 👁️ Corneal Ulcers – High-Yield MSRA Deep Dive 👁️Welcome to today’sDeep Dive! We’re zooming in on a serious but surprisingly common eye emergency– corneal ulcers.📌 What is it?A corneal ulcer isan open sore on the cornea – the clear“windshield” at the front of your eye. Most commonly due to infection, it’s a true ophthalmic emergency that can lead to vision loss or even corneal perforation if left untreated. 🧪 Causes & Risk Factors:Infectious causes:  • Bacterial (e.g. Staph aureus, Pseudomonas)   • Viral (Herpes simplex, Varicella zoster)   • Fungal (Candida, Fusarium)   • Parasitic (Acanthamoeba – often linked to contact lenses + water)Other risk factors:  • Contact lens misuse   • Corneal trauma   • Dry eyes or blepharitis   • Immunosuppression   • Poor hygiene or water exposure🧠 Mnemonic for risk factors: C-L-E-P-SContact lensesLesions (trauma or surgery)Eye surface diseasePoor immunitySoil or swimming exposure 🔍 Symptoms – Look for “PRIDEFUL” signs:Painful red eyeRednessInfiltrate/white spotDischargeExcessive tearing (lacrimation)Foreign body sensationUlcer visible on examLight sensitivity (photophobia)📊 Common differentials:Corneal abrasionHerpetic or fungal keratitisConjunctivitisAnterior uveitisKeratoconjunctivitis 🛠️ Investigations:Slit-lamp exam: crucial for identifying the ulcer and corneal staining with fluoresceinCorneal scrapings/cultures: to identify the organism (especially in infective cases) 💊 Management:Urgent treatment neededIntensive topical antibiotics, antifungals, or antivirals based on causePain relief, sometimes a bandage contact lensHospital admission for severe cases or risk of perforationSurgery (e.g. corneal transplant) if structural damage or scarring occurs🎯 Prognosis:Good with early treatmentComplications: scarring, perforation, vision loss, secondary glaucoma 🧠 MSRA Exam Focus:Know key pathogens & risk factorsUnderstand classic features and urgent management stepsDifferentiate from anterior uveitis and conjunctivitisRemember: Prompt referral = preserved vision 📚 Useful Resources:• Revision notes → https://www.passthemsra.com/topic/corneal-ulcer-revision-notes/• Flashcards → https://www.passthemsra.com/topic/corneal-ulcer-flashcards/• Q&A accordion→ https://www.passthemsra.com/topic/corneal-ulcer-accordion-qa-notes/• Rapid quiz → https://www.passthemsra.com/topic/corneal-ulcer-rapid-quiz/• MCQ quiz → https://www.passthemsra.com/quizzes/corneal-ulcer/ 🧠 Final Message:Corneal ulcers areserious – pain, photophobia, and a white corneallesion = refer urgently.
