Macula Risk

AMD is a genetic disease, meaning that it runs in families.   Having a first-degree relative (mother, father, brother, sister) with AMD suggests that you have a significantly increased risk of developing the disease.  However, some individuals are ‘carriers’ of a gene, without actually expressing its trait. Consider a child born with blue eyes when both parents have brown eyes.  Both parents are carriers of a gene for blue eyes, yet neither expresses it.  Similarly, it is still possible to inherit and develop AMD even if neither parent has the disease.

What is Macula Risk?

As seen in the table below, catagories MR1 and MR2 have a 2.5% and 9.5% respectively of developing advanced AMD. Patients in catagories MR3-MR5 have a mcuh greater chance of developing severe disease. Your eye doctor in Mesa or Glendale, AZ will use this information to help determine which preventative measures and therapeutic interventions best suit your individual needs.  Consider Macula Risk® as a crystal ball; it allows a peak into one's future affording doctors the opportunity to provide the best possible care for those at highest risk of developing advanced AMD.
