We have used the scanning laser opthalmoscope (SLO) with a personal computer to develop static microperimetry techniques. They allow to see in real-time on a television monitor the precise retinal localization of the stimulus and fixation. The testing is performed under strict conditions. The size of stimuli can vary between 6 and 30 minarc on a side. 255 different intensity levels are possible with the instrument. We have selected 12 of them, representing a logarithmic scale. Stimulus duration can vary between 50 and 500 ms. Examples of macular pathology including subretinal neovascularization, drusen and macular edema are given.
我们使用配备个人计算机的扫描激光检眼镜（SLO）开发了静态微视野检查技术。这些技术能在电视监视器上实时看到刺激物和注视点在视网膜上的精确位置。测试在严格条件下进行。刺激物的边长大小可在6到30分角之间变化。该仪器可有255种不同的强度级别。我们选择了其中12种，代表一个对数标度。刺激持续时间可在50到500毫秒之间变化。文中给出了黄斑病变的例子，包括视网膜下新生血管形成、玻璃膜疣和黄斑水肿。
