Campimetry

(8) The influence of suction cup oculopression on the perception of the white-noise field is shown in some glaucoma patients: the speed of the white-noise campimetry allows the increase in field defects during artificial IOP elevation to be followed up directly.
(9) The results of white-noise campimetry were compared with conventional raster perimetry using the Tübingen automatic perimeter.
(10) We were interested in finding whether absolute and relative scotomas could be detected with such high probability that snow field campimetry could be used as a screening method for the early detection of glaucoma.
(11) However, in white noise campimetry the blind spot usually cannot be perceived: the white noise is continuous over the whole field if presented to a normal eye.
(12) On the other hand, the blind spot is always perceived in white-noise campimetry if acquired damage to the peri-cecal region is present.
(13) In 12% of eyes light-sense perimetry indicated defects while the result of noise-field campimetry was normal, and in 11% of eyes noise-field campimetry showed defects though there was a normal field according to light-sense perimetry.
(14) The results demonstrate the usefulness of white-noise-field campimetry as a very fast screening method for detecting glaucomatous visual field defects.
(15) For a timely prescription of dedystrophic treatment, the authors recommend to use color campimetry for examination of both eyes of the patients with monolateral macular dystrophy as well as in persons addressing for selection of glasses or undergoing preventive examination.
(16) For diagnosing subclinical forms of central sclerotic dystrophies of the retina the authors propose to use color campimetry with the help of standard color glasses or a device suggested by them.
(17) In 110 eyes of 63 of the glaucoma patients, white-noise-field campimetry was carried out during artificial IOP elevation achieved by suction-cup oculopression: during steplike increases of the negative pressure in the suction-cup up to maximum of 375 mmHg the following stages could be seen (the percentage of eyes that perceived each phenomena over the negative pressure range is shown in brackets): change in NF perception compared with initial findings (96.4%); impairment of central noise-field perception (78.2%); concentric constriction of NF (61.8%); complete breakdown of noise (field) perception (42.7%).
(18) These cases do not show any scotoma under campimetry on the phase difference haploscop (Aulhorn).
(19) Thus, metamorphopsias were revealed on the Amsler's grid in 193 eyes (57%), changes by means of campimetry--in 171 eyes (51%), while dynamic scotoma disadaptation was revealed in 337 eyes (100%).
(20) The neuro-ophthalmological examination of homonymous hemianopia: qualitative perimetry (confrontation tests), quantitative perimetry (campimetry on the Bjerrum screen, kinetic perimetry, static perimetry, automatic computer controlled perimetry, perimetry with colours, flickerfusion frequency-perimetry), oculomotor disturbances (gaze strategies, opto-kinetic nystagmus), pupillary disturbances, visual evoked potentials, anosognosia, Riddoch-phenomenom, hemiachromatopsia.
Perimetry
Definition:
(n.) The art of using the perimeter; measurement of the field of vision.
Example Sentences:
(1) Patients should be evaluated by perimetry using an appropriate strategy and contrast sensitivity testing, along with careful examination of the optic discs.
(2) Perimetry is a subjective psychophysical sensory examination.
(3) During automated perimetry with the Humphrey Visual Field Analyzer, field examinations are labeled unreliable whenever the reported rate of fixation loss is 20% or more.
(4) The black hole effect is probably of minor clinical importance except in exacting quantitative perimetry.
(5) The future development of perimetry will be characterized by a refinement of measured value statistics and the testing of perimetric procedures that test more complex physiological functions than sensitivity to differences (e.g., analysis of temporal transmission characteristics in flicker perimetry.
(6) The influence of a socially acceptable dose of alcohol (mean blood alcohol level approximately 90 minutes after ingestion 69.5 mg%; SE 6.20 mg%) on the central visual field as determined by automated static perimetry was investigated in 17 female subjects (17 eyes) trained in automated perimetry (mean age 22.5 years, SE 1.29 years).
(7) Kinetic perimetry was performed using colored test objects of constant luminance, equated to a white surround of 10 ft lamberts.
(8) The test is entitled 'Oculo-Kinetic Perimetry' because it is the subject's eye that moves and not the test stimulus.
(9) To study such possible factors, we carried out perimetry on subjects who had consumed alcohol and who had not.
(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.
(12) Perimetry is, therefore, recommended to diagnose or rule out a neuropathy.
(13) Suppression was examined with binocular perimetry in patients with small angle strabismus.
(14) The advantages and the disadvantages of automated perimetry in respect to manual perimetry are examined.
(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.
