PEDI | Sensory (Eyes & Ears)

• Visual Development: Binocular vision (using both eyes together) is not fully achieved until age 5. Disorders like strabismus (misalignment) must be corrected early to prevent amblyopia (lazy eye), which can cause permanent vision loss if the brain "turns off" the weaker eye.High-Yield Eye Disorders1. Conjunctivitis ("Pink Eye") Differentiation is key for treatment:• Bacterial: Purulent (pus-like) discharge, mild pain, often unilateral. Tx: Antibiotic drops/ointment.• Viral: Watery discharge, lymphadenopathy, tearing. Tx: Symptom relief only.• Allergic: Itching is the hallmark symptom, watery/stringy discharge. Tx: Antihistamines.• Nursing Priority: Infection control. Viral/bacterial forms are highly contagious. Isolate for 24 hours after starting antibiotics; discourage towel sharing.2. Structural & Functional Issues• Strabismus (Cross-eye): Normal in young infants but pathological if persistent. Treatment is critical to preserve vision.• Amblyopia: The brain suppresses the image from the "bad" eye. Intervention: Patch the healthy eye for several hours daily to force the weaker eye to work.• Retinopathy of Prematurity (ROP): Rapid growth of retinal blood vessels in preemies. Risk Factors: Low birth weight, early gestation, sepsis, and high/prolonged oxygen therapy.3. Trauma• Corneal Abrasions: Painful scratches. Do not patch the eye (increases infection risk).• Hyphema/Black Eye: Apply ice packs for 20 minutes on/off.• Emergency: Fixed/dilated pupils or objects penetrating the globe require immediate referral to ophthalmology.High-Yield Ear Disorders1. Acute Otitis Media (AOM)• Signs: Rapid onset, ear pain (otalgia), bulging/red tympanic membrane, fever, pulling at ears.• Management: "Watchful waiting" for 48-72 hours is common for older children to avoid overuse of antibiotics. If bacterial, antibiotics are prescribed. Pain management (analgesics) is a priority.2. Otitis Media with Effusion (OME)• Signs: Fluid in the middle ear without acute infection signs. The membrane looks dull, opaque, or gray with visible fluid levels.• Risk: Can persist for months, causing conductive hearing loss and speech delay.• Intervention: Pressure-equalizing (PE) tubes are surgically inserted for chronic cases to drain fluid.3. Otitis Externa ("Swimmer's Ear")• Signs: Infection of the ear canal. Hallmark sign is significant pain when pressure is applied to the tragus.• Tx: Antibiotic/antifungal ear drops. Wick insertion may be needed if swelling is severe.Key Nursing Interventions & Assessments• Assessment Cues: ◦ Vision: Infants should "fix and follow" objects. A dull, vacant stare or lack of eye contact is a red flag for visual impairment. ◦ Hearing: Lack of startle reflex to loud noises or failure to babble by 6 months indicates potential hearing loss.• Post-Op Care: ◦ Eye Surgery (Cataracts/Strabismus): Use elbow restraints to prevent the child from rubbing the operative site. Protect the site with patching.
