Ophthalmology is the branch of medicine which deals with the anatomy, physiology and diseases of the eye. The term ophthalmologist refers to a specialist in medical and surgical eye problems.Since ophthalmologists perform operations on eyes, they are considered to be both surgical and medical specialists.
The word ophthalmology comes from the Greek roots ophthalmos meaning eye and logos meaning word, thought, or discourse; ophthalmology literally means "the science of eyes". "Opthomology" is a common mis-hearing or mis-remembering of the term. As a discipline, it applies to animal eyes also, since the differences from human practice are surprisingly minor and are related mainly to differences in anatomy or prevalence, not differences in disease processes.
