 🎧MSRA Podcast:Episcleritis — More Than Just a Red EyeWelcome to the DeepDive! Today we’re exploring episcleritis,a condition that shows up regularly in exams like the MSRA and in real-world general practice. It’s common, oftenbenign, but crucial to distinguish from its deeper, more dangerous cousin — scleritis. 👁️What Is Episcleritis?A benign, self-limiting inflammation of the episclera, the thin tissue layer between theconjunctiva and sclera.Key featuresinclude:• Localized redness• Mild eye discomfort or grittiness• Often unilateral, but can be bilateral 🔑Core Features —Episcleritis vs. Scleritis:• Episcleritis = superficial, mild, mobilevessels, blanch with phenylephrine• Scleritis = deep, severe pain, fixed vessels, no blanching, risk of complications🔍Mnemonic to remember:Epi is easy, sclerais serious. 💡Types ofEpiscleritis:Simple – flat, diffuse redness (like a blush)Nodular – visible, raised nodule; often lasts longer and linked to systemic disease 🦠Causes andAssociations:• Idiopathic – ~70% of cases• Autoimmune diseases – e.g. rheumatoid arthritis, lupus, IBD, granulomatosis with polyangiitis• Infectious – herpes zoster/simplex, Lyme,syphilis, hepatitis B• Other – gout (hyperuricaemia), rosacea, thyroideye disease, chemical/foreign body triggers• Rare associations– e.g. T-cell leukemia, Wiskott-Aldrich syndrome, paraneoplastic syndromes 📊Epidemiology (UK):• Incidence: ~41 per 100,000 annually• Prevalence: ~53 per 100,000• Most common in 20–50 year-olds• Slight female predominance• Often recurrent, particularly with systemicinflammatory conditions 🧠Pathophysiology:• Immune-mediatedinflammation of superficial episcleral vessels• Causes vasodilation and leakage,producing redness and irritation 🩺DifferentialDiagnosis – Red Eye Causes to Consider:• Scleritis (deep, severe pain, doesn't blanch)• Conjunctivitis (discharge, crusting)• Uveitis (photophobia, blurred vision)• Contact lens-related injury• Posteriorscleritis (no redness, but deep pain and vision changes)• Orbitalcellulitis, optic neuritis, retinal detachment (if atypical) 🔬Diagnosis:• Clinical – basedon redness, vessel mobility, and pain level• Phenylephrine test – blanching suggestsepiscleritis• Slit lamp:superficial vessel dilation, nodule (if nodular type)• Blood tests onlyif recurrent, nodular, or systemic symptoms (RA, ANA, uric acid etc.) 💊Management (UKMSRA-aligned):• Lubricating drops – first-line for comfort• Cool compresses• Topical NSAIDs – e.g. ketorolac• Topical steroids – short course for more severecases (with IOP monitoring)• Oral NSAIDs – for nodular or persistentsymptoms• Refer to ophthalmology if:– Recurrent (>3episodes)– Nodular + systemicdisease– No improvement– Uncertaindiagnosis (rule out scleritis) 📈Prognosis:• Excellent – most resolve within 1–2 weeks• Complications are rare• Recurrencepossible, especially with underlying inflammatory conditions• Rare progressionto scleritis or scleral thinning if untreated 🧠Quick Summary — MSRAEssentials:• Episcleritis = benign, superficial, self-limiting• Rule out scleritis with pain level,phenylephrine blanching, and vessel mobility• Think systemic if recurrent or nodular• Treatment: lubricants → NSAIDs → short steroids• Prognosis: excellent, minimal complications 📚Episcleritis MSRARevision Resources:📝 Revision Notes:https://www.passthemsra.com/topic/episcleritis-revision-notes/🃏 Flashcards:https://www.passthemsra.com/topic/episcleritis-flashcards/📖 Accordion Q&A Notes:https://www.passthemsra.com/topic/episcleritis-accordion-qa-notes/🧠 Rapid Quiz:https://www.passthemsra.com/topic/episcleritis-rapid-quiz/ 🔗Explore more revisiontools:🌐https://www.passthemsra.com🌐https://www.freemsra.com#MSRA #Ophthalmology#Episcleritis #MSRAQuiz #MSRARevision #MSRAFlashcards #MSRAAccordions #RedEye#PhenylephrineTest #UKGuidelines #PassTheMSRA #GPRevision #EyeExam
