I heard that they can detect diabetes by dialating the eyes...

1: Yes, though it's quite possible to detect diseases without dilating them. Dilating gives a better view of the periphery of the back of the eye and is necessary to use certain types of ophthalmoscopes and cameras.
Anything from brain tumours to kidney disease may show signs in the eye, as well as diseases specific to the eye: cataract, glaucoma, macular degeneration... the list is quite long.
2: Yes. Though it's not a very efficient way of detecting diabetes* I have done it many times. Sometimes because it has been present undetected for a good while the first sign is retinopathy: blood vessel damage at the back of the eye. More commonly, it is noticed that the vision is varying when the person reports that they can't see with their new glasses, and it is found that the prescription has changed within a day. Once the optometrist making a mistake has been eliminated as a possibility, type II diabetes may well be the next suspect.

* it could have been detected much earlier with a blood or urine test, if it has reached a stage where it is affecting the eyes. But sometimes that hasn't happened.

Yes, I am an optometrist myself. We dilate the eyes in order to check the back of your eye where many disease can occur. No, however, some of my collegues in school were talking about that rumor.

No, you need some blood testing for that but they can detect pressure in the eye or behind the eye.

Imitrex is an somewhat sensible drug for many human beings. basically as a results of fact it does not artwork for you does no longer recommend that your clinical professional is dealing with this badly. call your clinical professional's place of work and tell them that the Imitrex isn't working. There are different techniques. in case you choose to make certain a neurologist, you gets the comparable answer: initiate with imitrex, and if it does not artwork, we will stumble on different techniques.
