you need an eye exam. there are 2 scenarios i can think of off the top of my head, both of them need further investigation.
one is called UTHOFF's sign. its blurry vision with heat...that would be a possible diagnosis of MS.
the other would be a form of glaucoma called "plateau iris".
you need an eye exam with careful pupil testing, color vision testing and a visual field. you also probably need a neuro evaluation.
hopefully i'm wrong and you're fine, but blurry vision ONLY when you get hot or exercise...i consider that certainly worth investigating.
Thank you for your reply.
The problem I have is I am working in a very remote part of the world and will get it checked out on my return to the UK.
I have been told that I may have a lump behind my eye (apparently common ?) and may need to have it removed. Make any sense?
a lump "behind your eye"?
...no i would NOT consider that common. on yor face or your eyelids, maybe. but not "behind" your eye.
Could you have misheard? Could it be a mole behind your eye? I have one of those, and I gather that they're not really so uncommon. My eye doctor just looks at it whenever I go in for a regular checkup, and it's never changed, so we don't worry about it.
MLWTR: i didnt think of that...a "nevus" or retinal "freckle"...yes, that is common...
maybe by "lump behind the eye" they were talking about a hemangioma or something like that...
an MRI scan and a consultation with a neurologist...i would suggest that
