Research Interests
Myopia (nearsightedness) is a potentially blinding eye condition, and is the most common human eye disorder. Genetic studies of high-grade myopia- primarily performed by members of this consortium- are promising but limited, and historically have been small sample-size reports. Molecular genetic analyses of myopia in general have not been fully explored, and findings to date suggest a difference in genetic influences in high-grade myopia versus that of moderate myopia. The goal of my research is to gain a greater understanding of the molecular genetic basis of high-grade myopia. My research program was initially based on large-pedigree, family-based Mendelian trait myopia genetics in the United States, but in recent years has expanded to include international collaborations in Europe with other family studies, and twin studies. More recently we now have collaborative projects studying refractive error genetics in large case-control and population studies in Singapore.
I hypothesize that the identification of myopia susceptibility genes will not only provide insight into the molecular basis of this significant eye disorder, but will also identify pathways that are involved in eye growth and development. This effort may lead to effective therapies to treat or potentially prevent this common eye condition
This faculty member has no reported relationships with industry.
