Infective conjunctivitis, commonly known as pink eye, is a highly contagious eye infection that can affect any age of people, and it spreads pretty quickly if left untreated. When this common eye disease occurs, people always feel inflammation of the conjunctiva, the thin membrane covering the white part of the eye and the inside of the eyelids. That’s why it is important to recognize  and understand infectious conjunctivitis earlier and get the appropriate treatment. 

What is Infective Conjunctivitis?

Infective conjunctivitis is caused by bacterial or viral infections that simply cause redness, irritation, and swelling of the eye. The condition can be highly contagious, and it can be easily affected by just looking at infected eyes. Although it can affect one or both eyes and may occur alongside other symptoms such as itching, watery discharge, and sensitivity to light.

Common Causes of Pink Eye

Bacterial Infection: The most common cause of bacterial conjunctivitis, often caused by Streptococcus pneumoniae, Haemophilus influenzae, or Staphylococcus aureus.
Viral Infection: The majority of cases of viral conjunctivitis are caused by adenoviruses, though other viruses can also be responsible.
Allergic Reactions: Though not infectious, allergic conjunctivitis can have similar symptoms but is triggered by allergens.
Irritants: Exposure to chemicals, smoke, or foreign bodies can cause conjunctivitis-like symptoms.

Symptoms of Infective Conjunctivitis

Pink eye symptoms vary depending on whether the infection is viral or bacterial, but most cases share common signs. Here are the primary symptoms to watch for:

1. Redness and Swelling

The eye may appear bloodshot or red due to inflammation of the blood vessels in the conjunctiva. Swelling of the eyelids is common.

2. Watery or Thick Discharge

Viral Conjunctivitis: Clear, watery discharge that may make the eyelids stick together, especially in the morning.
Bacterial Conjunctivitis: Thick, yellow or greenish discharge that can accumulate in the corners of the eyes and cause crusting.

3. Itching or Burning Sensation

An itchy feeling in the eyes, along with a burning sensation, is typical of both bacterial and viral pink eye.

4. Sensitivity to Light (Photophobia)

Some individuals experience heightened sensitivity to bright lights.

5. Gritty Feeling

A sensation like something is in the eye, commonly referred to as "grittiness," is often reported.

6. Swollen Lymph Nodes

In some cases, viral conjunctivitis can lead to swollen lymph nodes near the ears or jaw.

How is Infective Conjunctivitis Diagnosed?

1. Physical Examination

The diagnosis of infective conjunctivitis begins with a thorough eye exam. An eye care professional will inspect the eyes to look for the typical symptoms, such as redness, swelling, and discharge.

2. Medical History

Your doctor will ask about recent exposure to someone with conjunctivitis, as well as any additional symptoms like a cold or sore throat, which could indicate a viral cause. They may also inquire about any underlying health conditions or allergies.

3. Laboratory Tests

In some cases, especially when the diagnosis is unclear or the infection is severe, your doctor may take a sample of the discharge and send it to a lab for testing. This helps determine if the infection is bacterial or viral and which specific bacteria or virus is responsible.

Treatment Options for Infective Conjunctivitis

1. Viral Conjunctivitis Treatment

Self-Limiting: Viral conjunctivitis usually resolves on its own within 1–2 weeks. Treatment focuses on alleviating symptoms.
Antiviral Medications: If the conjunctivitis is caused by the herpes simplex virus, antiviral medication may be prescribed.
Symptomatic Relief: Use cold compresses to soothe the eyes and artificial tears to reduce irritation.
Avoid Contagion: Practice good hygiene, such as washing hands frequently, to prevent spreading the infection.

2. Bacterial Conjunctivitis Treatment

Antibiotic Eye Drops or Ointments: Bacterial conjunctivitis typically requires antibiotic treatment, usually in the form of eye drops or ointments. These can help reduce the severity of symptoms and speed up recovery.
Oral Antibiotics: In some cases, oral antibiotics may be prescribed if the infection is more severe or affects deeper structures in the eye.

3. General Care for Both Types

Maintain Good Hygiene: Wash your hands frequently and avoid touching or rubbing your eyes.
Do Not Share Personal Items: Avoid sharing towels, pillows, or makeup to prevent transmission of the infection.
Clean Your Eyelids: Gently clean the eyelids and lashes with a damp cloth to remove crusty discharge.

How to Prevent the Spread of Pink Eye

Since infective conjunctivitis is highly contagious, it’s essential to take steps to reduce the risk of spreading the infection to others:

Stay Home from Work or School: If you have pink eye, stay home until the symptoms have resolved, especially if you are contagious.
Practice Proper Hand Hygiene: Wash your hands often, especially after touching your eyes.
Dispose of Tissues and Wipes Immediately: When wiping your eyes, use tissues or wipes and discard them promptly.
Disinfect Surfaces: Clean common surfaces, such as doorknobs and shared electronics, to prevent cross-contamination.

When to See a Doctor

Although pink eye is often mild, there are times when it’s important to seek medical attention:

Severe Pain or Vision Problems: If you experience significant eye pain or blurred vision, consult an eye doctor.
No Improvement with Treatment: If the symptoms worsen or don’t improve within a few days, you may require a different treatment.
Suspected Complications: If you notice increased sensitivity to light or swelling around the eye, it could be a sign of a more serious condition requiring medical intervention.
