In the first example, it has been noted that when conducting the PCT, this patient wore correction, was fixing left and has a twelve prism dioptre exotropia in the distance. At near they have a larger exotropic deviation measuring 18 prism dioptres. They also have a right hypertropia of six prism dioptres. This means that when the PCT was ...
Correction of refractive errors by glasses; Prism therapy (if tolerated, to manage diplopia) Vision Therapy; Patching (mainly to manage amblyopia in children and diplopia in adults) Botulinum toxin injection; Surgical correction; Surgical correction of the hypertropia is desired to achieve binocularity, manage diplopia and/or correct the ...
Prism dioptres. Prism correction is commonly specified in prism dioptres, a unit of angular measurement that is loosely related to the dioptre. Prism dioptres are represented by the Greek symbol delta (Δ) in superscript. A prism of power 1 Δ would produce 1 unit of displacement for an object held 100 units from the prism. [2]
Cyclotropia is a form of strabismus in which, compared to the correct positioning of the eyes, there is a torsion of one eye (or both) about the eye's visual axis. Consequently, the visual fields of the two eyes appear tilted relative to each other. The corresponding latent condition – a condition in which torsion occurs only in the absence ...
Purpose. extent of binocular functions. Bagolini striated glasses test, or BSGT, is a subjective clinical test to detect the presence or extent of binocular functions and is generally performed by an optometrist or orthoptist or ophthalmologist (medical/surgical eye doctor). It is mainly used in strabismus clinics.
The Genesis uses a 12.4 megapixel CCD chip, arranged in a 5760x2160 horizontally RGB filtered array. The resolution is resampled by pixel binning to a final output pixel resolution of 1920x1080. The chip has a 16:9 (1.78:1) aspect ratio, similar in size to Super 35 3-Perf film. The CCD active area is .930 in. x .523 in.
The extra pixels are used to form the increased area to the sides of the D1 image. The pixel density of 960H is identical to standard D1 resolution so it does not give any improvement in image quality, merely a wider aspect ratio. Alternative analog video transport technologies carrying higher resolutions than 960H include HD-TVI, HDCVI, and AHD.
1920 × 1080 (FHD) FHD ( Full HD) is the resolution used by the 1080p and 1080i HDTV video formats. It has a 16:9 aspect ratio and 2,073,600 total pixels, i.e. very close to 2 megapixels, and is exactly 50% larger than 720p HD ( 1280 × 720) in each dimension for a total of 2.25 times as many pixels.
Prism adaptation. Prism adaptation is a sensory-motor adaptation that occurs after the visual field has been artificially shifted laterally or vertically. It was first introduced by Hermann von Helmholtz in late 19th-century Germany as supportive evidence for his perceptual learning theory (Helmholtz, 1909/1962). [1]
Video super-resolution (VSR) is the process of generating high-resolution video frames from the given low-resolution video frames. Unlike single-image super-resolution (SISR) , the main goal is not only to restore more fine details while saving coarse ones, but also to preserve motion consistency.
