Corneal ulcers are one of the most common eye diseases in dogs. They are caused by trauma, detergent burns, and infections. Other eye conditions can cause corneal ulcers, such as entropion , distichiae , corneal dystrophy , and keratoconjunctivitis sicca (dry eye).
A Gundersen flap, also known as Gundersen's flap, Gundersen's conjunctival flap, or conjunctivoplasty, and often misspelled Gunderson, is a surgical procedure for correcting corneal disease. It involves excising a damaged section of cornea, and replacing it with a section (or "flap") of the patient's own conjunctiva. [1]
Corneal ulcer, or ulcerative keratitis, is an inflammatory condition of the cornea involving loss of its outer layer. They are caused by trauma, detergent burns, and infections. Other eye conditions can cause corneal ulcers, such as entropion, distichia, corneal dystrophy, and keratoconjunctivitis sicca. [63]
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 ...
Peripheral Ulcerative Keratitis (PUK) is a group of destructive inflammatory diseases involving the peripheral cornea in human eyes. [1] The symptoms of PUK include pain, redness of the eyeball, photophobia, and decreased vision accompanied by distinctive signs of crescent-shaped damage of the cornea.
It is a dry looking corneal ulcer with satellite lesions in the surrounding cornea. Usually associated with fungal ulcer is hypopyon , which is mostly white fluffy in appearance. Rarely, it may extend to the posterior segment to cause endophthalmitis in later stages, leading to the destruction of the eye.
It is seen in brachycephalic (short-nosed) dog breeds because of the shallow orbit. It can lead to keratitis secondary to exposure of the cornea. Exophthalmos is commonly seen in the pug, Boston terrier, Pekingese, and shih tzu. It is a common result of head trauma and pressure exerted on the front of the neck too hard in dogs. In cats, eye ...
Recurrent corneal erosion (RCE) is a disorder of the eyes characterized by the failure of the cornea's outermost layer of epithelial cells to attach to the underlying basement membrane (Bowman's layer). The condition is excruciatingly painful because the loss of these cells results in the exposure of sensitive corneal nerves.
