Certainly! Conjunctivitis, commonly known as pink eye, is an inflammation of the conjunctiva, which is the thin membrane covering the white part of the eye and the inner surface of the eyelids. Here’s a rundown of key information about it:

Causes

1. Viral Conjunctivitis: Often caused by adenoviruses. It’s highly contagious and typically accompanies cold symptoms.
2. Bacterial Conjunctivitis: Caused by bacteria such as Staphylococcus or Streptococcus. It may produce a yellow or green discharge.
3. Allergic Conjunctivitis: Triggered by allergens like pollen, dust, or pet dander. It often comes with itching and tearing.
4. Irritant Conjunctivitis: Results from exposure to irritants like smoke, chlorine, or chemicals.

Symptoms

• Redness in the eye or eyes
• Itching or burning sensation
• Discharge (which may be watery or thick and sticky)
• Tearing
• Swollen eyelids
• Sensitivity to light

Diagnosis

Diagnosis is usually based on a medical history and a physical examination of the eye. Sometimes, tests such as eye swabs or allergy tests may be conducted if the cause is unclear.

Treatment

• Viral Conjunctivitis: Usually resolves on its own within 1-2 weeks. Symptoms can be managed with warm compresses and artificial tears.
• Bacterial Conjunctivitis: Typically treated with antibiotic eye drops or ointments. It’s important to follow the prescribed treatment and complete the full course.
• Allergic Conjunctivitis: Managed with antihistamine eye drops and avoiding allergens. In severe cases, corticosteroid eye drops may be prescribed.
• Irritant Conjunctivitis: Rinsing the eyes with water and avoiding the irritant is usually sufficient.

Prevention

• Wash hands frequently and avoid touching the face.
• Use clean towels and washcloths.
• Avoid sharing personal items like eye makeup or contact lenses.
• If you wear contact lenses, follow proper hygiene practices and avoid wearing them if you have conjunctivitis.

When to See a Doctor

You should see a healthcare provider if:

• Symptoms do not improve with over-the-counter treatments.
• There is severe pain, vision changes, or light sensitivity.
• There is a lot of discharge, especially if it’s green or yellow.

Symptoms:

Common Symptoms:

• Redness: One or both eyes may appear red or pink.
• Itching: A common symptom, especially in allergic conjunctivitis.
• Burning Sensation: Feeling a burning or gritty sensation in the eyes.
• Discharge:
  • Viral: Usually clear or watery discharge.
  • Bacterial: Thick, yellow or green discharge that can cause the eyelids to stick together, especially in the morning.
  • Allergic: Watery or stringy discharge.
• Tearing: Increased tearing or watering of the eyes.
• Swollen Eyelids: The eyelids may be swollen and puffy.
• Sensitivity to Light: Discomfort or pain in bright light.
• Crusting: Discharge may form crusts on the eyelids and lashes, especially after sleeping.

Symptoms Specific to Each Type:

1. Viral Conjunctivitis: Often associated with symptoms of a cold, such as a runny nose or sore throat. It tends to start in one eye and can spread to the other.
2. Bacterial Conjunctivitis: May start in one eye and can spread to the other. The discharge is often thicker and may be yellow or green.
3. Allergic Conjunctivitis: Often occurs in both eyes and is accompanied by intense itching, redness, and tearing. It may also be associated with other allergic symptoms like sneezing or a runny nose.
4. Irritant Conjunctivitis: Usually affects both eyes and is caused by exposure to irritants like smoke or chemicals. Symptoms might include redness, discomfort, and tearing, which improve once the irritant is removed.

When to Seek Medical Attention:

• Severe Pain: Intense discomfort or pain in the eye.
• Vision Changes: Blurred or decreased vision.
• Sensitivity to Light: Increased sensitivity to light.
• Persistent Symptoms: Symptoms do not improve with over-the-counter treatments.

  • Warm Compresses: Applying a warm, damp cloth to the affected eye can help soothe irritation and reduce swelling.
  • Artificial Tears: Over-the-counter lubricating eye drops can help relieve dryness and discomfort.
  • Hygiene: Practicing good hygiene, such as washing hands frequently and avoiding touching the eyes, to prevent spreading the infection.

**2. Bacterial Conjunctivitis:

• Antibiotic Eye Drops/Ointments: Commonly prescribed antibiotics for bacterial conjunctivitis include:
  • Chloramphenicol: Often used in India for its effectiveness against a broad range of bacteria.
  • Ofloxacin or Ciprofloxacin: Fluoroquinolones that are also effective against bacterial infections.
  • Tobramycin or Neomycin: Sometimes used depending on the specific bacteria involved.
• Hygiene: Similar to viral conjunctivitis, maintaining good hygiene and avoiding sharing personal items is important.

**3. Allergic Conjunctivitis:

• Antihistamine Eye Drops: Over-the-counter drops containing antihistamines (e.g., ketotifen) can help relieve itching and redness.
• Decongestant Eye Drops: May be used to reduce redness.
• Avoid Allergens: Identifying and avoiding triggers such as pollen, dust, or pet dander.
• Cold Compresses: Applying cold compresses can help reduce itching and swelling.

Diagnosing conjunctivitis:

*1. Medical History:

• Symptom Review: Discuss the onset, duration, and nature of symptoms such as redness, itching, discharge, and any accompanying symptoms like fever or cold.
• Exposure History: Provide information on potential exposure to irritants, allergens, or infectious agents.
• Contact Lens Use: Mention if you use contact lenses and the cleaning regimen followed.
• Allergic Reactions: Inform the doctor about any known allergies or recent allergen exposure.

**2. Physical Examination:

• Visual Inspection: The doctor will examine the eyes for signs of redness, swelling, discharge, and any other visible symptoms.
• Eye Examination: Using a slit lamp or ophthalmoscope, the doctor will assess the conjunctiva, cornea, and other parts of the eye.
• Pupil Response: Checking how the pupils react to light and movement to rule out other eye conditions.

**3. Diagnostic Tests:

• Conjunctival Swab: A sample of discharge from the eye may be collected and analyzed to identify bacterial or viral pathogens. This can help in diagnosing bacterial conjunctivitis or viral strains.
• Allergy Testing: If allergic conjunctivitis is suspected, tests for specific allergens might be conducted.
• Tear Production Tests: Tests like the Schirmer test may be performed to assess tear production if dry eyes are suspected.

**4. Differential Diagnosis:

The healthcare provider will also consider other conditions that might mimic conjunctivitis symptoms, such as:

• Blepharitis: Inflammation of the eyelid margins.
• Keratitis: Inflammation of the cornea.
• Uveitis: Inflammation of the middle layer of the eye.
• Scleritis: Inflammation of the sclera (the white part of the eye).

**5. Referral to a Specialist:

If the diagnosis is unclear or if the conjunctivitis is severe or persistent, the doctor might refer you to an ophthalmologist for further evaluation and treatment.
