Conjunctivitis (pink eye) – ED discharge instructions
💡 What You Need to Know
- Understanding Conjunctivitis: Often referred to as 'pink eye,' it is an inflammation of the conjunctiva, the clear membrane lining the eyelid and covering the white part of the eye.
- Common Causes: It can be caused by viruses (most common), bacteria, or allergens. Viral and bacterial forms are highly contagious.
- Key Symptoms: Characterized by redness, itching, tearing, discharge, and a gritty sensation in the affected eye(s).
- Contagion Period: Viral and bacterial conjunctivitis are contagious as long as symptoms are present, and sometimes even before symptoms appear.
🤒 Associated Symptoms
- Ocular Redness: Visible redness in one or both eyes, often starting in one eye and spreading to the other.
- Discharge: Watery discharge (common in viral/allergic) or thick, purulent discharge (common in bacterial) that may cause eyelids to stick together, especially upon waking.
- Itching/Burning: A persistent sensation of itching or burning in the eyes.
- Gritty Sensation: Feeling as if there is sand or a foreign body in the eye.
- Eyelid Swelling: Mild to moderate swelling of the eyelids.
- Photophobia: Increased sensitivity to light.
- Tearing: Excessive tearing from the affected eye(s).
🛡 Crucial Precautions
- Strict Hand Hygiene: Wash hands thoroughly with soap and water for at least 20 seconds, especially after touching your eyes or applying medication.
- Avoid Eye Contact: Refrain from touching, rubbing, or scratching the affected eye(s) to prevent irritation and spread of infection.
- No Sharing Policy: Do not share towels, pillowcases, eye drops, makeup, or any personal items that come into contact with the eyes.
- Contact Lens Discontinuation: Discontinue wearing contact lenses immediately. Discard current lenses and cases, and do not resume wear until symptoms have fully resolved and for at least 24-48 hours after stopping medication.
- Work/School Exclusion: Stay home from work, school, or daycare until symptoms significantly improve or for at least 24-48 hours after starting antibiotic eye drops for bacterial conjunctivitis.
- Cleanliness of Environment: Regularly clean and disinfect surfaces that may have come into contact with contaminated hands or secretions.
🍽 Dietary Directions & Restrictions
- Hydration Support: Maintain adequate fluid intake to support overall systemic health and immune response during an infection.
- Avoid Irritant Exposure: While not directly dietary, minimize exposure to environmental irritants like smoke or strong fumes that can exacerbate eye discomfort.
⚠️ Attendant Guidelines
- When to Seek Re-evaluation: Return to the Emergency Department or seek urgent medical attention if you experience worsening eye pain, significant vision changes (blurriness, loss of vision), severe photophobia, intense eyelid swelling, fever, or if symptoms do not improve within 2-3 days of starting treatment.
- Medication Adherence: Administer prescribed eye drops or ointment exactly as directed by your healthcare provider, completing the full course even if symptoms improve.
- Caregiver Hygiene: Any individual assisting with eye drop administration must practice meticulous hand hygiene before and after contact with the patient's eyes or medication.
- Avoid Self-Medication: Do not use leftover eye drops from previous infections or share prescribed medications with others.
🩺 Physician's Perspective
- Clinical Diagnosis: Conjunctivitis is primarily a clinical diagnosis, often not requiring laboratory testing unless severe, recurrent, or atypical.
- Etiology-Specific Treatment: Treatment strategies are tailored to the underlying cause; bacterial infections typically require topical antibiotics, while viral conjunctivitis is usually self-limiting and managed with supportive care. Allergic conjunctivitis responds to antihistamines.
- Infection Control Imperative: Emphasize the critical importance of strict hygiene measures to prevent the spread of highly contagious forms of conjunctivitis within households and communities.
- Follow-up Recommendations: Advise follow-up with a primary care provider or ophthalmologist if symptoms persist, worsen, or if there are concerns about vision.
🎓 Academic & Nursing Corner
- Differential Diagnosis Considerations: Key differentials include viral (e.g., adenovirus), bacterial (e.g., S. aureus, S. pneumoniae), allergic, chemical irritation, and less commonly, gonococcal or chlamydial conjunctivitis.
- Patient Education Priority: Nurses play a vital role in educating patients and families on proper hand hygiene, medication administration techniques, contact lens care, and recognizing signs for re-evaluation.
- Infection Control Protocols: Implement contact precautions in clinical settings for patients with suspected infectious conjunctivitis to prevent nosocomial transmission.
- Medication Administration Technique: Instruct patients on correct eye drop/ointment application, including pulling down the lower eyelid, applying the medication into the conjunctival sac, and avoiding touching the dropper tip to the eye.
🔬 Clinical Reference Index
- ICD-10 Codes: H10.0 (Mucopurulent conjunctivitis), H10.1 (Acute atopic conjunctivitis), H10.2 (Other acute serous conjunctivitis), H10.3 (Acute unspecified conjunctivitis).
- Common Pathogens: Viral: Adenovirus (most common); Bacterial: Staphylococcus aureus, Streptococcus pneumoniae, Haemophilus influenzae; Allergic: Pollen, dust mites, animal dander.
- Pharmacological Interventions: Topical antibiotics (e.g., erythromycin, polymyxin B/trimethoprim, fluoroquinolones), topical antihistamines/mast cell stabilizers (e.g., olopatadine), artificial tears for symptomatic relief.
- Potential Complications: Keratitis, corneal ulceration (rare but serious, especially with specific bacterial strains), chronic conjunctivitis, spread of infection to other ocular structures.
