enlaged pupil from eye trauma
by carryles, Feb 10, 2008 03:21PM
my son was hit in the eye with a base ball 5 days ago. the cut was glued and it was noticed that the pupil was very dilated. we were told to come back in two days. the pupil was still enlarged so we were sent to an eye doctor. he put my son on drops of prednisolone every two hours. We go back tomorrow. What really concerns me is that he can not see out of the eye, everything is very blurry with large black spots. on the chart where you read the lines he can't read the top letter. they did say that the retna is not detached, but don't seem to know anything else. I was hoping someone might have some knowledge to share with me on this. thank you for your time.

The pupil may be dilated at this point due to either the trauma to the iris sphincter muscle or due to strong dilating drops that he is not taking or both. It is very common after a serious blunt injury to the eye for the pupil to be partially dilated (sometimes even permanantly.) The blurred vision could be from a corneal abrasion, a hyphema, blood in vitreous, bruising of retina (comontio retina) or other problems. If dilating drops have been prescribed - they will also make the vision quite blurred as well. Your questions are all totally appropriate good questions. Your ophthalmologist should be able to give you an idea as to the prognosis. I can't give you any help there because I don't know the extent of the injury. The main potential problem would likely be the possibility of retinal damage or just retinal swelling. Swelling will resolve - but physical damage may not. Glaucoma and cataract are also possible problems that can develop is injury is severe enough. Most cases that I have seen like this end up returning to normal except a few rare cases with severe trauma where there was a break in the retina with some permanant reduction in vision. Hopefully your son will make a complete recovery with no long term effects.

The retina did not become detached but his pupil remained dilated. He has some vision loss but we are wondering if it is permanent. A recent visit to the eye doctor showed scar tissue in the vitreous. She said this might be the cause of loss of sight. Is it possible to remove this scar tissue? Would that help restore some of his vision? Right now he has to move the eye around to a certain position to see from it.
