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.
Cherry eye in dogs can be a concerning condition as it can look very angry and uncomfortable. Many animals have three sets of eyelids (so do humans, but ours are much smaller) and the tear gland ...
This mass may be unilateral or ‘’bilateral’’. Both eyes may develop cherry eye at different times in the animal's life. [1] Other symptoms of cherry eye include drainage from the eye and abnormal tear production. Initially, cherry eye results in overproduction of tears, but eventually changes to unsubstantial tear production. [1]
Symptoms include eye redness, a yellow or greenish discharge, ulceration of the cornea, pigmented cornea, and blood vessels on the cornea. [ 63 ] Vogt–Koyanagi–Harada syndrome is a condition seen in dogs characterized by uveitis (inflammation of the inside of the eye), poliosis (whitening of hair), and vitiligo (loss of pigment in the skin).
Glaucoma in dogs is a painful condition caused by high pressure within the eye. Two types of glaucoma can affect our canine companions: primary and secondary. Glaucoma can lead to blindness if it ...
Symptoms include sudden permanent blindness, but may occur more slowly over several days, weeks or months, [3] dilated pupils. Pupillary light reflexes are usually reduced but present; the slow phase mediated by melanopsin in retinal ganglion cells is retained.
CDV does not affect humans. In canines, CDV affects several body systems, including the gastrointestinal and respiratory tracts, the spinal cord, and the brain. Common symptoms include high fever, eye inflammation and eye/nose discharge, labored breathing and coughing, vomiting and diarrhea, loss of appetite and lethargy , and hardening of the ...
The canine distemper vaccination in particular has been a suspected causal factor due to the significant number of overlapping symptoms observed between systemically affected HOD puppies and dogs suffering from distemper, [9] but to-date, no definitive linkage has been demonstrated. [10] The cause of canine HOD largely remains unknown.
