Conjunctivitis Flashcards
Pathophysiology of Allergic Conjunctivitis
Contact with allergen results in an allergic response (overreaction of the immune response). The mast cell and histamine mediators are the activated, resulting in inflammation
Pathophysiology of Bacteria Conjunctivitis
When bacteria comes in contact with the bulbar or palpebral conjunctiva, they are recognized as foreign antigens and an antigen-antibody immune reaction occurs, resulting in inflammation
Pathophysiology of Viral Conjunctivitis
When viruses comes in contact with the bulbar or palpebral conjunctiva, they are recognized as foreign antigens and an antigen-antibody immune reaction occurs, resulting in inflammation
Risk Factors for Allergic Conjunctivitis
(1) Family History
(2) History of asthma
(3) Allergic rhinitis
(4) Atopic Dermatitis
Risk Factors for Bacterial and Viral Conjunctivitis
(1) Age younger than 2 weeks
(2) Day Care
(3) Preschool or School attendance
(4) Viral Upper Respiratory Infections
(5) Pharyngitis
(6) Otitis Media
Sign/Symptoms of Allergic Conjunctivitis

(3) Itching
(4) Eyelid Edema
Signs/Symptoms of Bacterial Conjunctivitis
(1) Inflamed Conjunctivae
(2) Purulent, mucoid
(3) Mild Pain
(4) Occasional Eyelid Edema
Signs/Symptoms of Viral Conjunctivitis
(1) Inflamed Conjunctivae
(2) Watery, mucoid
(3) Lymphadenopathy, photophobia, tearing
(4) Eyelid Edema
Interventions for Allergic Conjunctivitis
(1) Eye drops with antihistamine or mast stabilizer drops
(2) Encourage not to rub/touch eyes
(3) Rinse child’s eyelids periodically with a clean washcloth and cool water
(4) When the child comes in from outdoors, wash the child’s face and hands

(3) Encourage not rub/touch eyes
(4) Do not share towels or washcloths
(5) Handwashing
(6) May return to school when mucopurulent drainage is no longer present (usually 24-48 hours of treatment with a topical antibiotic)
Interventions for Viral Conjunctivitis
(1) Warm compress
(2) Symptom Relief: antiherpetic agent if caused by herpes
(3) Handwashing
(4) May return to school when symptoms lessen
Nursing Assessment:
(1) Health History:
> Sign/Symptoms reported may include:
> Redness
> Edema
> Tearing
> Discharge
> Eye pain
> Itching of the eye
> Determine onset of symptoms and their progression and response to treatments used at home
> Assess risk factors
(2) Physical Examination
> Observe for eyelid swelling
> Inspect the conjunctiva for redness
> Note quantity, color and consistency of discharge
(3) Nursing Management:
> Alleviating Symptoms:
(1) Teach parents how to apply eye drops or ointment
(2) Warm compresses
(3) Encourage the child to avoid perennial allergens
> Preventing Infectious Spread
(1) Teach appropriate handwashing
(2) Discourage sharing towels and washcloths
(3) Bacterial- return to school 24-48 hours after treatment)
(4) Viral- return to school when symptom lessen
