Robert MacLaren is Professor of Ophthalmology at the University of Oxford, Consultant Ophthalmologist at the Oxford Eye Hospital, Honorary Professor of Ophthalmology at the UCL Institute of Ophthalmology, Honorary Consultant Vitreoretinal Surgeon at Moorfields Eye Hospital, Faculty Member and Founding Theme Leader of the Moorfields-UCL Institute of Ophthalmology Biomedical Research Centre and an NIHR Senior Investigator. He is also a Fellow of the Royal College of Ophthalmologists, Fellow and former King James IV Professor of Surgery at the Royal College of Surgeons of Edinburgh, Fellow of the American College of Surgeons, Fellow of the Academy of Medical Sciences, Bodley Fellow of Merton College Oxford and Civilian Consultant Advisor to the Royal Navy. He has been a recipient of the ARVO Camras Award for Translational Research, the RP Fighting Blindness Scientist of the Year Award, the American Academy of Ophthalmology Achievement Award and a Euretina Innovation Award. Together with the University of Oxford in 2014 he co-founded Nightstar, a biotechnology company originally based at the Wellcome Trust in London and now listed on NASDAQ, in order to develop further gene therapy treatments for patients with retinal diseases.

Research Summary

Our clinical and laboratory research is dedicated to finding new treatments for blindness, particularly in patients with incurable retinal diseases, using stem cell-based approaches, gene therapy or electronic retinas. We are also developing new techniques for cataract and retinal surgery. Our recent research achievements include:

  • 2018: Successful completion of the world's first gene therapy trial for choroideremia, meeting the primary endpoint of showing beneficial effects on vision (Nature Medicine, 2018).
  • 2017: First in man gene therapy clinical trial for X-linked retinitis pigmentosa in collaboration with Nightstar (BBC World Service).
  • 2016: First in man use of a robot to operate inside the eye in collaboration with Preceyes BV (Nature Biomedical Engineering, 2018).
  • 2016: Long term efficacy of retinal gene therapy in choroideremia, leading to sustained improvement in visual acuity in patients over several years (New Eng J Med, 2016)
  • 2015: Demonstration of efficacy of a new molecular treatment to prevent vitamin A dimerization in a mouse model of Stargardt disease (Proc Natl Acad Sci USA, 2015)
  • 2014: Assessment of novel lentiviral vectors for gene therapy in the eye and on human retinal tissues (Hum Gene Ther, 2014)
  • 2013: Reconstruction of the outer retina using a cell therapy approach in mice that are completely blind from end-stage retinal degeneration (Proc Natl Acad Sci USA, 2013)
  • 2012: First electronic retinal implant surgery in the UK as part of a multicentre clinical trial with Retina Implant AG (Vision Res, 2015)
  • 2011: Initial first in man clinical trial of gene therapy to treat choroideremia showing safety and early signs of efficacy (Lancet, 2014)
  • 2010: Development of novel cataract surgery techniques for patients with complex retinal diseases (J Cataract Refract Surg, 2011, J Cataract Refract Surg, 2014)
