What is a cataract?
Cataracts are opacities of the eye's lens or its
capsule. They are to be differentiated from nuclear
sclerosis. (This condition, which appears
as a slight graying of the lens, usually occurs in both eyes
at the same time and shows up in geriatric dogs, cats, and
equine. With nuclear sclerosis, the loss of transparency occurs due
to compression of the linear fibers in the nucleus of the eye's lens.)
Cataracts are usually classified by their
age of onset (congenital, juvenile, senile), anatomical location,
cause, and degree of opacification. (Incipient
cataracts are very small, less than 15 percent of the
lens. Immature cataracts are greater than 15 percent of
the lens, however, a tapetal reflection is still visible. In mature
cataracts there is solid opacity of the entire lens and no tapetal
reflection. With hypermature cataracts the lens wrinkles and liquefies).
Cataracts can affect all breeds and ages
of dogs, cats, and equine.
Dogs, cats, and equine with cataracts should always be referred
to a qualified veterinary ophthalmologist for evaluation.
How do cataracts form?
The basic mechanism of cataract formation is thought
to be cross-linking of lens proteins, which produces the following
The specific causes of cataract formation are numerous and include genetic defects, nutritional deficiency, focal disruption of normal lens metabolism by adhesion to uveal tissue (synechia), radiation, high blood glucose, hypocalcemia, toxins, faulty embryogenesis, and altered composition of the aqueous humor caused by uveitis.
Cataracts are a common complication of diabetes mellitus in dogs. In fact, 75 percent of dogs develop cataracts and blindness in both eyes within one year of being diagnosed with diabetes.
Cats are frequently brought to the veterinarian for evaluation of painful, red eyes due to glaucoma (excess pressure in the eye), uveitis (inflammation in the eye) or lens dislocation, all of which commonly result in cataracts.
Horses may be born with cataracts, or the condition may develop soon after birth. Adult horses typically develop cataracts as a result of uncontrolled uveitis (ERU – Equine Recurrent Uveitis).
How do I know if my dog, cat or equine has cataracts?
If you or your veterinarian notice decreased vision or clouding of the eye, your animal should be examined by a veterinary ophthalmologist and given a comprehensive eye examination.
It is best to have your animal's eyes examined
before a cataract causes complete blindness, such early action
will allow for examination of the intraocular structure (especially
As the formation of a cataract will stimulate inflammation (called uveitis) within the eye, your animal may experience ocular pain and redness. This situation should be brought to your veterinarian's attention immediately.
Our recommendation: Dogs, cats, and equine with cataracts should always be referred to a qualified veterinary ophthalmologist for evaluation.
ADER Enterprises has developed three ophthalmic
nutraceutical eye drop formulas to improve and maintain clear vision
in dogs, cats, and equine:
sold only through licensed veterinarians. For Sales contact us at email@example.com
EquiVision® is sold only through
licensed veterinarians. For sales contact us at firstname.lastname@example.org
Our recommendation: Do not use any ophthalmic steroid
or steroid derivative in combination with PetVision®,
PetVisionPro® or EquiVision®. Steroids
cancel the positive effects of our products, although they
carry no risk for your dog, cat, or equine. If you have any
questions about the use of our products, please contact us
How do PetVision®,
PetVisionPro® and EquiVision®,
help dissolve incipient cataracts ?
The basic abnormality in incipient cataract formation is the degeneration of the normal protein structure of the lens fibers.
The cross-linked eye lens proteins occur in vivo and may contribute to cataractogenesis.
Anti-glycation compounds such as our ophthalmic
nutraceutical eye drops reverse incipient cataracts, producing the
following biochemical reaction:
Our research and analysis support the following hypothesis: The ophthalmic nutraceutical eye drops disaggregate glycated proteins, thus reducing any opacification (incipient cataract) on the eye lens of dogs, cats, and equine.
