This causes symptoms such as:
- visual disturbances
- spontaneous bleeding
The visual disturbance is described as 'looking through a watery car windscreen'
The optic disc may occur blurred.
Normal plasma viscosity is 1.4-1.8. Hyperviscosity syndrome develops above around 4.
Causes of hyperviscosity syndrome include:
- Waldenstroms macroglobulinaemia
Treatment depends on the cause; in myeloma/waldenstroms the patient needs plasmaphersis whereas in polycythaemia the treatment is venesection.
So now seems a good time to battle Waldenstrom's macroglobulinaemia...
