The Yangtze River Daily Da Wuhan Client July 21 (Reporter Wuye Correspondent Zhang Quanlu) "I came to cure tuberculosis, why should I check my eyes?" Last week, a patient with tuberculosis went to Wuhan Pulmonary Hospital for review. One of the "vision inspections" puzzled. However, the doctor found that the patient's vision defect was found in this examination. After timely adjusting the medication, the risk of blindness was avoided.

Ms. Xie from Hongshan District is currently taking anti -tuberculosis drugs for treatment. A week ago, when she came to Wuhan Lung Department to review, the "vision inspection" made her a little puzzled. "I'm here to cure tuberculosis. Why do I have to check my eyes every time I review? If my eyes are not good, I feel that I still need to detect it?" Ms. Xie expressed this doubt.

Ke Qihai, a physician of the Department of Functional Department of Wuhan Pulmonary Hospital, said that this is a necessary examination for monitoring the side reactions that the drug may bring. Because commonly used anti -tuberculosis drugs such as ethylene glycol and Lenitorazolid, although the application in most people is safe, for a small number of people, it is possible to cause vision damage. Visiting field damage, if it is not found and adjusted in time, the damage may be irreversible, and it may cause blindness in severe cases.

During the vision examination, the patient faces a hemisphere instrument, and it is like facing a vast sky in front of him. At this time, a star -like highlight flashed in the "sky", and it disappeared instantly, and then a bright spot flashed from elsewhere, and then disappeared, so repeated. The patient found a highlight, and pressed the controller once.

The results of Ms. Xie's field of vision show that her vision center has reduced vision sensitivity in multiple adjacent areas, that is, her vision has suffered damage. After eliminating other factors, it can be determined that the tuberculosis drugs have the side effects of damaging the optic nerve on her.

Ke Qihai said that if Ms. Xie did not check her vision in accordance with the doctor's advice, this situation could not be discovered with the patient's subjective feeling, then her vision will suffer irreversible losses unknowingly, which is seriously blind.

Ke Qihai immediately feedback this result to Ms. Xie's attending doctor, and the doctor quickly adjusted the medication. This week Ms. Xie reviewed again that the side effects of the drug had been eliminated, and the damaged vision was gradually recovering.

Ke Qihai said that he had to do a vision examination for a large number of patients every day. He always heard the patient complaining that the test was "redundant", so when operating the handle, some patients often cope with things, and he had to explain patiently every time. In fact, after a year, Ke Qihai can always find a few patients like Ms. Xie, such as Ms. Xie, who have already had visual damage. After timely communication and disposal of Ke Qihai with the doctor, they avoid the risk of blindness.

At present, some tuberculosis drugs have irreplaceable therapeutic effects, so they cannot be abandoned for the time being. From the perspective of prevention, any drugs may have side effects. For patients with tuberculosis, you only need to follow the doctor's advice to pass the regular vision examination to monitor the side effects of the drug. The first time you find the drug optic nerve damage, the doctor can be eliminated quickly after adjusting the medication.
