Researchers examined data gathered from more than 5,700 lung transplant sufferers in 10 Europe between 1987 and 2013. The analysis revealed that patients who lived in areas where air pollution was above maximum amounts recommended by the World Health Organization were ten % much more likely to die than those in areas with lower degrees of pollution.

Patients with dry attention may complain of a big variety of symptoms, including blurred vision, ocular discomfort, tiring, soreness, pain, burning, photophobia, itch and a gravel or sand sensation.

A hierarchical approach based on disease severity is used in the management of dry eye.
