Alpha -adrenoceptor agonists inhibit form-deprivation myopia in the chick.

Clin Exp Optom 2019 Jan 30. Epub 2019 Jan 30.

Department of Cell Biology and Anatomy, Cumming School of Medicine, University of Calgary, Calgary, Alberta, Canada.

Background: The putative myopia-controlling receptor is thought to be muscarinic acetylcholine receptor subtype M , because mamba toxin-3 can inhibit form-deprivation myopia in chicks at a far lower concentration than atropine. However, mamba toxin-3 is equally potent at the human α -, α -, and α -adrenoceptors. To test the hypothesis that α-adrenoceptors might be involved in regulation of eye growth, the treatment effects of α -adrenoceptor agonists brimonidine, clonidine, and guanfacine, and antagonist yohimbine, on form-deprivation myopia in the chick were measured.

Anterior segment optical coherence tomography and its clinical applications: a review.

Clin Exp Optom 2019 Jan 12. Epub 2019 Jan 12.

Faculty of Medicine and Health, Save Sight Institute, The University of Sydney, Sydney Eye Hospital, Sydney, New South Wales, Australia.

Anterior segment optical coherence tomography (AS-OCT) has become one of the cornerstones of non-contact imaging modalities for assessing such structures as the cornea, anterior chamber angle, aqueous outflow pathway, sclera, and ocular surface structures. As such, it has a broad range of clinical applications, which have been independently reported in the literature. This paper aims to present a review of extant literature on the utility of AS-OCT and its efficacy in clinical applications, and to evaluate the quality of available evidence. Read More

Molecular evidence for the role of inflammation in dry eye disease.

Clin Exp Optom 2019 Jan 10. Epub 2019 Jan 10.

Department of Ophthalmology, New Zealand National Eye Centre, The University of Auckland, Auckland, New Zealand.

Ocular surface inflammation is propagated by a complex series of molecular processes and has been implicated in the pathogenesis of dry eye disease (DED), either as a causal or a downstream effect of ocular surface disease. A state of hyperosmolarity elicits an acute immune response in DED, leading to subsequent activation of the adaptive immune response. This cascade incites dysregulation of the immune system, triggering a vicious cycle of events that causes damage to the ocular surface. Read More

Choroidal changes in human myopia: insights from optical coherence tomography imaging.

Clin Exp Optom 2018 Dec 19. Epub 2018 Dec 19.

School of Optometry and Vision Science, Queensland University of Technology, Brisbane, Queensland, Australia.

The choroid is a vascular tissue which plays a range of critical roles in the normal physiology of the eye, such as supplying the outer retina with oxygen and nutrients and the regulation of intraocular pressure. There is also substantial evidence, particularly from animal studies, that the choroid plays an important role in the regulation of eye growth and the development of common refractive errors like myopia. In recent years, advances in optical coherence tomography technology have improved our ability to image and measure the choroid in the human eye. Read More

Optical coherence tomography in the investigation of systemic neurologic disease.

Clin Exp Optom 2018 Dec 11. Epub 2018 Dec 11.

Institute of Health and Biomedical Innovation, Queensland University of Technology, Brisbane, Queensland, Australia.

Optical coherence tomography (OCT) is a well-established technique for the clinical examination, diagnosis, severity staging and monitoring of ophthalmic disorders. The application of this technology has more recently been extended beyond ophthalmic disease, whereby it has been demonstrated that OCT can serve as an ophthalmic marker for a range of systemic neurodegenerative disorders, such as Parkinson's disease, multiple sclerosis, Alzheimer's disease and diabetic peripheral neuropathy. This review will focus on the clinical utility of OCT-derived retinal measures for the investigation of these conditions. Read More

Clin Exp Optom 2018 Dec 5. Epub 2018 Dec 5.

Contact Lens and Visual Optics Laboratory, School of Optometry and Vision Science, Queensland University of Technology, Brisbane, Queensland, Australia.

Background: The aim of this study was to examine the influence of B-scan averaging on choroidal thickness using wide-field enhanced-depth imaging optical coherence tomography.

Methods: Six high-resolution trans-foveal horizontal enhanced-depth imaging line scans (spanning a 60° field) were acquired consecutively from the right eye of 10 healthy adults (mean age 30 ± 5 years), with each line scan an average of 10, 20, 30, 40, 50 or 100 B-scans, using the automated real-time image averaging and follow-up features of a Spectralis device. The impact of B-scan averaging on regional measures of wide-field choroidal thickness (across macular and peripheral regions) and their accuracy was investigated, assuming that averaging 100 B-scans would provide the most accurate estimate of choroidal thickness.

Reticular pseudodrusen: current understanding.

Clin Exp Optom 2018 Oct 8. Epub 2018 Oct 8.

Centre for Eye Research Australia, Melbourne, Victoria, Australia.

Reticular pseudodrusen (RPD), also known as subretinal drusenoid deposits, represent a morphological change to the retina distinct from other subtypes of drusen by being located above the level of the retinal pigment epithelium. Although they can infrequently appear in individuals with no other apparent pathology, their highest rates of occurrence are in association with age-related macular degeneration (AMD), for which they hold clinical significance by being highly correlated with end-stage disease sub-types, choroidal neovascularisation and geographic atrophy. Reticular pseudodrusen are also found in other diseases, most notably Sorsby's fundus dystrophy, pseudoxanthoma elasticum and acquired vitelliform lesions. Read More

Although mobile applications are gaining acceptance among ophthalmologists and optometrists, little is known about their adoption among patients. Therefore, this study was designed to analyse the market for patient-oriented mobile applications in ophthalmology. Read More

Clin Exp Optom 2018 Aug 22. Epub 2018 Aug 22.

Optometry Section, Louis Stokes Cleveland Veterans Affairs Medical Centre, Cleveland, Ohio, USA.

Schizophrenia, a neurodevelopmental mental disorder with heterogeneous features, poses major social and health-care challenges in Australia and worldwide. Ophthalmic findings in patients with schizophrenia are varied and include conditions that result from psychotropic complications such as sun gazing, heritable genetic endophenotypes such as oculomotor abnormalities and strabismus, treatment-related complications such as chlorpromazine lenticular and corneal deposits, and co-morbid health problems such as poor compliance. This report reviews special considerations for eye care in schizophrenia and provides case examples to illustrate the complexity of problems that optometrists may encounter with this population.

Conjunctival ultraviolet autofluorescence area, but not intensity, is associated with myopia.

Clin Exp Optom 2019 Jan 16;102(1):43-50. Epub 2018 Aug 16.

Department of Optometry and Vision Science, Optometry and Vision Science Research Group, University of Ulster, Coleraine, UK.

Background: Conjunctival ultraviolet autofluorescence (CUVAF) has been used as a biomarker of time spent outdoors. Smaller CUVAF area is associated with myopia in southern hemisphere cohorts. Further research is required to determine if this association is replicated in northern latitudes and whether average CUVAF intensity is a valuable metric. Read More

The effect of corneal infiltrates on densitometry and higher-order aberrations.

Clin Exp Optom 2018 Aug 14. Epub 2018 Aug 14.

Ophthalmology Department, Ulucanlar Eye Training and Research Hospital, Ankara, Turkey.

Background: This study aimed to measure the effects of persistent corneal subepithelial infiltrates associated with epidemic keratoconjunctivitis on corneal densitometry and total corneal higher order aberrations (HOAs), and to compare these measurements with the data obtained from their fellow unaffected healthy eyes.

Methods: This prospective cross-sectional study included those who had persistent subepithelial infiltrates in only the affected eyes for at least three months and clinically normal fellow unaffected eyes. Corneal densitometry was measured with the densitometry software of the Pentacam HR-Scheimpflug corneal topographer over a 12 mm diameter of cornea. Read More

Tessellated fundus appearance and its association with myopic refractive error.

Clin Exp Optom 2018 Aug 9. Epub 2018 Aug 9.

Brien Holden Vision Institute, Sydney, New South Wales, Australia.

The appearance of tessellated fundus in an eye may act as a marker in identifying visual performance, degree of myopia or risk of progression of myopia in a given eye. A systematic literature search using key words was performed using PubMed, Web of Science and Google Scholar and of the 832 studies identified, 10 full-length articles, which met the inclusion criteria, were considered for review. The primary outcome measures were association of tessellated fundus with: (i) visual acuity, (ii) refractive error, (iii) axial length, (iv) choroidal thickness and (v) future progression of myopia when compared to either no myopic maculopathy, or more severe myopic maculopathy.

Ocular and systemic melatonin and the influence of light exposure.

Authors:
Lisa A Ostrin

Clin Exp Optom 2018 Aug 3. Epub 2018 Aug 3.

University of Houston College of Optometry, Houston, Texas, USA.

Melatonin is a neurohormone known to modulate a wide range of circadian functions, including sleep. The synthesis and release of melatonin from the pineal gland is heavily influenced by light stimulation of the retina, particularly through the intrinsically photosensitive retinal ganglion cells. Melatonin is also synthesised within the eye, although to a much lesser extent than in the pineal gland. Read More

Scene through the eyes of an apex predator: a comparative analysis of the shark visual system.

Authors:
Shaun P Collin

Clin Exp Optom 2018 Sep 1;101(5):624-640. Epub 2018 Aug 1.

The Oceans Institute and the Oceans Graduate School, The University of Western Australia, Perth, Western Australia, Australia.

The eyes of apex predators, such as the shark, have fascinated comparative visual neuroscientists for hundreds of years with respect to how they perceive the dark depths of their ocean realm or the visual scene in search of prey. As the earliest representatives of the first stage in the evolution of jawed vertebrates, sharks have an important role to play in our understanding of the evolution of the vertebrate eye, including that of humans. This comprehensive review covers the structure and function of all the major ocular components in sharks and how they are adapted to a range of underwater light environments. Read More
