What the study is about

The specific aims of the clinical studies are to:

  • Develop a directional high-resolution OCT and OCT angiography prototype to improve imaging of structure and perfusion.
  • Validate wide-field OCT and OCT angiography parameters to improve early glaucoma detection.
  • Simulate visual field results by combining structural and angiography OCT data.
  • Assess abilities of above technologies and OCT-derived parameters on predicting glaucoma detection, conversion, and progression.

Conditions: Glaucoma

Eligibility criteria

Copied from the official record. The study team makes the final decision at screening.

Show full criteria

Inclusion Criteria: Normal Subjects (both eyes must meet all criteria)

  • No history or evidence of retinal pathology or glaucoma
  • Normal Humphrey 24-2 VF: A mean defect (MD), corrected pattern standard deviation (CPSD) within 95% limits of normal reference, and glaucoma hemifield test (GHT) within normal limits (97%).
  • Intraocular pressure \< 21 mm Hg
  • Central corneal pachymetry > 500 microns
  • No chronic ocular or systemic corticosteroid use
  • Open angle (gonioscopy must show 75% or more of the angle to be Grade 2 or more by Shaffer's grading system)
  • Normal appearing ONH and NFL: vertical and horizontal cup/disc ratio (CDR) ≤ 0.5 and intact neuroretinal rim without peripapillary hemorrhages, notches, localized pallor, or NFL defect
  • Symmetric ONH between left and right eyes: CDR difference \< 0.2 in both vertical and horizontal dimensions

Inclusion criteria: Glaucoma Group

  • ONH or NFL defect visible on slit-lamp biomicroscopy defined as one of following:
  • diffuse or localized thinning of the rim
  • disc (splinter) hemorrhage
  • notch in the rim
  • vertical cup/disc ratio greater than the fellow eye by > 0.2
  • Presence or absence of VF defects as measured by Humphrey SITA 24-2 VF.

Exclusion Criteria: All Groups

  • Best-corrected visual acuity less than 20/40
  • Age \< 40 or >85 years
  • Refractive error of > +3.00 D or \< -7.00 D
  • Previous intraocular surgery except for uncomplicated keratorefractive surgery and cataract extraction with posterior chamber intraocular lens implantation
  • Diabetic retinopathy
  • Other diseases that may cause VF loss or optic disc abnormalities
  • Inability to clinically view or photograph the optic discs due to media opacity or poorly dilating pupil
  • Inability to perform reliably on automated VF testing
  • Life-threatening or debilitating illness making it unlikely patient could successfully complete the study.
  • Refusal of informed consent or of commitment to the full length of the study
