  • Will damage to the iris sphincter heal over time?


    Will damage from blunt trauma to the iris sphincter (resulting in mydriasis, or dilated eye) heal over time?


    It may. Only time will tell. In the meantime, if the pupil dilation is an issue due to its appearance or light sensitivity, a cosmetic contact lens can be worn to match the pupil size of your fellow eye. In some cases, pilocarpine eye drops can be used to temporarily constrict (make smaller) the pupil. If the iris sphincter muscle has been badly damaged, resulting in an irregular or large pupil, surgery can be done to decrease the pupil size.
