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.
The frequency range of dog hearing is between 16–40 Hz (compared to 20–70 Hz for humans) and up to 45–60 kHz (compared to 13–20 kHz for humans), which means that dogs can detect sounds beyond the upper limit of the human auditory spectrum.
Canine terminology in this article refers only to dog terminology, specialized terms describing the characteristics of various external parts of the domestic dog, as well as terms for structure, movement, and temperament. This terminology is not typically used for any of the wild species or subspecies of wild wolves, foxes, coyotes, dholes ...
A dog with degenerative myelopathy often stands with its legs close together and may not correct an unusual foot position due to a lack of conscious proprioception. Canine degenerative myelopathy, also known as chronic degenerative radiculomyelopathy, is an incurable, progressive disease of the canine spinal cord that is similar in many ways to amyotrophic lateral sclerosis (ALS).
Although dog treats carry high benefits for dogs' teeth, they can also be a source of problems like obesity when given excessively, especially human table scraps. The type of food given directly affects the tendency of a dog to become overweight. Table scraps, treats, and even premium high-energy dog foods can contribute to obesity. [68]
A relaxed dog will display upward ear position, with the tail positioned downward. [1] In comparison, an anxious or fearful dog will display a tense body posture, backward position of the ears, head turning, and/or lip smacking. The tail may also be tucked between the hind legs.
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).
