Tuberculosis drugs generally do not cause eye blindness, but some patients taking anti-tuberculosis drugs may cause the patient’s vision abnormalities, which requires prompt medical attention. Patients with tuberculosis need to take anti-tuberculosis drugs under the guidance of a doctor for systematic and regular treatment. In taking anti-tuberculosis drugs, there may be adverse drug reactions, for example, it will lead to liver function damage, optic nerve damage. Some of the anti-tuberculosis drugs, such as ethambutol, may cause changes in vision, such as blurred vision and narrowed field of vision, but generally do not cause blindness. Patients using ethambutol or clofazimine should have their visual acuity and red-green discrimination monitored once a month. Patients with tuberculosis who experience symptoms of blindness need to seek medical attention to rule out problems with the eye itself, such as corneal ulcers, dry eye, etc. When taking anti-tuberculosis drugs, if there is any abnormality, you should communicate with your doctor in time, and the doctor will guide you to use the drugs.
