The extreme heat can affect overall health, increasing the risk of heart diseases, brain disorders, and other organ issues.
As heatwaves sweep across various regions, there has been a noticeable increase in eye stroke cases. This condition, also known as retinal artery occlusion, can cause sudden vision loss and is comparable to a brain stroke in its seriousness.
Impact of heatwaves on eye health
The extreme heat can affect overall health, increasing the risk of heart diseases, brain disorders, and other organ issues. Notably, it can also lead to eye strokes due to dehydration and heightened blood pressure. Dehydration during hot weather makes the blood more prone to clotting, while high temperatures can exacerbate cardiovascular problems, raising the risk of arterial blockages.
Eye stroke
An eye stroke occurs when blood flow to the retina is obstructed, depriving it of oxygen and nutrients. This can cause severe retinal damage in minutes. Dehydration from heatwaves thickens the blood, making clots more likely, while heat stress can worsen cardiovascular conditions, further increasing eye stroke risk.
Signs and symptoms
Sudden Vision Loss: The most common symptom, this can be partial or complete, and typically painless.
Visual Disturbances: Sudden dimming or blurring of vision, where central vision is affected but peripheral vision remains intact.
Preventive measures
Stay Hydrated: Ensure adequate fluid intake to prevent dehydration.
Avoid Peak Sun Hours: Limit exposure to the sun during the hottest parts of the day.
Manage Chronic Conditions: Keep blood pressure and other chronic conditions under control.
TImmediate Medical Attentioreatment optionsn: Urgency is crucial as delays can lead to permanent vision loss.
