The retina - The lens focuses light onto the photoreceptor cell of this innermost layer of the eye. (vetsci.co.uk)
There are a many diseases which can affect the retina. (vetsci.co.uk)
Retinal detachment is a disorder of the eye in which the retina peels away from its underlying layer of support tissue. (furrycritter.com)
The retina is a thin layer of light-sensitive tissue on the back wall of the eye. (furrycritter.com)
The optical system of the eye focuses light on the retina much like light is focused on the film in a camera. (furrycritter.com)
Occasionally, posterior vitreous detachment, injury or trauma to the eye or head may cause a small tear in the retina. (furrycritter.com)
Your veterinarian will do an eye examination using an ophthalmoscope where they will immediately notice that the retina is not where it is supposed to be. (furrycritter.com)
In some cases, a detached retina can occur as a complication during cataract surgery or other types of eye surgery. (furrycritter.com)
In dogs, the cause most often is a disease-related accumulation of fluid underneath the retina that separates it from the choroid. (furrycritter.com)
Therapy must be instituted as early in the disease process as possible, or the detached retina will deteriorate and the dog will be permanently blind. (furrycritter.com)
In this treatment, Adatomed Silicone Oil is a sterile, colorless liquid injected into the eye and mechanically holds the retina in place until it reattaches. (furrycritter.com)
The bands push the wall of the eye inward against the retinal hole, closing the hole and allowing the retina to re-attach. (furrycritter.com)
The ocular fundus is the back of the eye opposite the pupil and includes the retina, the membrane (the choroid) between the retina and the white of the eye, and the optic disk. (merckvetmanual.com)
Inherited abnormalities may be present at birth or appear later, and are important in the development of diseases of the retina in dogs. (merckvetmanual.com)
The main abnormality is an area of the choroid or the retina and choroid that fails to develop fully. (merckvetmanual.com)
More severely affected dogs may also have abnormalities close to where the optic nerve enters the eye, and some will have detachment of the retina. (merckvetmanual.com)

Immunocytochemistry of normal canine retina demonstrated specific localization of protein to the RPE basolateral plasma membranes. (upenn.edu)
CEA is more technically known as Choroidal Hypoplasia (CH). It is a recessively inherited eye disorder that causes abnormal development of the choroid - an important layer of tissue under the retina of the eye. (collie-online.com)
One of the first behavioral signs of inherited, degenerative diseases of the outer retina (commonly known as Progressive Retinal Atrophy, PRA) is loss of night vision as rods are affected before cones. (vin.com)
The problem in CEA is that an area of the retina (the nerve layer of the eye with rods and cones) and/or the choroid (the choroid is the blood vessel layer under the retina) does not develop the way it should because of DNA mutations. (vin.com)
It is possible for a retina to detach early or later in life, causing blindness in that eye. (vin.com)
The optics of the eye create a focused two-dimensional image of the visual world on the retina, which then processes that image within the retina and sends nerve impulses along the optic nerve to the visual cortex to create visual perception . (wikipedia.org)
therefore, the optic nerve must cross through the retina en route to the brain. (wikipedia.org)
The cephalopods have a non-inverted retina, which is comparable in resolving power to the eyes of many vertebrates. (wikipedia.org)
It affects the central area of the retina called the macula that is responsible for sharp, central (high resolution) vision. (homeopathy-ny.org)
The choroid is a fine network of blood vessels that feeds the retina. (life724.com)

Pecten - Birds contain an organ within their vitreous humour (the jelly-like substance which fills the eye cavity). (vetsci.co.uk)
Its outer surface is in contact with the choroid and the inner surface with the vitreous body. (lecturio.com)
These findings introduce fresh perspectives for the clinical management of unspecified vitreous disorders and contribute to the understanding of the effect of myopia on vitreous disorders. (bvsalud.org)
Myopia prevention and treatment will aid in slowing down the process of vitreous liquefaction and subsequently decrease the incidence of malignant eye conditions. (bvsalud.org)

Iris - Contains radial and circular smooth muscles which control the opening of the pupil to regulate the amount of light entering the eye and to prevent damage. (vetsci.co.uk)
Iris in the two eyes may be of different colors, heterochromia. (vin.com)

It is also known as eye inflammation among the people. (life724.com)
Although the causes of eye inflammation are unknown, it is estimated to be caused by infections (such as toxoplasma, HPV virus, tuberculosis), immune system diseases (such as psoriasis, MS, Behçet's disease) or blows to the eye. (life724.com)

In four of these cases, the cause of hyphema was trauma and remaining case was caused by phacoclastic uveitis in a dog with bilateral hypermature cataract. (scielo.br)
If uveitis is present, the effect of Tropicamide may be poor in the affected eye. (vin.com)
When the middle portion of the eye is inflamed, irritated, or infected, it is called uveitis. (topeyedoctorsnearme.com)
Uveitis is always an urgent condition requiring immediate treatment by an eye care professional for the best chance to protect and preserve eyesight. (topeyedoctorsnearme.com)
Intermediate uveitis means the ciliary body only is affected. (topeyedoctorsnearme.com)
When more than one eye layer is involved, such as both the anterior and intermediate layers, this type of uveitis is called diffuse uveitis. (topeyedoctorsnearme.com)

Two disease-specific sequence alterations were identified in the canine VMD2 gene: a C73T stop mutation in cmr1 and a G482A missense mutation in cmr2. (upenn.edu)
The authors propose these two spontaneous mutations in the canine VMD2 gene, which cause cmr, as the first naturally occurring animal model of BMD. (upenn.edu)
The dogs who have only one mutated gene for CEA from one parent do not have the disease and are called carriers. (vin.com)
The hereditary disease, whose causative mutation in the MYO5A gene is detected with the test, was initially called Griscelli type 1 analogue syndrome because of the analogy in humans. (generatio.de)
These markers are thought to be related to "domestication gene sweeps" where early dogs were selected for some trait. (embarkvet.com)

Until recently, the only way to know if a dog was a carrier was for it to produce an affected puppy. (wikipedia.org)
The test can determine whether a dog is affected, a carrier, or clear, and is therefore a useful tool in determining a particular dog's suitability for breeding. (wikipedia.org)
The chart below shows how the genotype of both parents contributes to diseases such as CEA, CL, TNS in their offspring depending on whether the parents are Normal / Clear, Carrier or Affected. (borderwoodkennel.com)
A genetic test is available to confirm the presence of the disease or identify carrier dogs that could pass the disease to their puppies. (merckvetmanual.com)
If a carrier is mated to a carrier, then 25 percent of the puppies will have the disease with two copies of the mutation, 50 percent will be carriers with one copy of the mutation, and 25 percent will be clear with no mutations. (vin.com)
The genetic test for CEA can determine all three genetic states of a normal carrier, and affected with 90-95% accuracy. (vin.com)
Unfortunately, dogs that appear normal may still be carriers for the CEA mutation, and breeding two carrier dogs to each other can still run the risk of producing 25% affected puppies and 50% carrier puppies. (vin.com)
