Retinal nerve change in dominant eye?

[sbwaters]

Been shooting skeet for about three summers with a 12 gauge Remington 1100.

Eye doctor is noticing some retinal nerve change in dominant eye that could be beginning of glaucoma but the pressure is consistently normal. Dr. says it could be because I’m very near-sighted.

I’m curious. Do others have nerve irregularities in their dominant shotgun shooting eye?

My Remington 1100 has a sporting stock which means that because of the stock drop, my cheekbone gets about 75 jolts a week. I shouldered a B-Fast Beretta Silver Pigeon I the other day and noticed how sweetly parallel it was when I shouldered the thing. Firing it would have spared my eye of repeated jolts.

I couldn’t find anything on a quick search online. Your thoughts?

What specific changes is he seeing? Usually trauma-induced damage will be neovascularization; broken blood vessels, which will collect blood in them until they repair themselves. this can increase pressure on the optic nerve, but it will usually clear up. Or it's floaters, which is detached groups of epithelial cells from the retina floating around in the vitreous humor. They are normal in small amounts and small sizes, but if more and bigger chunks start coming off, time to visit your ophthalmologist. It's possible to have a retinal detachment from shooting, but not common, and he'd see that right away.

Is he seeing high tonometer readings? Those alone are not an indication of glaucoma. I have pressures over 22 Hg, normal is 15-16. The "cupping" (the way the OD I work with described it) of the optic nerve, along with higher readings, is a probable sign of the early stages of glaucoma, but high readings alone isn't.

High myopia (nearsightedness, which I also have) can complicate attempting a glaucoma diagnosis, because the eye ball is longer than normal. I will ask Doc about the possibility of shooting a 12 ga. causing changes, He and I both shoot, so it should be an interesting conversation.

Three tests for glaucoma:
1) Pressure: normal
2) Visual pattern: excellent
3) Changes in how retinal nerve looks: Beginning symptoms for glaucoma.

So it doesn’t seem to be glaucoma ... and that raised my curiosity about other things that had changed over the last few years.

BTW: I’m almost 70, wear soft contacts w/ vision corrected to 20/20.

Yes, usually all three, or two of the three and a family history of it, are needed for a diagnosis of glaucoma. Glad to hear your vision is good!

beginning of glaucoma

I was told this about 2 month ago. Was told the test result could be normal for me, as each person is different.
Will return in 6 month for the same test, to see if pressure or what ever has changed.

Age 72. I mostly need my glasses to see far away. I see close and read with or without the bifocals.
