An increased fluid pressure within the eye leading to pain and potentially loss of vision.
Glaucoma Symptoms
Glaucoma Causes
Dogs of some breeds are often born with abnormal filters and are therefore prone to getting inherited (genetic or primary) glaucoma in both eyes. Other breeds have a genetic predisposition to developing displaced (luxated) lenses, which block the filters, obstructing the flow of fluid. In both dogs and cats, the filters can be clogged with inflammatory cells if inflammation inside the eye (uveitis) occurs. Intraocular tumors can also lead to glaucoma.
Glaucoma Treatment
In early cases of glaucoma medical therapy is often instituted. The various medications work, primarily, in two different ways - to decrease production of aqueous humor and to open up the filter to make it more efficient. A pet may be prescribed a variety of topical and oral medications which work in concert to decrease intraocular pressure.
Some cases of glaucoma are resistant to the effects of medications. Surgical treatment of glaucoma may include laser therapy or cryosurgery to reduce aqueous humor production. When vision and comfort are no longer able to be maintained , additional surgical procedures may be recommended including either removal of the entire eye (enucleation) or removal of the ocular contents (evisceration) and placement of a prosthesis (false eye).
