Collect OCT data to evaluate the range and age trend of ocular measurements.
||Observational Model: Case-Only
Time Perspective: Prospective
||Optical Coherence Tomography (OCT) Data Collection Study "S-2012-1 Norm-cc"
Primary Outcome Measures:
- Primary Endpoints [ Time Frame: 3 months ] [ Designated as safety issue: No ]
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.

| Primary Completion Date:
||December 2012 (Final data collection date for primary outcome measure)
This is a prospective, multi-center study. Ocular history and examination will be conducted on consented subjects to determine further participation in the study. Subjects qualified to continue will undergo imaging of both eyes using the SPECTRALIS OCT.
|Ages Eligible for Study:
||18 Years to 90 Years
|Genders Eligible for Study:
|Accepts Healthy Volunteers:
- 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.
