Black hole in front of my eyes?

[Scaff]

I had just returned from a walk and went to the wardrobe to hang my coat up when I could see quite a large black hole in front of my eyes.  The area was black with bright blue centre and a yellow edge around the blue centre.  I closed one eye but it was still there, I looked away from the dark wardrobe and I cloud not see, but I then looked at the back of a black chair and it was there again.  After a short while it disappeared, after the event I felt hot and sweaty and my hands were trembling.  After a sandwich, cup of tea and a sit down everything calmed down.  I am Male and 65 yrs old.

You should not ignore this episode as it could represent what is called a TIA (transient ischemic attack) and can poor circulation or disease of the eye, heart, brain or blood vessels. It is never normal in a 65 year old nor due to low blood sugar.  You should inform your personal physician and set up an appointment for an evaluation ASAP, you also need to be seen by an Eye MD ophthalmologist. Hopefully you have one but if not you can ask your family MD to refer you.  If you have anything where all the vision goes out in the eye or you have stroke like symptoms ( slurred speech, trouble moving arms, legs, trouble with balance, etc) you need to call 911 or have someone take you to an ER immediately. There are some causes of this that are not ultra serious but the serious causes need to be ruled out first. You can read more about TIA on WebMD or emedicine.
