Understanding Eye Stroke Caused By Extreme Heat, Risks And Prevention

As Delhi endures an intense heatwave, with temperatures soaring to a record 52.9 degrees Celsius in Mungeshpur, health concerns have risen, particularly about the risk of an eye stroke from direct sun exposure. One person has already succumbed to heatstroke in the capital, highlighting the severe impacts of the extreme weather.

What is an Eye Stroke?

An eye stroke, medically known as anterior ischemic optic neuropathy, occurs due to insufficient blood flow to the optic nerve’s front tissues, according to Penn Medicine. If the blockage affects blood vessels extending from the optic nerve to the retina, it is termed a central or branch retinal artery occlusion. This condition can cause sudden vision loss and is potentially debilitating.

Heat’s Impact on Eye Health Heatwaves can detrimentally affect eye health by causing dehydration, leading to dry eyes and irritation. Increased exposure to harmful ultraviolet (UV) rays during extreme heat can damage the eyes, heightening the risk of conditions like cataracts and macular degeneration. High temperatures can also exacerbate allergies, making individuals more prone to eye infections and irritation from frequent eye rubbing.

Symptoms of Eye Stroke

Key symptoms of an eye stroke include:

• Dryness in the eyes
• Constant irritation
• Blurry vision
• Conjunctivitis
• Swelling
• Sudden vision loss in one eye
• Loss of visual contrast or light sensitivity

Tips to Stay Safe To protect your eyes during extreme heat, consider the following precautions:

• Wear sunglasses that block UV rays to prevent cataracts, macular degeneration, and other eye damage.
• Stay hydrated by drinking at least eight glasses of water daily, more if spending time in the heat.
• Use UV-blocking contact lenses for additional protection against UV rays.
• Eat eye-healthy foods rich in omega-3 fatty acids, vitamins C and E, and zinc to support overall eye health and reduce heat and UV exposure risks.
• Wear a hat when outdoors to reduce direct sunlight exposure to the eyes.

By taking these preventive measures, individuals can safeguard their eye health and mitigate the risks associated with extreme heat conditions.
