Opthal: Endophthalmitis: Free MSRA Podcast

🎧 MSRA Deep Dive: Endophthalmitis — A Sight-Threatening EmergencyToday’s episode covers Endophthalmitis — a rare but vision-threatening ophthalmic emergency. Whether you're prepping for the MSRA or need a fast, high-yield recap, we break it down clearly and clinically.🔍 Definition• Severe inflammation of intraocular tissues, especially the vitreous and retina• Almost always infectious⚠️ Emergency – Immediate treatment essential to prevent blindness💥 Mnemonic: PRIDE (Symptoms)• Pain – severe• Redness – conjunctival injection• Impaired vision – sudden drop• Discharge or lid swelling• Edema – corneal haze🧫 Causes & Types• Post-op (e.g. cataract surgery)• Trauma (open globe injury)• Endogenous (from systemic infection)• Bleb-related (e.g. after glaucoma surgery)• Injections (e.g. anti-VEGF)🔬 Pathogens• Bacterial: Staph, Strep, Bacillus cereus (rapid & aggressive)• Fungal: Candida (esp. immunocompromised)📌 Risk Factors• Recent surgery or trauma• Contact lens misuse• Immunosuppression (e.g. HIV, diabetes)• Corneal ulcers, systemic sepsis• Foreign body (esp. plant material)🧠 PathophysiologyPathogen breach → blood-ocular barrier disruption → immune response + toxins → damage to retina/vitreous → vision loss🩺 Differential Diagnosis• Uveitis• Optic neuritis• Retinal vein occlusion• Non-infectious causes💡 Not all red painful eyes are endophthalmitis — but always exclude it.📊 Epidemiology• Rare, but significant• Cataract post-op risk: 0.1–0.3%• More cases expected with higher surgical volumes🧪 Diagnosis• Slit-lamp + fundoscopy: hypopyon, vitreous haze• Vitreous tap / vitrectomy for culture + sensitivity• OCT for retinal architecture• Blood cultures if systemic signs• PCR / orbital imaging if unclear💉 Treatment (Urgent)• Intravitreal antibiotics: Vancomycin + ceftazidime• Antifungals (e.g. amphotericin B) if fungal cause• Systemic antibiotics in endogenous cases• Vitrectomy if:- Poor visual acuity- Dense opacities- No response to intravitreal therapy📈 Prognosis & ComplicationsDepends on:• Time to treatment• Causative organism• Severity at onsetRisks:• Retinal detachment• Cataract• Macular scarring• Secondary glaucoma• Vision loss or enucleation (in severe cases)🧠 MSRA Top Tips• Red eye + pain post-op? Think endophthalmitis• Hypopyon = key sign for bacterial infection• Candida → white retinal lesions + floaters• Sudden visual loss post-trauma?
