I'm not sure that a CT or MRI is indicated. It could be a side effect of medications, particularly steroids like prednisone and some blood pressure pills. I have also seen this sort of thing in smokers and overweight individuals with or without some allergies thrown in. Lid margin disease is also a common finding. The main thing for your opthalmologist is to rule out anything bad or harmful, then take some steps to at least offer some sort of help for this chronic problem.

Dr. Kutryb, Thanks so much for your response. I was taking prednisone for an ear
problem shortly before the swelling began. I also take atenolol, I'm not sure if that
would be classified as a blood pressure medicine, but I will discuss these things
with my doctor. Thanks again.
