Patient: I have been suffering from eye disease for more than 10 years, and my left eye is blind. I am worried that my right eye will also go blind, so I would like to ask you to help me diagnose and treat it. Thank you! Liu Yi, Department of Ophthalmology, Beijing Tongren Hospital: Since I haven’t seen the patient, I can’t “confirm” the diagnosis, but you can have a local optometric examination first to see if you can improve your vision by adjusting your eyes. If you have a cataract, with or without macular problems, you can consider surgery, but the improvement of vision after surgery is not very obvious, and cautious doctors are generally not willing to do it.
