定义
原发性开角型青光眼是一种慢性进行性视神经病变,在没有其他眼部疾病或先天性异常的情况下,视神经头和视网膜神经纤维层发生特征性形态学改变。进行性视网膜神经节细胞死亡和视野缺损与这些改变有关。前房角外观正常,主要危险因素包括眼压水平和年龄较大。
Primary open-angle glaucoma is a chronic progressive optic neuropathy with characteristic morphological changes at the optic nerve head and retinal nerve fibre layer in the absence of other ocular disease or congenital anomalies. Progressive retinal ganglion cell death and visual field loss are associated with these changes. Anterior chamber angle appearance is normal and major risk factors include level of intraocular pressure and older age.

后组配是在主干编码之后追加的可选扩展轴(如侧别、具体解剖部位、严重程度),用于把「部位 + 侧别 + 病程」等细节一次表达完整。只有标注「必填」的轴在组合编码时必须给出,其余可留空。
