白内障是眼科常见性疾病,特别是对老年人的生活质量有很大影响。在人的眼内有一重要的器官叫晶状体,它在正常情况下是透明和富于弹性的。晶状体就像照相机的镜头一样,通过它的聚光作用能使人看远、近东西都清楚。如晶状体出现浑浊,以至影响视力,即成为白内障。白内障的病因尚不清楚,大多数起因于年龄增长,少数原因是眼外伤或某种眼病之后以及某种毒物或放射线作用于眼的结果。也有先天生下来就患白内障的。白内障一般发病年龄在40岁以上,晶状体本身逐渐变性混浊,一般为双眼。但双眼发病的时间,混浊的程度会不同,有先有后。无论全身疾病或眼局部病变引起的白内障都属于并发性白内障的范围。并发性白内障发生的原因相当复杂。糖尿病病人由于长时间的血糖增高,造成身体代谢障碍,引起全身一系列的并发病症,白内障就是其中之一。 Cataract is a common ophthalmological disease, especially for the quality of life of the elderly. In the human eye there is an important organ called the lens, which is normally transparent and elastic. The lens, like the camera’s lens, can make people look far and wide through its condenser effect. Such as the lens appeared cloudy, and even affect vision, which has become cataracts. The etiology of cataract is unclear, mostly due to age, and a small number of causes are the result of ocular trauma or some eye disease and the effect of some poisons or radiation on the eye. Also born born cataract born. The general incidence of cataract over 40 years of age, the lens itself gradually degenerative opacity, usually for the eyes. However, the time of onset of both eyes, the degree of turbidity will be different, there are prior. No matter systemic diseases or eye diseases caused by cataracts belong to the scope of concurrent cataracts. The causes of complicated cataracts are quite complex. Cataract is one of the patients with diabetes due to prolonged blood sugar increase, resulting in metabolic disorders in the body, causing a series of concurrent systemic diseases.
