ICO Visual Sciences · Put your knowledge to work in context.

The ICO Visual Sciences Examination is a standardized, multiple-choice test of the basic and clinical science underpinning ophthalmology, administered within the International Council of Ophthalmology's assessment programme. It is aimed at trainees who have completed foundational ophthalmology training and want an external, internationally benchmarked check of their grasp of visual science before or alongside clinical specialty examinations. It is also used by residency programmes and national boards as an external reference point. The exam samples ten domains: optics and refraction, physiological optics and visual perception, anatomy and histology, ocular physiology and biochemistry, retina and visual neuroscience, motility and binocular vision, pharmacology and toxicology, microbiology and immunology, pathology and genetics, and clinical visual sciences and diagnostic testing. The ICO Visual Sciences case studies are 5 cases and about 3,018 words.
