A neurosurgeon is a surgeon who specializes in the brain and neurological system. They diagnose and treat disorders of the central and peripheral nervous system. They work closely with neurologists and other medical professionals to provide the best medical care possible to their patients. Some neurosurgeons also specialize in other areas or in specific health problems, diseases, or disorders.

Optometry is a medical profession that deals with the eyes and eye health. Optometrists can look at patients’ eyes to address abnormalities or irregularities as well as diagnose diseases of the eye. These doctors may also refer patients to surgeons who can correct eye problems. While optometrists do also focus on helping people find corrective lenses that can improve their vision, their focus extends far beyond glasses and contacts to include overall eye health, including management of eye diseases.
