Cherry eye is a disorder of the nictitating membrane (NM), also called the third eyelid, present in the eyes of dogs and cats. [ 1] Cherry eye is most often seen in young dogs under the age of two. [ 2] Common misnomers include adenitis, hyperplasia, adenoma of the gland of the third eyelid; however, cherry eye is not caused by hyperplasia ...
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 ...
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]
Some canine breeds are genetically more likely to develop eyelid problems, such as dogs with shortened muzzles and flattened faces — think boxers, Boston terriers, French bulldogs, Pekingese ...
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.
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 ...
A dog with cataracts. Canine cataracts are a prevalent cause of visual loss in dogs, frequently resulting in blindness. Cataracts typically occur when proteins break down in the lens of a dog's eye and clump together, obstructing the passage of light. [1] [2] There are several reasons cataracts may occur in dogs, such as heredity, trauma, aging ...
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.
