Brief Summary

This study is being initiated to create a normal database including measures of optic nerve head (ONH), peripapillary retinal nerve fiber layer (RNFL), and macula using the Heidelberg Spectralis OCT device.

Outcome Measures

Primary Outcomes (1)

• Normative Data for optic nerve head, the peripapillary retinal nerve fiber layer, and the macula.

  This normal database will be used to determine if an unknown subject has measurement values "within normal limits" or "outside normal limits." It is planned to classify an eye "within normal limits" if the measurement value is greater than or equal to the 5th percentile of the normal distribution (or less than or equal to the 95th percentile), and as "outside normal limits" if the measurement value is smaller than the 1st percentile (or larger than 99th percentile) of the normal distribution. Thus, the sample size must be large enough to ensure that the 1st and the 5th percentiles of the distribution are distinct.

Eligibility Criteria

• Age: 18 Years - 90 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Probability Sample

Study Population

Recruitment will be from persons who respond to recruitment initiatives at the individual centers or have signed a release saying that they are willing to be approached for participation in research. At least 87 subjects (enrollment target: 135 subjects) will be selected from qualifying normal volunteers. Age range will be from ≥18 to 90 years. The age of the subjects will be defined by their month of birth versus the month of giving consent to participate in this study. A subject who is 40 years and 11 months old will be counted as being in the age group "31 to 40 years". Each site will attempt to recruit subjects in about equal numbers in each age group. The distribution in the age groups should be fairly equal among subjects in each ethnic group alone.

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 without clinically significant vitreal, retinal or choroidal diseases, clinically significant diabetic retinopathy (subject may have diabetes), or disease of the optic nerve. Small Drusen are acceptable in older subjects.
• Hispanic Descent, Black or African American Descent, Asian Descent, American Indian or Alaskan Native Descent
• 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, or not abnormal visual field by judgment of the ophthalmologist.
• 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.

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.
