青光眼是以眼压增高、视乳头凹陷和视野缺损为特征的综合性眼病。而视乳头凹陷和视野缺损又被认为是高眼压的结果,因而在青光眼诊断上,把眼压增高做为一个重要体征。在以往曾一度把眼压高于正常者,都诊断为青光眼,但后来发现,有些眼压正常或低于正常的病例,视功能损害与眼压高的青光眼相似;又发现有些高眼压的病人没有青光眼的损害,因而得出高眼压者不一定都是青光眼,而眼压正常或偏低者不一定都不是青光眼的结论。鉴于这种认识,近十几年来提出了“高眼压症”的诊断名称。所谓“高眼压症”是指未用药物治疗,一眼或双眼二次以上测眼压均大于或等于21mmHg,没
Glaucoma is a comprehensive ocular disease characterized by increased intraocular pressure, optic nerve pits and visual field defects. The optic disc depression and visual field defect is also considered as the result of high intraocular pressure, glaucoma in the diagnosis, the increased intraocular pressure as an important sign. In the past once the intraocular pressure higher than normal, were diagnosed with glaucoma, but later found that some intraocular pressure normal or lower than the normal case, visual impairment and glaucoma with high intraocular pressure similar; also found that some ocular hypertension Patients without glaucoma damage, which concluded that high intraocular pressure are not necessarily all glaucoma, and intraocular pressure is normal or low are not necessarily the conclusion of glaucoma. In view of this understanding, in the past ten years put forward the diagnosis of “ocular hypertension”. The so-called “ocular hypertension” refers to the unmedicated treatment, one or two times more than twice the measured intraocular pressure were greater than or equal to 21mmHg, no
