Certified Diagnostic Ophthalmic Sonographer (CDOS) CDOS certification distinguishes itself by focusing exclusively on ocular ultrasound imaging, whereas general ultrasound sonographer credentials span multiple body systems. This specialization means deeper training in A-scan and B-scan interpretation for retinal detachment, posterior segment pathology, and biometry? skills that generalist sonographers rarely develop to the same clinical depth or speed.
