Impact of type 1 diabetes on binocular vision: Evidence from a comparative analysis. [PDF]

Ann N Y Acad Sci
Individuals with type 1 diabetes (T1D) without retinopathy exhibit significant impairments in binocular vision, including reduced near point of convergence, fusional vergence, vergence facility, and AC/A ratio. The prevalence of non‐strabismic binocular vision disorders is higher in T1D, emphasizing the need for comprehensive optometric evaluations ...

Effectiveness of Vision Therapy for Binocular Single Vision Anomalies

International Journal of Latest Technology in Engineering Management & Applied Science
Abstract Background: Binocular single vision is the ability to maintain visual focus on an object with both eyes, resulting in a single visual image. Anomalies in this system can cause various visual symptoms and impact daily activities such as reading, driving, and using a computer. Despite the abundance of available data, there is a significant lack

Objective evaluation of fusional vergence after a vision therapy protocol in typical binocular vision. [PDF]

Ophthalmic Physiol Opt
Abstract Introduction Vision therapy is an effective treatment option for binocular vision and accommodative anomalies. However, its effect on typical binocular vision is less documented. The aim of this study was to evaluate objectively the change in near fusional vergence amplitudes in adults with typical binocular vision after performing a vision ...

Scaffolding depth cues and perceptual learning in VR to train stereovision: a proof of concept pilot study

Scientific Reports, 2021
Stereopsis is a valuable feature of human visual perception, which may be impaired or absent in amblyopia and/or strabismus but can be improved through perceptual learning (PL) and videogames.
