Can a patient lose vision in just a few hours? With glaucoma, the answer is yes.
In this episode of The 2 AM Consult, Dr. Deer sits down with board-certified veterinary ophthalmologist Dr. Alex Sigmund (The Vet Eye Guy) to discuss one of the most time-sensitive ophthalmic emergencies encountered in general practice and the ER.
Together they cover:
- What glaucoma actually is—and why it's a true emergency
- Primary vs. secondary glaucoma
- Breed predispositions and clinical signs
- Tonometry tips and common diagnostic mistakes
- Emergency treatment protocols, including when to use dorzolamide, latanoprost, mannitol, and aqueocentesis
- Pain management and long-term monitoring
- When to refer to ophthalmology
- Surgical options and when enucleation is the best choice
Whether you're a GP veterinarian, ER clinician, intern, or student, this episode is packed with practical, evidence-based pearls you can apply the very next time a painful red eye walks through the door.
