08 Jun Marathon runner FROZE his eye after racing
A marathon runner temporarily lost sight in one eye when it froze as he was jogging in poor, cold weather. The 44-year-old man suffered from ‘wind-blindness’ – a condition in which the wind dries out the protective layer of tears covering the eye. This allows snow and hail to get into the eye, freezing its outer layer.
People do not blink as much in cold weather, meaning the eye isn’t thawed out with fresh tears.
The man came to a medical checkpoint at the end of the first stage of a marathon complaining of a sore left eye, cloudy vision and the feeling of having something in his eye.
Describing his case in the British Medical Journal case reports, doctors discovered he had frozen his left cornea, the clear outer layer at the front of the eyeball.
This led to scratches known as abrasions developing on the surface.
Parts of his left eye were swollen and his lens was visibly cloudy, doctors noted.
The medics immediately pulled the man out of the poor weather conditions until his the swelling went down and his vision recovered.
Any further cold and wind damage to his eye could have cause ulceration of the cornea, which can threaten vision if left untreated, they said.
There was intermittent hair and snow the day the man was running, with temperatures plunging from below 5°C to below zero.
Doctors warn marathon runners to wear goggles to protect their eyes while racing in poor weather conditions
