{{Short description|Ophthalmic instrument for examining the visual field}} The '''campimeter''' is an instrument for examining the visual field.<ref>{{cite web |url=http://medical-dictionary.thefreedictionary.com/campimeter |title= Campimeter |publisher=TheFreeDictionary's Medical Dictionary |accessdate=6 January 2009}}</ref> Campimeters have been in clinical use since the mid-nineteenth century. Initially, examination of the visual field was concerned only with the outer limits, or 'perimeter' of the visual field, hence the term 'perimetry', which tends to be used inter-changeably with 'campimetry'.
