Well, I know there is an episode of House (season 1) that deals with something like this.
I've heard that high cholesterol can be a contributing factor to a ring, but it is usually found in people over 40. However, it can still occur in younger people. An ophthalmologist would know better than me, of course. :)
Another factor I've heard of that could cause a ring has something to do with liver damage. Not to be the cause of alarm, but it is something worth considering if the yellow band is concentrated or if it expands.
Good luck!

Wilsons disease is the condition scripted into house, it is caused by the bodys inabilty to bind copper. The copper builds up in the liver and kidneys and damages them. copper rings are seen around the iris, not the pupil, due to their deposition. And there is no mistaking copper for yellow in these cases so dont worry :)
