暗视阈值反应（STR）是完全暗适应状态下．很弱刺激光强记录到的潜伏期很长、振幅很小的负相渡。我们检测了18例（24只眼）正常眼．22例（39只眼）视网膜病变和10例（10只眼）视神经病变的STR，观察到16例（24只眼）视网膜病变的STR异常和消失．而10例（10只眼）视神经病变的STR完全正常。结果表明，STR对视网膜病变具有一定的诊断价值。
The dark vision threshold response (STR) is completely dark-adapted. Very weak stimulation of light recorded long latency, amplitude of a small negative phase crossing. We examined 18 patients (24 eyes) with normal eyes. Twenty-four (24 eyes) retinopathy of STR were observed abnormalities and disappearance of STR in 22 (39 eyes) and 10 (10 eyes) retinopathies. While 10 cases (10 eyes) of optic nerve lesions STR completely normal. The results show that STR has a certain diagnostic value of retinopathy.
