🎧Deep Dive: Keratitis— Don’t Miss the Red, Painful EyeLet’sget laser-focused 🔬. If you’re revising for the MSRA or just want to truly understand whatkeratitis is (and why it's urgent), this is your express pass to mastering theessentials. 👁️What is Keratitis?It’sinflammation of the cornea — the clear, front part of your eye. And when it’sinfectious, it’s a genuine sight-threatening emergency ⚠️.Unlike conjunctivitis, this one can scar or even perforate the eye if not treated fast. 🧫Causes:Splitinto infectious vsnon-infectious ⬇️🦠Infectious• Bacterial: Staphaureus, Pseudomonas (esp. incontact lens wearers)• Viral: Herpes simplex• Fungal: Fusarium,Aspergillus• Parasitic: Acanthamoeba(linked to tap water + contact lenses)🌬️Non-infectious• Photokeratitis (UVexposure – skiing, welding)• Exposure keratitis(eyelids don’t close)• CLARE (ContactLens Acute Red Eye – sterile)• Dry eye, trauma,autoimmune inflammation ⚠️Major Risk Factors👁️ Wearing contact lenses — especially poor hygiene,sleeping in them, or water exposure🧼 Dirty hands, old lenses, tap water rinsing💥 Eye trauma🧬 Immunosuppression💧 Dry eyes💼 High-risk jobs (e.g. welders, lab workers)💡Mnemonic:“Painful Red Eye? Think 4PAD.”4PAD = Foreignbody sensation, Pain, Redness, Photophobia, Discharge 🔍Diagnosis🔎Slit lamp exam — look for opacity, infiltrates, ulcer🧪Corneal scraping +culture — for bacteria, fungi🧬PCR — useful for viruses, Acanthamoeba🧫Fluorescein staining — to reveal ulcers📷OCT or confocal microscopy— advanced cases 💊Management🎯 Depends on the cause:🦠Infectious• Topicalantibiotics (e.g. fluoroquinolones)• Antivirals (e.g.acyclovir for HSV)• Antifungals (e.g.natamycin)• Oral or IV medsfor severe cases🧘Non-infectious• Lubricating drops• Topical steroids(specialist use only)• Treat underlyingcause (dry eye, autoimmune)🆘Key Rule for MSRA:If a contact lens wearer presents with a painful red eye — assume microbial keratitis until proven otherwise.🛑 Stop lens use💉 Start broad-spectrum antibiotic drops📞 Urgent same-day ophthalmology referral💡Mnemonic:“Red, Painful, No Contacts Now” = Stop lenses,Treat immediately, Refer fast. 📉Complications❌ Corneal scarring (→ permanent vision loss)❌ Corneal perforation❌ Secondary endophthalmitis❌ May need corneal transplant if severe💡 Prognosis: GOOD if treated early. BAD if delayed. 🧠Summary Recap• Keratitis =corneal inflammation (infectious or not)• Risk ↑ withcontact lenses, trauma, poor hygiene• Red, painful,photophobic eye = RED FLAG• Treat underlyingcause• Urgent referral ifinfection suspected 🧠 Ready to reinforce your learning?📚 Keratitis Revision Notes:https://www.passthemsra.com/topic/keratitis-revision-notes/🃏 Flashcards:https://www.passthemsra.com/topic/keratitis-flashcards/📂 Accordion Q&A Notes:https://www.passthemsra.com/topic/keratitis-accordion-qa-notes/🧪 Rapid Quiz:https://www.passthemsra.com/topic/keratitis-rapid-quiz/🎯 Practice Questions:https://www.passthemsra.com/quizzes/keratitis/ 🌐 For full revision support:https://www.passthemsra.com🎁 Free learning tools:https://www.freemrsra.com Thanksfor tuning into this DeepDive on Keratitis — because visionmatters, and knowledge saves sight.
