To investigate amblyopic contrast vision at threshold and above we performed pedestal-masking (contrast discrimination) experiments with a group of eight strabismic amblyopes using horizontal sinusoidal gratings (mainly 3c/deg) in monocular, binocular and dichoptic configurations balanced across eye (i.e. five conditions). With some exceptions in some observers, the four main results were as fo...

With the advent of Micro‐LED technology, light source has been widely used in medical technology due to its unique superior performance. In field phototherapy, characteristics wide spectral range, good monochromaticity, low power consumption and high brightness, which become best choice for phototherapy technology. this paper, we analyze advantage optimized eye mask, mainly treating periocular ...

The visual world appears unified, stable, and continuous despite rapid changes in eye position. How this is accomplished has puzzled psychologists for over a century. One possibility is that visual information from successive eye fixations is fused in memory according to environmental or spatiotopic coordinates. Evidence supporting this hypothesis was provided by Davidson, Fox, and Dick (1973)....

: In normal population and patient, the significant increase in dry eyes manifestations have been observed. Similarly, aggravated symptoms complaints of dryness also observed clinical hospital staff by using a face mask for an extended time period. The purpose study was to observe association between duration masks health professionals. An unspecified questionnaire distributed Google Forms thro...

Using Hyper Suprime Camera data (a precursor of what is to come with Rubin Observatory) we assess trail masking mitigation strategies for satellite contamination. We examine HSC the Hubble COSMOS field where trails have been identified by eye. Exercising current LSST Science Pipelines on this data, study efficacy which appear in single visit exposures before they are assembled into a coadded fr...

the laryngeal mask airway (lma) is an important addition to the anesthetist's equipments. however, its usage may involve some complications. we have encountered an unusual and potentially serious complication using this equipment. a 45-year old man underwent cataract surgery under general anesthesia. after the induction of anesthesia, a size 4 of the reusable classic lma was inserted without an...

The retina has one of the highest oxygen consumptions of any tissue in the body [1] and this is mainly due to the photoreceptors and the rods in particular [2]. The rod consumption of oxygen is at its greatest when the retina is dark-adapted [3] and the rods generate dark current. At such time the choroid, the main vascular supply to the photoreceptors, is at its most sluggish and so greater de...

Several types of suppression phenomena have been observed in the visual system. For example, the ability to detect a target stimulus is often impaired when the target is embedded in a high-contrast surround. This contextual modulation, known as surround suppression, was formerly thought to occur only in the periphery. Another type of suppression phenomena is interocular suppression, in which th...
