Etymology
Etymology Information

'isometropia' originates from Greek, specifically the elements 'iso-' and 'metropia', where 'iso-' meant 'equal' and 'metropia' related to 'metron' meaning 'measure' or to refractive condition.

Historical Evolution

'isometropia' is a modern medical formation combining the Greek-derived prefix 'iso-' with the New Latin/Greek-derived medical element 'metropia' (as in 'ametropia'/'ametropia'), and it entered English via medical/ophthalmological usage in the 19th–20th century.

Meaning Changes

Initially formed to denote an equal refractive condition between the eyes; this meaning has been retained in modern ophthalmic usage.
