Dog’s condition: Since a while ago, my dog’s eyes have become red in the whites of the eyes, and sometimes there are some watery or mucus-like secretions. 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’s wrong? How can I deal with it?
Physician:
Red eyes are a common eye symptom in dogs and are often very worrying for dog owners, The causes and treatment considerations for red eyes in dogs are not the same, but most of these problems are caused by inflammation or abnormality in a specific part of the eye. Continue to worsen, with serious consequences, such as vision loss or loss. 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 caused by itchy or uncomfortable eyes. The following introduces the common causes and treatment principles of red eyes.
Causes
There are many causes of eye redness, which can generally be divided into ” lesions on or near the eyeball surface” and ” Diseases within the eyeball,” two major categories of causes, and 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 the quality of the tear film. 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 temporarily prevent red eyes in 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: usually caused by trauma or impact on the head or eyes, showing bright red conjunctival congestion or hemorrhage 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 canthus of the dog, 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 complicated than lesions on or near the eyeball surface. If not treated early or effectively controlled, it will cause blindness or 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, and 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, corneal edema, the opacity of the anterior chamber, intraocular hemorrhage or suppuration, which can easily lead to blindness and secondary glaucoma, and cause stubborn glaucoma. sickness.
??Principles of Diagnosis and Treatment??
For the above-mentioned causes of pink eye, whether it is the lesions on the surface of the eyeball, nearby lesions, or lesions inside the eyeball, The sick dog must be sent to the hospital. An experienced ophthalmologist uses several different ophthalmic instruments to conduct a detailed professional examination on the surface of the eyeball and the inside of the eye of the sick dog to determine the degree, scope, and cause of the disease. Check the diagnosis and give appropriate treatment.
There are many reasons for red eye symptoms in dogs, and some lesions deteriorate rapidly. Only through professional and detailed eye examinations will the eye lesions that should be paid attention to 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 people’s commonly used eye drops can temporarily make the eyes less red, but after a period of use, some of these ingredients will cause the side effects of decreased lacrimal gland function or more serious corneal lesions in dogs. Before taking medicine after examination, the health of the dog can be guaranteed.
