What is Conjunctivitis?
Definition of conjunctivitis
Conjunctivitis, commonly known as pink eye, is an inflammation of the conjunctiva, which is the clear tissue that covers the front surface of the eye and lines the inside of the eyelids. This condition can affect people of all ages and is highly contagious. Conjunctivitis can occur due to various factors, such as viral or bacterial infections, allergies, or exposure to irritants or chemicals.
Common causes of conjunctivitis
Conjunctivitis can be caused by different factors, each requiring specific treatment. The most common causes are:
Viral conjunctivitis: Caused by a virus, often associated with the common cold. This type of conjunctivitis is highly contagious and can spread through respiratory droplets or direct contact with an infected person.
Bacterial conjunctivitis: Caused by bacteria, such as Staphylococcus aureus or Streptococcus pneumoniae. Bacterial conjunctivitis can be spread through direct contact with discharge from an infected eye or by touching contaminated surfaces.
Allergic conjunctivitis: Caused by an allergic reaction to substances such as pollen, dust mites, or pet dander. Allergic conjunctivitis is not contagious and often occurs seasonally.
Giant papillary conjunctivitis: This type of conjunctivitis is usually associated with wearing contact lenses or ocular prosthetics. It is characterized by the formation of large bumps on the underside of the eyelids.
Chemical conjunctivitis: Caused by exposure to irritating chemicals, such as household cleaners, smoke, or swimming pool chemicals. This type of conjunctivitis is typically not contagious.
Irritant conjunctivitis: Caused by mechanical irritation, such as rubbing the eyes excessively, makeup, or foreign bodies. Irritant conjunctivitis is not contagious.
Symptoms of conjunctivitis
Regardless of the cause, conjunctivitis can present similar symptoms, including:
- Redness and swelling of the eye or eyelid
- Itchy and watery eyes
- Gritty or sandy feeling in the eye
- Discharge, which can be watery (viral), thick and yellowish-green (bacterial), or stringy and clear (allergic)
- Sensitivity to light
- Blurred vision
- Crusty eyelids upon waking up
If you experience any of these symptoms, it is important to seek medical advice to determine the specific cause and receive appropriate treatment.
Types of Conjunctivitis
Viral conjunctivitis
Viral conjunctivitis is the most common type and is usually caused by adenoviruses. It is highly contagious and can easily spread through close contact with an infected person or contaminated surfaces. The symptoms typically include redness, watery discharge, and itching. Viral conjunctivitis usually resolves on its own within one to two weeks, and treatment is aimed at relieving symptoms.
Bacterial conjunctivitis
Bacterial conjunctivitis is caused by bacterial infection and is often accompanied by a thick yellowish or greenish discharge. It can be spread through direct contact with an infected person or contaminated objects. Antibiotic eye drops or ointments are usually prescribed to treat bacterial conjunctivitis. It is important to complete the full course of antibiotics as prescribed by a healthcare professional.
Allergic conjunctivitis
Allergic conjunctivitis is triggered by an allergic reaction to substances such as pollen, dust mites, or pet dander. The symptoms include redness, itching, and watery discharge. Avoiding the allergen is the best way to prevent allergic conjunctivitis. Over-the-counter antihistamine eye drops may provide relief, but severe cases may require prescription medications or immunotherapy.
Giant papillary conjunctivitis
Giant papillary conjunctivitis is associated with the prolonged use of contact lenses, ocular prosthetics, or stitches. It is characterized by the formation of large bumps on the inside of the upper eyelids. Treatment involves discontinuing the use of the offending device, prescribing medicated eye drops, and ensuring proper hygiene of contact lenses.
Chemical conjunctivitis
Chemical conjunctivitis occurs when the eyes come into contact with irritating substances, such as household cleaners, smoke, or chemicals. It is important to flush the eyes thoroughly with clean water in case of chemical exposure. If symptoms persist or worsen, medical attention should be sought.
Irritant conjunctivitis
Irritant conjunctivitis is caused by mechanical irritation, such as excessive rubbing of the eyes, foreign bodies, or certain cosmetic products. Avoiding the irritant and practicing good eye hygiene will typically resolve the condition. If symptoms persist, consult a healthcare professional for further evaluation.
Diagnosing Conjunctivitis
Physical examination
A healthcare professional can diagnose conjunctivitis by performing a physical examination of the eyes and eyelids. They will look for signs of redness, swelling, discharge, or any abnormalities.
Eye swab test
In some cases, an eye swab test may be performed to determine the cause of conjunctivitis. The swab is gently rubbed on the inside of the lower eyelid to collect a sample, which is then sent to a laboratory for analysis.
Allergy testing
If allergic conjunctivitis is suspected, allergy testing may be recommended to identify specific allergens causing the reaction. This can help with developing an appropriate treatment plan or avoiding triggering substances.
Conjunctival biopsy
In rare cases where the cause of conjunctivitis is unclear, a conjunctival biopsy may be performed. A small sample of tissue is taken from the conjunctiva and examined under a microscope to identify any underlying conditions.
Preventing Conjunctivitis
Practicing good hygiene
Good hygiene is essential in preventing the spread of conjunctivitis. Wash your hands frequently with soap and water, especially after touching your eyes or coming into contact with someone who has conjunctivitis. Avoid touching your eyes unnecessarily.
Avoiding touching the eyes
Avoid rubbing or touching your eyes, as this can introduce bacteria or irritants that may lead to conjunctivitis. If you must touch your eye, ensure your hands are clean.
Using clean contact lenses
If you wear contact lenses, it is crucial to follow proper hygiene practices. Clean and disinfect your lenses regularly, and avoid wearing them while you have conjunctivitis. Replace disposable lenses as recommended.
Washing hands frequently
Washing your hands regularly helps prevent the spread of conjunctivitis and other infections. Use soap and warm water, and scrub for at least 20 seconds.
Treatment Options
Antibiotics for bacterial conjunctivitis
If bacterial conjunctivitis is diagnosed, your healthcare professional may prescribe antibiotic eye drops or ointments to treat the infection. It is important to use the medication as prescribed, even if symptoms improve, to ensure complete eradication of the bacteria.
Antiviral medications for viral conjunctivitis
Antiviral medications are sometimes prescribed to treat severe cases of viral conjunctivitis caused by certain viruses, such as herpes simplex. However, most cases of viral conjunctivitis resolve on their own, and treatment is aimed at relieving symptoms.
Eye drops and ointments
Eye drops and ointments can provide relief from symptoms such as redness, itching, and dryness associated with conjunctivitis. These may contain antihistamines, decongestants, or lubricants, depending on the type and severity of the condition.
Cold compresses
Applying cold compresses can help reduce swelling and soothe the eyes. Use a clean washcloth or ice pack wrapped in a thin cloth and apply gently to the closed eyelids for a few minutes at a time.
Artificial tears
Artificial tears can provide temporary relief from dryness and irritation associated with conjunctivitis. These lubricating eye drops can be used as needed throughout the day.
Steroid eye drops
In severe cases of conjunctivitis, prescription steroid eye drops may be used to reduce inflammation and relieve symptoms. These should only be used under the guidance of a healthcare professional.
Nonsteroidal anti-inflammatory drugs (NSAIDs)
Nonsteroidal anti-inflammatory drugs can help reduce inflammation and alleviate symptoms. These are available in both prescription and over-the-counter forms and should be used as directed by a healthcare professional.
Home Remedies
Applying warm compresses
Warm compresses can help soothe tired eyes and relieve mild discomfort associated with conjunctivitis. Use a clean washcloth soaked in warm water and gently place it over closed eyelids for a few minutes at a time.
