OCT-C case studies
OCT-C · Put your knowledge to work in context.
The OCT-C (Certified Optical Coherence Tomography Technologist) credential, administered by the Ophthalmic Photographers' Society, recognizes technologists who can independently acquire, evaluate, and troubleshoot OCT images across posterior and anterior segment applications. It is aimed at ophthalmic photographers, imaging technicians, and ophthalmic assistants whose daily work includes OCT capture and image review, and who want a formal demonstration of competence beyond on-the-job training. The OCT-C case studies are 5 cases and about 2,981 words.
