The University College of London revealed their study
findings that showed a link between air pollution and a heightened risk of
Age-Related Macular Degeneration (AMD.)
The most polluted areas tested in the study were at least
eight percent more likely to report people having AMD. The leading cause of
irreversible blindness among people over 50 in high-income countries is AMD.
The projected amount of people affected by 2040 is 300 million. Some risk
factors include old age, smoking, and genetic composition.
Brain conditions such as Alzheimer’s disease, Parkinson’s
disease, and strokes have been implicated in those who breathe poor air
conditions as well. In 2019, a study found air pollution was linked to an
elevated glaucoma risk.
Professor Paul Foster, a lead author of the UCL Institute of
Ophthalmology study, said, “Here we have identified yet another health risk
posed by air pollution, strengthening the evidence that improving the air we
breathe should be a key public health priority. Our findings suggest that
living in an area with polluted air, particularly fine particulate matter, or
combustion-related particles that come from road traffic, could contribute to
eye disease. Even relatively low exposure to air pollution appears to impact
the risk of AMD, suggesting that air pollution is an important modifiable risk
factor affecting risk of eye disease for a very large number of people.”
The research was conducted with participants who were asked
to report any formal doctor-diagnosed AMD. Structural changes in the thickness
and/or numbers of light receptors in the retina were assessed in the
participants using retinal imaging.
People in areas with high levels of fine particulate matter pollution
were higher on the AMD scale. Even after taking other factors such as
underlying health conditions and lifestyle, air pollutants (except coarse
particulates) were associated with retinal structure changes.
Though the study cannot confirm cause, as cautioned by the
researchers, their findings align with evidence found worldwide. Ambient air
pollution might be a culprit, through oxidative stress or inflammation.
Dr. Sharon Chua, of the UCL Institute of Opthamology, said,
“Higher exposure to air pollution was also associated with structural features
of AMD. This may indicate that higher levels of air pollution may cause the
cells to be more vulnerable to adverse changes and increase the risk of AMD.”
