Augmented-vision devices that we are developing to aid people with low vision (impaired vision) employ vision multiplexing- the simultaneous presentation of two different views to one or both eyes. This approach enables compensation for vision deficits without depriving the wearers of their normal views of the scene. Ideally, wearers would make use of the simultaneous views to alert them to pot...

PURPOSE To our knowledge, studies comparing binocular eye movements during reading task in strabismic children are scarce. The goal of our study was to examine binocular coordination of saccades during reading in strabismic children. METHODS Binocular eye movements were recorded by an infrared system (mobile EBT) in 18 strabismic children 6.8 to 16 years old (mean age 10.2 ± 3) who were asked...

BACKGROUND/AIM The aim of this study was to investigate the potential correlation between clinical characteristics and prognosis of patients with retinoblastoma (Rb). MATERIALS AND METHODS This retrospective study included 314 Rb patients. Clinical data including laterality of eyes, sex, age, presenting signs, lag time, and survival were recorded and analyzed. RESULTS Leukocoria is the most...

Butterfly eyes are random mosaics built of three ommatidia types, each with a different set of photoreceptors and pigments. What defines the combined features in each ommatidium? A new study has solved the puzzle.

Animals with front facing eyes benefit from a substantial overlap in the visual fields of each eye, and devote specialized brain processes to using the horizontal spatial disparities produced as a result of viewing the same object with two laterally placed eyes, to derived depth or 3-D stereo information. This provides the advantage to break the camouflage of objects in front of similarly textu...

In individuals with abnormal binocular vision, such as strabismics and anisometropes, it is common for all or part of one eye's view to be suppressed so binocular confusion and diplopia are eliminated. We examined the relation between the depth of suppression (the amount by which the monocular contrast increment threshold for an eye was elevated by stimulation in the contralateral eye) and the ...

Binocular vision is obviously useful for depth perception, but it might also enhance other components of visual processing, such as image segmentation. We used naturalistic images to determine whether giving an object a stereoscopic offset of 15-120 arcmin of crossed disparity relative to its background would make the object easier to recognize in briefly presented (33-133 ms), temporally maske...

The fusion of data provided by different sources of knowledge produces sensor systems showing higher robustness, signal to noise ratio, and adaptability. In the context of machine vision, a system can be designed as a group of indipendent visual modules acting as individual knowledge sources. An integration scheme is then needed to obtain a fused output. This text is a tutorial intended as an i...

R Vision therapy, also known as vision training, is a term used to define highly specific, sequential, sensory-motorperceptual stimulation paradigms and regimens that are used to improve vision skills, such as eye movement control and eye coordination.1 This training procedure can be performed in both home and office settings, but always under the professional supervision of an optometrist or a...

Over the past 20 years, there have been great strides made to identify individuals who may have experienced an mTBI, as this can be difficult in many cases where there is a sparse case history and vague symptoms, both of a general and visual nature. Hence, there has been the advent of more accurate, precise, objective and quantitative clinical and laboratory approaches for the detection and dia...
