[Static microperimetry with the laser scanning ophthalmoscope].
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.
