Question: Why do we dilate eyes with internal inflammation?

Answer: When the iris becomes inflammed, such as from trauma, uveitis, or infection, it becomes “sticky” and likes to adhere to nearby structures. The iris can stick down to the underlying lens which can become a problem if 360 degrees as this creates an iris bombe glaucoma. it can also adhere to the cornea at the limbus, which can in turn affect aqueous outflow through the angle.

A cycloplegic can make the patient more comfortable, as this will paralyze the iris/ciliary body and keep them from spasming with bright lights. Also, a short or medium acting cycloplegic can help keep the iris moving, so that it doesn’t form synechae or breaks the ones that are forming to nearby structures.

My name is David Scott and one week ago I had an eye injury playing tennis. I was attempting to return a canon of a serve and the ball skewed off my racket and beaned me right in the left eye actually not even touching any orbital bones. The immediate reaction was very intense pain and I was literally on my knees. I got a pack of ice from the high school trainer on site and applyed the ice for about an hour. My eye continued to hurt and the pain has subsided since. I saw an opthamologist the next day and he did not see any internal/ecternal bleeding and said the retina appears smollen. The problem I have now is my eye is still somewhat blurry ( close object appear larger and closer up than reality and my pupil will not constrict back to the way it should like my right eye ). What is your take on this?? Do you think fluid may have leaked in my eye??? Do you have a time frame hopw long this may take to heal??

I got hit in the eye by a small object that shot out of the lawn mower. I had stitches next to my iris and a blood glotover the eye, Subsiquently I had my eye cleaned out and the lens taken out two weeks later. Its been almost three months now with out a lens because I have a swelling around the optic nerve that the doctor is waiting to heal before they put a lens in my eye.

Do you recomend any eye exercises to help healing or do I just wait and hope that the swelling goes down?

Thank you Bran Collingwood
