老年性白内障是最常见的致盲眼病。此病悄悄地发生,默默地进行,除了发生并发症外,患者无任何痛痒感,仅视力呈进行性减退,直至完全失明。视力减退的直接原因,是原来透明的晶体逐渐变得混浊,减弱或阻止了视网膜对外界景物的感受能力,造成患者视力减退或失明。防治的关键就是如何处置这块起透光作用的晶体。 Senile cataract is the most common cause of blindness. The disease occurred quietly, silently, in addition to complications, the patient without any sense of itching, visual acuity was progressive decline until completely blind. The direct cause of vision loss is that the original transparent crystal gradually becomes cloudy, weakening or blocking the ability of the retina to feel on the outside world, resulting in patients with vision loss or blindness. Prevention is the key to how to deal with this piece of crystal from the role of transparency.
