本文对7例正常人眼前房角小梁网及47例原发性开角青光眼的小梁切除标本进行了组织化学——酸性粘多糖(Acid mucopolysaccharides简称AMP)及超微结构的研究。正常人年龄为20～70岁,病人年龄为17～70岁。按不同年龄分为三组:17～29岁20例、30～39岁14例、≥40岁13例,其中39岁以下病人34例。研究结果证实,在正常人眼小梁网中存在酸性粘多糖,主要分布在内皮网部, In this paper, seven cases of normal human anterior chamber angle trabecular meshwork and 47 cases of primary open-angle glaucoma trabecular meshwork were studied by histochemical-acid mucopolysaccharides (AMP) and ultrastructure. Normal age is 20 to 70 years old, the patient’s age is 17 to 70 years old. Divided into three groups according to different ages: 17 to 29 years in 20 cases, 30 to 39 years in 14 cases, ≥ 40 years in 13 cases, of which 34 cases of patients under 39 years of age. The results of the study confirm that there are acidic mucopolysaccharides in the normal human trabecular meshwork, which are mainly distributed in the endothelium,
