近二十多年来,眼科学有了较大的发展。在基础理论方面,目前国外设有专门的研究机构,从事眼胚胎、遗传、组织解剖、病理、生理、生化、微生物、药理、免疫学等方面的研究。许多新技术如电子显微镜、电子计算机、同位素标记等都被用为实验研究的手段。在临床方面,由于基础理论的进展和新技术、新器械的不断发展更新,提高了一些疑难眼病的诊断水平和治愈率。现将国外眼科主要进展介绍如下。一、基础理论方面 (一)应用电子显微镜对眼组织进行超薄显微结构的研究。 1.发现巩膜静脉窦窦壁的内皮细胞呈现空泡结构,这种内皮空泡绝大多数与前房相通,少数与巩膜静脉窦腔相通。最初的空泡形成是在滤帘组织的一面出现1个小凹
Nearly two decades, ophthalmology has a greater development. In the basic theory, there are currently specialized research institutes abroad, engaged in eye embryo, genetic, tissue anatomy, pathology, physiology, biochemistry, microbiology, pharmacology, immunology and other aspects of the study. Many new technologies such as electron microscopy, computer science, isotope labeling, etc. are used as experimental research tools. In the clinical field, due to the progress of basic theory and the continuous development and update of new technologies and new instruments, the diagnostic level and cure rate of some difficult eye diseases have been raised. Ophthalmology is now the main progress abroad are described below. First, the basic theory (A) of the use of electron microscopy of the ultra-thin microstructure of eye tissue research. 1. Found that the endothelial cells of the sinusoidal wall of the scleral sinus vacuolar structure, the vast majority of endothelial cells connected with the anterior chamber, a small number with the scleral sinus sinus chamber. The initial formation of the vacuole is a small concave in the side of the filter tissue
