对高眼压症病人进行治疗是否能防止青光眼性视野损害,从三方面考虑,对大部分病人的回答是否定的。(1)在不治疗的高眼压中视野损害的平均危险性是很小的。普查和预期的研究表明,眼压高于20mmHg者每9人中可能发生视野缺损者不超过1人。(2)经治疗降低眼压后是否有防止视野缺损的效果尚未证明。(3)青光眼治疗中常常有副作用,有时还是非常严重的。因此,对某些病人来讲在青光眼性视力丧失以前降低眼压是必要的,但从多方面考虑对大部分高眼压者不治疗而严密观察是较明智的。高眼压症的危险性不治疗高眼压症至少可能有三个途径对眼造成损害,即角膜水肿;易发生中央静脉阻塞;可
The treatment of ocular hypertension patients can prevent glaucomatous visual field damage, from three aspects, the answer to most patients is negative. (1) The average risk of visual field damage in untreated ocular hypertension is very small. Census and prospective studies have shown that intraocular pressure greater than 20mmHg per nine people may occur in less than one person with visual field defects. (2) After treatment to reduce intraocular pressure to prevent the effect of field defect has not been proved. (3) Glaucoma treatment often has side effects, sometimes very serious. Therefore, it is necessary for some patients to reduce IOP before glaucomatous loss of visual acuity, but it is advisable to look closely at most patients without ocular hypertension for many reasons. The risk of ocular hypertension No treatment of ocular hypertension There are at least three ways to cause damage to the eye, namely corneal edema; prone to central vein occlusion;
