👁️Ectropion – When theLid Turns OutWelcome to thisquick, high-yield deep dive on ectropion,a common but important eyelid condition—especially in older adults. We're hereto clarify what it is, why it happens, how to spot it, and what to do about it. 🔍Definition:Ectropion is the outward turning of the lower eyelid, causingthe inner surface (conjunctiva) to be exposed. This disrupts normal teardrainage, leaving the eye dry, watery, and irritated. 🧠Causes – 5 MainTypes:Involutional – most common (age-related laxity)Paralytic – e.g., facial nerve palsyCicatricial – scarring pulls the lid outMechanical – mass or tumour pushes lid outwardCongenital – present at birth (rare)📌Mnemonic: OLD SICK FACEOld age, Laceration/trauma,Disease (e.g., skin),Surgery history, Innervationproblems, Congenital, Known lid laxity 😣Symptoms:Watery eyes (epiphora)RednessIrritation or gritty sensationSensitivity to lightDryness due to poor tear film contactExposure keratopathy in severe cases 🔎Clinical Signs:Visible sagging of lower eyelidRed conjunctiva exposedMalpositioned puncta (tear drainage holes) 🩺Diagnosis:Primarily clinical. Look for:Lid laxityPuncta displacementFluorescein staining (if corneal damage suspected) No imaging is usually required unless a mass is suspected. 🧬Risk Factors:Advanced ageFacial nerve palsyHistory of eyelid surgery or traumaSkin disorders, e.g., eczema or dermatitisChronic eye inflammation 💡Pathophysiology:The eyelid turnsoutward → puncta no longer drain tears → overflow (epiphora) + cornea exposed →dryness & irritation → long-term risk of ulceration. 🔄Differentials toKnow:Entropion – inward turning of eyelidTrichiasis – inward-growing lashesSevere blepharitisParalytic lid malposition (requires separate consideration) 💊Management:▶️Mild cases:Lubricating dropsNight-time eye ointmentsEyelid taping (temporary)▶️Persistent/moderateto severe:Surgical correction is definitive (e.g., lateral tarsal strip)Aim: restore lid tone and alignment▶️Paralytic causes:Address facial nerve palsyConsider gold weight implants or tarsorrhaphy in some cases 📈Prognosis:Excellent with surgery – high success, low recurrenceIf left untreated, complications can include:   • Exposure keratopathy  • Corneal ulcers/scarring  • Chronic conjunctivitis  • Reduced visual acuity 📚Useful Resources• Revision Notes → https://www.passthemsra.com/topic/ectropion-revision-notes/• Flashcards → https://www.passthemsra.com/topic/ectropion-flashcards/• Accordion Q&A→ https://www.passthemsra.com/topic/ectropion-accordion-qa-notes/• Rapid Quiz → https://www.passthemsra.com/topic/ectropion-rapid-quiz/• Quiz Link → https://www.passthemsra.com/quizzes/ectropion/ 🎯Key MSRA Takeaway:Ectropion = outward-turning lid, common in older adults, causes epiphora and exposure issues,often treated with surgery. Know thetypes, causes, and complications. 💭Final Thought:As we age, eyelidstructure changes can impact vision and comfort. Recognising ectropionearly—and knowing when to refer—can prevent serious complications.
