Conjunctivitis, also known as pink eye, is an inflammation of the conjunctiva that lines the eyelids and white part of the eye. It can be caused by bacterial or viral infections, allergies, or irritants. Common symptoms include redness, itching, watery discharge, light sensitivity, and blurred vision. Diagnosis involves examination of the eyes and potentially culture testing. Treatment focuses on relieving symptoms through rest, cool compresses, and antibiotic or antihistamine eye drops depending on the cause. Prevention involves hand washing and avoiding sharing personal items with infected individuals.

3. Introduction
3
The membrane that lines the eyelids
and the white part of the eye [sclera]
is called the conjunctiva. When the
small blood vessels in the
conjunctiva are inflamed, they swell
and become more visible causes the
eyes to appear reddish .that’s why
conjunctivitis is often called pink eye
or red eye.

4. DEFINITION
Inflammation of the transparent covering of the eye because of bacterial
or viral infection or allergic reaction. The eye appears swollen, and red
with itching sensation.

5. CAUSES
Bacterial infection: Caused by bacteria such as Staphylococcus aureus, Streptococcus pneumonia and Haemophilus influenza
•Viral infection: Generally caused by adenoviruses
•Allergic reaction to substances such as pollen, household dust, and pet dander
•Irritants such as pollutants, smoke, chlorine in swimming pools etc
Risk factors include:
•Contact with secretions from eye of an infected person - conjunctivitis is highly contagious
•Exposure to irritants
•Exposure to allergens
•Contact lens users - extended use of contact lens or unhygenic practices like not washing hands before taking off or inserting the
lens.

6. TYPES
Allergic
Bacterial
Viral
Chemical
neonatatal

7. SIGN /SYMPTOMS
The most common symptoms include:
•Red eye
•Irritation, itching, and a sensation of the presence of a foreign particle in the eye
•Watering eyes or discharge from eyes that is yellow or green in colour
•Severe discharge in the night that makes opening the eyes difficult in the morning
•Light sensitivity
•Eyelid edema (in severe cases)
•Blurred vision

8. DIAGNOSTIC EVALUATION
Common tests & procedures
Physical examination: The doctor uses bright light to evaluate external structures of the eye.
Slit lamp examination: The doctor views structures of the eye like conjunctiva and cornea under
magnification to rule out corneal involvement and prescence of any membrane, papillae or follicles on the
conjunctiva and determine the severity of the infection.
Bacteria culture test: Culture of the discharge from infected eyes is done in case of highly contagious or
risky cases.
Patch test: To identify the allergy causing substances, in case of allergic conjunctivitis.

9. TREATMENT
Most cases of conjunctivitis get better on their own without any treatment. Self-care practices can provide symptom relief.
Sometimes, medication may be required.
Medication
Antibiotic eye drops or ointments: To treat bacterial infections.
Chloramphenicol . Moxifloxacin/Ciprofloxacin
Antihistamine eye drops: Treats allergic conjunctivitis by reducing inflammation.
Olopatadine

10. PREVENTION
•Do not touch your eyes after touching any other objects or surfaces
without washing the hands.
•Do not share items such as makeup, pillows, or towels used by an
infected person. -Avoid sharing eye makeup and contact lenses with
anyone.

11. NURSING MANAGEMENT
•Check visual acuity
•Educate the patient on the disease
•Apply cool compress
•Administer medications as prescribed
•Encourage hand washing
•Use artificial tears if the eye is irritated
•Advise not to share personal care items
•Keep children at home until symptoms subside
•Wear sunglasses when going out
•If the discharge is purulent .

12. NURSING DIADNOSIS
Acute pain related to inflammation of conjunctiva.
Anxiety related to lack of knowledge about disease process .
Self care disturbance related to changes in the eyelids swelling
,edema.
Risk of injurey related to limits of vision.
