Eye movement abnormalities in movement disorders.

Clin Park Relat Disord 2019 30;1:54-63. Epub 2019 Aug 30.

The Truong Neuroscience Institute, Orange Coast Memorial Medical Center, Fountain Valley, CA 92708, USA.

The visual system represents the most well-developed sensory system in humans, who are highly dependent on vision for organized response to their environment. The region of eye that is responsible for sharp central vision is the fovea. Thus, to see the world, images of objects of interest should fall on fovea. Read More

The Relationship Between Visual Sensitivity and Eccentricity, Cone Density and Outer Segment Length in the Human Foveola.

Invest Ophthalmol Vis Sci 2021 Jul;62(9):31

Department of Ophthalmology, Rheinische Friedrich-Wilhelms-Universität Bonn, Bonn, Germany.

Purpose: The cellular topography of the human foveola, the central 1° diameter of the fovea, is strikingly non-uniform, with a steep increase of cone photoreceptor density and outer segment (OS) length toward its center. Here, we assessed to what extent the specific cellular organization of the foveola of an individual is reflected in visual sensitivity and if sensitivity peaks at the preferred retinal locus of fixation (PRL).

Methods: Increment sensitivity to small-spot, cone-targeted visual stimuli (1 × 1 arcmin, 543-nm light) was recorded psychophysically in four human participants at 17 locations concentric within a 0. Read More

Short term morphological rescue of the fovea after gene therapy with voretigene neparvovec.

Acta Ophthalmol 2021 Jul 21. Epub 2021 Jul 21.

Center for Ophthalmology, University Eye Hospital, University of Tübingen, Tübingen, Germany.

Purpose: Leber congenital amaurosis type 2 (LCA2) and early-onset severe retinal dystrophy (EOSRD) are linked to visual impairment with nyctalopia and visual acuity reduction in early childhood. In 2017, the first gene therapy voretigene neparvovec (Luxturna™) for patients with LCA and EOSRD cause by bi-allelic mutations in the RPE65 gene has been approved. Here we report on an example of short-term change in the foveal morphology after functionally successful gene therapy with voretigene neparvovec in a 15-year old patient. Read More

Behavioural Adaptation to Hereditary Macular Dystrophy: A Systematic Review on the Effect of Early Onset Central Field Loss on Peripheral Visual Abilities.

Br Ir Orthopt J 2021 16;17(1):104-118. Epub 2021 Jun 16.

University of Sheffield, GB.

Purpose: Hereditary macular dystrophies (HMD) result in early onset central field loss. Evidence for cortical plasticity has been found in HMD, which may enhance peripheral visual abilities to meet the increased demands and reliance on the peripheral field, as has been found in congenitally deaf adults and habitual action video-game players. This is a qualitative synthesis of the literature on the effect of early onset central field loss on peripheral visual abilities. Read More

Three-dimensional segmentation and depth-encoded visualization of choroidal vasculature using swept-source optical coherence tomography.

Exp Biol Med (Maywood) 2021 Jul 14:15353702211028540. Epub 2021 Jul 14.

Department of Bioengineering, University of Washington, Seattle, WA 98105, USA.

The choroid provides nutritional support for the retinal pigment epithelium and photoreceptors. Choroidal dysfunction plays a major role in several of the most important causes of vision loss including age-related macular degeneration, myopic degeneration, and pachychoroid diseases such as central serous chorioretinopathy and polypoidal choroidal vasculopathy. We describe an imaging technique using depth-resolved swept-source optical coherence tomography (SS-OCT) that provides full-thickness three-dimensional (3D) visualization of choroidal anatomy including topographical features of individual vessels.

Fixation stability after surgical treatment of strabismus and biofeedback fixation training in amblyopic eyes.

BMC Ophthalmol 2021 Jun 24;21(1):264. Epub 2021 Jun 24.

Department of Ophthalmology, Semmelweis University, Budapest, Hungary.

Background: Visual fixation may be affected in amblyopic patients and, moreover, its stability may be associated with the effects of amblyopic treatments on visual performance in patients with strabismus. Therefore, fixation stability is a relevant biomarker that might predict the recurrence of amblyopia after a therapeutic intervention. Microperimetric biofeedback fixation training (BFT) can stabilize visual fixation in adult patients with central vision loss. Read More

Müller cells and astrocytes in tractional macular disorders.

Prog Retin Eye Res 2021 Jun 5:100977. Epub 2021 Jun 5.

Department of Ophthalmology and Eye Hospital, University of Leipzig, 04103, Leipzig, Germany.

Tractional deformations of the fovea mainly arise from an anomalous posterior vitreous detachment and contraction of epiretinal membranes, and also occur in eyes with cystoid macular edema or high myopia. Traction to the fovea may cause partial- and full-thickness macular defects. Partial-thickness defects are foveal pseudocysts, macular pseudoholes, and tractional, degenerative, and outer lamellar holes. Read More

A bias in saccadic suppression of shape change.

Vision Res 2021 Sep 2;186:112-123. Epub 2021 Jun 2.

Allgemeine und Biologische Psychologie, Philipps-Universität Marburg, Marburg, Germany; Center for Mind, Brain and Behaviour, Philipps-Universität Marburg, Marburg, Germany.

Processing of visual information in the central (foveal) and peripheral visual field is vastly different. To achieve a homogeneous representation of the visual world across eye movements, the visual system needs to compensate for these differences. By introducing subtle changes between peripheral and foveal inputs across saccades, one can test this compensation. Read More

Baseline Optical Coherence Tomography Parameters That May Influence 6 Months Treatment Outcome of Polypoidal Choroidal Vasculopathy Eyes with Combination Therapy: A Short-Term Pilot Study.

Int J Environ Res Public Health 2021 05 18;18(10). Epub 2021 May 18.

Department of Ophthalmology, Hospital Shah Alam, Persiaran Kayangan, Seksyen 7, Shah Alam 40000, Malaysia.

Although optical coherence tomography (OCT) parameters have assisted in the diagnosis of polypoidal choroidal vasculopathy (PCV), its potential to evaluate treatment outcomes has not been established. The purpose of this pilot study was to evaluate baseline OCT parameters that may influence treatment outcome in PCV eyes with combination therapy. In this single-centered, prospective study, patients were recruited with at least one treatment-naïve PCV eye and treated with combination therapy of intravitreal anti-vascular endothelial growth factor and photodynamic therapy.

A window into the future? MRI for evaluation of neuromyelitis optica spectrum disorder throughout the disease course.

Ther Adv Neurol Disord 2021 9;14:17562864211014389. Epub 2021 May 9.

St. Michael's Hospital, 30 Bond Street, Shuter 3-018, Toronto, ON, M5B 1W8, Canada.

Neuromyelitis optica spectrum disorder (NMOSD) is a relapsing, inflammatory disease of the central nervous system marked by relapses often associated with poor recovery and long-term disability. Magnetic resonance imaging (MRI) is recognized as an important tool for timely diagnosis of NMOSD as, in combination with serologic testing, it aids in distinguishing NMOSD from possible mimics. Although the role of MRI for disease monitoring after diagnosis is not as well established, MRI may provide important prognostic information and help differentiate between relapses and pseudorelapses.
