Permanently Dilated Eye

About 25 years ago, my husband was hit in the eye with a baseball.  After lots of pain and about a week later, he was able to make an appointment with an ophthalmologist.   The result of the eye injury is a permanently dilated eye.  He has been living with this over all these years and, in summary, the ophthalmologist, after examination, told him that there is nothing that can be done medically at the time and would have to live with it for the rest of his life.   He accepted the analysis; what else could he do.

His background is engineering and since then, he has been doing all the research he could do in this area.  It appears that there have been so many advances in laser technology that it appears to him that there must be a solution through surgery at this time.  

In his studies, there are six external muscles associated with the eye and that there are two intrinsic muscles; the iris and the ciliary.  As he understands it, these internal muscles control the size of the opening of the pupil.  To him, this makes the problem very difficult to attack.  

He would appreciate any information in regards to this injury and if there is any hope, please let us know.

Thank you,

The reason for the permanently dilated pupil after a blunt eye injury may be traumatic ruptures of the iris sphincter muscle.  Dr. Robert Osher in Cincinnati has written about a surgical procedure called pupillary cerclage, in which a suture is placed around the pupil to tighten it and decrease the size of the opening.  This can increase the risk of cataract, since it is an intraocular procedure, in someone who still has his natural lens in place.  A simpler alternative is a tinted contact lens, which will match the color of the other iris, and have a normal size "pupil" in the center.
