Characteristics of cataract: dog eyes are turbid, please see the picture above!
The dog's vision becomes amblyopic, and the owner can't respond to its call, which will make it look confused!
Cataract is not a patent for old dogs, or even the opposite. Some dog cataracts belong to hereditary juvenile cataracts. Because of genetic defects, they often occur at a young age or before the age of 6. There are dozens of dog breeds of hereditary cataract, such as poodle, Maltese, Beardog, Shiba Inu, Schnauzer and so on. On the contrary, the incidence of cataract in middle-aged and elderly dogs is very low, and only 1 ~ 20% of elderly dogs will have cataracts, and most of them are secondary cataracts, such as retinal degeneration and diabetes.
After a dog gets a cataract, the lens behind the pupil becomes turbid, which will not only affect his vision, but the most terrible thing is that once the cataract matures, the protein of the cataract will dissolve and liquefy and leak out of the lens capsule, and there is more than 90% chance of inflammation and complicated with lens uveitis.
Among all kinds of cataracts, dogs are the most likely to induce inflammatory complications. Serious complications or old cataracts may lead to intraocular hemorrhage, high intraocular pressure glaucoma and lens displacement, which may lead to serious eye diseases or intractable diseases. It is often necessary to remove stubborn diseases by removing eyes or giving up eyeballs. At present, eye specialist hospitals can use artificial artificial eyes instead of enucleation to maintain the appearance of the eyeball, but only if the eyeball shell is healthy and there is no corneal perforation. The expert's operation cost is about 65438 yuan+0,000 ~ 6,000 yuan.
Cataract can be divided into four different stages: initial stage-immature stage-mature stage-over-mature stage, and immature stage can be divided into early immature stage (; 50%), the mature is 100% lens opacity. Mild and moderate endophthalmitis is not easy to find in appearance, but when the owner notices that the dog has eye discomfort symptoms such as squinting and blinking, it shows that the cataract is mature and has obvious inflammatory complications.
If the dog goes to see a doctor because of cataract, it is necessary to confirm which stage the dog's cataract belongs to. Early or early cataract does not require surgery, and health care methods (eye drops or oral eye care nutrition) can be used to delay the deterioration; However, it is recommended to undergo cataract extraction surgery from the late immature stage to the mature stage/over-mature stage. If you don't have surgery, you should at least actively control the accumulation of intraocular complications and inflammation, track the deterioration of inflammation, and monitor whether intraocular pressure and lens position are displaced.
But if the cataract is not removed, it means that the root of inflammatory complications still exists, and inflammation may accumulate in the future, leading to more complications. Light spot medicine only treats the symptoms, not the root cause, which may slow down the degree of inflammation, but it cannot cure the root cause of intraocular complications "cataract". As far as Taiwan Province Province is concerned, most cataracts are hereditary, so dogs with high incidence should pay special attention. As we all know, many cataracts caused by excessive sunlight exposure may be secondary degenerative cataracts caused by retinal degeneration in middle-aged and elderly dogs, which causes dogs to have their sick eyes removed, as shown above.
