To evaluate bioelectrical function of inner retinal layers measured by PERG in normal tension glaucoma.
In 50 eyes of 30 patients with normal tension glaucoma the following examinations were performed: history, routine ophthalmic examination, standard static perimetry and pattern ERG test.
The most frequent abnormalities were incorrect N95/P50 amplitude ratio and increase latency of N95-wave. In analyzed glaucoma patients sensitivity of PERG test was 50% and specificity 87%.
In normal tension glaucoma, the ganglion cells dysfunction is present and can be detected with PERG test. PERG can be additional useful diagnostic test in patients with normal tension glaucoma, particulary for those with difficult to cooperate.
评估通过图形视网膜电图（PERG）测量的正常眼压性青光眼中视网膜内层的生物电功能。
对30例正常眼压性青光眼患者的50只眼睛进行了以下检查：病史、常规眼科检查、标准静态视野检查和图形视网膜电图（ERG）测试。
最常见的异常是N95/P50振幅比不正确和N95波潜伏期延长。在所分析的青光眼患者中，PERG测试的敏感性为50%，特异性为87%。
在正常眼压性青光眼中，存在神经节细胞功能障碍，并且可以通过PERG测试检测到。PERG对于正常眼压性青光眼患者可能是一项额外有用的诊断测试，特别是对于那些难以配合的患者。
