Dr Phil Turnbull

B Optom (Hons), PhD


I am a lecturer in the School of Optometry and Vision Science. I graduated from the University of Auckland with a Bachelor of Optometry (Hons), leaving to work in private practice in Christchurch for two years, before returning to undertake a PhD with Dr John Phillips investigating emmetropisation in squid. Following completion of my PhD, I worked as a contact lens specialist in the University Eye Clinic, and co-founded the Myopia Control Clinic, a translational research clinic promoting the latest myopia control research to the public. Following this, I undertook a joint postdoctoral fellowship under Professor Steven Dakin and Dr Phillips, combining myopia research with objective measures of vision.

As a lecturer, I teach and examine both undergraduate and postgraduate optometry students. My current research investigates utilising technology to assess visual function, including virtual reality, infrared eyetracking, arterial spin labelling magnetic resonance imaging (ASL-MRI), and multifocal electroretinograms (mf-ERG). The aim is to create objective measures of visual function for conditions such as myopia, binocular vision disorders, glaucoma, diabetic retinopathy, and age-related macular degeneration.
