Although, thanks to the Brock string, I can now point both eyes at the same spot in space, there is always a problem regarding fusion: the lines of what each eye sees do not run parallel to the ones of the other eye. In other words, the image of one eye is slightly tilted in relation to the image of the other eye.
I think this is the result of eye surgery. I try to correct it through exercises but I've never felt any improvement except for one time, a long time ago (with other areas of the my sight I noticed improvements every week).
Does anyone know this problem? Is it possible to correct it? Is there any particular exercise you might recommend?
Many thanks in advance.
Sound like you are talking about an eye rotation called Cyclorotation. Or if an eye is actually rotated compared to the other it is a cyclophoria or cyclotropia. I have seen patients with cyclo improvement as the lock to bring the two images into one becomes stronger. I have also seen it be the last thing that remains after VT.
With any visual pathway deviation up ,down, right, or left or any one direction we can use prisms to help "finish" the two eye coordination fusion process. Unfortunately we do not have a lens that fixes or compensates for a rotational component.
I also have, what's seems to me an eye tilt. My view from my right eye is tilted downward and toward the right. I have been able to reduce this, I think, using loose prisms. For example, I'll look at a bead on the Brock string, and the string image seen by the right eye appears slightly titled. Then I'll place a loose prism in front of my eye, angling the prism so it makes the tilt worse. Then I look down the Brock string and work against the tilt produced by the prism. I can use different strength prisms and different tilts of the prism to make the exercise more or less challenging.
Very interesting replies!
Robert, I had never heard about cyclorotation as such. It's a pity that there isn't a specific treatment for it, but I'm glad to know improvements with it are known to exist.
Sue, considering that you are our primary influence, it's cool to hear we share the "tilt" problem. I will definetely use prisms in the way you describe, I'm very interested in giving it a try.
Thank you both very much.
I´ve jus arrived to this forum I´ve seen you´re a really active member on it.
As we both are from Madrid, I´d be very interested in get in touch with you and share some experiences related with our problem.
I´ve sent you a friend request!
