Definition of perimetry in US English:



  • Measurement of a person's field of vision.

    • ‘Intraocular pressure, the optic nerve, and perimetry provide complementary clues but are not easily combined in population-based screening programs.’
    • ‘Fundoscopy showed severe disc swelling, and perimetry showed visual field defects, which were most extensive in both lower quadrants.’
    • ‘Current evidence suggests that the defect is unlikely to develop if perimetry gives normal results after more than three years of treatment.’
    • ‘But glaucoma in particular could only be detected through eye examinations, and to check thoroughly three tests were needed - ophthalmoscopy, tonometry and perimetry.’
    • ‘In the recent check up I was diagnosed with early stage of chronic open angle glaucoma in both eyes by computerised field perimetry - left eye more than right, although left eye is much less myopic than right one.’
