Which of the following are types of ophthalmic imaging?

The correct answer identifies types of ophthalmic imaging specific to the eye and visual system. Ophthalmic imaging is focused on capturing detailed images for diagnosing diseases and conditions affecting the eye.

The methods identified—external imaging, slit lamp examination, and fundus photography—are all designed to visualize different parts of the eye. External imaging involves examining the outer structures of the eye, slit lamp biomicroscopy allows for a detailed view of the anterior segment, and fundus photography captures images of the retina and optic nerve at the back of the eye.

Other choices include imaging techniques that may be used in medical diagnostics but do not specifically cater to ophthalmic purposes. For example, CT scans and MRIs are more general imaging technologies used for various parts of the body and not tailored to eye examination. Likewise, ultrasound, X-ray, and fluoroscopy are primarily used in different medical fields and do not specialize in eye structure imaging.

The final choice, which mentions optical coherence tomography, fundus photography, and wavefront sensing, also includes valid ophthalmic imaging techniques. Optical coherence tomography is a non-invasive imaging technique that provides high-resolution images of the retinal layers, while wavefront sensing helps measure how light waves travel through the eye. This choice is accurate but
