The difference between cat glaucoma and cataract is that glaucoma manifests as blepharospasm, epiphora, howling, lethargy, anorexia, etc.; while cat cataract manifests as white pupils that grow and shrink with the intensity of light. .

Causes of cat glaucoma

The eyeball is filled with liquid aqueous humor, which can maintain the normal shape of the eyeball, and this aqueous humor will continue to circulate and replace the old with the new. Once the aqueous humor cannot be drained smoothly from the eye, it will This can cause an increase in intraocular pressure, which is called glaucoma, and the defect in the drainage path may be located in the pupil or iridocorneal angle. Glaucoma may be primary or secondary to other eye diseases; anterior chamber angle dysplasia is the most common cause of primary glaucoma. This is due to the appearance of a congenitally abnormal thin tissue at the ctenoid ligament. The entrance to the ciliary body fissure becomes narrow.

Feline glaucoma symptoms

Normal intraocular pressure is 15~25mmHg. Acute attacks of glaucoma are prone to eye pain, such as blepharospasm and epiphora. The pain may be severe enough to cause howling, drowsiness and anorexia, and may even occur within 24~ Irreversible blindness develops after 48 hours; other common symptoms include corneal edema, superficial scleral hemorrhage, etc. In addition, the pain symptoms caused by chronic glaucoma are less obvious and may show some or all of the symptoms that occur in acute cases. Although the degree is mild, it must not be ignored.

Feline glaucoma treatment options

Doctors will choose treatment methods based on the urgency of glaucoma. The goals are to control intraocular pressure and avoid permanent blindness, including intravenous injection of osmotic diuretics, intraocular pressure-lowering eye drops and surgery. .

When certain blind, painful, glaucomatous eyes cannot be successfully treated by all the above-mentioned treatments, the best way is to perform eyeball removal surgery and insert a silicone ball as a prosthetic eye. .

Cataract symptoms in cats

The lens is a transparent tissue derived from epithelium and contains many transparent fibers. Therefore, the definition of cataract is: regardless of its cause, any non-physiological opacification of the lens fibers and/or lens capsule. When you see that your cat's pupils no longer appear deep black, there is a possibility of cataracts. You can see that the pupils appear white and will increase and decrease with the intensity of light.

Cataracts in cats

Cataracts can be caused by many factors, some of which are congenital malformations, heredity, toxins, and radiation., trauma, other eye diseases, systemic diseases and aging, etc.

Cataract treatment options for cats

There are currently so-called cataract eye drops on the market, which can at best slow down the progression of cataracts. Surgery (lens removal) is the only treatment that can restore a cat’s vision, but the cat must be considered. Health and behavioral conditions, and cataract surgery is best left to a veterinarian with special research and practical experience in ophthalmology.
