青光眼是以高眼压合并视功能障碍为特征的一种眼病。目前在日本,40岁以上的人本病发病率约为1.0～2.0%(共约100万人)。在各先进国家中,青光眼与糖尿病性视网膜病并居后天性失明原因的首位。青光眼起因于眼压升高。一般来说,如果房水流动正常,眼压就会保持在15±3mmHg这一正常范围之内。已知,眼压在一天之内可出现生理性波动,清晨较低,午后则有所升高。因此,很多研究者认为,身体的某一部位
Glaucoma is an ocular condition characterized by ocular hypertension combined with dysfunction. Currently in Japan, the incidence of the disease over the age of 40 is about 1.0 to 2.0% (about 100 million people). In all advanced countries, glaucoma and diabetic retinopathy are among the top causes of acquired blindness. Glaucoma arises from intraocular pressure. In general, if aqueous humor flows normally, intraocular pressure will remain within the normal range of 15 ± 3 mmHg. It is known that intraocular pressure may fluctuate physiologically within a day, lower in the early morning and somewhat higher in the afternoon. Therefore, many researchers think that a certain part of the body
