Hello Susan
I hope you don’t mind me replying to your post. This is a topic that comes up from time to time on the Myeloma Infoline.
Eye problems can occur in myeloma patients for a variety of reasons both as a result of the myeloma itself and as a result of the side–effects of certain treatments.
Eye problems associated with myeloma are more often a problem in the early stages before the myeloma has been brought under control by treatment.
There are several potential causes but the most common is a condition called hyperviscosity of the blood. This happens when there are large amounts of paraprotein/free light chains causing the blood to thicken. This can damage the blood vessels in the eye resulting in blurred and double vision.
Dexamethasone (steroid) treatment can cause eye problems following prolonged use because it can increase pressure within the eye and also cause cataracts.
Velcade can also cause problems with the eyes such as blurred vision, infections such as conjunctivitis and eye pain, so please do let your doctor or nurse specialist know that you have these symptoms.
With best wishes
Ellen
