Structural Integrity of Eyes Diagnosed with Amblyopia. The measurement of retinal structure in amblyopia using Optical Coherence Tomography.
Amblyopia is the leading cause of monocular visual impairment in children. Therapy for amblyopia is extremely beneficial in some children but ineffective in others. It is critical that the reasons for this discrepancy are understood. Emerging evidence indicates that current clinical protocols for …

The functional impact of amblyopia and its associated conditions : an investigation of the potential disability associated with amblyopia and its associated conditions.
… has been paid to examination of the impact of amblyopia, and strabismus, upon the lives of the individuals. Although an extensive amount of literature exists regarding amblyopia and its associated visual defects, little is known about the contribution of the amblyopic eye in the habitual …

Low- and high-level motion deficits in amblyopia: studies of maximum motion displacement
… of motion and form perception, respectively. Amblyopia is a developmental condition which may affect an otherwise healthy eye if it experiences abnormal visual stimulation due to ocular misalignment (strabismus), unequal refractive errors (anisometropia), or both. Amblyopia has been associated …

Aniseikonia: A Potential Barrier To Neural Plasticity
… visual outcomes in children with anisometropic amblyopia. Full refractive correction is the initial treatment for amblyopia, which corrects image focus, but image size differences are often neglected. We aimed to identify the potential impact of aniseikonia by investigating current treatment …

The Effect of SSRIs on Adult Human Visual Cortex Plasticity. Do SSRIs Affect learning?
… In the second experiment, adults with amblyopia (n = 7) participated in a crossover study whereby placebo and citalopram were each combined with two weeks of occlusion therapy. Visual acuity (VA), stereopsis, electroretinograms and visual evoked potentials (VEPs) were measured …

School vision screening programmes: the benefits of including measurements of refractive error.
… literature is now available on the detection of amblyopia in vision screening programmes. However, little attention has been paid to the role of detecting refractive error namely hyperopia thus far. The purpose of this thesis was to determine the benefits of including a refractive error …

Perceptual learning in foveal and peripheral contrast discrimination: exploring the effects of stimuli on learning and the effects of learning on spatial vision
… is predominant in the normal periphery and in amblyopia. Perceptual learning has been shown to improve spatial vision in amblyopia but has not previously been employed to investigate crowding in amblyopia. The purpose of this work was to investigate the effect of surrounding stimuli parameters …

Interocular suppression and contrast gain control in human vision
… and test. Finally, contrast vision in strabismic amblyopia was investigated. Although amblyopes are generally believed to have impaired binocular vision, binocular summation was shown to be intact when stimuli were normalized for interocular sensitivity differences. An alternative account of …

The Development of the Functional Dissociation of Perception and Action
… The second study investigates children with amblyopia, a developmental visual disorder, and finds a reduced perception-action functional dissociation compared to neurotypical controls. This suggests that atypical visual experience disrupts the functional specialization of the pathways early …

Assessment of Stereoacuity in Patients with Strabismus
… stereotest, and Lang stereotest. Patients with amblyopia or previous ocular surgery were excluded. RESULTS: Ninety-four patients with intermittent exotropia and thirty-six patients with refractive accommodative esotropia were included, and mean age was 7.2 years (4.0-13.9). Mean stereoacuity in …

Duane's retraction syndrome in a cohort of South African children a 20 year clinic based review
… 88 (93,6%) were hyperopic and 6 (6.4%) myopic. Amblyopia was present in 15 (12.5%). Surgery was performed in 41(34%). CONCLUSION: This study is the first to provide robust data on the profile of paediatric DRS in the 3 main South African ethnic groups, and shows clear ethnic differences in DRS. …

Visual Function in New Zealand Children: from Preschool to Primary School

Development of the ocular motor system in mouse embryos
… in the ocular system leads to strabismus, amblyopia, and impaired vision. Strabismus alone affects up to 2% of the population, and studies have shown that it greatly affects self-image, employment, and public perception. Studying the development of the ocular motor system can help identify …

Understanding experience-dependent plasticity of cellular and network activity in the mouse primary visual cortex
… deprivation (MD). Here, we used a mouse model of amblyopia and revealed that juvenile OD plasticity, which manifests as depression of response to the deprived eye, requires expression of an immediate early gene, Arc. Also, the juvenile OD shift requires the activity of N-methyl-D-aspartate (NMDA) …
