NCT02526654

Brief Summary

The purpose of this study is to compare standard automated perimetry (SAP) using the Heidelberg Edge Perimeter (HEP) to the Octopus Visual Field (OVF) analyzer and determine test-retest reliability of both parameters in detecting glaucomatous visual field losses. This study will also investigate novel imaging parameters of the optic nerve head and new automated structure-function reports.

Outcome Measures

Primary Outcomes (1)

  • Correlation Coefficient Between HEP and OVF Mean Deviation (MD)

    Pearson's correlation coefficient between Heidelberg Edge Perimeter (HEP) and Octopus Visual Field (OVF) Mean Deviation (MD) for glaucoma patients and controls to determine if HEP can detect glaucoma as well as OVF. The closer the values of both parameters for both machines, the better comparable the two machines are to each other in detecting glaucoma.

    Baseline visit, 1 hour

Secondary Outcomes (2)

  • Repeatability of Optical Coherence Tomography (OCT) Parameters

    Month 6 visit, 1 hour

  • Correlations Between Structure-function Automated Report and Clinical Impression

    Baseline visit, 1 hour

Study Arms (2)

Glaucoma Subjects

EXPERIMENTAL

Subjects with glaucoma were recruited based on characteristic glaucomatous disc damage and visual field changes. They will perform visual field with Heidelberg Edge Perimeter and Octopus visual field. Optical Coherence Tomography will image the retinal nerve fiber layer.

Diagnostic Test: Heidelberg Edge PerimeterDiagnostic Test: Octopus Visual FieldDiagnostic Test: Optical Coherence Tomography

Healthy Controls

EXPERIMENTAL

Subjects that do not have glaucoma and are recruited for testing will perform visual field with Heidelberg Edge Perimeter and Octopus visual field. Optical Coherence Tomography will image the retinal nerve fiber layer.

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age \> 18 years.
  • Best corrected visual acuity of 20/40 or better in the tested eye.
  • Spherical refraction within ±5.0 D, and cylinder correction within ±3.0 D.
  • History of glaucoma, defined as:
  • Characteristic of glaucomatous disc damage: (local narrowing, notching, or absence of the neuroretinal rim in the absence of disc pallor elsewhere).

You may not qualify if:

  • Any condition preventing adequate examination of the pupil or visual field testing (e.g. ptosis, dense corneal opacities or lens opacities);
  • Active infection of the anterior or posterior segments of the eye;
  • Any intraocular surgical or laser procedure within the previous 4 weeks;
  • Participants taking a medication known to affect visual field sensitivity, a coexisting intraocular disease affecting visual field, or a problem other than glaucoma affecting color vision will be excluded.
