Johanna M. Seddon, MD, ScM


Dr. Seddon is widely recognized for her groundbreaking research on nutritional factors and the association with AMD, as well as her novel discoveries regarding genetic, biologic, and environmental factors associated with macular degeneration.

Research Interests

Dr. Seddon’s special research expertise is in evaluating and discovering the causes of macular degeneration, and the implications for prevention and cures. She has had continuous funding from the NIH and several retina foundations for her work in both the genetic components of this disease, as well as the environmental causes.

Current Research

Recent breakthroughs in the Seddon Laboratory include the discovery of new genes related to macular degeneration, including the discovery of new of rare genetic variants that strongly increase familial risk of AMD. These genes are now targets for new therapies. She has also shown that eating a healthy diet can partly overcome genetic susceptibility for the disease.

Dr. Seddon and her team initiated the development of many prediction models that combine genes and lifestyle factors related to macular degeneration, and validated the model. Dr. Seddon recently implemented her most recent prediction model for progression to advanced stage macular degeneration in the form of an online risk calculator. This calculator could be used in the future to examine personal risk factors as well as gain an estimate of individual risk for this disease.

Risk Calculator

Genetic variants related to AMD point to the underlying biology of the disease and can become therapeutic targets. A set of these markers known to be associated with AMD, along with knowledge of other non-genetic predictors (including age, sex, education, BMI, and smoking history) can be used to calculate a score associated with an individual probability of progressing to advanced disease. These probabilities can range from very low to very high, depending on the combination of individual risk factors. This knowledge can be useful for identifying high-risk individuals for lifestyle changes related to modifiable risk factors, selecting high-risk subjects for participation in clinical trials, and prescribing appropriate therapies.

Risk score models may also enhance patient management by clinicians, including advising on preventative measures, frequency of monitoring, assisting with the differential diagnosis of AMD and its subtypes, and possible diagnosis of treatable neovascular disease at an earlier stage. The risk calculator could also assist in the development of personalized medicine approaches for AMD.
