RNFL asymmetry has been proposed as a strong indicator of optic neuritis, [7] [8] with one small study proposing that asymmetry of 5–6μm was "a robust structural threshold for identifying the presence of a unilateral optic nerve lesion in MS." [9] Optic neuritis is often associated with multiple sclerosis, and RNFL data may indicate the pace ...
The GDx nerve fiber analyzers measure the retinal nerve fiber layer (RNFL) thickness with a scanning laser polarimeter based on the birefringent properties of the RNFL. Measurement is obtained from a band 1.75 disc diameters concentric to the disc. It projects a polarized beam of a light into the eye.
Dog anatomy comprises the anatomical study of the visible parts of the body of a domestic dog. Details of structures vary tremendously from breed to breed, more than in any other animal species, wild or domesticated, [ 1 ] as dogs are highly variable in height and weight.
A Stanford University School of Medicine study published in Science in October, 2007 found the genetics that explain coat colors in other mammals such as in horse coats and in cat coats, did not apply to dogs. [1] The project took samples from 38 different breeds to find the gene (a beta defensin gene) responsible for dog coat color. One ...
The lower the score, the less the degree of dysplasia present. The minimum (best) score for each hip is zero, and the maximum (worst) is 53, giving a range for the total of 0 to 106. Each hip is scored separately under the BVA, so within the UK scores are usually displayed as two numbers separated by a forward slash (e.g. 2/6).

To help cats and dogs stay calm during Thanksgiving, offer them a private, comfortable space in the house that they can retreat to if things get overwhelming. Show comments Advertisement
At sexual maturity, mudpuppies can be 20 cm (8 in) long and continue to grow to an average length of 33 cm (13 in), though specimens up to 43.5 cm (17.1 in) have been reported. [7] Their external gills resemble ostrich plumes and their size depends on the oxygen levels present in the water.
