Effects of environment pollution on the ocular surface

Area of Science:

• Environmental Science
• Ophthalmology
• Public Health

Background:

• 21st-century environmental hazards like climate change and pollution pose significant risks to human health.
• While respiratory and cardiovascular impacts are well-documented, ocular surface complaints linked to pollution are less understood.
• Pollutants include traffic-derived gases (ozone, NO2) and particulate matter, as well as indoor environmental hazards.

Purpose of the Study:

• To explore the impact of environmental pollution on ocular health.
• To understand the mechanisms by which pollutants affect the eye.
• To identify challenges in assessing pollution's effects and highlight the need for protective measures.

Main Methods:

• Review of existing literature on air pollution and ocular surface disease.
• Discussion of pollutant sources and their varied nature (gaseous, particulate).
• Exploration of pathogenic mechanisms including toxicity, oxidative stress, and inflammation.

Main Results:

• Pollution exposure can lead to symptoms like eye irritation, redness, foreign body sensation, tearing, and blurred vision.
• Ocular surface disease mechanisms involve toxicity, oxidative stress, and inflammation.
• Individuals with allergic or atopic tendencies may be more susceptible to environmental triggers.

Conclusions:

• Environmental pollution presents a growing threat to ocular health, necessitating further research and intervention.
• Identifying susceptible populations and implementing protective or therapeutic strategies are essential.
• Advancements in pollutant monitoring and eye assessment technologies are vital for progress in this field.
