ARCHETYPE ID	openEHR-EHR-OBSERVATION.visual_field_measurement_draft.v0
Concept	Visual field measurement
Description	Results of visual field testing / perimetry.
Use	To record the results of visual field testing or perimetry. The 'Clinical Description' data element can be used to record simple narrative summary or as a means to integrate legacy data. Detailed, structured visual acuity results are preferred and are generally recorded for each eye in turn.
Misuse	Where the perimetry method or device changes between each eye, a new record Entry should be created at runtime.
Purpose	For recording the results of visual field testing or perimetry.
