EP 450: Iris Atrophy in Cats and Dogs – Clinical Signs, Causes & Ophthalmic Diagnosis

Welcome to Episode 450 of the Pet Care Partners Podcast, where we spotlight iris atrophy—a subtle yet clinically important ophthalmic finding in feline and canine patients. This episode is essential for veterinary students, general practitioners, and ophthalmology-focused clinicians looking to sharpen their recognition and understanding of this age-related or pathologic change. We’ll break down how to distinguish normal aging from neurologic or inflammatory causes, explore diagnostic methods, and discuss why iris atrophy can signal underlying disease processes that warrant further investigation. 🧠 In This Episode, You’ll Learn: 👁️ What is Iris Atrophy? • Thinning or loss of the iris stroma • Causes: senile degeneration, uveitis, glaucoma, chronic miosis, or trauma 🧪 How to Diagnose: • Slit-lamp biomicroscopy and direct ophthalmoscopy • Look for irregular pupil margins, transillumination defects, and poor pupillary light response (PLR) • Differentiation from iris hypoplasia or coloboma 🐕 Species and Breed Predispositions: • Common in geriatric small breed dogs (e.g., Poodles, Chihuahuas) • Less common but clinically relevant in cats ⚠️ When Iris Atrophy Matters: • When linked with secondary glaucoma • As an indicator of chronic anterior uveitis • As a differential when evaluating anisocoria 💡 Clinical Takeaways: • Often incidental but can indicate a broader systemic or ocular issue • Important in surgical planning (e.g., intraocular pressure monitoring) • A good opportunity for client education during senior wellness exams 🎯 Who Should Watch This: ✅ Veterinary students preparing for NAVLE or clinics ✅ GPs performing routine eye exams or neuro checks ✅ Vet techs learning ophthalmic observation skills ✅ Veterinary ophthalmology residents and interns ✅ Educators covering common but overlooked ocular conditions #IrisAtrophy #VeterinaryOphthalmology #VetPodcast #PetCarePartners #VeterinaryStudents #DVMlife #VetEducation #FelineOphthalmology #CanineOphthalmology #EyeExam #VeterinaryMedicine #OphthalmicDiagnosis #NAVLEprep #VeterinaryTraining #VetOphtho #SmallAnimalPractice #ClinicalSigns #Anisocoria #GeriatricPets #PupilAbnormalities #OcularHealth #VetTechLife #VetOphthalmologist #DogEyeCare #CatEyeHealth
