ARCHETYPE ID	openEHR-EHR-OBSERVATION.visual_field_measurement.v0
Concept	Visual field measurement
Description	Results of visual field testing / perimetry.
Use	Use to record the results of visual field testing or perimetry. Use to incorporate the narrative descriptions of clinical findings within existing or legacy clinical systems into an archetyped format, using the 'Clinical Description' data element. Detailed, structured visual acuity results are preferred and are generally recorded for each eye in turn. If the method of measurement or device is changed for the testing of the second eye, record the second eye's data in another instance of data which captures the new method or device.
Purpose	To record the results of visual field testing or perimetry.
