光色环逸散(Flight of Colors,FOC)检查是用光照射眼后出现的有色视后像变化的一种检查。据国外报道,这种检查有助于多发性硬化等脱髓鞘病的亚临床视路损害的确定,价值上可与图形反转视诱发电位结果相当。我们对FOC检查在视路各部位损害的诊断价值进行了初步观察与评价,现报告如下。 对象与方法 一、对象 共检查32例,分研究组与对照组。研究组为疑有视路损害的病人11例,包括多发性硬化1例,视神经脊髓炎2例,球后视神经炎2例,脊髓炎2例,交感性眼炎1例,脑梗塞累及有视路病变2例,视网膜中央动脉
The Flight of Colors (FOC) test is a test that examines the appearance of a colored visual image as a result of light exposure to the eye. According to foreign reports, this test is helpful for the determination of subclinical visual impairment of demyelinating diseases such as multiple sclerosis, and may be comparable in value to the reversal of visual evoked potentials. We conducted a preliminary observation and evaluation of the diagnostic value of FOC examination in all parts of the visual pathway, the report is as follows. Objects and methods First, the object were examined in 32 cases, sub-study group and control group. The study group was suspected to have pathological lesions in 11 patients, including multiple sclerosis in 1 case, 2 cases of optic neuromyelitis, 2 cases of retrobulbar neuritis in 2 cases, 2 cases of myelitis, sympathetic ophthalmia in 1 case, involving cerebral infarction Pathological changes in 2 cases, the central retinal artery
