Hi. I'm online and happy to answer your question today.
The air puff test, mostly used by optometrists, is not that great of a way to check eye pressure. Goldman applination tonometry is the best way to do that.
But to answer your question: Normal eye pressure is between 10 and 21.
Glaucoma progresses at different rates in every patient....there are many, many factors that determine how quickly and how severe glaucoma is. If capillaries have burst and your brother is having light sensitivity along with elevated eye pressure he really needs to see an ophthalmologist and not an optometrist for his eye care
There is a lot more to the diagnosis of glaucoma then just eye pressure. A full exam of the health of the optic nerve, changes in visual fields, morphology of the angles of the eye (outflow channels) etc all are taken into account when diagnosing and treating this blinding disease. With his very strong family history of glaucoma and the problems he is having with his eyes I feel strongly that he should see an ophthalmologist and, should he desire, possibly a glaucoma specialist.
Does this make sense to you?
