Eye Flu (Conjunctivitis): Causes, Symptoms, Treatment, and Home Remedies

Introduction

Conjunctivitis, more commonly referred to as eye flu, is a highly communicable eye infection characterised by irritation and inflammation of the organ. Furthermore, it is transmitted and may spread from one individual to another easily, regardless of whether it is caused by a virus, bacteria, or allergens, particularly in crowded places. Therefore, it is very important to recognise the disease at an early stage and learn the ways of treatment and prevention of the disease for maintaining good health and well-being of the eyes. The article explains the cause and symptoms, their effective treatments, and home remedies that would help you keep up and recover from this annoying state of your eye.

What is Eye Flu?

Eye flu, or conjunctivitis flu, is an inflammation of the conjunctiva, a thin and transparent membrane that covers the white portion of each eye and lines the inside of the eyelids. It is a very infectious and pretty common disease that could easily get transmitted from one person to another in crowded places. The flu in the eyes can be caused by viruses, bacteria, allergens, and other irritants. These will make one’s eyes ache and appear red.

Causes of Eye Flu

The eye flu causes depend on the type of conjunctivitis involved. The most common cause is a viral eye infection, often concurrent with an upper respiratory infection like the flu or common cold. Bacterial infection, allergens like pollen or dust or pet dander, and even irritants such as smoke or chemicals may also lead to conjunctivitis. The conjunctivitis determines what kind of treatment to apply.

Symptoms and Signs of Eye Flu (Conjunctivitis)

Eye flu symptoms include some signs that define the ailment. A few of the key symptoms of Eye Flu include:

• Redness: The eyes turn red and bloodshot due to inflammation.
• Itchiness: Commonly, a person feels itchiness in the eye.
• Lacrimation: Excessive watering or tearing of the watery eye is always experienced.
• Grittiness: Many people will feel like there is sand or grit in their eyes.

Among others, additional symptoms of Eye Flu include:

• Discharge: A sticky discharge is formed which crusts at night, making the eyes sticky in the morning.
• Swollen Eyelids: The eyelids swell, further irritating the eyes.
• Photophobia: Lighting becomes particularly irritating or painful; this may include squinting or shutting the eyes frequently.
• Blurred Vision: Vision may blur due to temporary irritation/discharge.

These symptoms help to distinguish eye flu from the rest of the eye conditions. Therefore, identification of these signs at the early stage enables timely treatment, preventing the condition from getting out of hand and spreading to others.

Diagnosis of Eye Flu

Eye flu diagnosis is mainly based on symptoms and physical examination of the eyes. A health expert may also swab the discharge of the eye to tell whether it is a viral or bacterial infection. This helps in choosing the most effective treatment plan to be initiated.

Treatment Options for Eye Flu

Eye flu treatment depends on the cause. The eye flu caused by bacteria may require an antibiotic prescription, while the viral conjunctivitis most often improves by itself with only supportive care. For allergic conjunctivitis, antihistamines and avoiding the allergen can manage it.

Medical Treatment For Eye Flu

Medical treatment for pink eye includes prescription eye flu medicine, such as antibiotic eye drops or ointments for bacterial pink eye. Here are some options for you:

• Antibiotic Eye Drops or Ointments: For bacterial conjunctivitis, a doctor may prescribe antibiotic eye drops or ointments to treat the infection. It’s important to use the medicine exactly as prescribed and finish the full course to make sure the infection is fully cleared. Some commonly prescribed antibiotics in India for treating bacterial conjunctivitis include Ciprofloxacin, Moxifloxacin, Ofloxacin, Chloramphenicol, and Gentamicin. These medications are effective in clearing the infection by targeting the bacteria responsible for the condition.
• Antiviral Medications: In severe cases of viral conjunctivitis, doctors may prescribe antiviral medications to help manage the infection. Some common examples include Acyclovir, and Ganciclovir.
• Antihistamines or Decongestants: If allergies are causing the eye flu, antihistamine eye drops or oral medicine can help reduce symptoms by calming the allergic reaction. Decongestant drops can also be used to ease redness and swelling. Examples include combination medicines like Alcaftadine + Benzalkonium Chloride.
• Steroid Eye Drops: In cases of severe eye inflammation, steroid eye drops may be given to reduce swelling and discomfort.
• Artificial Tears or Lubricants: Over-the-counter artificial tears can help soothe dry and irritated eyes. You can use these drops several times a day to keep your eyes moisturized and comfortable. Some common examples include Carboxy Methyl Cellulose or Sodium Carboxymethyl Cellulose.

Home Remedies for Eye Flu

Eye flu treatment at home would only require some simple but quite effective steps. Here are some steps to follow:

• Warm Compresses: Applying a warm compress can soothe discomfort and reduce inflammation.
• Artificial Tears: Using artificial tears helps prevent dryness and keeps the eyes moisturized.
• Good Hygiene Practices: Frequent handwashing and avoiding touching or rubbing the eyes are crucial to prevent the spread of infection.
• Adequate Home Care: For mild cases, these home remedies for eye flu can be effective in managing symptoms and promoting recovery.

Eye flu prevention is very important not only to prevent the spread of the infection to others but also to prevent its worsening in the case of an infected patient. Here are a few essential tips:

• Wash Your Hands: The simplest and most effective way of preventing the eye flu from spreading due to a virus or bacteria is frequent handwashing.
