Multimodal imaging in a patient with Prader-Willi syndrome.

Int J Retina Vitreous 2018 30;4:45. Epub 2018 Nov 30.

Gavin Herbert Eye Institute, University of California Irvine, 850 Health Sciences Road, Irvine, CA 92697 USA.

Background: Prader-Willi syndrome (PWS) is a genetic disease caused by loss of expression of the paternally inherited copy of several genes on the long arm of chromosome 15. Ophthalmic manifestations of PWS include strabismus, amblyopia, nystagmus, hypopigmentation of the iris and choroid, diabetic retinopathy, cataract and congenital ectropion uvea. An overlap between PWS and oculocutaneous albinism (OCA) has long been recognized and attributed to deletion of OCA2 gene located in PWS critical region (PWCR). Read More

Authors:
Minako Kaido

Invest Ophthalmol Vis Sci 2018 Nov;59(14):DES29-DES35

Department of Ophthalmology, Keio University School of Medicine, Tokyo, Japan.

Dry eye (DE) causes irregularity of the ocular surface and reduces the quality of vision. An intact, regular tear film is essential for high-quality retinal images; however, visual tasks requiring sustained gazing can disrupt the tear film, eventually degrading visual function. A functional visual acuity (FVA) measurement system has been uniquely developed in Japan to evaluate visual function related to tear stability in patients with DE. Read More

Self-perception of School-Aged Children With Amblyopia and Its Association With Reading Speed and Motor Skills.

JAMA Ophthalmol 2018 Nov 15. Epub 2018 Nov 15.

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

Importance: Reading and eye-hand coordination deficits in children with amblyopia may impede their ability to demonstrate their knowledge and skills, compete in sports and physical activities, and interact with peers. Because perceived scholastic, social, and athletic competence are key determinants of self-esteem in school-aged children, these deficits may influence a child's self-perception.

Objective: To determine whether amblyopia is associated with lowered self-perception of competence, appearance, conduct, and global self-worth and whether the self-perception of children with amblyopia is associated with their performance of reading and eye-hand tasks. Read More

Atropine Penalization Versus Occlusion Therapies for Unilateral Amblyopia after the Critical Period of Visual Development: A Systematic Review.

Ophthalmol Ther 2018 Dec 16;7(2):323-332. Epub 2018 Oct 16.

Clinical and Experimental Sciences, Faculty of Medicine, University of Southampton, Southampton, UK.

Introduction: Amblyopia therapy appears to be most effective in children under the age of 7 years, but results from randomized control trials (RCTs) have shown that occlusion therapy and/or atropine penalization therapy may improve visual acuity in an older age group. Which of these two therapies is the most effective with fewer adverse effects in an older age group has not yet been agreed upon.

Methods: We systematically searched the literature for RCTs that compared atropine penalization therapy and occlusion therapy in terms of their visual acuity outcomes and adverse events and performed a meta-analysis on the visual acuity data obtained. Read More

A Novel Dichoptic Optokinetic Nystagmus Paradigm to Quantify Interocular Suppression in Monocular Amblyopia.

Invest Ophthalmol Vis Sci 2018 Oct;59(12):4775-4782

Department of Ophthalmology & Visual Science, Eye & ENT Hospital, Shanghai Medical College, Fudan University, Shanghai, China.

Purpose: To develop a novel dichoptic optokinetic nystagmus (OKN) paradigm and investigate its effectiveness in objectively quantifying the interocular suppression in subjects with monocular amblyopia.

Methods: Centripetal moving gratings with different contrast ratios and constant velocity were dichoptically presented to eight monocular anisometropic amblyopes and eight normal subjects. We analyzed the OKN records with an eye tracker (EyeLink; SR-Research, Ontario, Canada) to obtain the relationship between ocular-dominance of OKN and the interocular contrast ratio by fitting power curves, and examined the correlation between the effective contrast ratio for a balanced OKN and the visual acuity of the amblyopic eye in amblyopes.

A comparison of tests for quantifying sensory eye dominance.

Vision Res 2018 12 22;153:60-69. Epub 2018 Oct 22.

UCL Institute of Ophthalmology, University College London, Bath St, London EC1V 9EL, UK; School of Optometry and Vision Science, University of Auckland, Auckland 1142, New Zealand; New Zealand National Eye Centre, University of Auckland, Auckland 1142, New Zealand. Electronic address:

Clinicians rely heavily on stereoacuity to measure binocular visual function, but stereo-vision represents only one aspect of binocularity. Lab-based tests of sensory eye dominance (SED) are commonplace, but have not been translated to wider clinical practice. Here we compare several methods of quantifying SED in a format suitable for clinical use. Read More

Transcranial direct-current stimulation (tDCS) improves detection of simple bright stimuli by amblyopic Long Evans rats in the SLAG task and produces an increase of parvoalbumin labelled cells in visual cortices.

Brain Res 2018 Oct 1. Epub 2018 Oct 1.

Universidad de Almería, Departamento de Psicología. Ctra. Sacramento S/N, 04120, La Cañada de San Urbano, Almería, Spain; Centro de Evaluación y Rehabilitación Neuropsicológica (CERNEP), Ctra. Sacramento S/N, 04120, La Cañada de San Urbano, Almería, Spain.

In this work visual functional improvement of amblyopic Long Evans rats treated with tDCS has been assessed using the "slow angled-descent forepaw grasping" (SLAG) test. This test is based on an innate response that does not requires any memory-learning component and has been used before for measuring visual function in rodents. The results obtained show that this procedure is useful to assess monocular but not binocular deficits, as controls and amblyopic animals showed significant differences during monocular but not during binocular assessment.
