低压性青光眼(LTG)是指具有典型的青光眼性视乳头凹陷和视野改变,房角开放,而眼压则在统计学的正常值范围。作者复习了有关这一专题的大量文献,对LTG作了比较系统的叙述。有关资料主要来自两个方面:(1)1857～1946年由Sjgren所写的文献综述;(2)自1947年～1979年作者所复习的近代文献及作者自己所观察随访的32个病例。由于LTG的原因十分复杂,作者采用了一种描述性的定义,其标准为:(1)单眼或双眼后天性原发性开角型青光眼(POAG)样的视野缺损;(2)单眼或双眼后天性POAG样视乳头改变;(3)多次测定未经治
Low-pressure glaucoma (LTG) refers to a typical glaucoma optic disc depression and visual field changes, open angle, and intraocular pressure in the statistical range of normal. The author reviewed extensive literature on the topic and made a more systematic account of LTG. The data mainly come from two aspects: (1) a literature review written by Sjgren from 1857 to 1946; (2) modern literature reviewed by the authors from 1947 to 1979 and the 32 cases followed by the authors themselves. Because of the complex nature of LTG, the authors adopted a descriptive definition whose criteria are: (1) monocular or binocular primary open-angle glaucoma (POAG) -like visual field defects; (2) monocular or bilateral Acquired POAG-like nipple change; (3) repeatedly measured without treatment
