Outcome Measures

Primary Outcomes (2)

  • Primary Endpoints

    The primary endpoints are the structural measurement values of (1) the ONH, (2) the peri-papillary RNFL, and (3) the macula obtained using the Spectralis OCT and the statistical descriptors such as mean, standard deviation, and distribution percentiles.

    3 months

  • Bruch's Membrane Opening - Minimum Rim Area, Global

Eligibility Criteria

Age18 Years - 90 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

No eye disease.

You may qualify if:

  • Subject is not an employee of the eye clinic.
  • Age ≥18 to 90.
  • Able and willing to undergo the test procedures, give consent, and to follow instructions.
  • Healthy eye without prior intraocular surgery (except cataract surgery and Lasik) and without clinically significant vitreal, retinal or choroidal diseases, diabetic retinopathy, or disease of the optic nerve.
  • Caucasian decent (self-reported).
  • Negative history of glaucoma.
  • Intraocular pressure ≤21mmHg.
  • Best corrected visual acuity ≥0.5.
  • Refraction between +6 and -6 diopters and astigmatism ≤ 2 diopters.
  • Normal visual field with Glaucoma Hemifield Test and Mean Deviation within normal limits.
  • Clinically normal appearance of the optic disc, with normal appearing neuroretinal rim with respect to color and shape. The optic disc is examined ophthalmoscopically and by evaluation of stereo photographs.
  • When both eyes are eligible, both eyes enter the study for inter-eye asymmetry; one randomly selected eye will be used for all other measures.

You may not qualify if:

  • Unreliable visual field. The reliability indices should be used as guide as well as the perimetrist's notes.
  • Unusable disc stereo photos.
  • Inability to undergo the tests.
  • Insufficient quality of Spectralis OCT images (this is not determined until after Spectralis OCT examination, and is an unusual circumstance). Minimum requirements are:
  • Retina completely included in image frame,
  • Quality Score ≥ 20 in the stored ART mean images, and
  • For ONH-R scan: Center position error ≤ 100 μm.
  • Note: Inability of a subject to perform one of the two scan patterns or insufficient image quality in one scan pattern does not exclude the subject or eye from the study.
