DO ORTHOPTIC EXERCISES HAVE ANY INFLUENCE ON CHILDREN AND ADOLESCENTS DIAGNOSED WITH CONVERGENCE INSUFFICIENCY AND ATTENTION DEFICIT/HYPERACTIVITY DISORDER?

Acta Clin Croat 2019 Dec;58(4):662-671

1Zagreb Children's Hospital, Zagreb, Croatia; 2Zagreb University Hospital Centre, Zagreb, Croatia.

The aim was to determine whether improvement of near point of convergence (NPC) and binocular vision after orthoptic exercises had any impact on children and adolescents diagnosed with attention deficit/hyperactivity disorder (ADHD) and convergence insufficiency (CI). In this clinical trial, 50 children and adolescents aged 6 to 18 years diagnosed with ADHD and CI received orthoptic therapy that included home-based exercises (pencil push-ups and stereograms) and office-based therapy on synoptophore. Binocular vision and NPC were measured before, during and after therapy. Read More

Layer 4 Gates Plasticity in Visual Cortex Independent of a Canonical Microcircuit.

Curr Biol 2020 Jun 18. Epub 2020 Jun 18.

Department of Anatomical Sciences and Neurobiology, School of Medicine, University of Louisville, Louisville, KY 40202, USA; Developmental Neuroscience Program, Saban Research Institute, Children's Hospital Los Angeles, Department of Pediatrics, Keck School of Medicine, University of Southern California, Los Angeles, CA 90027, USA. Electronic address:

Disrupting binocular vision during a developmental critical period can yield enduring changes to ocular dominance (OD) in primary visual cortex (V1). Here we investigated how this experience-dependent plasticity is coordinated within the laminar circuitry of V1 by deleting separately in each cortical layer (L) a gene required to close the critical period, nogo-66 receptor (ngr1). Deleting ngr1 in excitatory neurons in L4, but not in L2/3, L5, or L6, prevented closure of the critical period, and adult mice remained sensitive to brief monocular deprivation. Read More

Embracing Their Prey at That Dark Hour: Common Cuttlefish () Can Hunt in Nighttime Light Conditions.

Front Physiol 2020 10;11:525. Epub 2020 Jun 10.

Department of Biology, University of Southern Denmark, Odense, Denmark.

Cuttlefish are highly efficient predators, which strongly rely on their anterior binocular visual field for hunting and prey capture. Their complex eyes possess adaptations for low light conditions. Recently, it was discovered that they display camouflaging behavior at night, perhaps to avoid detection by predators, or to increase their nighttime hunting success. Read More

A "Global-Local" Visual Servo System for Picking Manipulators.

Sensors (Basel) 2020 Jun 14;20(12). Epub 2020 Jun 14.

College of Mechanical and Electronic Engineering, Northwest A&F University, Yangling 712100, China.

During the process of automated crop picking, the two hand-eye coordination operation systems, namely "eye to hand" and "eye in hand" have their respective advantages and disadvantages. It is challenging to simultaneously consider both the operational accuracy and the speed of a manipulator. In response to this problem, this study constructs a "global-local" visual servo picking system based on a prototype of a picking robot to provide a global field of vision (through binocular vision) and carry out the picking operation using the monocular visual servo.

Sensory loss due to object formation.

Vision Res 2020 Jun 7;174:22-40. Epub 2020 Jun 7.

Facebook Reality Labs, Redmond, WA 98052, USA.

The precision to locate individual features in depth can often be improved by integrating information over space. However, this integration can sometimes be extremely detrimental, as for example in the case of the Westheimer-McKee phenomenon where features are grouped to form an object. We replicate here the known loss of precision in this phenomenon and document an additional loss of accuracy. Read More

Abutting Objects Warp the Three-Dimensional Curvature of Modally Completing Surfaces.

Peter U Tse

Iperception 2020 Mar-Apr;11(2):2041669520903554. Epub 2020 Apr 9.

Department of Psychological and Brain Sciences, Dartmouth College, Hanover, New Hampshire, United States.

Binocular disparity can give rise to the perception of open surfaces or closed curved surfaces (volumes) that appear to vary smoothly across discrete depths. Here I build on my recent papers by providing examples where modally completing surfaces not only fill in from one depth layer's visible contours to another layer's visible contours within virtual contours in an analog manner, but where modally completing surface curvature is altered by the interpolation of an abutting object perceived to be connected to or embedded within that modally completing surface. Seemingly minor changes in such an abutting object can flip the interpretation of distal regions, for example, turning a distant (where a surface ends) into (where a surface bends to occlude itself) or turning an open surface into a closed one.

Technical Report: Repeatability of Contrast Sensitivity Test in Children.

Optom Vis Sci 2020 Jun;97(6):400-405

Department of Optics and Optometry and Vision Sciences, University of Valencia, Valencia, Spain.

Contrast sensitivity (CS) in children is not routinely measured in the clinical setting, although CS losses have been found in amblyopic and premature children. Thus simple visual acuity measurements do not completely assess their quality of vision. To evaluate contrast sensitivity in children, a reliable and easy test, sampling the entire spatial frequency range, is necessary. Read More

Brain Activation for Audiovisual Information in People With One Eye Compared to Binocular and Eye-Patched Viewing Controls.

Front Neurosci 2020 21;14:529. Epub 2020 May 21.

Department of Psychology, York University, Toronto, ON, Canada.

Blindness caused by early vision loss results in complete visual deprivation and subsequent changes in the use of the remaining intact senses. We have also observed adaptive plasticity in the case of partial visual deprivation. The removal of one eye, through unilateral eye enucleation, results in partial visual deprivation and is a unique model for examining the consequences of the loss of binocularity. Read More

Predicting stereopsis in macular degeneration.

J Neurosci 2020 Jun 2. Epub 2020 Jun 2.

Smith-Kettlewell Eye Research Institute, San Francisco, CA, 94115 USA.

Each of our eyes sees a slightly different view of the physical world. Disparity is the small difference in position of features in the retinal images; stereopsis is the percept of depth from disparity. A distance between corresponding features in the retinal images of the two eyes smaller than the "upper disparity limit" yields a percept of depth; distances greater than this limit cause the two unfused monocular features to appear flattened into the fixation plane.

Are new vision standards and tests needed for military aircrew using 3D stereo helmet-mounted displays?

BMJ Mil Health 2020 May 30. Epub 2020 May 30.

Operational Based Vision Assessment (OBVA) laboratory, 711th HPW, Wright-Patterson AFB, Ohio, USA.

Visual standards for military aviators were historically set in the 1920s with requirements based on the visual systems of aircraft at the time, and these standards have changed very little despite significant advances in aircraft technology. Helmet-mounted displays (HMDs) today enable pilots to keep their head out of the cockpit while flying and can be monocular, biocular or binocular in design. With next generation binocular HMDs, flight data can be displayed in three-dimensional stereo to declutter information presented, improving search times and potentially improve overall performance further.

Department of Psychology, Northeastern University, United States.

In the phenomenon of simultaneous brightness contrast, two patches, one on a dark background and the other on a light one, appear to have different brightness despite being physically equi-luminant. Elucidating the phenomenon's underlying mechanisms is relevant for the larger question of how the visual system makes photometric judgments in images. Accounts over the past century have spanned low-, mid- and high-level visual processes, but a definitive resolution has not emerged. Read More

The adult visual system was traditionally thought to be relatively hard-wired, but recent studies have challenged this view by demonstrating plasticity following short-term monocular deprivation. Depriving one eye of spatial information for 2-3 h increased subsequent sensory dominance of that eye. However, the mechanism underlying this phenomenon is unclear. Read More

The endogenous neurotransmitter acetylcholine (ACh) is known to affect the excitatory/inhibitory (E/I) balance of primate visual cortex, enhancing feedforward thalamocortical gain while suppressing cortico-cortical synapses. Recent advances in the study of the human visual system suggest that ACh is a likely component underlying interocular interactions. However, our understanding of its precise role in binocular processes is currently lacking. Read More

Probing the mechanisms of probe-mediated binocular rivalry.

Vision Res 2020 Aug 20;173:21-28. Epub 2020 May 20.

Department of Psychology, University of Illinois at Urbana-Champaign, Champaign, IL 61820, USA; Beckman Institute for Advanced Science and Technology, University of Illinois at Urbana-Champaign, Urbana, IL 61801, USA.

Binocular rivalry occurs when incompatible images are presented simultaneously but separately to each eye. Perceptual dominance reverses over time such that one image temporarily dominates perception, while the other image is suppressed. Prior research has shown that briefly-presented probes modulate perception such that probes presented to the suppressed eye tend to produce shorter percept durations relative to when probes are presented to the dominant eye.

Longitudinal Changes in Optical Quality, Spatial Vision, and Depth Vision after Laser Refractive Surgery for Myopia.

Optom Vis Sci 2020 May;97(5):360-369

The Cornea Institute, L V Prasad Eye Institute, Hyderabad, Telangana, India.

Significance: Laser refractive surgery procedures are efficacious at correcting myopia, but they result in long-term deterioration of optical quality that affects monocular and binocular visual performance. The study shows that the optical quality of the two eyes needs to be similar to optimize binocular visual performance after surgery.

Purpose: This study aimed to systematically analyze longitudinal changes in optical quality, high- and low-contrast logMAR acuity and random-dot stereoacuity before and after three refractive surgery procedures for correcting myopia. Read More

Short-Term Deprivation Does Not Influence Monocular or Dichoptic Temporal Synchrony at Low Temporal Frequency.

Front Neurosci 2020 28;14:402. Epub 2020 Apr 28.

State Key Laboratory of Ophthalmology, Optometry and Vision Science, School of Ophthalmology and Optometry and Eye hospital, Wenzhou Medical University, Wenzhou, China.

Studies on binocular combination and rivalry show that short-term deprivation strengthens the contribution of the deprived eye in binocular vision. However, whether short-term monocular deprivation affects temporal processing is not clear. To address this issue, we conducted a study to investigate the effect of monocular deprivation on dichoptic temporal synchrony. Read More

Since Kepler (1604) and Descartes (1637), 'vergence' (the angular rotation of the eyes) has been thought of as one of our most important absolute distance cues. But vergence has never been tested as an absolute distance cue divorced from obvious confounding cues such as binocular disparity. In this article, we control for these confounding cues for the first time by gradually manipulating vergence and find that observers fail to accurately judge distance from vergence. Read More

Geometry constrained correlation adjustment for stereo reconstruction in 3D optical deformation measurements.

Opt Express 2020 Apr;28(8):12219-12232

Recovering the geometric shape of deformable objects from images is essential to optical three-dimensional (3D) deformation measurements and is also actively pursued by researchers. Most of the existing techniques retrieve the shape data with triangulation based on pre-estimated stereo correspondences. In this paper, we instead propose to recover depth information directly from images of a binocular vision system for 3D deformation estimation. Read More

High-speed and robust infrared-guiding multiuser eye localization system for autostereoscopic display.

Appl Opt 2020 May;59(14):4199-4208

In order to localize the viewers' eyes, a high-speed and robust infrared-guiding multiuser eye localization system was fabricated in this paper for a binocular autostereoscopic display, which can project a pair of parallax images to corresponding eyes. The system is composed of a low-resolution thermal infrared camera, a pair of high-resolution left and right visible spectral cameras, and an industrial computer. The infrared camera and the left visible spectral camera, and the left and right visible spectral camera, can both form the binocular vision system. Read More

Retinal Ganglion Cell Axon Wiring Establishing the Binocular Circuit.

Annu Rev Vis Sci 2020 May 12. Epub 2020 May 12.

Mortimer B. Zuckerman Mind Brain Behavior Institute, Columbia University, New York, NY 10027, USA; email:

Binocular vision depends on retinal ganglion cell (RGC) axon projection either to the same side or to the opposite of the brain. In this article, we review the molecular mechanisms for decussation of RGC axons, with a focus on axon guidance signaling the optic chiasm and ipsi- and contralateral axon organization in the optic tract prior to and during targeting. The spatial and temporal features of RGC neurogenesis that give rise to ipsilateral and contralateral identity are described. Read More

Graduate School of Information Science, Tohoku University, Sendai, Japan; Research Institute of Electrical Communication, Tohoku University, Sendai, Japan. Electronic address:

Perception of motion in depth is one of the most important visual functions for living in the three-dimensional world. Two binocular cues have been investigated for motion in depth: inter-ocular velocity difference (IOVD) and changing disparity (CD). IOVD provides direction information directly by comparing velocity signals from the two retinas. Read More

Polarization-sensitive optical coherence tomography for estimating relative melanin content of autologous induced stem-cell derived retinal pigment epithelium.

Sci Rep 2020 May 6;10(1):7656. Epub 2020 May 6.

Department of Ophthalmology, Kobe City Eye Hospital, Kobe, Hyogo, Japan.

Transplantation of autologous human induced pluripotent stem cell-derived retinal pigment epithelial (hiPSC-RPE) sheets is a promising therapy for age-related macular degeneration (AMD). As melanin content is a representative feature of healthy RPE, we used polarization-sensitive optical coherence tomography (PS-OCT) to estimate the relative melanin content of RPE in diseased and non-diseased area, and in human iPSC-RPE sheets in vitro and in vivo by evaluating the randomness of polarization (entropy). Two aged Japanese women, one with neovascular AMD that underwent transplantation of an autologous hiPSC-RPE cell sheet and another with binocular dry AMD, were selected for this study. Read More

The effect of monocular occlusion on hippocampal c-Fos expression in domestic chicks (Gallus gallus).

Sci Rep 2020 Apr 29;10(1):7205. Epub 2020 Apr 29.

Center for Mind/Brain Sciences, University of Trento, Trento, Italy.

In birds, like in mammals, the hippocampus is particularly sensitive to exposure to novel environments, a function that is based on visual input. Chicks' eyes are placed laterally and their optic fibers project mainly to the contralateral brain hemispheres, with only little direct interhemispheric coupling. Thus, monocular occlusion has been frequently used in chicks to document functional specialization of the two hemispheres. Read More
