Methods Seven patients ( 9 eyes) with congenital macular coloboma who had been examined by visual acuity determination, slit lamp examination, ophthalmoscope and fluorescein angiography received OCT scan and fundus color photography. The results were retrospectively analyzed. 方法对临床经视力、裂隙灯显微镜检查以及散瞳后检眼镜眼底检查、荧光素眼底血管造影检查诊断为先天性黄斑缺损的患者7例9只眼进行OCT以及彩色眼底照相检查,对比分析OCT图像特征。
The accuracy in spectral measurement, for instance, photometric accuracy ( transmittance or reflectance), wavelength abscissa accuracy and spectral resolution, is usually influenced by spectral instrument factors, such as slit width, scan speed and response time. 光谱仪器测试参数,如狭缝宽度、扫描速度和响应时间等对光谱测试精度例如测光精度(透过率或反射率)、波长精度和光谱分辨率等有很大的影响。
