Overview

The conjunctiva is a membrane that covers your eyeball and the inside of your eyelids. Conjunctivitis or "pink eye" occurs when something irritates this membrane. Irritation may cause your eyes to become red, inflamed, swollen, watery and itchy. The cause of the conjunctivitis may be infectious, but this article focuses on allergic conjunctivitis. Although allergic conjunctivitis is uncomfortable it does not hurt your eyesight and is not contagious.

An allergic reaction occurs when your body's immune system reacts to a foreign substance - an allergen - such as pollen or dust. In response to the allergen, your body releases a chemical called histamine that causes symptoms such as a runny nose, itchy eyes and sneezing.

Causes, Symptoms and Diagnosis

Some common allergens that can cause conjunctivitis include:

  • Pollen from trees, grass and ragweed
  • Animal skin and secretions such as saliva and pet dander
  • Perfumes and cosmetics
  • Skin medicines
  • Air pollution
  • Dust and mold
  • Smoke

Symptoms may include some, or all, of the following:

  • Itching - this symptom is most commonly associated with allergic conjunctivitis
  • Watering
  • Redness
  • Pain/discomfort
  • Feeling that something is in the eye
  • Discharge

We will evaluate your eyes to verify that your symptoms are caused by allergies and not by a viral or bacterial infection. Knowing the cause of the irritation will enable us to treat your eyes effectively.

Prevention

  • Try to identify and avoid the allergens that cause your symptoms.
  • Stay indoors when pollen and mold levels are high if you are allergic to pollen or mold. You can usually find out when allergen levels are high from weather reports.
  • Keep your doors and windows closed, and use an air conditioner during the summer months.
  • If your symptoms started right after you began using a new product, like a new moisturizer, detergent, or contact lens cleaning solution stop using it for a few days to see if your symptoms go away. 

If you cannot easily identify an allergy, talk to us. We may recommend allergy testing to pinpoint exactly what is causing your symptoms.

Treatments

A number of treatment options are available to relieve the symptoms and suppress the allergic response.

Relieving the symptoms:
  • Apply cold compresses using a cold washcloth.
  • Use preservative-free artificial tears. These are best used cold straight out of the refrigerator. You can use them several times a day to reduce the irritation.
  • Minimize exposure to potential allergens.
  • Do not rub your eyes. Rubbing your eyes causes more inflammation and will make your symptoms worse.
  • Don't wear contact lenses while you have allergic conjunctivitis because they will probably exacerbate your symptoms and you might get an eye infection. Wear your glasses until your eyes feel better.
Eye drops

We may recommend that you use antihistamine eye drops to suppress the allergic response. These drops can help relieve itchy, watery eyes and may keep symptoms from returning. Most eye drops are available over the counter.

  • Ketotifen fumarate drops seem to be the most effective for symptom relief. You can use them 2-3 times a day and continue for a long period of time if needed.
  • Drops such as naphazoline and pheniramine are less effective, but can reduce redness if used for short periods. You should not use these drops for more than 5 days at a time. If you use them regularly for long periods, they stop working and can actually make your eyes feel worse.
  • We may need to prescribe other eye drops if your symptoms persist.

Lifestyle Changes and Management

Home treatment
  • Don't touch or rub the eye.
  • Use lubricating eye drops or artificial tears to make your eyes feel better.
  • Use artificial tears up to 4-6 times a day.
  • Try chilling the artificial tears in the refrigerator for an additional soothing effect.
  • Wash your hands before using drops.
  • Place a cold washcloth over your eyes to reduce the irritation.
Contact lenses
  • Don't wear contact lenses while you have allergic conjunctivitis because they will probably make your symptoms worse and you might get an eye infection.
  • Wear your glasses until your eyes feel better.
Allergy medications available without a prescription
  • Antihistamines such as chlorpheniramine and non-drowsy loratadine provide relief from sneezing, runny nose and itching.
  • Decongestants like pseudoephedrine or phenylephrine provide relief from stuffy nose and ears.
  • Saline nasal sprays help to remove crusts, dry mucous and inhaled particles from your nose.
  • Sinus rinse kits can be helpful for thick nasal mucus accumulation.
  • If your allergies are not controlled with over the counter medications, ask us about a prescription for an anti-inflammatory nasal spray.
Prescription nasal sprays
  • Prescription anti-inflammatory nasal sprays such as flunisolide or fluticasone are the most effective group of medications for chronic treatment of allergy symptoms.
  • These medications can decrease the inflammation of the lining in your nose and relieve sneezing, itchy nose and congestion.
  • Other advantages are that they provide non-drowsy relief and have minimal side effects.
  • Nasal sprays do not work immediately and may take a few days to make a noticeable difference. 
How to use prescription nasal sprays:
  • Tilt your head forward and point the spray away from the septum (the wall between the nostrils) to minimize side effects when using nasal sprays.
  • Use your right hand when spraying the left nostril and your left hand for the right nostril.
  • Alternate sides if you use more than one spray per nostril.
  • Wait at least 15 minutes before using the prescription nasal spray if you also use a saline spray or sinus rinse. This will allow the saline to completely drain. 

Your Care with Me

If you have seasonal allergies or another type of allergy that affects your eyes, talk to your personal physician or allergy specialist about managing your symptoms. If your eyes are still bothering you, your optometrist or personal physician can facilitate the process of scheduling an appointment in my department. If appropriate, she or he might call me or one of my colleagues while you are in the office so we can all discuss your care together. If we decide you need an appointment with me after that discussion, we can often schedule it the same day or soon thereafter.

During your office visit, we will discuss your medical and family history and I will perform a physical exam. I will explain the findings of your exam and answer any questions or concerns you may have. We will discuss treatment options, such as prescription eyedrops and lifestyle changes, to help you to avoid or alleviate things that may trigger your symptoms. Together we will create a treatment plan that is right for you.

If you need to talk with me after your visit or procedure, please call my office. You can also e-mail me with nonurgent issues from this website whenever it is convenient for you.

If you have urgent concerns or issues while my office is closed, or need general medical advice, you can call the Appointment and Advice line, available 24 hours a day, 7 days a week. You will be connected with a nurse who can give you immediate advice.

If you are experiencing an emergency, call 911 or go to the nearest Emergency Room.

Coordinating Your Care

Having all of our Kaiser Permanente departments located together or nearby, including pharmacy, laboratory, radiology, and health education, makes getting your care easier for you.

Another major benefit is our comprehensive electronic medical record system, which allows all of the doctors and clinicians involved in your care to stay connected on your health status and collaborate with each other as appropriate.

When every member of the health care team is aware of all aspects of your condition, care is safer and more effective.

If you come to an office visit
  • At the beginning of your visit, you will receive information about when you are due for your next test, screening, or immunization. We can discuss and schedule any preventive tests that you need. 
  • At the end of your visit, you may receive a document called the "After Visit Summary" that will summarize the issues we discussed during your visit. You can refer to it if you forget what we discussed. You can also view it online under Past Visits.
  • To help you prepare for your visit, please see additional details under Office Visit. 
If I prescribe medications

We will work together to monitor and assess how your medications are working and make adjustments over time. Prescriptions can be filled at any Kaiser Permanente pharmacy. Just let me know which pharmacy works best for you, and I will send the prescription electronically in advance of your arrival at the pharmacy.

If refills are needed in the future, you can:
  • Order them online or by phone. Order future refills from my home page or by phone using the pharmacy refill number on your prescription label.
  • Have them delivered to you by mail at no extra cost. Or you can pick up your medications at the pharmacy. If no refills remain when you place your order, the pharmacy will contact me regarding your prescription.
If lab testing or imaging is needed

For lab tests, I will use our electronic medical record system to send the requisition to the Kaiser Permanente laboratory of your choice. For imaging procedures, we will schedule an appointment with the Radiology department. When the results are ready, I will contact you with your results by letter, secure e-mail message, or phone. In addition, you can view most of your laboratory results online, along with any comments that I have attached to explain them.

If I refer you to another specialty colleague

If we decide together that your condition would also benefit from the care of other types of specialists, our staff will help arrange the appointment(s) with one or more of my specialty colleagues.

If surgery or a procedure is a treatment option

I will recommend you review educational information and tools to help you prepare for your procedure or surgery. The information will often help you decide whether surgery is right for you. If you decide to have a surgery or procedure, the information will provide details about how to prepare and what to expect.

If we proceed with surgery, I will have my Surgery Scheduler contact you to determine a surgery date and provide you with additional instructions regarding your procedure. Once your surgery is scheduled, a medical colleague of mine will contact you to conduct a preoperative medical evaluation that will assure that you are properly prepared for your surgery.
