在应用多色光(氙光)光凝时,一般以检眼镜所见的光凝斑的形态作为估计光凝所产生的损伤程度的标准,从而来估定光凝剂量。但是,在应用单色光(激光)光凝时,光凝斑的深度位置随激光波长的不同而有差异,因而检眼镜所见的形态也有所不同,因此,不能以此来确定光凝剂量。 In the application of multi-color light (xenon light) photocoagulation, the ophthalmic dose is generally estimated based on the morphology of photocoagulation spots seen with ophthalmoscopes as a measure of the degree of damage caused by photocoagulation. However, the application of monochromatic laser (laser) photocoagulation, the depth of the spot of the laser spot varies with the laser wavelength, so the ophthalmic lens to see the morphology is also different, therefore, can not be used to determine the amount of photocoagulation .
