Glaucoma Eye

My ophthalmologist is not eye dilation before the test eye pressure glaucoma (breath of use the machine). Is the expansion of distorting the reading test for glaucoma?

He can do - as dilated iris can slightly reduce the flow of aqueous fluid from the eye.

But in a way that you want the highest reading you can manage - if you're at risk for angle closure, the pressure may be higher and would highlight this fact. If you only measured the pressure before the expansion, then you do not have any information on what happens to the pressure sometimes - though rarely.

But I measured the IOP of thousands of times - both before and after the expansion (of the same person), and rarely see a difference - and if you use the type of cloud tonomoeter the factor of error is probably larger than this variation.

So, in conclusion, it is not really important.

No, that's fine.
