A new study from the University of Colorado Anschutz Medical Campus reveals that air pollution, specifically particulate matter (PM), is associated with a significant increase in clinical visits for ocular surface conditions like eye irritation and allergic conjunctivitis. Published in Clinical Ophthalmology, the study found that patient visits for these conditions more than doubled when PM10 levels reached 110 micrograms per cubic meter.

Eye Conditions Examined in Denver

Researchers analyzed over 144,000 outpatient visits in Denver, linking air pollution to eye health issues. Conjunctivitis accounted for one-third of all visits, reflecting a global rise in allergic eye diseases potentially driven by environmental factors like temperature, humidity, and pollution.

Broader Impacts of Climate Change on Health

Lead author Jennifer Patnaik highlighted the broader health risks of climate change and air pollution, noting their links to infectious diseases, respiratory and cardiovascular conditions, and less-studied chronic diseases like dementia.

Expanding Research on Air Pollution and Eye Health

Senior author Malik Kahook emphasized the need for further research on air pollutants’ impact on eye health. The team aims to expand their research geographically and develop preventive strategies and treatments, particularly for vulnerable populations in highly polluted areas.

Addressing Systemic Health Impacts of Climate Stressors

This work underscores the systemic health effects of climate-related stressors, including air quality, wildfires, temperature, and drought. The researchers advocate for transdisciplinary studies to address these challenges and improve public health outcomes.
