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 ...
Ocular hypertension. Ocular hypertension is the presence of elevated fluid pressure inside the eye ( intraocular pressure ), usually with no optic nerve damage or visual field loss. [1] [2] For most individuals, the normal range of intraocular pressure is between 10 mmHg and 21 mmHg. [3] [4] Elevated intraocular pressure is an important risk ...
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]
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 ...
Glaucoma is a group of eye diseases that lead to damage of the optic nerve, which transmits visual information from the eye to the brain. Glaucoma may cause vision loss if left untreated. It has been called the "silent thief of sight" because the loss of vision usually occurs slowly over a long period of time. [5]
Oscillopsia is a visual disturbance in which objects in the visual field appear to oscillate. The severity of the effect may range from a mild blurring to rapid and periodic jumping. [1] Oscillopsia is an incapacitating condition experienced by many patients with neurological disorders. [2] It may be the result of ocular instability occurring ...
It can result in chronic kidney failure, hypoalbuminemia, which can cause ascites and peripheral edema, and nephrotic syndrome, which can cause hypertension or hypercoagulability. Familial renal disease is an uncommon cause of kidney failure in young dogs. Most causes are breed-related (familial) and some are inherited.
Some people think that dogs howl at sirens because the sound hurts their ears, but Spruce Pets says probably not, "For some people, the high-pitched squealing of a siren can be an annoyance to our ...
