关于低眼压性青光眼(LTG)视野缺损的特点尚有争论,许多人认为它与慢性开角型青光眼(COAG)的视野缺损无区别,但有人发现LTG中,等视力线型视野缺损(altitudinal field defect)的发现率较高。Levene在32例LTG中,发现94%有注视点5°以内的浓密缺损(dense defeets),而在160例COAG中仅有20%,因此他认为LTG和COAG的视野缺损虽在性质上相同,但其量上有差异,即LTG中近注视点的浓密缺损表现率较高。根据这种差别,有人推断LTG
There are controversies about the characteristics of visual field defects in low tension glaucoma (LTG), which many consider as having no difference in visual field defects in patients with chronic open-angle glaucoma (COAG). However, it has been found that in LTG, The discovery rate of field defect is higher. In 32 LTGs, Levene found that 94% had dense defests within 5 ° of fixation and only 20% of 160 patients with COAG, so he considered the visual field defects of LTG and COAG to be the same in nature, However, there are differences in quantity, that is, the performance of dense defect in LTG is higher than that of near view. According to this difference, some people infer LTG
