NCT02862158

Brief Summary

This is a single center, prospective study to evaluate the efficacy and reproducibility of frequency doubling technology (FDT)-based visual field devices compared to conventional Humphrey Visual Field (HVF) perimetry. The investigators plan to enroll 500 patients in this study.

Outcome Measures

Primary Outcomes (1)

  • Pattern of visual field loss in FDT visual fields as compared with standard HVF

    Visual Field

    The investigators anticipate to enroll the subjects over a period of 12 months. The estimated time required for data analysis is 6 months following enrollment of all subjects.

Secondary Outcomes (2)

  • Mean deviation (MD) in FDT visual fields as compared with standard HVF

    The investigators anticipate to enroll the subjects over a period of 12 months. The estimated time required for data analysis is 6 months following enrollment of all subjects.

  • Pattern standard deviation (PSD) in FDT visual fields as compared with standard HVF

    The investigators anticipate to enroll the subjects over a period of 12 months. The estimated time required for data analysis is 6 months following enrollment of all subjects.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Adult patients (18 and over) who speak English, Spanish or Creole, and are capable of providing informed consent and who have a Humphrey Visual Field (HVF) test within the prior the 6 months preceding enrollment are eligible for enrollment in this non-invasive study. Patients will be recruited from among patients at the Bascom Palmer Eye Institute clinics during their regularly scheduled clinic visits. No advertising will be used to recruit patients.

You may not qualify if:

  • Adults unable to consent, individuals who are not yet adults (infants, children and teenagers), pregnant women and prisoners and other vulnerable populations will be excluded from the study.
