Hello from JA
I am Dr. Thomas, board certified in internal medicine and integrative medicine and I can help you with this and any follow up questions. I cover a lot of ground and might give you an answer or ask for information, but use reply to communicate with me for questions or added details.
There are a number of things that can cause a dot.
Sometimes it is simply a small old scar from a fungus called histoplasmosis, which does not cause harm.
Diabetes and hypertension are the prime things to rule out.
This is not cancer if that is what you are thinking.
It does not sound ominous at this point, but I would see an MD/opthalmologist, not really on an optician. They don't have the training to differentiate this situation.
OK. If you have further questions or details, use reply to expert.
Otherwise please choose a positive rating . But, still come back if you need to…think of something later, etc. Bonuses are appreciated.
