外层视网膜病变并不特指某一种视网膜疾病，具有此类病变的患者通常有视觉异常的症状，但是传统常规眼科检查难以发现阳性体征，所以常常被冠以“隐匿性”病变的标签。近年来光相干断层扫描（OCT）技术在临床上得到广泛应用，发现不少所谓“隐匿性”疾病实为外层视网膜结构异常所致。造成结构异常的病因多种多样，治疗手段及疾病转归也各不相同，所以临床眼科医师需要详细询问病史，结合多模式影像对其进行诊断和鉴别诊断，而不是笼统地诊断为“外层视网膜病变”。相信随着OCT影像技术的发展，通过更高清影像揭示出视网膜组织更细微结构，可以让我们对疾病有更深入地理解和认识，进而提高其临床诊疗水平。“,”Outer retinopathy does not refer to a specific type of retinal disease. Patients with outer retinopathy often have abnormal vision symptoms, however, no positive signs can be found with conventional routine eye examination. And the diseases are often labeled “occult” . In recent years, optical coherence tomography (OCT) has been widely used in clinical practice. It has been found that many so-called “occult” diseases are actually caused by structural abnormalities of the outer retina. The causes of structural abnormalities are diverse, and the treatments and disease outcomes are also different. Therefore, it is necessary for clinical ophthalmologists to get detailed medical history, make diagnosis and differential diagnosis based on multi-model imaging, rather than roughly name it as “outer retinopathy” . With the development of OCT imaging technology, higher resolution images reveal the finer structure of retinal tissue, allowing us to have a deep understanding of the disease, thus improving diagnosis and treatment in clinical practice.
