DogCondition: My dog's eyes have become very red since a while ago, and sometimes some discharge Watery or mucoid discharge. Some dogs have no discomfort in their eyes, but some dogs become very uncomfortable with their eyes, and they cannot open their eyes very much. They want to scratch their eyes with their forelimbs or rub their heads against furniture or family members. Ask their eyes What happened? How to deal with it?

Red eyes are a common eye symptom in dogs, which often makes dog owners very worried. Treatment considerations are not the same, but most of these problems are caused by inflammation or abnormality in a specific part of the eye. If you don’t treat it or use drugs indiscriminately, not only will you not be able to recover, but some more severe cases will continue to deteriorate, causing serious consequences, such as , a decrease or loss of vision. Symptoms of not opening the eyes, usually due to eye pain or discomfort caused by blepharospasm. Scratching the eyes with the forelimbs or rubbing the furniture or family members with the head is a natural reaction behavior caused by itchy or uncomfortable eyes. The following introduces the common causes and treatment principles of red eyes.

There are many reasons for eye redness, which can be generally divided into two categories: lesions on or near the eyeball surface and lesions within the eyeball. In the latter, lesions in the eyeball need to be diagnosed and treated as soon as possible to avoid serious sequelae due to late detection. Two common causes of pink eye are described below.

A. Lesions on or near the surface of the eyeball:

Common conditions include, dry eye (in dogs), conjunctivitis (in large and infrequent cases) Proportion of dogs), conjunctival hemorrhage, corneal ulcer or trauma, third eyelid prolapse, etc.

1. Dry eye syndrome: the number one cause of red eye symptoms in dogs, and the cause that is often overlooked. Dry eye syndrome may be caused by a lack of tear film volume or a defect in tear film quality, causing The tear film cannot absorb, protect and nourish the surface of the eyeball (cornea and conjunctiva) normally, resulting in keratopathy and conjunctival hyperemia and redness. It is necessary to treat the underlying cause for effective and long-term improvement, rather than taking it lightly. Eye drops to temporarily prevent red eyes from affected dogs.

2. Conjunctivitis: It will cause extensive redness and redness of the eye conjunctiva, mostly non-infectious conjunctivitis in dogs, and infectious conjunctivitis in dogs. Canine conjunctivitis, in addition to allergic conjunctivitis, general conjunctivitis is often accompanied by eye secretions.

3. Conjunctival hemorrhage: often caused by trauma or impact on the head or eyes, showing bright red conjunctival congestion or bleeding redness.

4. Corneal ulcers and wounds: When the cornea is chronically irritated, ulcerated or wounded, blood vessels often proliferate on the surface of the cornea or near the wound, and it will also cause extensive conjunctival hyperemia and redness. It is thought that the reddening of the whites of the eyes is only a problem of the whites of the eyes, and ignoring the cornea (the black part of the eyeball) lesions is often the cause of the reddening of the whites of the eyes. In addition, corneal ulcers and wounds are much more painful than conjunctivitis and dry eye.

5. Prolapse of the third eyelid: There is a third eyelid in the inner corner of the dog's eye, which is sometimes red, swollen and congested due to prolapse.

B. Intraocular lesions:

Common intraocular lesions cause red eye symptoms including glaucoma and intraocular inflammation. These two conditions are more serious and more complicated than lesions on or near the eyeball surface. If not treated early or effectively controlled, it will cause blindness or even stubborn pain in sick animals.

1. Glaucoma: Severe redness of the sclera in the white of the eye, corneal edema, increased intraocular pressure and pupil dilation. Sometimes there are intraocular hemorrhage, eye pain in sick animals, swelling of the eyeball, rapid and irreversible damage to the optic nerve and retina, which can easily lead to blindness and stubborn pain.

2. Inflammation in the eye: Severe redness of the sclera in the white of the eye, and corneal edema, opacity of the anterior chamber, intraocular hemorrhage or suppuration, which can easily lead to blindness and secondary glaucoma, and cause stubborn glaucoma. sickness.

For the above-mentioned causes of pink eye, whether it is the lesions on the surface of the eye, the lesions near the eye, or the lesions inside the eye, the sick dog must be sent to the hospital. Ophthalmologists use several different ophthalmic instruments to conduct detailed professional examinations on the surface of the eyeball and the inside of the eyes of the affected dog to determine the degree, scope and cause of the disease, and then give appropriate treatment according to the diagnosis of the ophthalmological examination.

There are many causes of red eye symptoms in dogs, and some lesions deteriorate rapidly. Only through professional and detailed eye examinations will the eye lesions that should be really paid attention and attention will not be ignored. The most important thing is to find the root cause of the red eye symptoms. Only by treating the root cause can effective, long-term and real improvement be achieved. Instead of rashly giving the dog eye drops that temporarily make the eyes less red to suppress the symptoms, it will be affected by the temporary condition. Cover up and miss the best time for correct and active treatment, the condition will only get worse and worse. Some eye drops commonly used by people can make the eyes less red temporarily, but some of these ingredients will cause the side effects of decreased lacrimal gland function or more serious corneal lesions in dogs after a period of use. Before taking medicine after examination, the health of the dog can be guaranteed.
