RESTORATION OF BINOCULAR VISION IN AMBLYOPIA
A new procedure is described to measure and reduce the extent to which the fixating eye suppresses the amblyopic eye in adults with amblyopia. We assume that suppression creates a structurally binocular, functionally monocular system.
DICHOPTIC TRAINING ENABLES THE ADULT AMBLYOPIC BRAIN TO LEARN
Adults with amblyopia, a common disorder of the visual cortex primarily caused by binocular disruption during a critical early period, do not respond to conventional therapy that involves occlusion of one eye. Here we provide direct evidence that reducing suppression of the amblyopic eye through the presentation of dichoptic stimuli induces higher levels of plasticity than the forced use of the amblyopic eye alone.
IMPROVED BINOCULAR OUTCOMES FOLLOWING BINOCULAR TREATMENT FOR CHILDHOOD AMBLYOPIA
Childhood amblyopia can be treated with binocular games or films that rebalance the contrast between the eyes, which is believed to reduce the depth of interocular suppression so that the child can experience binocular vision.
BINOCULAR IPad TREATMENT FOR AMBLYOPIA IN PRESCHOOL CHILDREN
Recent experimental evidence supports the role of binocular visual experience in the treatment of amblyopia. The purpose of this study was to determine whether repeated binocular experience with dichoptic games for iPad could effectively treat amblyopia in preschool-aged children.
THE EFFECT OF BANGERTER FILTERS ON BINOCULAR FUNCTION IN OBSERVERS WITH AMBLYOPIA
Evaluate whether partial occlusion of the non-amblyopic eye with Bangerter filters can immediately reduce suppression and promote binocular contrast summation in observers with amblyopia.

VISION IN AUTISM SPECTRUM DISORDERS
Autism Spectrum Disorders (ASD) are developmental disorders that are believed to primarily affect social functioning. However, there is now increasing evidence that unusual sensory processing is at least concomitant and possibly the cause of many of the behavioral signs and symptoms of ASD. A comprehensive and critical review of the phenomenological, empirical, neuroscientific, and theoretical literature on visual processing in ASD is presented.
VISUAL IMPAIRMENT AND TRAITSO OF AUTISM IN CHILDREN
Visual impairment present from birth or early childhood can lead to psychosocial and emotional disorders. Between 11% and 40% of children in the visual impairment group show traits of autism.
Continue ReadingREDUCED CHROMATIC DISCRIMINATION IN CHILDREN WITH AUTISM SPECTRUM DISORDERS
Relatively little is known about color perception in ASD. The current research evaluated color discrimination in children with high-functioning autism (HFA) and typically developing (TD) children.
NEAR-POINT FINDINGS IN CHILDREN WITH AUTISM SPECTRUM DISORDER AND IN TYPICAL PEERS
Children with autism spectrum disorder are more likely to show a retracted near point of convergence, poor fixation, inaccurate saccadic movements, erratic searches, and exophoric posture. These differences occur regardless of the reported level of verbal communication.
Continue ReadingVISION CONCERNS AFTER MILD TRAUMATIC BRAIN INJURY
Minor traumatic brain injury (mTBI) can manifest with visual dysfunction that includes accommodation deficits, vergence movements, versions, and visual field, as well as increased photosensitivity and a decrease in ocular and general health.
THE RELATIONSHIP BETWEEN CONVERGE
Children who are evaluated for attention deficit hyperactivity disorder (ADHD) often undergo a visual examination as part of their assessment. Symptoms of convergence insufficiency (CI) can make it difficult for a student to focus on extended reading and may overlap with those of ADHD.
ADHD AND VISION PROBLEMS IN THE NATIONAL SURVEY OF CHILDREN'S HEALTH
Compare the prevalence of attention-deficit/hyperactivity disorder (ADHD) in children with normal vision and those with vision problems or correctable with glasses or contact lenses (visual problems) as determined by parent reports in a national telephone survey.
ACADEMIC BEHAVIORS IN CHILDREN WITH CONVERGENCE INSUFFICIENCY WITH PARENT-REPORTED ADHD
Determine if children with symptomatic convergence insufficiency (CI) without the presence of attention deficit hyperactivity disorder (ADHD) reported by parents have higher scores on the academic behavior survey (ABS).
IMPROVEMENT OF VERGENCE MOVEMENTS BY VISION THERAPY DECREASES K-ARS SCORES SYMPTOMATIC ADHD CHILDREN
Determine whether improving vergence movements through visual therapy can reduce K-ARS scores in symptomatic children with ADHD.
AMPLYOPIA AND THE BINOCULAR APPROACH TO ITS THERAPY
There is increasing evidence that abnormal binocular interactions play a key role in amblyopia. In particular, stronger suppression of the amblyopic eye has been associated with poorer visual acuity of the amblyopic eye, and a new therapy has been described that directly targets binocular function and has been found to improve both monocular and binocular vision in adults and children with amblyopia.
A NEW BINOCULAR APPROACH TO THE TREATMENT OF AMBLYOPIA IN ADULTS WELL BEYOND THE CRITICAL PERIOD OFVISUAL THERAPY
The current treatments for amblyopia are predominantly monocular, aiming to improve vision in the amblyopic eye by patching the fixating eye or through visual training of the amblyopic eye. This approach is problematic, especially because it rarely results in the establishment of binocular function. Recently, it has been shown that amblyopes possess binocular cortical mechanisms for both threshold and supra-threshold stimuli.
EFFECTS OF STRABISMIC AMBLYOPIA AND STRABISMUS WIHOUT AMBLYOPIA ON VISUOMOTOR BEHAVIOR, I: SACCADIC EYE MOVEMENTS
PART I: SACCADIC MOVEMENTS The objective of this study was to investigate the impact of strabismic amblyopia on saccadic performance.
PART II. VISUALLY GUIDED REACH
Examine the effects of impaired spatiotemporal vision on reaching movements in participants with strabismic amblyopia and compare their performance with those with strabismus only without amblyopia and with visually normal participants.
PART III. TEMPORAL EYE-HAND COORDINATION DURING REACHING
Examine the effects of strabismic amblyopia and strabismus alone, without amblyopia, on the temporal patterns of eye-hand coordination during the planning and execution stages of visually guided reaching.
EFFECTS OF REDUCED ACUITY AND STEREO ACUITY ON SACCADES AND REACHING MOVEMENTS IN ADULTS WITH AMBLYOPIA AND STRABISMUS
Our previous work has shown that amblyopia disrupts the planning and execution of saccadic movements and visually guided reaching. We investigated the association between the clinical characteristics of amblyopia and the aspects of visuomotor behavior that are affected by amblyopia.
ORIGINS OF STRABISMUS AN LOSS OF BINOCULAR VISION
Strabismus is a common eye disorder that develops early in humans. As a general rule, it is characterized by a misalignment of the visual axes that occurs most frequently during the critical period of visual development. However, other characteristics of strabismus can vary widely among individuals.
INTERVENTIONS FOR INFANTILE ESOTROPIA
Childhood Esotropia (CE) is the inward deviation of the eye. Several aspects of the clinical management of CE are unclear; primarily, the most effective type of intervention and the age of intervention.
INTERVENTIONS FOR INTERMITTENT EXOTROPIA
The clinical management of Intermittent Exotropia has been widely discussed in the literature. However, there remains a lack of clarity regarding the indications for intervention, the most effective form of treatment, and whether there is an optimal time in the progression of the disease when treatment should be carried out.
RATES OF REOPERATION AND ABNORMAL BINOCULARITY FOLLOWING STRABISMUS SURGERY IN CHILDREN
Determine predictions of reoperation and abnormal binocular outcomes (including amblyopia and diplopia) after pediatric strabismus surgery.
BOTULINUM TOXIN FOR THE TREATMENT OF STRABISMUS
The use of botulinum toxin as a research and treatment modality for strabismus is well documented in the medical literature. However, its effectiveness compared to other treatment options for strabismus is not clear.
