Ⅰ.序言低眼压青光眼(LTG)是一种概念不清的疾病,由于各著者定义内容不同,对其本质更难以理解。著者认为LTG原发开角青光眼(POAG)的一型,并在眼压始终不超过21mmHg的病例中附合青光眼的诊断标准即为LTG。而且必须明确的是最终一定是青光眼。如在视神经乳头出现同眼压无关很像青光眼凹陷的所见,以及视野出现异常的疾病,应属其他范畴(图1),从这一观点出发,谈谈LTG的诊断和治疗。 I. Preface Hypoglycemic glaucoma (LTG) is an ill-defined disease that is harder to understand because of the different definitions of each individual. The authors consider the LTG primary open angle glaucoma (POAG) type and the diagnostic criteria for glaucoma in cases where intraocular pressure is consistently less than 21 mmHg. And it must be clear that in the end it must be glaucoma. If the occurrence of optic disc with the intraocular pressure has nothing to do with glaucoma depression seen, as well as visual field abnormalities should belong to other areas (Figure 1), from this point of view, talk about the diagnosis and treatment of LTG.
