Mounting evidence suggests that air pollution poses a significant threat to ocular health, contributing to an increased risk of cataracts, chronic retinal disease, and dry eye. Researchers are now exploring a potential link between air pollution and corneal conditions like keratoconus.
A recent study published in Ophthalmic Epidemiology sheds new light on this connection. Building on previous research, scientists discovered that certain air pollutants can exacerbate known risk factors for keratoconus and disrupt the delicate structure of the corneal epithelium, potentially accelerating the progression of this debilitating condition. Let us take a closer look at this.
Keratoconus, a progressive eye disease, has been linked to several key factors, including UV radiation, eye rubbing, and atopy. However, researchers have also explored the potential roles of genetics, syndromes, obesity, and environmental factors.
A recent study delved into the impact of environmental pollutants on keratoconus, focusing on particulate matter (PM) and nitrogen dioxide (NO2).
New research reveals that air pollution can compromise corneal integrity through both direct and indirect pathways. Pollution disrupts the delicate balance of the tear film, leading to reduced stability and quality, while also triggering eye irritation and inflammation.
For individuals with keratoconus, exposure to air pollution may be particularly detrimental. The accumulation of reactive oxygen species in the cornea can accelerate cell death, contributing to corneal thinning. This process may not only exacerbate existing keratoconus but also potentially trigger its development in genetically susceptible individuals.
Here are some tips for keratoconus patients to manage eye health in air pollution.
● When pollution levels are hazardous, prioritize your eye health by staying indoors, especially during peak morning hours. If you must venture out:
● Wear protective eyeglasses to minimize exposure.
● Wash your hands frequently and avoid touching your eyes.
● Stay hydrated (8-10 glasses of water) to aid tear formation.
● Follow a healthy diet rich in Omega-3 fatty acids, leafy greens, and eye-friendly foods.
● Refrain from rubbing your eyes.
● Use lubricating eye drops (after consulting your ophthalmologist).
● Limit screen time and take regular breaks to avoid eye fatigue.
If eye irritation persists, consult your ophthalmologist for a comprehensive evaluation and personalized treatment plan.
While protecting vision in high pollution is a great practice for everyone, eye protection for keratoconus during high AQI is non-negotiable. Visit Laxmi Netralaya to learn more about managing keratoconus in polluted air!
