OPHTHALMOLOGY (Gr. o^eaX/iOS, eye), the science of the anatomy, physiology and pathology of the eye (see Eve and Vision). From the same Greek word come numerous other derivatives: e.g. ophthalmia, the general name for conjunctival inflammations (see Eye diseases, under Eye) ; and the instruments ophthalmometer and ophthalmoscope (see Vision).
