What's the difference between perimetry and visual?
Perimetry
Definition:
(n.) The art of using the perimeter; measurement of the field of vision.
Example Sentences:

(10) Automated perimetry allows accurate diagnostic information to be obtained in a reliable manner.
(11) Interindividual spread was greater than intraindividual spread; the spread augmented towards the periphery and in the superior quadrant of the visual field and was generally greater in automated perimetry than in manual Tübingen perimetry, especially in the region of the blind spot.

(15) ), were examined by automated light-sense and temporal resolution perimetry.
(16) Computerized perimetry is related to standard manual visual field examination.
(17) It was established that the changes in static perimetry run a course parallel to the disturbances in the perception of the Haidinger phenomenon and poor performance at the Amsler tests.
(18) A quantitative measure of visual field loss associated with kinetic perimetry in chronic open-angle glaucoma (COAG) is discussed.
(19) Careful quantitative perimetry should be done to decide a suitable time for surgical treatment in BIH.
(20) These findings with dark-adapted perimetry, fundus reflectometry, and dark adaptometry showed intrafamilial and interfamilial consistency.
Visual
Definition:
(a.) Of or pertaining to sight; used in sight; serving as the instrument of seeing; as, the visual nerve.
(a.) That can be seen; visible.
Example Sentences:
(1) The optimal size for stimulation was between 5 degrees and 12 degrees (visual angle).
(2) The effects of sessions, individual characteristics, group behavior, sedative medications, and pharmacological anticipation, on simple visual and auditory reaction time were evaluated with a randomized block design.
(3) Immunocytochemistry was used to visualize cytoskeletal structures and to assay selective disruption of neurofilaments by acrylamide.
(4) Only the approximately 2.7 kb mRNA species was visualized in Northern blots of total cellular and poly(A+) RNA isolated from cardiac ventricular muscle.
(5) During the chronic phase, pain was assessed using visual analogue scales at 8 AM and 4 PM daily.
(6) The high incidence of infant astigmatism has implications for critical periods in human visual development and for infant acuity.
(7) By means of two monoclonal antibodies, which were directed against external and internal acetylcholine (ACh) receptor epitopes, we were able to visualize ACh-receptors on OHCs.
(8) Long term follow up of extracapsular extraction showed visual results superior to those previously reported for intracapsular extraction.
(9) They were visualized by indirect immunoperoxidase techniques.
(10) We have now started a prospective follow-up study in order to pursue the development of (a) p-ERG amplitudes and (b) funduscopic changes and visual acuity in these patients.
(11) Lysates of lymphoblastoid cells provided the antigen source which were visualized by sodium dodecyl sulfate polyacrylamide gel electrophoresis.
(12) At this threshold there was no effect on reducing the rate of visual acuity overreferrals, but ten children with abnormal binocular vision were detected who were not referred by visual acuity criteria.
(13) It is commonly assumed that the visual resolution limit must be equal to or less than the Nyquist frequency of the cone mosaic.
(14) Degraded visual acuity had a significant effect on cadence, foot placement, and foot clearance, but visual surround conditions did not.
(15) On the initial visit, the best corrected acuity with spectacles was determined and a potential acuity meter reading was obtained; this test suggested potential for visual recovery in two of the three patients.
(16) Assessments were made daily by patients, using visual analogue scales, of their pain levels at rest, at night and on activity, and of the limitation of their activity.
(17) II, the visual and auditory stimuli were exposed conversely over the habituation- (either stimulus) and the test-periods (both stimuli).
(18) Most survivors reported a range of problems that they attributed to having had cancer: 35%, proven or perceived infertility; 24%, sexual problems; 31%, health and life insurance problems; 26%, a negative socioeconomic effect; and 51%, conditioned nausea, associated with visual or olfactory reminders of chemotherapy.
