EDME Eye Emergencies Part2

Eye Emergencies Part 2: The Red Eye & Acute Vision Loss | EDME Series Which red eye can blind? And why does painless vision loss deserve as much fear as the painful kind? Part 2 covers acute angle-closure glaucoma, keratitis and herpetic eye disease, giant cell arteritis, and central retinal artery occlusion, the "stroke of the eye". It ends with a close look at how the 2025–2026 thrombolysis trials have overtaken the textbooks. Based on the EDME teaching presentation by Dr. Nasser Hassan Abdalrady, Emergency Medicine Consultant & Educator. Grounded in Tintinalli's and Rosen's Emergency Medicine, with current international guidelines and trial evidence. ⏱ CHAPTERS 00:00 The red eye: harmless or blinding? 00:29 Acute angle-closure glaucoma 02:09 Contact lens keratitis & HSV: never start topical steroids 03:59 Sudden painless vision loss 04:36 Giant cell arteritis: don't wait for the biopsy 05:41 CRAO: the stroke of the eye 07:09 Thrombolysis for CRAO: the THEIA and TenCRAOS trials 10:29 Stroke pathway & work-up 11:02 Recap 11:59 Ocular POCUS & optic nerve sheath thresholds 13:40 Closing 🔑 KEY TAKEAWAYS Pain, photophobia and reduced vision are the red-eye red flags Never start topical steroids from the ED, and never patch a contact-lens eye Suspect GCA? Start steroids before results to protect the other eye Sudden painless monocular vision loss is a stroke: activate the stroke pathway Current RCT evidence does not support routine thrombolysis for CRAO ⏮ Watch Part 1 first: Triage & Ocular Trauma [Part 1 link] 📚 REFERENCES Tintinalli's Emergency Medicine, 9th ed.
