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.
If cat’s eyes do not pay attention to care, there will be a lot of eye diseases
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 prolapse occurs in one side of the eye, 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 fundus fat * * block shrink, 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
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 when they give their cats a medical examination for the first time.
Epiphora of cat
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.
It has always been said that the eyes are the window of the soul. The eyes are not only very important to human beings, but also important organs for cats. On the one hand, they reveal their beauty. On the other hand, they are also one of the organs for communication with human beings. We often find many interesting things in cat’s eyes, such as cat’s emotional changes. For cats, the eyes are an important organ. Eye abnormalities should be detected as soon as possible. There are many reasons that cause cat’s eyes to be watery and dropsy. On the one hand, it may be caused by improper feeding and inflamed, on the other hand, it may be the symptoms of eye diseases.
There are many symptoms of the disease. The hospital usually says that it is caused by bacteria and viruses. When the cat is about three months old, the earliest time is more than eight weeks, the vaccine should be started. The cat triple therapy is aimed at herpes, nasal branch, cat plague, etc. Of course, environmental hygiene and nutrition are also essential. Here are some symptoms and treatments.
1¡¢ Ophthalmia neonatorum
More tears, tear outlet abnormal or eyelid entropion, eyelashes stimulate the cornea, eyelid ectropion, etc., leading to tears, more eye droppings. Lacrimal disease usually occurs in the case of excessive tears and abnormal lacrimal glands. Persian cats with small nosed faces sometimes get the disease. The disease is closely related to the shape of the eyes and nose.
2¡¢ Conjunctivitis and keratitis, etc
The thin membrane above the white eye is called conjunctivitis. Conjunctivitis is a common disease. Cats living in newly decorated houses and families with poor indoor sanitation often have this disease.
Etiology: bacterial and viral infection, trauma, allergy, drug or plant irritation, garbage, dust, etc.
Symptoms: excrement, blinking, tears, blinking film exposure. Serious can also cause conjunctival swelling. There are symptoms of cat viral rhinotracheitis, cat cold pathogen infection and other diseases.
Cause: eyelashes, trauma, entropion or conjunctivitis can lead to corneal inflammation.
Symptoms: sore eyes, tears, cloudy and white cornea (but not the same as cataracts).
Medical manual: the general practice is to apply a warm towel on the cat’s eyelids to promote blood circulation, and then use some antibiotic ointment prescribed by a pet doctor for treatment.
From the name, we know that it must be related to tears. Some cats always have wet eyes, as if there are tears flowing out. Tears refer to the phenomenon that there are many tears, such as crying or inflammation of the eyes; and the phenomenon of tears overflow is an abnormal phenomenon of tears. 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, the owners of these cats should remember to wipe their eyes every day.
Cause: excessive secretion of tears or obstruction of lacrimal duct.
Symptoms: the hair under the cat’s eyes is tan.
Speaking of this disease, it is necessary to mention the elder cats, because cataracts generally appear in older cats. If a cat is older and has diabetes, it has a very high risk of developing cataracts. It is not a white haze in the eyes, or cataract. The spots on the lens surface of old cats are not necessarily cataracts, but may be caused by changes in the refractive index of the lens at the end of the year and do not affect vision.
Cause: the lens becomes white and opaque due to congenital or postnatal reasons.
Symptoms: the cat’s eyes become white and opaque.
Medical manual: 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.
Many people have heard of this disease, but cats are also troubled by it.
Cause: glaucoma is caused by an increase in anterior aqueous humor between the cornea and the lens, resulting in increased intraocular pressure. In addition, if the cat’s eyes bleeding, or because of various reasons caused by eye fluid circulation can not, can also cause glaucoma.
Symptoms: enlarged eyes, cloudy cornea, etc.
Entropion is not common. The causes of the disease are mostly seen in the lower eyelid structure of the outer corner of the eye. The reason of entropion stimulates the eyeball and the eyelid muscle spasm leads to more serious tears, corneal injury, eyelid entropion and so on. Operation is an effective method to correct entropion.
Cat eyelid eversion is due to cat bite, traffic accidents and other trauma caused. Some parents believe that cat eyelid ectropion is not a big problem, and these symptoms can be observed from the appearance of symptoms. When the pet cat has eyelid ectropion, it is recommended to take it to the pet hospital for inspection in time. With the help of the veterinarian, prescribe some eye medicine to wipe the cat.
Mild bacterial inflammation generally has eyes red and swollen, eye secretions mucilaginous, eyes are mucilaginous secretion closed, if a few days have not rubbed around the dirty cat’s eyes, let the secretions paste the eyes, to clean the eyes will have pus inside, these are OK, don’t worry, cat eye inflammation is very normal, very easy to self-treatment. First clean up secretions, and then take chloramphenicol eye drops, 3-5 times a day, one or two drops each time, adhere to two or three days will definitely improve.
2¡¢ Eye drops for treatment:
1. Anti infective eye drops:
¢Ù Anti bacterial eye drops: chloramphenicol eye drops, norfloxacin eye drops, Rifampicin Eye Drops and tailibito eye drops
Tobers eye drops sulfacetamide sodium eye drops
¢Ú Antiviral eye drops: ribavirin eye drops ribavirin eye drops
¢Û Antifungal eye drops: fluconazole eye drops and clotrimazole eye drops
The eyes are the windows of the soul, so are the human beings and cats. A pair of bright big eyes, the achievement of the cat’s unique agility and lightness. So that cats can see clearly and move freely in the dark. However, the cat’s eyes are also more susceptible to diseases, such as increased eye secretions, tears and so on. This will not only make the cat feel unwell, but may even mean that the cat has developed some terrible disease. If the cat’s eyes are abnormal, the cat parents must pay attention to it and take the cat to see a doctor as soon as possible.
1¡¢ Causes and symptoms of increased eye secretions and tears in cats.
Healthy cats don’t have too much secretions in their eyes. When a cat wakes up, there is occasionally a small amount of brown secretions around the corners of its eyes, just like humans. Cats “wash their faces” with their own paws every day, and the secretions are removed. Under normal circumstances, the cat’s eyes will be kept clean.
Polydacrysis is a condition in which tears are too much to spill over to the face. Tears mainly occur in the inner corner of the cat’s eyes. Sometimes the cat’s tears will make the hair around the corner of the eye turn reddish brown, which is mainly due to the discoloration caused by some components in the tears.
(1) The manifestations of excessive tear secretion were photophobia, frequent blinking, conjunctival flush swelling and tears;
(2) Lacrimal duct stenosis or blockage caused by: Tears increased significantly, each blink accompanied by tears outflow;
(3) Foreign body stimulation: cat eye pain or eyelid spasm;
(4) Severe viral conjunctivitis: often with eyelid and eyeball adhesion symptoms;
The causes of polydacryocystia are mostly caused by lacrimal duct stenosis or obstruction. Tears secreted by the lacrimal glands are distributed on the cornea through blinking and the third eyelid, to prevent corneal cells from drying and necrosis. The production of tears is also continuous, and tears will continue to enter the corner of the eye, through the nasolacrimal tube into the nasal cavity. If the nasolacrimal duct is blocked, the tear cannot enter the nasal cavity and will flow out from the inner corner of the eye.
For Persian cats and Garfield cats, they are more likely to suffer from polydacrysis. Because their facial structures are different from those of other cats, the lacrimal glands of Persian cats and Garfield cats are short, and they are prone to tear symptoms. For example, Persian cats shed tears when they see food or yawn. It’s not a genetic defect that causes it.
Conjunctivitis is one of the most common eye diseases in cats. Feline conjunctivitis is mainly caused by infectious respiratory diseases, such as feline herpes virus, mycoplasma, chlamydia, etc., as well as cat lacrimal duct occlusion and drug allergy. The main characteristics of its symptoms are conjunctival congestion, edema, increased secretion, generally divided into acute and chronic conjunctivitis.
(1) Acute conjunctivitis: Tears increase, at first for water, and then become gray white mucus or yellow green secretions, conjunctiva congestion, flushing, edema, photophobia, etc., serious can also lead to conjunctival necrosis, eye adhesion.
(2) Chronic conjunctivitis: cat eye corner has reddish brown tear marks, conjunctival congestion, conjunctival coarseness, sometimes visible mucinous secretion.
The cornea is transparent because there are no blood vessels in it, so it is transparent. Keratitis is also one of the most common diseases in cats. It is characterized by corneal lesions and conjunctivitis. Once there is inflammation in the cornea, the transparency will change, making the cornea look turbid.
Keratitis is caused by external factors, such as corneal trauma, foreign body stimulation, or eyelid defect, entropion, exophthalmos and other eye diseases. Deep corneal inflammation and ocular bacterial infection can also cause keratitis.
(1) Traumatic keratitis: there are trauma marks on the corneal surface, and the injured parts are rough and uneven. The symptoms of ulceration include photophobia, blurred vision, blepharospasm, pale yellow or yellow haze of cornea. In case of cat herpesvirus infection, the patient may have runny nose, hair and tears.
(2) Keratitis caused by internal inflammation: does not cause ulcers. Corneal opacity, iris and cornea adhesion, photophobia, pupil narrowing and so on.
4. Entropion / eversion
Eyelid entropion in cats means that the eyelids bend inward, causing irritation to the hair of the skin. Entropion is often caused by congenital or chronic conjunctivitis. But eyelid eversion is not common, facial trauma and chronic conjunctivitis, conjunctival ulcer can cause ectropion.
(1) Eyelid entropion will cause corneal irritation, tears, foreign body sensation, corneal erosion, spasmodic entropion symptoms will be more serious. Because the cat’s cornea is rubbed, if not treated in time, it may lead to blindness.
(2) Eyelid eversion has little effect on cornea, slight eversion can dry conjunctiva of eversion part, and serious eversion can lead to polydacrysis and corneal dryness.
5. Newborn felitis
Newborn cat’s ophthalmitis refers to the acute conjunctivitis of the kittens under 2 weeks old. Because the eyelids of the kitten can not be opened, the secretion remains in the conjunctival sac, causing swelling. There is purulent eye secretion flowing out of the inner corner of the eye, and even the whole eyelid is covered with secretion. The eyes of the sick cats are obviously enlarged compared with the normal cats in the same litter. If the cornea perforation is caused by keratitis, the kittens will be blind.
(1) Conjunctival congestion, edema, swelling of the third eyelid, erosion, eyes can not open, bleeding, hair loss, serious eyelid adhesion, corneal ulcer perforation, eye lens prolapse.
(2) If it is caused by the virus, eyelid swelling will be light, secretion is mucilaginous or watery.
(3) Chlamydia infection, eyelid swelling is the most obvious, secretion is mucilaginous or purulent, the color is reddish brown, light brown.
Blepharitis refers to the acute or chronic inflammation of eyelid skin, especially the eyelid margin. It can occur alone or accompanied by conjunctivitis and meibomian gland inflammation.
(1) Acute: palpebral margin and around eyelid congestion, swelling, yellow scab formation, peeling off the scab after exposing the eyelash root pustule. With the development of inflammation, the eyelid conjunctiva may have a small grain size of gray yellow pus spots, purulent secretion from the inner corner of the eye.
(2) Chronic: palpebral margin erosion or ulcer, eyelashes fall off, eyelid margin thickening, valgus or external rotation, eyelashes disorderly born, tears overflow.
(3) The symptoms of fungal or parasitic infection are hyperemia, swelling, depilation, allergic reaction or parasitic infection, which can also cause severe itching of eyelid, often leading to local scratch and abrasion of eyes.
Glaucoma, also known as green cataract, is an eye syndrome characterized by increased intraocular pressure and visual impairment due to the obstruction of posterior aqueous humor discharge. Often lead to vision loss or loss.
(1) At the beginning of the disease, tears, corneal edema and hyperemia of the outer sclera were observed.
(2) Acute cases may appear photophobia, tears, pain.
(3) High intraocular pressure can cause eyeball enlargement, angle edema, haze like turbidity, pupil dilation, and eventually lead to visual loss or deterioration.
2¡¢ How should cat shed tears and eye secretion increase?
Don’t worry if your cat has symptoms of tears or increased eye secretions. You can measure the cat’s temperature to see if it has a fever. If the cat’s nose is dry under normal conditions, it may be caused by fever. At this time, it is necessary to take a temperature for the cat. The normal temperature of the cat is 38 £þ C, which belongs to mild heat, and above which is high fever. If the cat’s temperature is too high, or below 38 degrees, you need to go to the pet hospital for treatment. In the hot summer, if the indoor temperature is too high, the cat’s temperature may be higher than usual, but generally not more than 1 degree.
If the cat’s temperature is too high, or eye secretions are more, mucinous or purulent secretions, we must go to the pet hospital for treatment in time, so as not to delay the disease.
If for various reasons, can not go to the pet hospital treatment. When the cat’s temperature is normal, diet and mental status are normal, and eye secretions are not purulent or less, aureomycin eye ointment, chloramphenicol eye drops or pet eye drops can be used for preliminary care.
3¡¢ Eye care
1. Wash hands with soap before touching cats. Dip in some normal saline with tampon, gently wipe the cat’s eyes from the head to the end of the eyes, and then clean up the secretions. If there are dry secretions, you can first use normal saline to wet, after a while to dry the secretion softened after wiping. Do not use brute force to wipe or tear off the dry secretions, as it is easy to cause skin damage and inflammation around the cat’s eyes.
2. If there is secretions in the cat’s eyes, a few drops of artificial tears can be used to wash the eyes.
3. After cleaning the cat’s eyes, apply eye drops or chlortetracycline eye ointment to the corner of the cat’s eyes. Hold the cat’s head in your hand to keep the eye drops from flowing out quickly.
4. To prevent the cat from scratching the eyes, the cat should wear Elizabeth collar. Remove the collar when feeding, and be careful not to let the cat scratch the eyes at this time.
5. For cats, such as Garfield and Persian cats, who are not caused by diseases but are born with lacrimal duct defects, do not use drugs. They only need to wipe and clean the tear marks and secretions on the eyes of cats. If more serious, can go to the pet hospital under the guidance of the doctor medication.
4¡¢ How to prevent it.
1. Pay attention to the health of the cat’s living environment and keep the eating utensils clean.
2. Often let the cat can bask in the sun, the sun ultraviolet rays have bactericidal effect.
3. Vaccinate cats regularly.
4. Do not easily give the cat self medication, to prevent cat allergic reaction.
5. If there are more than one cat at home, pay attention to isolate the sick cat for treatment.
6. Scientific feeding and reasonable diet. Do not give cats raw meat, salty and spicy food.
