What does ophthalmology mean?
Ophthalmology is the branch of medicine devoted to the eye and vision. It covers the structure and function of the eye as well as the diagnosis and treatment of visual disorders, including diseases affecting the cornea, lens, retina, optic nerve, and related structures. The field overlaps with optometry, but ophthalmology is specifically a medical specialty whose practitioners are physicians and surgeons who can prescribe medication and perform surgery. The term is used formally in clinical practice, medical education, and research. In general writing, it may also serve as a concise name for the body of knowledge and expertise associated with eye care. Ophthalmologists work in areas such as cataract surgery, glaucoma management, retinal disease, paediatric ophthalmology, and corneal medicine. The word is especially useful when speaking about eye health as a whole because it identifies a broad medical discipline rather than a single disease or procedure.

Where does ophthalmology come from?
Ophthalmology combines Greek ophthalmos, meaning “eye,” with the Greek-derived suffix -logy, meaning “study of.” The compound entered English in the early 17th century as a name for the study of the eye. Its related vocabulary includes the adjective ophthalmic and the instrument and examination terms ophthalmoscope and ophthalmoscopy, all of which share the same Greek foundation.
