Short-term monocular deprivation strengthens the contribution of the deprived eye to binocular vision. This change has been observed in adults with normal vision or amblyopia. The change in ocular dominance is transient and recovers over approximately one hour. This shift has been measured with various visual tasks, including binocular rivalry and binocular combination. We investigated whether the ocular dominance shift could be accumulated across multiple periods of monocular deprivation over consecutive days. We used a binocular phase combination task to measure the shift in eye dominance. We patched the dominant eye of ten adults with normal vision for two hours across five consecutive days. Our results show no cumulative effect after repeated sessions of short-term monocular deprivation.

Ocular dominance plasticity is a well-documented phenomenon allowing us to study properties of cortical maturation. Understanding this maturation might be an important step towards unravelling how cor...
There is convincing evidence that the deprivation of one sense can lead to adaptive neuronal changes in spared primary sensory cortices. However, the repercussions of late-onset sensory deprivations o...
In recent years, evidence has accumulated that non-Mendelian transgenerational inheritance of qualities acquired through experience is possible. In particular, it has been shown that raising rodents i...
A few hours of monocular patching temporarily enhances the deprived eye's contribution to binocular vision, constituting a form of adult brain plasticity. Although the mechanism for this plasticity is...
During critical period, the heightened plasticity in neocortex opens a time window when, with proper external environmental stimuli, experience dependent refinement processes help to optimize the func...

To evaluate the effectiveness of enhanced binocular amblyopia treatments in achieving a more complete and stable recovery.
There are indications in the literature that binocular vision disorders may occur after cataract and corneal refractive surgery. It is not clear whether these problems are new or represent...
Amblyopia is an impairment in spatial vision caused by asymmetry in the quality of visual input across the two eyes during childhood. It is difficult to treat in adulthood because the visu...
Prospective, randomised, controlled, single-surgeon, single-center clinical study to compare the clinical outcomes of two trifocal IOLs differing in the dominance of additional power. The ...
The functional superiority and preferential use of one eye over the other. The term is usually applied to superiority in sighting (VISUAL PERCEPTION) or motor task but not difference in VISUAL ACUITY or dysfunction of one of the eyes. Ocular dominance can be modified by visual input and NEUROTROPHIC FACTORS.
The study and treatment of defects in binocular vision resulting from defects in the optic musculature or of faulty visual habits. It involves a technique of eye exercises designed to correct the visual axes of eyes not properly coordinated for binocular vision.
Social structure of a group as it relates to the relative social rank of dominance status of its members. (APA, Thesaurus of Psychological Index Terms, 8th ed.)
The observation and analysis of movements in a task with an emphasis on the amount of time required to perform the task.
Ocular manifestations secondary to various NEOPLASMS in which antibodies to antigens of the primary tumor cross-react with ocular antigens. This autoimmune response often leads to visual loss and other ocular dysfunctions.
