为探讨红外激光扫描检眼镜（SLO）在眼底疾病诊断中的应用，我们自制了一台SLO。红外光从眼底反射的程度大于可见光，从而允许较低的照明功率，并且当红外光穿透视网膜色素上皮时，脉络膜结构可以容易地成像。此外，由于传统的红外照明和检测系统不太适合检眼镜检查，该领域作为有用的临床数据的潜在来源还不发达。共焦、直接和间接成像模式已被用于正常志愿者和眼底疾病患者的眼底成像。与传统眼底照相相比，共焦红外SLO成像改善了脉络膜血管、视网膜色素上皮异常、激光光凝疤痕和筛板中视盘孔的可视化。直接红外SLO成像能够通过核透镜混浊实现眼底可视化。此外，间接模式成像显著增强黄斑玻璃疣的外观。这些观察结果的潜在临床受益进行了讨论。
An infrared scanning laser ophthalmoscope (SLO) has been custom built in order to investigate the application of confocal and indirect mode SLO imaging to patients with fundus disease. Infrared light is reflected from the fundus to a greater extent than visible light permitting lower illumination power and, as it penetrates the retinal pigment epithelium, choroidal structures can be readily imaged. Furthermore, as conventional infrared illumination and detection systems are not well suited to ophthalmoscopy, this area is underdeveloped as a potential source of useful clinical data. Confocal, direct and indirect imaging modes have been used to image fundi of normal volunteers and patients with fundus disease. In comparison with conventional fundus photography confocal infrared SLO imaging improves visualisation of choroidal vasculature, retinal pigment epithelial abnormalities, laser photocoagulation scars, and optic disc pores in the lamina cribrosa. Direct infrared SLO imaging enables fundus visualisation through nuclear lens opacities. Furthermore, indirect mode imaging enhances significantly the appearance of macular drusen. The potential clinical benefit of these observations is discussed.
