Dealing with reccurent severe bouts of anterior uveitis for 6 years, any ideas?

i've had horrible cases of iritis for about 6 years now in both eyes. i've had tons of bloodwork and testing (chest x-rays, coloonscopy, endoscopy), and the onyl thing ever found was a severe ulcer on my duodnem(sp?). are there any new findings, any new research? treatment makes day to day life hard because i am a hairstyling instructor, and with dilated eyes, it makes detail work hard. i've had a few steroid shots in the eyes, and lots of medrol packs...on top of pred forte and dilating drops..
