PURPOSE To assess whether there are any advantages of binocular over monocular vision under blur conditions. METHODS The effect of defocus, induced by positive lenses, was measured on the pattern reversal visual evoked potential (VEP) and on visual acuity (VA). Monocular (dominant eye) and binocular VEPs were recorded from 13 volunteers (average age, 28 ± 5 years; average spherical equivalent...

Background: Some post-LASIK patients complain of blurry distance vision months after refractive surgery, despite good corneal healing and negligible refractive error. We postulated that perceiving blur in the absence of refractive error or significant monocular aberrations might result from poor binocular control. Binocular vision testing in a series of such patients revealed convergence proble...

OBJECTIVE To evaluate two cases of intermittent exotropia treated by vision therapy the efficacy of the treatment by complementing the clinical examination with a 3D videooculography to register and to evidence the potential applicability of this technology for such purpose. METHODS We report the binocular alignment changes occurring after vision therapy in a woman of 36 years with an intermi...

Transient visual loss due to cerebro-ocular vascular disease is a common symptom. The purpose of this paper is to present a unified terminology of the monocular vs. binocular or homonymous types. Lack of proper identification may lead to mis-diagnosis and improper management of these entities. Monocular blurred vision must be investigated since its origin is so commonly due to atherosclerosis o...

Deriving accurate 3-D motion information of a scene is an essential and important task in computer vision, and is also one of the most difficult problems. In this paper, using photogrammetry method and computer vision technique the author investigates the determination of 3-D motion parameters from binocular stereo image sequences method and steps. Discussing the in-situ calibration for binocul...

Abnormal early visual experience often leads to poor vision, a condition called amblyopia. Two recent approaches to treating amblyopia include binocular therapies and intensive visual training. These reflect the emerging view that amblyopia is a binocular deficit caused by increased neural noise and poor signal-in-noise integration. Most perceptual learning studies have used monocular training;...

Aiming at overcoming the shortcomings of current method of binocular measurement, namely, low accuracy in feature point matching, high computational complexity and narrow measurable range, this paper puts forward a new type of binocular stereo vision sensor with full sphere view composed of two ODVSs (omnidirectional vision sensor) with the same parameters in back-to-back configuration. The ODV...
