perimetric
Concerning outer limits
Perimetric means relating to or measured along a perimeter—the outer boundary of a shape or area.
The term appears in geometry and technical contexts: perimetric calculations, perimetric measurements.
In ophthalmology, perimetric refers to visual field testing, which maps the boundaries of peripheral vision: perimetric examination revealed early glaucoma.
