PHOMS can mimic various optic disc diseases, potentially leading to misdiagnosis in clinical settings. Understanding its pathogenesis and clinical signs is crucial for differentiating it from other conditions. This episode discusses the differential diagnoses and how to identify them through imaging techniques.
