Collie eye anomaly (CEA) is a congenital, inherited, bilateral eye disease of dogs, which affects the retina, choroid, and sclera. It can be a mild disease or cause blindness. CEA is caused by a simple autosomal recessive gene defect. There is no treatment.
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, it is characterized by the bilateral degeneration of the retina, causing progressive vision loss culminating in blindness.
Sudden acquired retinal degeneration syndrome (SARDS) is a disease in dogs causing sudden blindness. It can occur in any breed, but female dogs may be predisposed. Approximately 4000 cases are seen in the United States annually.
Retinal detachment occurs with complete retinal dysplasia, and is accompanied by blindness in that eye. Cataracts or glaucoma can also occur secondary to retinal dysplasia. Other causes of retinal dysplasia in dogs include infection with canine adenovirus or canine herpesvirus, or radiation of the eye in newborns.
More Reasons Dogs Stare at Humans. I thought that Steve's caption was also interesting. "They learn quickly how a human moves, what their energy is, and what behaviors are associated with it. For ...
Glaucoma in a dog Canine glaucoma refers to a group of diseases in dogs that affect the optic nerve and involve a loss of retinal ganglion cells in a characteristic pattern. An intraocular pressure greater than 22 mmHg (2.9 kPa) is a significant risk factor for the development of glaucoma.
Florida keratopathy, also known as Florida spots, is an eye condition characterized by the presence of multiple spots within both corneas. It is most commonly seen in dogs and cats, but is also rarely seen in horses and birds. The disease is found in the southeastern parts of the United States.
Corneal dystrophy in dogs usually does not cause any problems and treatment is not required. [2] Suboptimal vision caused by corneal dystrophy usually requires surgical intervention in the form of corneal transplantation. Penetrating keratoplasty is commonly performed for extensive corneal dystrophy.
KCS is not common in dogs, affecting one per cent of the dog population. KCS is a chronic degenerative conjunctivitis that can lead to impaired vision and blindness. KCS has a wide array of causes including drug toxicity, cherry eye, previous surgery, trauma, and irradiation.
Ectopia lentis in dogs and cats. Although observed in humans and cats, ectopia lentis is most commonly seen in dogs. Ciliary zonules normally hold the lens in place. Abnormal development of these zonules can lead to primary ectopia lentis, usually a bilateral condition.
