Multiple Cause Diagram (MCD) to explore treatment options of chronic blepharitis
Multiple Cause Diagrams (MCDs) can
be used to find solutions to systemic problems. This diagram tries to explore
treatment options that could theoretically be available to a person who has been
diagnosed with a particular type of blepharitis (inflammation of eye lids). This
type of blepharitis often leads to 'pink eye' and 'dry eye syndrome'. It is caused by rosacea of the eye lids, a
systemic disease which can only be controlled but not cured. The MCD also assumes that the patient's tear
glands do not produce enough tears, which further complicates his eye condition. The broken green lines indicate treatment options.Their aim is to weaken or disrupt links that keep the malignant process going.
Hypothetically a person afflicted by this condition
could construct a MCD similar to the one shown, based on authoritative
information from his ophthalmologist and bonafide medical websites. It could
serve to improve his /her understand of their condition and the treatment
available. As such, I believe this diagram
demonstrates the usefulness of MCDs.
