Common Patient Question: “How likely am I to get AMD if a family member has it?”
• The Answer: That depends on several variables, but we do have an online calculator that can offer some guidance. Authors of a study comprised of over 2,800 patients used statistical analysis to develop the calculator, which provides an estimated risk of developing advanced AMD for up to 10 years out.
• Background Information: The Advanced AMD Risk Calculator can be accessed at http://caseyamdcalc.ohsu.edu . It asks for three main descriptors:
- Risk factors. The patient’s age, smoking status and family history of AMD in first degree relatives (i.e. parents or siblings).
- Retinal exam information. Are there large drusen? Macular pigmentary changes? Age-related changes in the macula are graded on a scale of 0 to 4, and the reference for the grading can be found at http://caseyamdcalc.ohsu.edu/instructions.aspx .
- Genotype information. This is optional, but if genotyping results are available for gene variants CFH (rs1061170) and ARMS2 (rs10490924), you can input these.
Given that smoking and diet are modifiable risk factors for AMD, this calculator may be a useful patient education tool to encourage your patients to pursue healthy lifestyles. OM

CORRECTION: In April’s “What’s New” section (p.50), the incorrect URL was published for RevCycle Partners in the item “Credentialing Service.” The correct URL is revcycle-partners.com . OM apologizes for the error.
CORRECTION: Several readers have brought to our attention a misleading statement that appears in April’s “Leading Off” story, “O.D.s Discuss Using a Compounding Pharmacy“ (p.14): “Because compounded drugs are not FDA evaluated, those who prescribe them must evaluate compounding pharmacies to ensure patient and practice safety.” To clarify, while compounded drugs aren’t FDA approved, each ingredient in the formulation of a compounded drug is FDA-approved. In addition, compounders that are designated as 503 B (that is, outsourcing facilities) are, in fact, inspected by the FDA. They also must meet certain conditions, such as reporting adverse events to the FDA. (For additional information, see https://bit.ly/2K7gxmd ). OM apologizes for any confusion the original statement may have caused.
