Conjunctivitis Quiz

Comprehensive Guide to Conjunctivitis (Pink Eye)

Conjunctivitis, commonly known as pink eye, is an inflammation or infection of the transparent membrane (conjunctiva) that lines the eyelid and covers the white part of the eyeball. When small blood vessels in the conjunctiva become inflamed, they’re more visible, causing the whites of the eyes to appear reddish or pink. This guide, supported by our quiz, helps you understand its causes, symptoms, and treatments.

What is Conjunctivitis?

The conjunctiva is a thin, clear layer that protects the eye. Inflammation can be caused by viruses, bacteria, allergens, or irritants. While it can be alarming due to its appearance, pink eye is typically a minor eye condition and rarely affects vision, especially if detected and treated early. Understanding the type of conjunctivitis is key to proper management.

Types of Conjunctivitis

There are three primary types of conjunctivitis, each with a different cause and treatment approach:

• Viral Conjunctivitis: The most common type, highly contagious, and caused by viruses similar to those that cause the common cold. It usually starts in one eye and spreads to the other.
• Bacterial Conjunctivitis: Also highly contagious, caused by bacteria. This type often produces a thick, yellow-green discharge that can cause the eyelids to stick together.
• Allergic Conjunctivitis: Not contagious. It’s caused by an allergic reaction to substances like pollen, dust mites, or pet dander. It typically affects both eyes and is characterized by intense itching, tearing, and swelling.

Common Symptoms

Symptoms can vary depending on the cause, but they often include:

• Redness or pinkness in the white of one or both eyes
• A gritty feeling in one or both eyes
• Watery or thick discharge that forms a crust during the night
• Itching, irritation, and/or burning
• Swelling of the eyelids
• Increased sensitivity to light (photophobia)

Diagnosis and When to See a Doctor

A doctor can usually diagnose conjunctivitis based on an eye examination and a review of your symptoms. In some cases, a sample of eye discharge may be collected for laboratory analysis to determine the exact cause (viral vs. bacterial). You should see a doctor if your symptoms are severe, if you wear contact lenses, or if your condition doesn’t improve after a few days of self-care.

Treatment Options

Treatment is tailored to the specific type of conjunctivitis. For viral cases, the infection usually runs its course in one to three weeks without medication, with treatment focusing on symptom relief (e.g., cool compresses). Bacterial conjunctivitis is typically treated with antibiotic eye drops or ointments. Allergic conjunctivitis responds to antihistamine eye drops and avoiding the allergen.

Prevention Strategies

Since viral and bacterial conjunctivitis are highly contagious, good hygiene is the best prevention method. Key strategies include:

• Washing your hands frequently and thoroughly with soap and water.
• Avoiding touching or rubbing your eyes.
• Not sharing towels, pillowcases, eye makeup, or eyeglasses.
• Cleaning eyeglasses and contact lenses as instructed.
