My friend was blind for 4 minuts!

[LCSL]

My friend in home instantly became completaly blind for 3 or 4 minuts and then the vision got back completaly!  She went in the hospital and the doctor said that it was nothing and that happened because she didn't eat enough food.
Is it really grace of food or can it an eye problem or brain problem?
It happened 2 times in her life

Thanks for answering!

Here's a lesson in life, 15 year olds can have serious eye and health problems.

As the doctor said, she must see an eye MD ASAP.

Write back if you need more help.

Good luck.

Low blood sugar will not cause complete blindess and I would be reluctant to accept that as an explanation. There are some very serious causes of this including diease of the heart, brain, blood vessels and eye. I suggest she see an eye MD as soon as possible. If she is older than 50 she needs a blood test called CRP and Sed Rate to rule out giant cell arteritis.
