Field Testing Many procedures have been developed for evaluation of the peripheral visual field, and their use depends on the availability of equipment and resources, the physical and mental status of the patient, and the time available for testing.16,17 The most common qualitative procedure is known as confrontation visual field testing.

Evaluation of 105 eyes (61 with defects, 44 normal) revealed a 98.5% detection rate and a 4% false alarm rate for the Fieldmaster in comparison with Goldmann kinetic perimetry. Based on these results, the Fieldmaster appears to have great potential value as a quantitative visual field screening device for the detection of visual field defects.

With the cooperation of the California Department of Motor Vehicles and Synemed; Inc., visual field screening tests were administered to 1,027 eyes of…

In our mass visual field screening studies, the prevalence of visual field loss was between 3.0% and 3.5% for all age groups between 16 and 60. Between 61 and 65, the prevalence rose to 6.0%, and over 65 years of age the prevalence of visual field loss was greater than 13%. Followup questionnaires revealed that cataracts, glaucoma and retinal ...

Visual field testing can detect blind spots. A visual field test can determine if you have blind spots (called scotoma) in your vision and where they are. A scotoma's size and shape can show how eye disease or a brain disorder is affecting your vision. For example, if you have glaucoma, this test helps to show any possible side (peripheral ...

Field Master Pro Overview. Ideal for a range of current and emerging applications, the Field Master Pro series consists of seven models with frequency coverage of 9 kHz to 9/14/20/26.5/32/43.5 and 54 GHz. The family features best-in-class performance, such as Displayed Average Noise Level (DANL) of <-160 dBm and Third Order Intercept (TOI) of ...

Each eye is tested separately and the entire test takes 15-45 minutes. Your optometrist may ask only for a driving licence visual field test, which takes 5-10 minutes. If you have just asked for a driving test or the clinic doctor advised you have one, you will be informed of …

Automated visual field screening in the flying Dutch population. Van Dalen JT. Results of automated perimetry (Fieldmaster 200, Synemed) in 1,000 subjects are described. In 17 subjects (1.7%) a serious field defect was found. In 9 subjects (0.9%) aspecific defects were found.

With continuous frequency coverage from 9 kHz to 54 GHz, the Field Master Pro MS2090A is specifically designed to meet the test challenges of a full range of other wireless technologies in use today, including: 5G, LTE, wireless backhaul, aerospace/defense, satellite systems, and radar. The Field Master Pro MS2090A delivers the highest levels ...

Automated visual field screening of 10,000 volunteers (20,000 eyes) showed the incidence of visual field loss was 3.0% to 3.5% for persons aged 16 to 60 years but was approximately 13.0% for those ...

To the Editor .—We recently employed an automated visual field plotter (Fieldmaster; manufactured by Synemed Inc, Berkeley, Calif) utilizing "suprathreshold static perimetry" as described and evaluated by Keltner et al. 1 We were looking for an easyto-use device that yielded reliable and accurate visual fields under standard conditions. We were hoping that this method would decrease test ...

5. Light threshold profile of the visual field through two opposite meridians. necessary to explore any part of the visual field. They adapt easily to all three methods of perimetry: kinetic, threshold static, or suprathreshold static allowing a perimetest to combine methods while testing any patient.

The efficacy of automated suprathreshold perimetry with Fieldmaster automated perimeter (model 101 PR and 200) was evaluated in the screening for very early glaucomatous visual field defects which failed to be detected with kinetic perimetry using a Goldman perimeter. Evaluation of 117 eyes with ele …
