How Do Vets Diagnose Dog Eye Allergies
Although a test called conjunctival cytology may reveal inflammatory cells that will confirm a diagnosis of allergic conjunctivitis, the cells are not always present. As a result, many veterinarians will diagnose eye allergies through the process of elimination.
Your veterinarian may perform several brief tests to rule out diseases with similar symptoms, like eye infections, dry eye, or corneal ulcers. Other details, like your dogs age, breed, and history of itchy skin, can also help point your veterinarian to this diagnosis.
In rare cases, a biopsy of the conjunctival tissue around the eyestaken while your dog is under general anesthesiamay be needed to achieve a definitive diagnosis, or to rule out other, more serious causes of red eyes.
An emerging test called the conjunctival provocation test has shown promise as a quick and easy test to definitively diagnose allergic conjunctivitis. However, its currently not widely available and would likely be performed by veterinary dermatologistsnot your general practice veterinarian.
When Do I Need To See My Doctor About Red Eyes
There are certain times you may need to see your doctor or ophthalmologist, which is an eye specialist doctor.
You need to see your doctor if your red eyes are accompanied by severe eye pain, vision changes such as halos or blurred vision, headaches, nausea, vomiting, eye discharge, swelling, light sensitivity, or if there is an object in your eye you can not get out. If you are unable to keep your eye open you need to also seek medical attention.
See your doctor if over-the-counter treatments are not working or if your symptoms persist or are getting worse as most cases clear up on their own.

What Are Red Eyelids
Red eyelids can result from any condition that irritates, inflames or infects the eyelid. Allergies, infections, and even crying can cause your eyelids to redden. Red eyelids may also result from trauma to the eye area. Red eyelids are commonly associated with other symptoms like itching, swelling, irritation, bumps, increased tearing, or discharge.
Allergies are a very common cause of red eyelids. An allergy that affects your eyelid may be local, such as an allergic reaction to eye makeup, or more generalized, such as hay fever. Allergies that involve the membrane lining the inside of your eyelids and covering the whites of the eyes are called allergic conjunctivitis.
Infections or inflammations of the eyelid margin, the area near your eyelashes, are also frequent causes of red eyelids. These conditions include blepharitis , chalazion , and stye or hordeolum .
Most conditions that affect the eyelids do not threaten your life or vision, and red eyelids usually get better on their own within a few days. In rare cases, red eyelids can be associated with anaphylaxis, a life-threatening allergic reaction, or orbital cellulitis, a serious infection of the skin around the eyes. Because your eyes and vision are vital to your quality of life, be sure to contact your health care provider if you have any eye symptoms that cause you concern.
Seek prompt medical care if your red eyelids are persistent, recurrent, or cause you concern.
Is It Pink Eye Or Allergies
It can be difficult to tell the difference between allergic conjunctivitis and pink eye, a conjunctivitis caused by a virus or bacteria. Eye allergy tends to clear secretions and itching, while bacterial infections causing pink eye usually involve yellow or greenish discharge. Most conjunctivitis is viral rather bacterial and resolves well after applying warm compresses. If only one eye is affected, take care to not touch or apply anything to the unaffected eye after touching the eye with the issue.
Never put corticosteroid drops into your eyes without having a comprehensive eye exam. It is very difficult to tell the difference between conjunctivitis caused by allergy or conjunctivitis caused by bacteria corticosteroids can be dangerous with certain bacterial diseases. Eye allergy tends to cause clear secretions and itching, while bacterial infections usually involve yellow or greenish secretions.
If you suspect that you have eye allergies visit a healthcare professional. Preventing and treating eye symptoms may be part of your overall treatment plan.

Eye Symptoms And Anaphylaxis
An allergic reaction to a food, insect sting or bite, or medication may cause eye symptoms with swelling, itching and redness of the conjunctiva and soft tissues around the eyes. Individuals who are at risk of anaphylaxis should be referred to a clinical immunology/allergy specialist.
Eating of foods containing monosodium glutamate or the preservative sodium metabisulfite will occasionallycause swelling and redness of the eye. However this is not a true allergic reaction and therefore symptoms will be less severe.

Severe cases may require the use of oral medications in addition to eyedrops.
