白内障是一种常见的眼科疾病,占致盲病的首位。现,常规用裂隙灯显微镜进行观察检查。由于只能定性观察,因此不能区別白内障病变的严重程度,特别是在白內障的整个发病的演变过程中,或采用药物治疗期间,无法作定量的记录,只能通过病人及医生的主观感觉来评判。故难以探索其发病机理及疗效观察,并不能长期存档保存,因此对白內障进行定量的检测是十分必要的。国际上,日本等国家在此方面做了些研制工作,日本的产品采用照相后测定密度的方法等,操作复杂,价格昂贵。国內亦有报导。目前,国内要求对白内障病变进行定量测定的呼声越来越高。我们在参考了国内外资料的基础上,开始研制。并取得样机进行临床检查。 Cataract is a common ophthalmological disease, accounting for the first cause of blind disease. Now, the conventional slit lamp microscope for inspection. Because only qualitative observation can not discriminate the severity of cataract disease, especially in the evolution of the entire incidence of cataracts, or during medication, can not be recorded quantitatively, can only be judged by the subjective sense of the patient and the doctor . It is difficult to explore its pathogenesis and efficacy of observation, and can not be preserved for a long time, so the quantitative detection of cataracts is very necessary. Internationally, Japan and other countries have done some research in this regard. Japanese products adopt the method of measuring the density after photographing, and the operation is complicated and expensive. There are also reports in China. At present, the domestic demands for quantitative determination of cataract lesions are getting louder and louder. We have made reference to the domestic and foreign materials, based on the start of development. And to obtain a prototype for clinical examination.
