To evaluate the association between the watershed zone and glaucomatous optic nerve head (ONH) damage.
We performed indocyanine green fluorescence angiography with a scanning laser ophthalmoscope in 54 eyes of 27 patients with normal tension glaucoma (NTG).
We identified 7 eyes of 8 patients (14.8%) with a watershed zone not including the ONH, 32 eyes of 20 patients (59.3%) with the watershed zone partially including the ONH, and 10 eyes of 14 NTG patients (25.9%) with the watershed zone including the ONH. Of the 27 NTG patients, 10 patients (37.0%) had different types in each eye.
In these patients, the mean deviation of visual field indices was greater in the eye with the watershed zone, which included a larger part of the ONH than in the contralateral eye. Conversely, the eye with the greater mean deviation had a watershed zone that included a larger part of the ONH. The location of the watershed zone appeared to influence the progression of the visual field defect.
评估分水岭区与青光眼性视神经乳头(ONH)损害之间的关联。
我们使用扫描激光检眼镜对27例正常眼压性青光眼(NTG)患者的54只眼睛进行了吲哚菁绿荧光血管造影。
我们发现8例患者的7只眼睛(14.8%)的分水岭区不包括ONH,20例患者的32只眼睛(59.3%)的分水岭区部分包括ONH,14例NTG患者的10只眼睛(25.9%)的分水岭区包括ONH。在27例NTG患者中,10例患者(37.0%)每只眼睛的类型不同。
在这些患者中,分水岭区包括更大比例ONH的眼睛的视野指数平均偏差大于对侧眼睛。相反,平均偏差较大的眼睛的分水岭区包括更大比例的ONH。分水岭区的位置似乎影响视野缺损的进展。
