In this article, the methodologies and clinical applications of microperimetry performed by scanning laser ophthalmoscope (SLO) are described. This technique provides functional results by direct visualization of the macular area. We present the most interesting data about clinical applications in ocular pathology. SLO microperimetry is a new diagnostic tool in ophthalmic practice. It permits an exact, point-to-point correspondence between fundus image and perimetric results, impossible to achieve by projection perimetry, so representing the most suitable device for simultaneous fundus imaging and psychophysical testing. Microperimetry is performed by SLO (Rodenstock),1 which permits other applications. SLO microperimetry allows the real-time functional study of retinal sensitivity by direct ophthalmoscopic control of the retinal surface. Foveal or excentric fixation can be assessed as well. Instability of fixation during computerized perimetry is a possible misleading factor resulting in unexplainable findings, especially in eyes with decreased visual acuity. The main characteristic of microperimetry is the ability to see the stimuli presented on the retina in real time: this permits an accurate monitoring of fixation and correlation of anatomical or pathological features directly with retinal function.
本文描述了使用扫描激光检眼镜（SLO）进行微视野计检查的方法及其临床应用。该技术通过直接观察黄斑区提供功能检测结果。我们展示了有关眼部病理学临床应用的最有趣数据。SLO微视野计是眼科实践中的一种新型诊断工具。它能实现眼底图像与视野检测结果之间精确的点对点对应，这是投影视野计无法做到的，因此是同时进行眼底成像和心理物理学测试的最合适设备。微视野计检查由SLO（罗敦司得）完成，1它还允许进行其他应用。SLO微视野计通过直接检眼镜控制视网膜表面，对视网膜敏感度进行实时功能研究。中心凹或偏心注视也可以进行评估。在计算机化视野检查期间注视不稳定是一个可能导致误导性结果的因素，尤其是在视力下降的眼睛中，会产生无法解释的结果。微视野计的主要特点是能够实时看到视网膜上呈现的刺激：这使得能够准确监测注视情况，并直接将解剖学或病理学特征与视网膜功能相关联。
