Dear babs42,
The laser iridotomy is usually protective of an attack of narrow angle glaucoma. Nonetheless, I would recommend that you speak with your doctor about your fears, have him examine your angles with a technique known as gonioscopy, separate dilation on two different days. He can also examine you late in the day to check your pressure.

For most people IOPs that go up to 30 are too high. Most studies would indicate you would be better off long term on drops to lower your IOP below 20. I would get a second opinion from a glaucoma specialist. Yes I know Dr Rich
