Do [ Evaluation of ganglion cells function with PERG test in normal tension glaucoma patients ]? Context: 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%.
