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. Untreated glaucoma in dogs leads to permanent damage of the optic nerve ...
Sudden acquired retinal degeneration syndrome. 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. [1] Approximately 4000 cases are seen in the United States annually. [2]
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 ...
Scintillating scotoma is a common visual aura that was first described by 19th-century physician Hubert Airy (1838–1903). Originating from the brain, it may precede a migraine headache, but can also occur acephalgically (without headache), also known as visual migraine or migraine aura. [4]
Collie eye anomaly. 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.
Retinal dysplasia. Retinal dysplasia is an eye disease affecting the retina of animals and, less commonly, humans. It is usually a nonprogressive disease and can be caused by viral infections, drugs, vitamin A deficiency, or genetic defects. Retinal dysplasia is characterized by folds or rosettes (round clumps) of the retinal tissue.
Florida keratopathy. Florida keratopathy, also known as Florida spots, is an eye condition characterized by the presence of multiple spots within both corneas. [1] It is most commonly seen in dogs and cats, but is also rarely seen in horses and birds. [2] The disease is found in the southeastern parts of the United States. [2]
Asteroid hyalosis is a degenerative condition of the eye involving small white opacities in the vitreous humor. [1] It is known to occur in humans, dogs, cats, horses, and chinchillas. [2] Clinically, these opacities are quite refractile, giving the appearance of stars shining in the night sky—except that ocular asteroids are often quite mobile.
Corneal endothelial dystrophy is an age-related change that affects the inner layer of the corneal, the endothelium. Leakage of fluid into the cornea causes edema, causing a bluish appearance. This will eventually involve the whole cornea. Bullous keratopathy ( blisters in the cornea) may also form, leading to nonhealing and recurrent corneal ...
Blindness in animals. Visual perception in animals plays an important role in the animal kingdom, most importantly for the identification of food sources and avoidance of predators. For this reason, blindness in animals is a unique topic of study. In general, nocturnal or subterranean animals have less interest in the visual world, and depend ...
