. This damage is related to the pressure inside the eye. No matter whether the pressure is high, normal or below normal, it can still cause damage. Most types of glaucoma are chronic, and are present for the person's lifetime. Some types of glaucoma occur suddenly, but most develop slowly, over months or years.
Most types of glaucoma need some form of treatment. Some people need surgery. Others may need medicine to treat the eye directly, or to treat some other health problem that is affecting the eye. Still others may need to have certain medicines stopped.

理想的疾病分类既能反映病因和病机，又能指导临床诊断和治疗。但由于青光眼病因复杂，至今尚没有一个很完善的分类方法，目前常用的方法是根据前房角形态和发病年龄将青光眼分为开角型青光眼、闭角型青光眼、先天性青光眼。
根据导致眼压升高的病因，每一种青光眼又分为原发性和继发性。那些发病原因尚不明确的青光眼称原发性青光眼，可分为原发性开角型青光眼、可疑青光眼与高眼压症、正常眼压(低眼压)青光眼、原发性闭角型青光眼(伴瞳孔阻滞、无瞳孔阻滞)、原发性先天性青光眼、伴先天异常的发育性青光眼。
继发性青光眼的发病原因是清楚的，根据病因结合房水排出障碍的机制可分出多种类型，大致分为继发性开角青光眼、继发性闭角青光眼和继发先天性(发育型)青光眼。临床上常见继发性青光眼有以下几类：炎性疾病所致青光眼(如青光眼睫状体炎综合征)、虹膜角膜内皮综合征、色素性青光眼、剥脱综合征、眼外伤所致青光眼(如房角后退性青光眼)、眼内出血所致的青光眼(如血影细胞性青光眼)、晶体异常所致的青光眼(如晶体溶解性青光眼)、新生血管性青光眼、恶性青光眼(或睫状环阻滞性青光眼)、皮质类固醇性青光眼(或激素性青光眼)。
临床上有时见到两种或两种以上青光眼共同出现，称为混合性青光眼。常见临床类型有开角型青光眼与闭角型青光眼混合、开角型青光眼与继发性青光眼混合、闭角型青光眼与开角型青光眼混合、闭角型青光眼继发性青光眼混合。
