Professor David Mackey is the chair of Ophthalmology at the University of Western Australia and Managing Director of the Lions Eye Institute in Perth. He is a former councillor of the Royal Australian and New Zealand College of Ophthalmologists and current RANZCO representative on the Council of the Asia Pacific Academy of Ophthalmology. He is past president of the International Society for Genetic Eye Disease and Retinoblastoma. Prof Mackey is a renowned international researcher in the genetics of eye disease having published over 340 peer-reviewed papers since 1989. He is the world’s most published author in glaucoma genetics and is a lead investigator in the International Glaucoma Genetics Consortium (IGGC) and the Consortium for Refractive Error and Myopia (CREAM). In 1993 Professor Mackey initiated the Glaucoma Inheritance Study in Tasmania (GIST) , thereby creating one of the largest glaucoma biobanks in the world, with over 5,000 DNA samples and clinical material from familial and sporadic cases of glaucoma. His research has extended beyond the laboratory to cascade genetic screening for at-risk individuals. His group has examined the impact of providing DNA testing and results to glaucoma families and is currently working on models of cascade family screening for glaucoma.
