目的研究合并高度近视的青光眼和非高度近视的青光眼的视野改变有无差别。方法 利用Octopus 101全自动视野计对36例(51眼)合并高度近视的原发性开角型青光眼(primary open angle glaucoma,POAG)和16例(23眼)非高度近视的POAG进行静态中心阈值视野检查,并分析其视野缺损形式,视野缺损与生理盲点及固视点的关系和视野指数的改变。结果合并高度近视的POAG视野缺损形式与非高度近视的POAG视野缺损形式相似,差异无显著性(早期POAG,X~2=0.000138,P>0.05,中晚期POAG,X~2=1.1494,P>0.05)。合并高度近视的POAG视野缺损较多的与生理盲点相速或/和与固视点相近(或相连),但与非高度近视的POAG相比,差异无显著性(早期POAG,X~2=1.3892,P>0.05,中晚期POAG,X~2=2.6852,P>0.05)。随着近视度数的增加,MS值逐渐下降,MD和LV值逐渐升高。结论 合并高度近视的POAG视野缺损较多的与生理盲点和/或固视点相连或相近,近视度数越高,其视野损害越明显。
Objective To investigate whether there is any difference in the visual field between glaucoma with high myopia and non-highly myopic glaucoma. Methods Thirty-six patients (51 eyes) with POAG (primary open angle glaucoma, POAG) with high myopia and 16 POAG (23 eyes) with non-high myopia were examined by Octopus 101 automatic static field technique. Visual field examination, and analysis of its visual field defect form, visual field defects and physiological blind spots and fixation point relationship and visual field index changes. Results POAG visual field defect with high myopia was similar to POAG visual field defect without high myopia (POAG, X ~ 2 = 0.000138, P> 0.05, POAG in middle and late stage, X ~ 2 = 1.1494, P> 0.05). POAG visual field defect with high myopia with physical blind spot more or / and focal point similar (or connected), but non-high myopia POAG, no significant difference (early POAG, X ~ 2 = 1.3892 , P> 0.05, advanced POAG, X ~ 2 = 2.6852, P> 0.05). With the increase of myopia, MS value decreased gradually, MD and LV values gradually increased. Conclusions POAG visual field defects with high myopia are more connected with or close to the physiological blind spots and / or fixation points. The higher the myopia degree, the more obvious the visual field damage.
