Although there are no rod/cone photoreceptors in the optic disc corresponding to the blind spot in the visual field, the performance of light detection decreases when another light stimulation is directly applied to the blind spot (Saito et al., VSS2019). Both scattered light outside the blind...
An arcuate visual field defect connecting to the blind spot indicates that the lesion results from the damage to the nerve fiber bundle extending from the optic disc. How can we determine whether this damage is the manifestation of the acute phase of ischemic optic neuropathy (ION) or normal ...
Blind spots are an area in which one is not able to see or perceive. One can find a blind spot by closing one eye and looking at a photo with a plus sign on a green background on the left side and a dot on a yellow background on the right. When you move in towards this the...

Somatic copy number alterations (SCNAs) are pervasive in advanced human cancers, but their prevalence and spatial distribution in early-stage, localized tumors and their surrounding normal tissues are poorly characterized. Here, we perform multi-region, single-cell DNA sequencing to characterize the SC...
I've found a video in YouTube: CUSTOM Windows 10 Boot Logo! [How To]! https://youtu.be/BfNw5cKY6qI How about this? ___ AshidacchiSaturday, November 9, 2019 3:51 PMJust a comment here. I got to this thread because I wanted to do the same thing: replace the Lenovo "splash ...
G6PD status in the field was diagnosed initially using the fluorescent spot test (FST) to allow for the allocation of SLDPQ (see Randomisation below). The qualitative, Carestart® (AccessBio, Somerset, NJ), rapid diagnostic test (RDT) was assessed in parallel. Both tests detect reliably ...
The normal representation of the visual field, including the monocular temporal crescent, has been determined. It has also been shown that there is a cellular discontinuity in lamina A which corresponds to the blind spot or optic disc. In normal cats four geniculate layers receive retinogeniculate ...
Corresponding visual field defects were determined with the Octopus perimeter (G1, peridata). The subjects were 28 controls and 34 glaucoma patients with visual field losses and papillometric defects. RESULTS: Amplitudes of nasal retinal areas (which include the blind spot) are smaller than those ...
