Conjunctivitis (Pink Eye)

What Is Conjunctivitis (Pink Eye)?

Conjunctivitis, commonly known as pink eye, is an inflammation of the conjunctiva - the thin, clear layer that covers the white part of the eye and the inner surface of the eyelids. When this layer becomes irritated or infected, the tiny blood vessels inside it swell and become more visible, making the eye appear red or pink.

This condition is very common and can affect one or both eyes. It may be short-term (acute), lasting a few days to weeks or long-lasting (chronic) in some cases.

Conjunctivitis can happen due to different reasons:

• Viral infections: It is the most common cause, often linked to cold or flu.
• Bacterial infections: They cause sticky or pus-like discharge.
• Allergic reaction: It is triggered by pollen, dust or pet dander.
• Irritants: They could be smoke, pollution or chemicals.

In allergic conjunctivitis, the body reacts to substances called allergens. This triggers the release of chemicals like histamine, leading to itching, redness and watering. Unlike infectious types, allergic conjunctivitis is not contagious.

Pink eye often causes symptoms like redness, watering, itching, mild swelling and discharge. The white part of the eye may look light pink to deep red, sometimes with crusting on the eyelids, especially after sleep.

While conjunctivitis can be uncomfortable, it usually does not cause serious vision problems. However, some types, especially viral and bacterial conjunctivitis can spread easily from person to person or from one eye to the other.

Early care, proper hygiene and timely medical advice can help relieve symptoms faster and prevent the infection from spreading.

What Are the Conjunctivitis Symptoms You Should Not Ignore?

The symptoms of conjunctivitis can differ based on the cause, but many signs are common in most cases.

Common symptoms include:

• Redness: The white part of the eye looks pink or red due to swelling of tiny blood vessels.
• Swollen eyelids: The eyelids may appear puffy due to inflammation.
• Discharge: Viral conjunctivitis causes watery discharge, while bacterial infection leads to thick yellow or green discharge that may stick to the eyelashes.
• Light sensitivity: Bright light may cause discomfort or watering.
• Itching or burning: Common in allergic conjunctivitis, often with a strong urge to rub the eyes.
• Gritty feeling: A sensation like sand or dust in the eye, even when nothing is present.

If you notice these warning signs, it is important to consult an eye specialist without delay to prevent complications.

When Should You See an Eye Specialist for Conjunctivitis (Pink Eye)?

See an eye specialist (optometrist or ophthalmologist) if you have pink eye along with severe symptoms like strong eye pain, blurred vision, high sensitivity to light or thick yellow or green discharge. You should seek immediate care if symptoms worsen after 48 to 72 hours, especially if you wear contact lenses, have a weak immune system or if a newborn is affected.

You should see an eye specialist if you have:

• Severe symptoms such as strong eye pain, not just mild irritation.
• Vision changes like blurred, unclear, or reduced vision.
• Light sensitivity with pain or discomfort when exposed to bright light.
• Discharge that is thick, yellow or green and makes the eyelids stick together.
• Severe redness with deep or intense redness covering the white part of the eye.
• No improvement i.e., if symptoms do not get better or worsen after 2 to 3 days.
• High-risk conditions, including newborns, contact lens users, or people with low immunity.
• Previous injuries such as any recent eye injury or surgery. Delete the highlighted text.

While mild viral conjunctivitis may improve on its own, bacterial, allergic or severe cases usually need proper medical treatment, including medications or eye drops as advised by a doctor.

What Causes Conjunctivitis (Pink Eye)?

Conjunctivitis (pink eye) happens when the eye lining gets irritated or infected. The most common causes include viruses, bacteria, allergies and exposure to irritants like smoke or chemicals. Viral and bacterial conjunctivitis can spread easily, while allergic and irritant types do not spread.

Main causes of conjunctivitis include:

• Viral infections: This is the most common cause of conjunctivitis. Most cases are due to adenovirus, though other viruses like herpes simplex and varicella-zoster can also cause it. It is often associated with cold symptoms such as sore throat or fever and spreads easily through direct contact and respiratory droplets from coughing or sneezing.
• Bacterial infections: They are more common in children and are caused by bacteria such as Haemophilus, Staphylococcus, or It usually produces thick yellow or green discharge and spreads easily from person to person.
• Allergies: Triggered by pollen, dust, pet dander, smoke or cosmetics. It often causes intense itching and usually affects both eyes.
• Irritants: Caused by exposure to chemicals, chlorine in swimming pools, dust or foreign particles entering the eye.
• Blocked tear ducts in newborns: Babies may develop symptoms if their tear ducts are not fully open.
• Contact lens misuse: Poor hygiene, improper use or wearing lenses for too long can lead to infection or irritation.

Each cause requires a different approach to treatment, making proper diagnosis important. Seek medical care if you have severe pain, vision problems or if symptoms get worse within 1 to 2 days.

What Are the Risk Factors for Conjunctivitis (Pink Eye)?

Certain factors can increase your chances of getting conjunctivitis, especially the viral and bacterial types.

Common risk factors include:

• Close contact: Being around someone with pink eye or sharing items like towels, pillows or eye makeup increases the risk of getting the infection.
• Allergies: People with allergies like hay fever, asthma or eczema are more likely to develop allergic conjunctivitis.
• Poor hygiene: Touching or rubbing your eyes with unwashed hands increases the risk.
• Weak immune system: Conditions like diabetes or ongoing treatments can lower immunity and increase risk.
• Contact lens use: Improper cleaning, reuse or overuse of lenses increases the risk.
• Children and elderly: Children are at higher risk due to close contact in schools, while older adults may be more prone to infections.
• Environmental exposure: Contact with smoke, dust, chemicals, chlorine or allergens like pollen and pet dander increases the risk of getting the infection.
• Recent illness: Viral conjunctivitis often develops after a cold or sore throat.

Maintaining good hygiene and avoiding triggers can reduce the risk of infection.

How Is Conjunctivitis Diagnosed?

Conjunctivitis (pink eye) is usually diagnosed through a simple eye check-up by an eye doctor. The diagnosis is based on your symptoms, medical history and an examination of your eyes.

Common diagnostic tests include:

• Medical history: The doctor asks when your symptoms started, if they are getting worse and whether you’ve been in contact with someone who has pink eyes or have allergies.
• Eye examination: The eyes are checked for redness, swelling, discharge and signs of irritation using a light or magnifying tool.
• Discharge testing (if needed): In some cases, a small sample of eye discharge is taken to identify bacterial infection and guide treatment.
• Vision test: A basic eye chart test may be done to make sure your vision is not affected.
• Fluorescein staining: A special dye may be used to check for any damage or scratches on the eye surface.

Based on these findings, the doctor can determine whether the conjunctivitis is viral, bacterial, allergic or due to irritation and suggest the right treatment.

Conjunctivitis (pink eye) usually gets better without problems, but in some cases, especially if left untreated, it can lead to serious eye issues.

Possible complications include:

• Corneal inflammation (keratitis): Infection can spread to the cornea, causing pain, blurred vision and light sensitivity.
• Corneal ulcers or scarring: Severe infections may damage the cornea and affect vision.
• Chronic or recurrent infection: Symptoms may last longer or keep coming back if not treated properly.
• Vision problems: Rarely, untreated cases can lead to long-term or permanent vision loss.
• Eye inflammation conditions: Such as uveitis or deeper eye involvement in severe cases.
• Secondary (bacterial) infection: A new infection can develop on top of the existing one.
• Newborn complications: In babies, certain infections can cause serious eye damage or blindness if not treated early.

When to be careful

Seek medical care if symptoms worsen, do not improve within a few days, or if you have severe pain or vision changes. Early treatment helps prevent complications and protects your eyesight.
