Eye Flu (Conjunctivitis) - Symptoms, Causes & Treatment

Eye flu, also known as conjunctivitis or pink eye, is a common eye condition. It affects one or both eyes. This highly contagious condition can spread from person to person through direct contact.

Eye flu is a common problem experienced by individuals during monsoons, causing various uncomfortable symptoms. It is characterized by an inflammation or infection of the conjunctiva.

What is conjunctiva? It is a thin and transparent tissue layer that covers the front surface of the eye and lines the inner surface of the eyelids.

Eye flu, or conjunctivitis, can be categorised into several types based on its underlying cause. It is crucial to identify the type to plan a treatment approach. The main types of eye flu include:

1. Viral Eye Flu: This is the most common type caused by a viral infection. Viral eye flu is highly contagious and can quickly spread from one eye to another. 

2. Bacterial Eye Flu: This type is caused by bacteria that usually affects one eye but can develop in both. 

3. Allergic Eye Flu: It can occur due to allergens like pollen. This may lead to intense itching and redness in both eyes. Individuals may experience eye flu symptoms like scratchy throat, itchy nose, and sneezing. 

4. Ophthalmia Neonatorum: This type affects newborn babies and can be caused by bacterial infections acquired during childbirth. It requires prompt medical attention to prevent complications. 

5. Giant Papillary Conjunctivitis: It is an inflammatory condition often associated with the long-term use of contact lenses and an artificial eye.

Eye flu symptoms can vary from one person to another, depending on the underlying cause of the condition. However, some common symptoms of eye flu include:

1. Redness: The white of the eye may appear pink or red due to inflammation of the conjunctiva.

2. Increased Tearing: Inflammation or irritation of the conjunctiva can increase tear production. 

3. Itching: One or both eyes may feel itchy, especially in eye flu caused by allergies. 

4. Gritty Feeling: Eye flu may cause discomfort and the sensation of foreign particles in one or both eyes. 

5. Irritation: People may experience burning eyes if chemicals like acids or cleaning solutions and irritants like chlorine cause eye flu. 

6. Thick Discharge: In cases of bacterial eye flu, there may be a yellow or greenish discharge that causes the eyelids to stick together, especially after waking up.

7. Blurred Vision: The vision may be temporarily impaired in severe cases or when the cornea becomes affected.

8. Sensitivity to Light: Some individuals may experience photophobia or sensitivity to light. It happens due to inflammation of the conjunctiva and surrounding eye tissue.

9. Swelling: Eye flu infection may cause swollen eyelids, especially in the morning. 

Understanding the reason for eye flu is crucial for proper treatment and preventing its spread. The following are the eye flu causes that may result in inflammation of the blood vessels in the eye:

1. Viruses: Viral infections are the most common cause of eye flu infections. Common cold viruses, like adenoviruses, can cause this condition. Viral infections are highly contagious that mostly affect children. 

2. Bacteria: Bacterial eye flu infection can be caused by different bacteria, such as:

1. Staphylococcus aureus

2. Streptococcus pneumoniae

3. Haemophilus influenzae

4. Pseudomonas aeruginosa

   It is also contagious and can spread through direct contact. Adults are more prone to bacterial infections. 

3. Allergens: Allergic eye flu results from exposure to allergens like:

1. Pollen

2. Pet dander

3. Dust mites

4. Other substances that cause allergies

4. Irritants: Eye flu may occur when the eyes come into contact with irritating substances like:

1. Smoke

2. Pool chlorine

3. Dirt

4. Shampoos

5. Cosmetics

6. Contact lenses

7. Other chemicals

5. Sexually Transmitted Infections: STIs like herpes simplex, gonorrhoea, or chlamydia can cause eye flu in newborns and adults. It occurs when the infection is transmitted to the eyes through direct contact.

6. Foreign Object: If a foreign object, like dust, sand, or eyelashes, enters the eye, it can scratch or irritate the conjunctiva. This can lead to inflammation or infection.

7. Blocked Tear Ducts: When a tear duct becomes blocked, tears build up on the eye’s surface, causing irritation. The buildup of tears can increase the risk of bacterial infections, leading to eye flu. It is most common in babies.

8. Autoimmune Conditions: Rare causes of eye flu may include autoimmune diseases like:

1. Rosacea (a skin condition causing redness on the face) 

2. Kawasaki disease (inflammation in blood vessels throughout the body)
   
   In these diseases, the body’s immune system mistakenly attacks the healthy tissues in the eye.

Eye Flu Infection Risk Factors

Certain factors can increase the risk of getting an eye flu infection. Knowing these risk factors can help individuals take preventive measures and seek timely medical attention. The risk factors of eye flu include:

1. Exposure to Infected Individuals: Close contact with someone with viral or bacterial eye flu increases the risk of contracting the infection.

2. Allergies: Individuals with a history of allergies are more susceptible to allergic eye flu if exposed to allergens.

3. Contact Lens Use: Wearing contact lenses, especially if not properly cleaned or fitted, can increase the risk of developing giant papillary conjunctivitis.

4. Poor Hygiene: Touching eyes with unwashed hands or using contaminated items can facilitate the spread of eye flu infection.

Certain preventive measures can significantly reduce the risk of contracting eye flu. To prevent eye flu and reduce the risk of infection, consider the following measures:

1. Practice Good Hygiene: Individuals should wash their hands frequently with soap and water. This should be especially done after touching their eyes, blowing their nose, or applying eye drops to the eyes. 

2. Avoid Touching the Eyes: Refrain from touching or rubbing the eyes. Touching the eyes can spread the infection from one eye to another.

3. Use a Clean Towel: One should always use clean towels and washcloths to wipe their face and eyes. 

4. Use Personal Items: Do not share personal items like towels or eye makeup with others, as these can transfer germs and increase the risk of infection.

5. Wash Pillowcases Regularly: Clean the pillowcases regularly to prevent the spread of viruses and bacteria. 

6. Stay Away from Infected Individuals: Avoid close contact with individuals with eye flu symptoms until they are no longer contagious. 

7. Contact Lens Care: If individuals wear contact lenses, they must follow the hygiene and cleaning instructions their eye care professionals provide to reduce the risk of infection.

It is usually not difficult for healthcare professionals to diagnose eye flu. Diagnosing eye flu typically involves a thorough eye examination and a review of the individual’s medical history. Sometimes, the doctor may perform a few tests to diagnose the condition. These tests may include:

1. Culture: Includes taking a sample of the eye’s discharge and analysing it to determine the cause of the infection 

2. Vision Test: To check whether the vision has been affected

3. Examination of External Eye Tissue: Involves the use of bright light and magnification to examine the external eye tissue

4. Inner Eye Examination: To ensure that no other tissues are affected

How to Prepare for the Doctor’s Appointment?

Patients must start by seeing their regular healthcare provider if they experience eye-related symptoms. The doctor may refer them to an ophthalmologist (eye specialist) if the symptoms worsen. Preparing for a doctor’s consultation for eye flu can help ensure that patients make the most of their appointment. Here’s how patients can prepare:

1. Take a Prior Appointment: Patients must make an appointment beforehand and ask for any pre-appointment restrictions. This may include refraining from using eye drops or stop wearing contact lenses. 

2. Write Down the Symptoms: Pay close attention to the eye flu symptoms, like redness, itching, discharge, and vision changes. Note the duration and severity of each symptom and any factors that worsen or improve the condition.

3. Note the Medications: Patients are advised to list any medications they are currently taking, including eye drops or other eye-related treatments. If they wear contact lenses, they must inform the doctor, as this may be relevant to the diagnosis.

4. Gather Medical History: Individuals must be ready to provide their medical history, including any previous eye conditions or allergies they may have had. They must also mention a family history of autoimmune diseases, recent illnesses or exposure to individuals with eye infections.

5. Write Down Questions: Patients must prepare a list of questions or concerns about eye flu. This will help them ensure they address all their queries.

What to Expect from the Doctor?

During an eye flu appointment, the doctor will likely ask various questions to gather relevant information about the patient’s condition. Some common questions to expect include:

1. What symptoms do you experience, and when did they start?

2. How severe are the symptoms?

3. Have your eye flu symptoms been continuous or occasional?

4. Does anything seem to improve or worsen your symptoms?

5. Are these symptoms affecting one or both eyes?

6. Have you been in contact with anyone who has had an eye infection recently?

7. Do you wear contact lenses? If so, how do you care for them?

8. How often do you replace the storage case of your contact lenses?

9. Are you currently taking any medications or using any eye drops?

10. Do you have a family history of autoimmune disorders?

Questions to Ask the Doctor

Patients must ask the doctor relevant questions to understand their condition and the recommended treatment better. Here are some questions they may consider asking:

1. What is the cause of my eye flu, and is it contagious?

2. What type of eye flu do I have?

3. What tests do I need?

4. What are the best treatment options for my specific type of eye flu?

5. How long is the expected duration of the eye flu, and when can I expect improvement?

6. Are there any specific eye drops or medications you recommend? 

7. How should I use these medications?

8. Are there home remedies or self-care measures to ease the symptoms and promote healing?

9. How can I keep my eye flu from spreading?

10. Are there any potential complications or warning signs I should watch out for?

11. Do I need to come back for a follow-up?

Most cases of mild to moderate eye flu can resolve on their own without treatment. Patients may require treatment if their eye flu is severe. The treatment of eye flu depends on the underlying cause, whether it’s viral, bacterial, allergic, or due to irritants. 

Here are some common treatment approaches:

1. Eye Flu Caused by Virus: Most cases of viral conjunctivitis are self-limiting and do not need treatment. People may need treatment when their eye flu is caused by viruses like herpes simplex, varicella-zoster, or sexually transmitted infections. These infections can scar the eye if left untreated or lead to vision loss. Treatment for these viruses may include:

1. Antiviral medications

2. Warm compresses to help soothe discomfort

2. Eye Flu Caused by Bacteria: Antibiotics (eye drops, ointments, or pills) are the most common treatment for bacterial conjunctivitis. While adults prefer eye drops, ointments are a better choice for children due to their ease of use. It is recommended to follow the prescribed treatment regimen and finish the full course of antibiotics even if symptoms improve. 

3. Eye Flu Caused by Allergies: Avoiding exposure to allergens is key in managing allergic conjunctivitis. Treatment for this type of eye flu may include:

1. Prescription or over-the-counter eye drops such as antihistamines (loratadine, diphenhydramine) to stop allergic reactions or anti-inflammatory drugs like steroids. 

2. Cold compresses on closed eyes to get soothing relief from inflammation

4. Eye Flu Caused by Irritants: The best treatment for eye flu caused by irritants or chemicals is rinsing the eye with water for five minutes. Patients should seek immediate medical attention if exposure to a harmful chemical occurs.

   Please Note: The selection of the treatment approach is based on the type of eye flu, the patient’s condition and the treating doctor’s opinion. 

Lifestyle and Home Remedies for Eye Flu Infection

While home remedies cannot cure the underlying cause of eye flu, they can relieve symptoms and aid healing. Here are some lifestyle and home remedies that may help:

1. Warm Compress: A warm compress on the afflicted eye can help reduce inflammation, irritation, and itching. Dip a clean washcloth in warm water, rinse it out, and gently apply it over the closed eye for a few minutes.

2. Cold Compress: Swelling and redness can be reduced with a cool compress. Apply a cold gel pack wrapped in a soft cloth for a few minutes to the closed eye. However, do not touch both eyes with the same clothes, as it can increase the risk of spreading infection from one eye to another. 

3. Eye Drops: Artificial tears are over-the-counter eye drops designed to lubricate the eyes and treat dryness, irritation, and pain. While they do not address the underlying cause of eye flu, they can temporarily relieve the gritty sensation that some people may experience.

4. Stop Using Contact Lenses: If someone has eye flu, they should avoid wearing contact lenses until their symptoms have completely resolved. Using contact lenses during conjunctivitis can worsen the condition and delay healing. 

Eye flu is typically a mild condition with no lasting problems. However, some forms of eye flu can lead to complications in certain cases. Possible complications of eye flu include:

1. Keratitis: It is an inflammation of the cornea that occurs due to viral or bacterial eye flu. Keratitis may cause corneal ulcers and vision problems if not promptly treated.

2. Bacterial Superinfection: Eye flu can weaken the eye’s natural defenses, making it more susceptible to secondary bacterial infections.

3. Conjunctival Scarring: Eye flu infection can cause prolonged inflammation and damage to the conjunctival tissues. Over time, this can lead to scarring of the conjunctiva, potentially leading to visual disturbances or discomfort.

4. Chronic Infection: If the underlying cause of eye flu is not effectively treated, it can become chronic. Chronic infection may cause persistent or recurrent symptoms. 

When to See a Doctor?

Eye flu can have various underlying causes, and proper diagnosis is vital to determine the most appropriate treatment. Some eye flu symptoms can indicate a serious condition like a corneal ulcer. Patients should call their healthcare provider right away if they experience the following:

1. Severe eye pain

2. Increased light sensitivity

3. Blurred or decreased vision

4. A feeling of having something stuck in the eye

5. A large amount of yellow or green discharge from the eyes

6. Other worsening symptoms

There is no specific diet specifically for eye flu treatment. However, a well-balanced and nutritious diet can support overall eye health and immune function, aiding recovery. Here are some dietary tips that may be beneficial during eye flu.

1. Hydration: Stay well-hydrated by drinking plenty of water. Proper hydration may promote faster recovery.

2. Vitamin A: Foods high in vitamin A are essential for eye health. Sources of these foods include carrots, spinach, kale, and other leafy greens.

3. Vitamin C: It is an antioxidant that supports the immune system and can help with healing. Some excellent sources of vitamin C include citrus fruits, strawberries, kiwi, and bell peppers.

4. Vitamin B12: This vitamin can help balance immune responses to fight viral infections. Sources include leafy greens, citrus fruits, milk, almonds, and tomatoes. 

5. Zinc: It is crucial for maintaining a healthy immune system. Foods like nuts, seeds, legumes, dairy products, meat, and whole grains are good sources of zinc.

6. Probiotics: These can help support gut health and overall immunity. Probiotics can be found in yoghurt and other fermented foods. 

Food items that people must not consume during eye flu include:

1. Bread

2. Pasta

3. Processed meat

4. Fried food

5. Sugary food like pastry, pies, etc. 

6. Sugary drinks
