Ocular Genetics

Research Overview

Research in the Ocular Genetics lab focuses on using a range of cutting edge genetic techniques combined with informatics to identify gene and environmental determinants of common complex eye diseases. A particular focus is made on age related macular degeneration (AMD), myopia and keratoconus. Current projects involve the use of genome wide association, whole exome sequencing, methylation, copy number studies and gene-gene interaction studies with the aim of personalising patient care. Prof Baird is a member of the Consortium for Refractive Error and Myopia (CREAM) and the International AMD Genomics Consortium (IAMDGC) and is currently collaborating with a number of national and international groups using large population and data resources to unlock the causes of these eye diseases.

Current projects in AMD  include investigating the role of gene-gene interactions using high throughput computational analysis across the genome; pharmacogenetic studies of anti-vascular endothelial growth factors; risk prediction models identifying individuals at early disease stage and the role of the immune system in disease pathogenesis.

In the case of keratoconus, the Australian Study of Keratoconus has been established to better understand the role of genetic and environmental risk factors through the recruitment of 375 keratoconus patients. Studies include establishing a number of genetic associations with keratoconus, the role of asthma in increasing severity of this disease; the use of imaging and risk factor profile in identifying progression of disease as well as  an analysis of its economic burden.

In myopia, genetic association studies of refractive error as well as endophenotypes are being undertaken with national and international partners as well as the role that copy number plays. Additionally, gene-environmental interactions are being assessed in both adults and children to better understand the role of different risk factors in this rapidly increasing problem around the world.
