    Does air gas aesthesiometry generate a true mechanical stimulus for corneal sensitivity measurement?
    Clin Exp Optom 2017 Sep 18. Epub 2017 Sep 18.
    School of Optometry and Vision Science, University of Waterloo, Waterloo, Ontario, Canada.
    Background: Belmonte Ocular Pain Meter (OPM) air jet aesthesiometry overcomes some of the limitations of the Cochet-Bonnet aesthesiometer. However, for true mechanical corneal sensitivity measurement, the airflow stimulus temperature of the aesthesiometer must equal ocular surface temperature (OST), to avoid additional response from temperature-sensitive nerves. The aim of this study was to determine: (A) the stimulus temperature inducing no or least change in OST; and (B) to evaluate if OST remains unchanged with different stimulus durations and airflow rates.

    Rethinking contact lens aftercare.
    Clin Exp Optom 2017 Sep 4. Epub 2017 Sep 4.
    Eurolens Research, The University of Manchester, Manchester, UK.
    The evolution of contact lens technology and clinical practice over the past three decades has been remarkable, with dramatic improvements in material biocompatibility, better lens designs and care systems, and more flexible and convenient modalities of wear. However, our approach to the aftercare examination has remained conservative, with the general modus operandi having not fully evolved from the difficult, early years of fitting non-regular replacement rigid and low water content hydrogel lenses. In this paper, we review current aftercare practice and in particular, the preferred frequency that lens wearers should return for routine visits and the appropriateness of regulations governing contact lens prescription expiry.

    The effects of preterm birth on visual development.
    Clin Exp Optom 2017 Sep 3. Epub 2017 Sep 3.
    Department of Paediatrics, The University of Auckland, Auckland, New Zealand.
    Children born very preterm are at a greater risk of abnormal visual and neurological development when compared to children born at full term. Preterm birth is associated with retinopathy of prematurity (a proliferative retinal vascular disease) and can also affect the development of brain structures associated with post-retinal processing of visual information. Visual deficits common in children born preterm, such as reduced visual acuity, strabismus, abnormal stereopsis and refractive error, are likely to be detected through childhood vision screening programs, ophthalmological follow-up or optometric care.

    Contact lens technology to 2020 and beyond: a review of recent patent literature.
    Clin Exp Optom 2017 Sep 3. Epub 2017 Sep 3.
    School of Optometry and Vision Science, The University of New South Wales, Kensington, New South Wales, Australia.
    Contact lenses have been a common means of vision correction for more than half a century. Recent developments raise the possibility that the next several years will see the range of applications in which they are used broaden considerably, with an associated expansion in both the number and type of individuals who consider them to be a valuable option. To describe this new landscape, a review of recent patent submissions covering the period 1 January 2014 to 1 February 2017 was undertaken. Read More

    The diagnosis and management of contact lens-related microbial keratitis.
    Clin Exp Optom 2017 Aug 16. Epub 2017 Aug 16.
    School of Optometry and Vision Science, The University of New South Wales, Sydney, New South Wales, Australia.
    Contact lens-associated microbial keratitis poses a diagnostic dilemma for optometrists on two fronts. The distinction between sterile inflammation and microbial infection is often blurred. In addition, there is a requirement with nearly 50 per cent of the Australian and New Zealand optometric profession being therapeutically endorsed, to distinguish between cases of infection that can be managed in the community verses those that require escalation to public hospitals that have access to laboratory diagnostic tools and advanced imaging techniques, such as in vivo confocal microscopy.

    Disturbing the balance: effect of contact lens use on the ocular proteome and microbiome.
    Clin Exp Optom 2017 Aug 3. Epub 2017 Aug 3.
    School of Optometry, The Hong Kong Polytechnic University, Hong Kong.
    Contact lens wear is a popular, convenient and effective method for vision correction. In recent years, contact lens practice has expanded to include new paradigms, including orthokeratology; however, their use is not entirely without risk, as the incidence of infection has consistently been reported to be higher in contact lens wearers. The explanations for this increased susceptibility have largely focused on physical damage, especially to the cornea, due to a combination of hypoxia, mechanical trauma, deposits and solution cytotoxicity, as well as poor compliance with care routines leading to introduction of pathogens into the ocular environment.

    Contact lenses to slow progression of myopia.
    Clin Exp Optom 2017 Jul 28. Epub 2017 Jul 28.
    Brien Holden Vision Institute, Sydney, New South Wales, Australia.
    The prevalence of myopia has been steadily rising, with 28 per cent of the global population said to be affected in 2010 and to rise to affect nearly 50 per cent by 2050. Increasing levels of myopia increase the risk of vision impairment and in particular, high myopia is associated with the risk of serious and permanent visual disability due to associated sight-threatening complications. To stem the burden associated with higher levels of myopia, there are efforts to slow the progression of myopia, and several optical and pharmaceutical strategies have been found useful in slowing myopia to varying degrees.

    The use of contact lenses in low vision rehabilitation: optical and therapeutic applications.
    Clin Exp Optom 2017 Jun 29. Epub 2017 Jun 29.
    Contact Lens and Visual Optics Laboratory, School of Optometry and Vision Science, Queensland University of Technology, Kelvin Grove, Queensland, Australia.
    Ocular pathology that manifests at an early age has the potential to alter the vision-dependent emmetropisation mechanism, which co-ordinates ocular growth throughout childhood. The disruption of this feedback mechanism in children with congenital or early-onset visual impairment often results in the development of significant ametropia, including high levels of spherical refractive error, astigmatism and anisometropia. This review examines the use of contact lenses as a refractive correction, low vision aid and therapeutic intervention in the rehabilitation of patients with bilateral, irreversible visual loss due to congenital ocular disease.

    Binocular facilitation of cone-specific visual evoked potentials in colour deficiency.
    Clin Exp Optom 2017 Jun 21. Epub 2017 Jun 21.
    The Rosenberg School of Optometry, University of the Incarnate Word, San Antonio, Texas, USA.
    Background: Neural compensatory mechanisms have been proposed, which preserve the binocular visual field in glaucoma, as well as cognition in Alzheimer's disease and motor function in Parkinson's disease. It is conceivable that comparable mechanisms operate to preserve function in congenital and/or dystrophic disease. In hereditary colour vision deficiency (CVD), we observed significant facilitation in the amplitude of the binocular cone-specific visual evoked potential (VEP) compared to the monocular amplitude for the cone type corresponding to the CVD.
