The use of high-intensity illumination devices is routine for many ophthalmic diagnostic and therapeutic procedures. However, the exposure of patients to high-level photic energy may be damaging even in the absence of visible abnormalities. Devices such as the operating microscope, indirect ophthalmoscope, and endoilluminator are capable of irradiances sufficient to cause retinal damage and should be used with a degree of restraint that reflects a recognition of their potential for phototoxicity.
对于许多眼科诊断和治疗程序而言，使用高强度照明设备是常规操作。然而，即使在没有明显异常的情况下，患者暴露于高强度光能也可能造成损害。诸如手术显微镜、间接检眼镜和眼内照明器等设备所产生的辐照度足以导致视网膜损伤，使用时应有所节制，这体现了对其光毒性潜在风险的认识。
