Eye Infections | Podcast

Premium Member Resources: https://ninjanerd.org Ninja Nerds! In this episode of the Ninja Nerd Podcast, Zach and Rob walk you through a systematic, case-based approach to eye infections that show up everywhere, on exams, in urgent care, and in the middle of the night in the ED. Red eyes, swollen lids, scary diagnoses, and the big question every clinician has to answer fast, is this safe to manage outpatient, or is this a sight or life-threatening emergency? We start with the most common scenario, a red eye with discharge but normal vision, no photophobia, and no pain with eye movement. Using a 23 year old with morning crusting and purulent discharge, we break down how to quickly rule out red flag findings, localize the anatomy, and distinguish bacterial conjunctivitis from viral conjunctivitis and from lid and lacrimal infections. Along the way, we hit high-yield organisms and treatments, including staphylococcal conjunctivitis in adults, streptococcal pneumonia and Haemophilus influenzae in kids, and why contact lens wearers immediately raise concern for Pseudomonas. We also cover viral conjunctivitis from adenovirus, and how exam findings like watery discharge, follicles, and preauricular lymphadenopathy change management to supportive care only. Then we up the stakes with infections that can destroy the cornea fast. A contact lens wearer with severe pain, photophobia, decreased vision, and a hazy cornea becomes the perfect setup to review bacterial keratitis, corneal ulcers, hypopyon, and why you remove the lenses, avoid patching, and treat aggressively with topical fluoroquinolones with urgent ophthalmology involvement. We follow that with classic herpes keratitis and zoster ophthalmicus. If you have a dendritic lesion with terminal bulbs and decreased corneal sensation, you will never forget HSV, and you will never forget the trap of steroid monotherapy. We also review VZV clues like a V1 rash and Hutchinson sign with pseudodendrites, and why systemic antivirals matter. Next, we tackle one of the most high-yield differentials in pediatrics and emergency medicine, the swollen eyelid. Using a febrile child with sinus symptoms, painful and limited extraocular movements, proptosis, and decreased visual acuity, we show you how to separate preseptal cellulitis from orbital cellulitis using orbital red flags, and why orbital cellulitis demands imaging of the orbits and sinuses plus IV antibiotics that cover MRSA, sinus flora, and anaerobes. We also cover the nightmare complication, cavernous sinus thrombosis, including the classic progression to bilateral venous congestion and multiple cranial nerve palsies, and the treatment approach with broad IV antibiotics and anticoagulation. Finally, we close with a true ophthalmologic emergency after intraocular surgery. A patient with severe deep eye pain, floaters, loss of red reflex, hypopyon, and dramatic vision loss after cataract surgery sets up the discussion of endophthalmitis, the typical organisms like coagulase negative Staph, the key diagnostic steps including slit lamp, fundoscopy, and ocular ultrasound, and why intravitreal antibiotics and sometimes vitrectomy are time sensitive to preserve vision and prevent loss of the globe.
