What is Commonly Misdiagnosed as Pink Eye

What is Commonly Misdiagnosed as Pink Eye (Conjunctivitis)? Understanding Symptoms & Treatments

Conjunctivitis, commonly referred to as "pink eye," is a medical condition characterized by the inflammation and infection of conjunctiva. This transparent, thin membrane covers both the white part of the eyeball and the interior surface of the eyelids. Inflammation in this sensitive layer causes the tiny blood vessels within the conjunctiva to become irritated and more prominently visible, resulting in the eye taking on a pinkish hue.

Although viral infections commonly cause conjunctivitis, bacterial infections or allergic reactions, such as allergic conjunctivitis, can also be responsible for the condition. Allergic conjunctivitis refers specifically to inflammation triggered by an allergic reaction. It's important to distinguish between these different causes since treatment approaches may differ.

It's important to recognize that various other eye conditions can display symptoms resembling those of pink eye and allergic conjunctivitis. This resemblance may sometimes result in inaccurate diagnoses and thus ineffective treatments. Therefore, if someone suspects they have allergic conjunctivitis, it is crucial to seek guidance from a healthcare provider to ensure a precise diagnosis, suitable treatment, and proper medical care.

Pink Eye or Conjunctivitis: Do You Really Have It?

Before we dig into other issues that can look like pink eye, let's look at the usual signs of pink eye itself:

  • Eye Redness in one or both eyes: The white part of the eye turns red or pink.
  • Itchy eyes: It feels like you have to scratch your eyes all the time.
  • Crust forms around the eyes at night: This can make it tough to open your eyes in the morning.
  • Tearing up: Your eyes might water a lot.
  • Sensitivity to light: Bright lights might hurt your eyes more than usual.

    What is Commonly Misdiagnosed as Pink Eye?

    It's crucial to get the right diagnosis so you can get the right treatment. Here are some conditions that often get confused with pink eye:

    1. Keratitis

    Keratitis is when the clear part at the front of your eye, called the cornea, gets inflamed. This can happen if you wear bad contact lenses or swim in water with too many chemicals.



    • Red and puffy eyes
    • Gooey stuff coming out of the eye
    • Vision is foggy or blurry
    • Eye feels like there is something in it
    • Itching and irritation
    • Trouble seeing clearly


    Doctors usually give special eye drops that have medicine like:

    • Castor Oil: Contains ricinoleic acid, known for its anti-inflammatory benefits, helping to reduce eye swelling.
    • Cold Compress: Effective in reducing inflammation and swelling stemming from eye infections or injuries.
    • Green Tea Bags: Green tea bags have potent anti-inflammatory and soothing qualities.

    You'll also need to go back to the eye doctor to check how you're doing.

    2. Allergies

    We know that viruses, bacteria, or allergies mainly cause pink eye. However, its symptoms can be similar to those of conjunctivitis, making it easy to mistake one for the other. 



    • Red eyes
    • Watery and itchy eyes
    • Burning feeling
    • Crust can form around the eyes at night


    The best way to deal with eye allergies is to stay away from what's causing them. Over-the-counter allergy medicine usually works too.

    3. Iritis

    Iritis is mainly caused by an infection in the eye's middle layer, known as the 'uvea,' which sits between the white part of the eye and the retina. While it's the most common form of uveitis, its cause is often unknown.

    It may be linked to autoimmune diseases or body-wide inflammation. Like Keratitis, Iritis is a serious condition that requires immediate attention.

    The key difference between iritis and conjunctivitis (pink eye) is that iritis involves inflammation in a specific part of the eye, while in pink eye, the entire eye is affected.



    • The eye hurts and turns red
    • Blurry vision
    • Light hurts your eyes
    • Pupil might look weird or small

    Treatment Doctors usually give eye drops with steroids in them. Sometimes, you might also need to take pills.

    4. Styes

    Styes, also called hordeolum, is often confused with pink eye because they share symptoms like redness, itching, and watery discharge. However, styes have a unique feature: a small pimple-like bump. A bacterial infection causes this bump and comes in two forms.

    1. External Hordeolum: A bump at the base of the eyelash, can give foreign body sensation.
    2. Internal Hordeolum: A bump inside the eyelid's oil gland, may look like swollen eyelids.

    In styes, the eye discharge is thicker than in pink eye, and it can create crusts that make it hard to open the eyes. Additionally, the bump and thicker tears can make the eye appear droopy.



    • The eyelids hurt and might be red
    • Gooey stuff can come out
    • Vision might get blurry
    • Feels like something's stuck in your eye


    • Use warm clothes on your eyelid
    • Keep your eyelids clean
    • Sometimes, the doctor might give you antibiotic drops or ointment

    5. Blepharitis

    Blepharitis is a condition that affects your eyelids, making them red and swollen. It usually happens because tiny oil glands near the base of your eyelashes get blocked. This is different from pink eye, which mainly impacts the clear front part of your eye, known as the cornea.



    If you have blepharitis, you might notice:

    • Red or puffy eyelids
    • Itchy or uncomfortable eyes
    • Crusty stuff forming on your eyelids
    • Your eyelids might stick together
    • Foamy tears
    • Light Sensitivity, Light could bother you more than usual
    • You might have blurred vision


    If you think you have blepharitis, here are some common treatments:

    1. Keep Your Eyelids Clean: Using warm water and a gentle cleanser, lightly wash your eyelids. Some doctors might also prescribe special eyelid scrubs.
    2. Warm Compress: A warm cloth held against your eyes can help soften crusts and make your eyelids feel better.
    3. Antibiotics: If there’s an infection, your doctor might give you antibiotic ointments, drops, or even pills.
    4. Lubricating Ointments: These can help if you have dry eyes along with blepharitis.
    5. Regular Check-Ups: It’s important to regularly see an eye care professional to make sure your treatment is working.

    6. Dry Eye

    People with dry eyes often have red eyes, similar to those with pink eye. Many try to treat their red eyes with over-the-counter drops, including redness reducers.

    However, dry eye is a long-term condition and should not be mistaken for a less serious issue like pink eye. If you're experiencing symptoms similar to dry eye, it's important to consult your doctor for proper diagnosis and treatment. 

    Dry Eye


    • Eyes feel dry and might turn red
    • Burning or irritation
    • Even though it's called "dry" eye, sometimes your eyes might actually water a lot


    • Use fake tears (lubricating eye drops)
    • Keep your eyelids clean
    • Take breaks when doing things like reading or looking at a screen for too long.

    How Long Does Pink Eye Last?

    If a viral infection causes pink eye, it usually goes away on its own in 7 to 14 days. Sometimes, it can take up to 3 weeks to fully clear up. No long-term effects are generally expected, and it often doesn't require treatment.

    However, if pink eye is due to a bacterial infection, it's important to take antibiotics. Without proper treatment, the condition could last longer and potentially harm your eyes.

    When Should You See a Doctor?

    If you're experiencing prolonged or severe pink eye symptoms, it's important to consult your healthcare provider. They can properly diagnose the condition and may refer you to a specialist for a more targeted treatment plan. 


    Though viral conjunctivitis and bacterial conjunctivitis share common eye infection symptoms like redness, swelling, and itchiness, they differ in the type of eye discharge they produce. Viral conjunctivitis often results in a thin, watery discharge, while bacterial conjunctivitis tends to have a thicker, more substantial yellow discharge. It's important to note that Viral conjunctivitis can be highly contagious and can spread quickly, especially in environments like schools and workplaces.

    Treatment strategies also vary is based on the type of conjunctivitis. For Viral conjunctivitis, the condition usually resolves on its own and focuses on symptom relief, whereas bacterial conjunctivitis may necessitate the use of antibiotic eye drops or ointments.

    Since the presentations of these two types can be similar, and given the contagious nature of Viral conjunctivitis, if you experience any persistent or severe eye symptoms, consulting a healthcare provider is essential. They will be able to differentiate between bacterial and Viral conjunctivitis and guide the proper diagnosis and treatment course.


    My eye feels like there is something in it. Could it be pink eye?

    While a sensation that feels like something is in your eye can be disconcerting, it may not necessarily indicate pink eye or infectious conjunctivitis. This symptom is more commonly associated with a condition known as Keratitis. In Keratitis, the cornea—the clear front part of the eye—becomes inflamed.

    Other symptoms can include red and puffy eyes, discharge, foggy or blurry vision, itching, and irritation. These symptoms might sometimes be confused with those of infectious conjunctivitis.

    If you experience a sensation as if something is stuck in your eye, or if you suspect you might have infectious conjunctivitis, it is essential to consult a healthcare provider for a proper diagnosis and treatment plan.

    Are there any tests to confirm if it's really pink eye and not something else?

    Yes, healthcare providers can carry out specific tests to diagnose pink eye accurately. They may collect a sample of eye discharge to send to a lab for bacterial or viral identification.

    In more complex cases, imaging tests or biopsies could be required. These tests help in distinguishing pink eye from other common conditions with similar symptoms.

    Can diet and lifestyle changes help in alleviating symptoms that are commonly mistaken for pink eye?

    Interestingly, diet and lifestyle can impact eye health. For instance, a diet rich in omega-3 fatty acids has been shown to help alleviate dry eye symptoms. Similarly, quitting smoking and reducing screen time can contribute to better eye health.

    While these changes are not a substitute for professional medical treatment, they can complement existing therapies.

    Is it possible to prevent conditions that are often misdiagnosed as pink eye?

    Prevention methods may vary depending on the specific condition. For example, maintaining good eye hygiene can prevent bacterial forms of Keratitis, while avoiding allergens can help in preventing allergy-related eye symptoms.

    Regular eye check-ups are also crucial in early identification and treatment of eye conditions.

    What role do over-the-counter eye drops play in treating symptoms similar to pink eye?

    Over-the-counter eye drops, often known as artificial tears, can offer temporary relief from irritation or dryness but are not a cure for conditions that are commonly misdiagnosed as pink eye.

    Some of these drops may contain preservatives or other substances that can exacerbate symptoms if used inappropriately. It's crucial to consult a healthcare provider for a proper diagnosis and treatment plan before relying solely on over-the-counter solutions.
