    In this edition of Advances in Eyecare, we hear from four experts about developments in treatments, assessments and our understanding of human vision. 

    Prof John Flanagan talks about a potential new treatment for glaucoma and explains the neuroprotective role of lipoxin around ganglion cells and how maintenance of this may offer new options in management of the disease.

    Dr Kathleen Vancleef discusses the ASTEROID project’s new technology, and how its new methodology promises to make the assessment of younger patients easier. 

    Dr Vivek Nityananda offers a unique insight into how we may better understand human stereo vision through his research into the stereo vision of praying mantises as part of the ‘Man, mantis and machine: the computation of 3D vision’ project.

    Prof Jenny Read, Principal Investigator on the ASTEROID project and ‘Man, mantis and machine: the computation of 3D vision’, talks virtual reality and 3D displays, and the potential impact of prolonged use of virtual reality displays upon the visual system.

      Learning objectives

      • 1.1.2 Understand the underlying lipoxin-mediated process in glaucoma and neurodegenerative disorders such as Alzheimer's disease and understand its likely influence upon future intervention in treatment.
      • 2.5.3 Understand the latest research about the pathophysiology of glaucoma and neurodegenerative disease so to be better able to inform patients and adapt practice as they impact in future.
      • 6.1.8 Understand the underlying physiological changes at neuronal level in glaucoma, which may progress independent of IOP changes, and so be better able to assess and explain both current disease progress and the implications for future treatments.
      • 8.1.1 Understand the limitations of current stereopsis tests and the benefits of newly developing digital display alternatives.

        Unit 1 - Lipoxins in the treatment of glaucoma (~11 mins)

        Professor John Flanagan interviewed by Geoff Watts

        Glaucoma, in its various forms, is a leading cause of blindness in the world according to the World Health Organisation. The disease has no current cure and medical intervention is still focused upon the management of intraocular pressure. However, many who receive treatment still experience loss of vision. Professor John Flanagan, Dean and Professor of Optometry at the University of California Berkeley, discusses a potential new treatment for glaucoma which is centred around a better understanding of the disease at a cellular level.

        Unit 2 - Accurate stereo test for mobile device (ASTEROID) (~10 mins)

        Dr Kathleen Vancleef interviewed by Vincente Puyat

        The first few years of life are critical for binocular development to avoid binocular vision disorders such as amblyopia or strabismus. However, children at this age are notoriously difficult to examine and assess, meaning that the results can often be unreliable. The ASTEROID project’s new technology and methodology promises to improve on this, making the assessment of younger patients easier.

        Unit 3 - Stereo vision in the praying mantis (~7 mins)

        Dr Vivek Nityananda interviewed by Vincente Puyat

        Praying mantises are the only invertebrates known to have stereo vision. Dr Vivek Nityananda, a behavioural ecologist, is currently investigating the mechanisms underlying stereo vision in the praying mantis as part of a project called ‘Man, mantis and machine: the computation of 3D vision’. Here, he discusses his research with us and its implications on our understanding of human stereo vision.

        Professor Jenny Read interviewed by Vincente Puyat

        Jenny Read is the Principal Investigator on the ASTEROID project and ‘Man, mantis and machine: the computation of 3D vision’. She talks to us here about virtual reality and 3D displays, and the potential impact of prolonged use of virtual reality displays upon the visual system.
