Which professional would most likely use an ophthalmoscope?

The ophthalmologist is the most likely professional to use an ophthalmoscope because this instrument is specifically designed for examining the interior structures of the eye, including the retina, optic disc, and blood vessels. An ophthalmologist specializes in eye and vision care, making the use of this tool essential for diagnosing and monitoring various eye conditions, such as glaucoma, retinal diseases, and other ocular health issues.

While other professionals such as general practitioners and nurse practitioners might perform basic eye exams and assess vision, their training and scope of practice typically do not involve the detailed examination of the eye that an ophthalmoscope provides. Dentists usually focus on oral health and do not utilize this tool in their practice. Thus, the specialized training and focus of the ophthalmologist on eye health position them as the primary user of an ophthalmoscope.
