Does Beijing’s Smog Lead to Increased Respiratory Diseases?

The composition of smog is very complex, including hundreds of types of atmospheric chemical particles. The main harmful components to health are the aerosol particles with diameters less than 10 micrometers, which can directly enter and adhere to the human respiratory tract and alveoli. Long-term exposure to this environment may trigger lung cancer. For patients with chronic respiratory diseases such as asthma, chronic bronchitis, obstructive pulmonary emphysema, and chronic obstructive pulmonary disease, smoggy weather can cause acute exacerbation or acute worsening of the condition.

Does Blindness After Glaucoma Surgery Require Another Operation?

My father had a glaucoma surgery at the Northern Hospital over 20 years ago and is now 69 years old. He has only one eye with a vision of 0.25, and the other eye is completely blind. The eye that had the surgery recently measured normal intraocular pressure on November 12th, with vision still at 0.25. Now, during the day, he seems to see things with a foggy sensation, is sensitive to light, and takes several minutes to recover vision when entering a dark place. Sometimes his eyes briefly turn white before returning to normal. Do I need another surgery? If not, what medications can improve vision clarity and control the disease from worsening? Will not undergoing surgery lead to complete blindness? Thank you for your response.
