众所周知,原发性青光眼通常是双眼发病,而且往往一眼先发生青光眼而另一眼较迟也可能发生青光眼的改变,程度可不一致。早期青光眼尽管中心视力正常,但其视觉对比敏感度的降低已为很多作者证实,静态正弦光栅中心视觉对比敏感度的检测作为诊断青光眼的一种有价值的方法已逐渐被临床医生所认识,我们的工作也证实了青光眼早期主要表现以高空间频率部分的对比敏 It is well-known that primary glaucoma is usually the onset of both eyes, and glaucoma often occurs at the first glance and later glaucoma may be different, the degree of inconsistency. Early glaucoma Although visual acuity is normal at the center, the reduction in visual contrast sensitivity has been confirmed by many authors. The detection of visual contrast sensitivity at the center of static sinusoidal gratings has been increasingly recognized by clinicians as a valuable method for diagnosing glaucoma. The work also confirmed the main manifestations of early glaucoma with high spatial frequency of the contrast sensitivity
