                        My son had this and we had no idea how seriosu it is, but it is a secondary condition to spondylarthropathy.  Besides the drops he has been put on Vioxx.  You should have a blood test and a genetic marker done HBL-B27 to see if you are positive.  You may find that you have an underlying cause for the iritis.  Hope it gets better
