Progressive retinal atrophy (PRA) is a group of genetic diseases seen in certain breeds of dogs and, more rarely, cats. Similar to retinitis pigmentosa in humans, [1] it is characterized by the bilateral degeneration of the retina, causing progressive vision loss culminating in blindness. The condition in nearly all breeds is inherited as an ...
Photopsia is the presence of perceived flashes of light in the field of vision. It is most commonly associated with: [4] Vitreous shrinkage or liquefaction, which is the most common cause of photopsia, causes a pull in vitreoretinal attachments, irritating the retina and causing it to discharge electrical impulses.
Gene therapy for color blindness. Gene therapy for color blindness is an experimental gene therapy of the human retina aiming to grant typical trichromatic color vision to individuals with congenital color blindness by introducing typical alleles for opsin genes. Animal testing for gene therapy began in 2007 with a 2009 breakthrough in squirrel ...
Type 1 von Willebrand Disease in dogs. Type 1 von Willebrand Disease is the most common type, and also the mildest. It occurs when dogs have a mild deficiency in all the proteins making up their ...
Progressive retinal atrophy (PRA) is a genetic disease of the retina that occurs bilaterally and is seen in certain breeds of dogs. It causes progressive vision loss culminating in blindness. [63] Retinal dysplasia is an eye disease affecting the retina. It is usually a nonprogressive disease and can be caused by viral infections, drugs ...
According to professional dog trainer Elijah Boateng, your actions could be why your dog is anxious, and it's pretty eye-opening. At the beginning of September, he shared a video explaining what ...
Retinal detachment. Retinal detachment is a disorder of the eye in which the retina peels away from its underlying layer of support tissue. [1] Initial detachment may be localized, but without rapid treatment the entire retina may detach, leading to vision loss and blindness. It is a surgical emergency.
Dilute color dogs (Blue, Isabella, and Cream) are very susceptible to color dilution alopecia, a skin disorder that can result in hair loss and extreme sensitivity to sun. Since the occurrence and severity of these health problems is largely hereditary, breeders are working to eliminate these.
