The bright eyes of cats are the treasures of cats. Many people become a group of other cat lovers because of their fascination with cat eyes. The special structure of cat’s eye enables it to see things in the dark, and a cat can also be said to be an animal moving by vision. But the cat’s eyes are very delicate organs, it is also very fragile, will become dim due to external infection, so in peacetime, if there are any mild symptoms, we should send the cat to a doctor as soon as possible, so as not to cause irreparable damage.
1¡¢ Retinal detachment
Retinal detachment is caused by contusion, infectious diseases, genetic or dietary imbalance, resulting in retinal photosensitivity, cell degeneration, inflammation and rupture of the reticulum. Retinal detachment will gradually aggravate, and if not treated, it will lead to blindness. If the cat is found to have this eye disease, the owner must take the cat to a doctor as soon as possible to prevent the disease from deteriorating.
Conjunctiva is located in the inner layer of the cat’s eyelids, covering the visible surface of the eyeball and the white eye. Conjunctivitis presents different symptoms according to the degree of conjunctivitis, including tears, redness and swelling, eyelid closure, and sticky yellow secretions in the eyes. The general symptoms may occur in one or both eyes. Conjunctivitis is often caused by the stimulation of soap, steam, smoke, respiratory tract infection, congenital eyelid curl, contusion or bacterial infection. If the secretion is sticky and yellow, you should go to the veterinarian for diagnosis and treatment. If the disease leading to conjunctivitis is more serious, it should be treated first. Remove the dirt around the eyes, prescribe eye drops from the hospital, and spot the cat’s eyes according to the doctor’s instructions. Use Eliza white-collar to prevent eye scratching.
3¡¢ Problems with the third eyelid
The cat’s third eyelid, also known as the blinking membrane, covers the conjunctiva to protect the cornea and remove foreign bodies, and to prevent excessive dryness of the eyes. If the third eyelid of unilateral eye is prolapsed, it may be caused by eye irritation. But the cause of this disease has not been fully understood, but it is very likely that the virus caused functional decline, so that the eyeball muscle retracted into the eye socket, or the orbital fat tissue block shrinks, causing the eyeball to move backward and the third eyelid to squeeze forward. In addition, gastrointestinal discomfort, chronic parasitic diseases, anorexia, fever, poisoning or multiganglion atrophy may be the causes. Therefore, if the cat has symptoms of prolapse of the third eyelid and does not disappear, please take them to the veterinary hospital and ask the veterinarian to find out the real cause.
4¡¢ Entropion and ectropion
Eyelid to the eye direction is known as entropion, most of which are caused by congenital, but occasionally because of cat fighting, and accidentally caused by eyelid damage. Eyelid entropion when the skin will stimulate the eyes, corneal injury, tears, and cause keratitis, corneal ulcer and so on. As for eyelid ectropion, it is due to cat bites, traffic accidents and other trauma caused. The treatment of entropion and ectropion should be performed as soon as possible before the cornea is damaged or the damage is not serious, so as to avoid permanent injury to the cat’s eyes.
Epiphoria is caused by excessive secretion of tears or obstruction of lacrimal ducts. The hair under the cat’s eyes will be dyed brown with this disease. It may be related to eye allergy, eye infection, conjunctivitis, keratitis and respiratory tract infection. This disease is common in Persian cats with short heredity. This eye disease may be related to eye allergies or respiratory tract infections, and often occurs in cats with short genetic faces, such as Persia and heterosexual. Therefore, owners of these cats should carefully check their eyes during their first medical examination.
Glaucoma is caused by an increase in the anterior aqueous humor between the cornea and the lens, resulting in increased intraocular pressure and corneal opacity. In addition, if the cat’s eyes bleeding, iris and related tissue inflammation or tumor caused by eye fluid circulation can not be caused. Patients with glaucoma, serious can cause blindness. Therefore, if the cat’s eyes appear swelling, corneal contact or any change, you should seek medical advice as soon as possible. Glaucoma has medical treatment methods, such as eye medicine, but this depends on the severity of glaucoma, if in addition to high intraocular pressure, eye infection or even pus, then surgery is a faster solution.
Under normal circumstances, the cornea is transparent, but it will become turbid or light blue when damaged and inflamed by eyelashes, trauma, entropion or conjunctivitis. It turns white and opaque, but it’s different from cataracts. If the cornea is not infected, the disease will be cured quickly, but if it is infected, ulcers and inflammation will follow. The symptoms of keratitis are eye pain, tears and corneal opacification. If the above symptoms are found in cats, they should go to the veterinary hospital for examination. Never use eye drops for human use or eye drops containing paraadrenocorticotropin. The general practice is to use a warm towel on the cat’s eyelids, which can promote blood circulation, and then use some antibiotic ointment prescribed by a pet doctor for treatment.
Opacification of the pupil of cat’s eye is often due to the lens due to congenital or natural reasons and become turbid, opaque, known as cataract, generally appears in older or diabetic cats. The opacities on the lens surface of old cats are not necessarily cataracts, which may be caused by the change of refractive index of lens in old cats and will not affect vision. However, if you find that the cat’s eyes become white and cloudy, you should seek medical advice as soon as possible. The condition of cat cataract should be evaluated by veterinarian. If both eyes have cataracts, surgical treatment is the only recommendation. The common treatment for cataracts is surgery to remove the opaque parts and restore the cat’s vision. Only experienced doctors can do this kind of operation. If the operation can’t be done or the operation fails, the cat’s vision will gradually lose.
Of course, it is not a white haze in the eyes, or a cataract. The spots on the lens surface of an old cat are not necessarily cataracts, but may be caused by changes in the refractive index of the lens when they are old, and do not affect vision.
Cat’s eye disease can be transmitted, so it should be isolated. If it is viral, it is easy to infect. Pay attention to the disinfection of foreign articles. If it is Persia and other daily eye care, or relatively light inflammation, then use anti-inflammatory eye drops and eye wash can be combined.
