perimetric

Perimetric is an adjective meaning relating to a perimeter, the length of the boundary of a two-dimensional figure or the boundary of any closed curve. It is used to describe measurements, properties, or problems that involve the boundary length of shapes or regions.

In geometry and mathematics, perimetric is used in phrases such as perimetric problems and perimetric inequalities. A classic example is the isoperimetric inequality, which states that among shapes with a given perimeter, the circle encloses the maximum possible area. Perimetric considerations also arise in design, optimization, and analysis when the boundary length is a key constraint.

In medicine, particularly ophthalmology, perimetric relates to perimetry, the testing of a patient’s visual field. Perimetric tests map the extent of vision and are used to detect field defects associated with conditions such as glaucoma. The term helps distinguish measurements that concern the boundary of vision from central visual acuity.

In practical usage, perimetric descriptions may specify measurements or properties tied to a boundary, such as perimetric length or perimetric accuracy, though these terms are most common in technical or academic contexts. Overall, perimetric denotes aspects connected to the perimeter of shapes or boundaries in both mathematical and applied settings.
