来自芬兰、瑞士及英国的报导,显示出各种类型视网膜色素变性的比率分布有明显差异。在性连隐性和常染色体隐性遗传这种差异更为显著。方法和临床人数:探讨173名视网膜色素变性病人,以确定其遗传特性百分比分布。所有病人进行了全面的眼科检查,包括用裂隙灯检查角膜、晶体和玻璃体。多数病人完成暗适应,周边视野血管荧光造影及ERG的检查。全部病人主诉有某种程度的夜盲而ERG证实了该患者的杆体和锥体的功能有异常。多数病人眼底表现有骨细胞样色素团块。
Reports from Finland, Switzerland and the United Kingdom showed significant differences in the rate distribution of various types of retinitis pigmentosa. The difference is even more pronounced between sex-linked recessive and autosomal recessive inheritance. Methods and Clinicians: 173 retinitis pigmentosa patients were explored to determine the percentage distribution of their genetic characteristics. All patients underwent a complete ophthalmic examination, including examination of the cornea, lens and vitreous with slit lamps. Most patients to complete dark adaptation, peripheral vascular fluoroscopy and ERG examination. All patients complained of some degree of night blindness and ERG confirmed that the patient’s body and cone dysfunction. The majority of patients with fundus showed osteocyte-like pigment mass.
