According to the British Journal of Ophthalmology’s observational study one’s vision might also get affected by air pollution. A condition called age-related macular degeneration (AMD) might develop due to poor air quality.
The age related condition affects the center of the vision- Macula. Dr. Vaidehi S. Dedania, a retinal surgeon at the NYU Langone Eye Center and assistant professor in the department of ophthalmology at NYU Grossman School of Medicine, informed that in people over the age of 50 AMD is the third-leading cause of vision loss worldwide.
According to the World Health Organization (WHO), even when there have been major gains in combating air pollution in recent times still ninety one percent of the world’s population is living in spaces with the quality levels of air exceeding the limits. Nearly 4.2 million people die every year due to air pollution by getting stroke, heart disease, lung cancer, and chronic respiratory diseases.
Dr. Vaidehi S. Dedania says that the individuals can experience loss of vision in the advanced stages of disease. This could result in severe and permanent visual impairment. AMD can be nonexudative (i.e. dry) and exudative (i.e. wet). Out of the two, dry AMD is more common. Both cause severe vision loss but most severe vision loss occurs in people with the wet form of the disease in AMD.
The study began in 2006 and since then researchers have studied data from 115,954 UK Biobank studies with participants of 40 to 69 years of age.They had no eye problems when the study began and they were asked to report if they received a formal diagnosis of AMD by their doctor.
