Pink Eye (Conjunctivitis)
Introduction
Pink eye, also known as conjunctivitis, is a common eye condition that affects people of all ages. It occurs when the conjunctiva, the thin, transparent tissue covering the white part of the eye and lining the inner surface of the eyelids, becomes inflamed or infected. This inflammation can cause various uncomfortable symptoms and is highly contagious. In this blog, we will explore the causes, symptoms, and treatments of pink eye, providing you with essential information to understand this condition better.
Symptoms of Pink Eye
- Eye redness in the white part
- Watery or itchy eyes
- Eye discharge, which can be clear, yellow, or green
- An eye feeling of grit
- Sensitivity to light
- Eyelid swelling
- There is a feeling of crusting around the eyes, especially in the morning
Redness in the Eyes
One of the primary indicators of pink eye is the red or pink appearance of the whites of the eyes. The inflammation of the conjunctiva leads to increased blood flow, causing the eyes to take on a reddish hue. This redness may be more pronounced in some cases, depending on the severity of the infection or the underlying cause.
Itching and Irritation
Pink eye can cause intense itching and irritation in the affected eye(s). The sensation of something foreign in the eye may lead to frequent rubbing or scratching, exacerbating the discomfort. It is essential to avoid rubbing the eyes, as this can potentially spread the infection to the other eye or to others.
Watery Eyes
Excessive tearing or watery discharge is a typical symptom of pink eye, especially in viral and allergic cases. The inflammation stimulates tear production, resulting in watery eyes that may blur vision temporarily.
Eye Discharge
The type and colour of eye discharge can help differentiate the type of pink eye:
Sensitivity to Light
Pink eyes can make the eyes sensitive to light, a condition known as photophobia. Exposure to bright light may worsen the discomfort and lead to squinting or closing of the eyes.
Swollen Eyelids
Inflammation of the conjunctiva may extend to the eyelids, causing them to become swollen and puffy. Swelling can vary in severity and may affect one or both eyes.
Causes of Pink Eye
Viral Conjunctivitis: This type is commonly caused by viruses, similar to the ones that cause the common cold. Coughing, sneezing, and touching contaminated surfaces can spread the virus.
Bacterial Conjunctivitis: Bacterial infections, such as Staphylococcus or Streptococcus, are the usual culprits behind bacterial conjunctivitis. This type of pink eye can spread through direct contact with an infected person’s eye secretions.
Conjunctivitis caused by allergies: Allergens, such as pollen, pet dander, or dust mites, can trigger allergic conjunctivitis. Both eyes are typically affected by this condition, which is not contagious.
Treatments for Pink Eye
Over-the-Counter Eye Drops and Ointments
One of the most accessible and widely used treatments for pink eye is over-the-counter (OTC) eye drops or ointments. These products are formulated to relieve redness, itching, and irritation associated with pink eye. Look for preservative-free lubricating eye drops to avoid additional irritation. It may be possible to clear bacterial conjunctivitis more quickly with over-the-counter antibiotic eye drops or ointments.
Prescription Medications
In cases of severe or persistent pink eye, seeking medical attention is crucial. An eye care professional may prescribe prescription-strength eye drops or oral antibiotics to treat bacterial conjunctivitis effectively. These medications are targeted and potent, helping to resolve the infection and symptoms more rapidly.
Warm Compresses
Applying warm compresses to the affected eye can provide soothing relief and help reduce swelling. To use a warm compress, soak a clean cloth in warm water, wring out excess water, and gently place it over the closed eyelid for several minutes. Repeat this process a few times a day to alleviate discomfort.
Cold Compresses
For allergic conjunctivitis, cold compresses can be beneficial in reducing inflammation and easing itching. Use a cold pack or wrap ice cubes in a clean cloth and gently apply it to the closed eye for a few minutes. Be sure not to apply ice directly to the skin to avoid cold burns.
Avoiding Allergens
If your pink eye is triggered by allergies, identifying and avoiding allergens is essential for managing the condition. Stay indoors during high pollen counts, keep windows closed, and use air purifiers to reduce airborne allergens. Regularly wash bedding and avoid contact with pets if pet dander is the trigger.
Proper Contact Lens Care
If you wear contact lenses, practising proper hygiene and care to prevent and manage pink eye is crucial. Follow your eye care professional’s recommendations for cleaning, disinfecting, and replacing your contact lenses. In the case of pink eye, refrain from wearing contacts until the infection has cleared.
Hygiene and Prevention
Practice good hygiene to prevent pink eye from spreading. Wash your hands frequently, avoid touching your eyes, and use separate towels and linens until the infection has resolved. Encourage others to do the same, especially if pink eye is contagious in your case.
Prevention of Pink Eye
- Frequently wash hands.
- Change towels separately.
- Don’t share personal items.
- Avoid touching the eyes.
- Throw away cosmetics used while infected.
- Replace your contact lenses as recommended, and follow proper hygiene practices.
- Stay away from people with pink eye until they are no longer contagious.
