矿区煤肺系采煤工人长期吸入煤粉沫,沉积在肺内致肺纤维样变性,且常伴有支气管气喘、肺气肿,使肺血循环发生原发性障碍,引起右心室肥厚。心功能衰竭是煤肺晚期主要并发症及死亡原因。本病眼部改变的研究,对病情预后的估计及诊治有重要意义。我们观察105例煤肺性肺心病眼部变化,现报告如下。 Long-term inhalation of pulverized coal mining coal mine workers pulverized coal, deposition in the lung caused by pulmonary fibrosis, and often accompanied by bronchial asthma, emphysema, the primary pulmonary blood flow disorders, causing right ventricular hypertrophy. Heart failure is the main cause of death and complications in the late stage of coal lung. The study of ocular changes in the disease, prognosis of the disease is estimated and diagnosis and treatment of great significance. We observed 105 cases of pneumoconiosis pulmonary ocular changes, are as follows.
