Glaucoma affected the ability to detect low-contrast, flickering patterns ('DRC' measurement). DRC patterns were foveally viewed, of low spatial frequency, and flickering at 8 hertz. Interocular comparisons were performed in control subjects, in ocular hypertensives, and in glaucoma patients with asymmetric damage. Interocular differences in DRC tended to be of greater magnitude in the glaucoma patients than in the ocular hypertensive patients or control subjects. In the glaucoma patients DRC was consistently lower in the eye with the greater field defect than in the other (more normal) eye. In patients with optic disc asymmetry DRC was lower in the eye with the more abnormal disc. Treatment asymmetries did not appear to play a significant role in these relationships. When examined by interocular comparisons DRC showed no consistent relationship to Snellen visual acuity or to level of intraocular pressure at the time of DRC testing.
青光眼影响了检测低对比度闪烁图案（“DRC”测量）的能力。DRC图案是在中央凹观察的，空间频率低，闪烁频率为8赫兹。在对照受试者、高眼压患者和不对称损伤的青光眼患者中进行了双眼比较。青光眼患者的DRC眼间差异往往比高眼压患者或对照受试者更大。在青光眼患者中，视野缺损较大的眼睛的DRC始终低于另一只（更正常）眼睛。在视盘不对称的患者中，视盘更异常的眼睛的DRC较低。治疗不对称似乎在这些关系中不发挥重要作用。通过双眼比较检查时，DRC与斯内伦视力或DRC测试时的眼压水平没有一致的关系。
