Question

 

 

Hi,

I had a blunt trauma to the eye by a bottle cup, there was a hyphema for 7 days but still dilated.

The iris is in normal shape there is no visible tears on it but the reaction to light is poor.

After 20 days from trauma one time pilocarpine was used and the pupil shrinked to maximal small size (almost 1mm) but next day the pupil returned to previous mydriasis state.

The question is will it recover itself to normal state or its permanent?

what can I do to help it recover ?

Thanks in advance

 

Answer

 

Thanks for your Question

There are two muscles in the iris, one that constricts the pupil and one that dilates the pupil and it seems you have some sort of dysfunction to the muscle that constrictes the pupil. This muscle seems to work fine as it was constricted with pilocarpine and most likely the problem is with the innervation to this muscle.

Blunt trauma can cause damage to the nerve that supplies the iris muscles. There is nothing we can do. Just give it sometime, maybe 3-5 month and hopefully it will return to n0rmal.
