CDOS Certified Diagnostic Ophthalmic Sonographer Certification Exam

Certified Diagnostic Ophthalmic Sonographer (CDOS) Ultrasound physics fundamentals? particularly acoustic impedance and attenuation? aren’t optional prerequisites; they’re essential for interpreting A-scan and B-scan images correctly. Candidates entering the CDOS exam should already grasp ocular anatomy in detail, recognize pathological presentations like retinal detachments and posterior staphylomas, and understand immersion versus contact technique applications. Without solid grounding in these areas, test questions on image artifact recognition and measurement accuracy become significantly harder to navigate.
