Medical Forum / General / Vision / July 2007Could miotic eyedrops be used to treat myopia in conjuction w/ minus lenses?
Could miotic eyedrops be used to treat myopia in conjunction w/ minus lenses? Pinhole glasses increase depth of field and reduce the circle of confusion on the retina, thus stopping down the iris' aperture and slowing down the eye's lens speed; miotic eyedrops would basically be chemical pinhole glasses. At the very least it would lessen the power of the eyeglasses or contacts needed. What do you guys think? >Could miotic eyedrops be used to treat myopia in conjunction w/ minus >lenses?

Atropine is a MYDRIATIC; it dilates your eyes --for about two weeks--. >> On Mon, 16 Jul 2007 20:24:43 -0000, DarkProtoman >> [quoted text clipped - 9 lines] > >Atropine is a MYDRIATIC; it dilates your eyes --for about two weeks--. Ayup, but it has a proven track record of slowing myopia progression. Never heard of any such thing with a miotic. Doesn't mean it can't be so, but.... They could, but why bother? They have some pretty horrible side effects (headache, dim vision, night blindness, etc.), and they could theoretically even cause an increase in myopia due to concurrent and prolonged accommodative stimulation. First do no harm. w.stacy, o.d. >Could miotic eyedrops be used to treat myopia in conjunction w/ minus >lenses?

Atropine, OTOH, is well known to slow the progress of myopia. -MT > > Could miotic eyedrops be used to treat myopia in conjunction w/ minus > > lenses?

Hertzog's my opthalmologist; http://hertzogeyecare.com/index.htm--, performed my optometric eye exam --I had to then see Dr. Hertzog for an opthalmologic eye exam, b/c I have grade II ROP; he told me I have a very tiny cataract in both eyes-- he used pinhole glasses, and I could see the chart better; not as well as w/ my eyeglasses, but better than w/o them. So they must work. BTW, have any of you had experience w/ Drs. Hertzog and/or Ryan? How do you like them? > he used pinhole glasses, and I > could see the chart better; not as well as w/ my eyeglasses, but > better than w/o them. So they must work. Of course they "work". But your myopia is still there. -MT And you say that Atropine has no side effects? > > Could miotic eyedrops be used to treat myopia in conjunction w/ minus > > lenses?

Are you off the meds again? Didn't they warn you about that??

So then, Atropine has a serious secondary effect? "First do no harm".

Sure. Everything has side effects. But individuals treated with atropine do better than untreated controls. Individuals treated with plus lenses don't show the same long-term benefits. If they did, Ong and Parssinen and Shotwell and all those others would have reported it. They lied? Atropine blurs vision, plus lenses blur vision. Atropine works but it's too noxious. Plus lenses are noxious too, but so far they have failed to demonstrate long-term benefits. Still waiting. -MT >So then, Atropine has a serious secondary effect? > >"First do no harm". Yeah. That's part of the oath that you never HAD to take. Maybe that explains why your (absent) conscience isn't plagued by the people in whom you've induced double vision. God, but you're an idiot. > Could miotic eyedrops be used to treat myopia in conjunction w/ minus > lenses?

Leaving aside the drop side effects, there is no evidence that pinhole glasses slow or reverse myopia. Dr Judy |
