• Evidence of diabetic retinopathy, diabetic macular edema, or other vitreo–retinal
disease.
Systemic:
• History of diabetes, leukemia, AIDS, uncontrolled systemic hypertension, dementia or
multiple sclerosis.
• A life threatening or debilitating disease.
• Current or recent (within the past 14 days) use of an agent with photosensitizing
properties by any route (e.g., Visudyne®, ciprofloxacin, Bactrim®, doxycycline, etc.).
Normal subjects were defined by Principal Investigators at each site after review of clinical
and visual field data, and considering inclusion and exclusion criteria. The CIRRUS
instrument was not used in determining the normalcy of the subjects.
The subjects were defined as normal if they met the following criteria:
• Best corrected visual acuity of 20/40 or better in both eyes.
• IOP less than or equal to 21 mm Hg.
• No history of ocular, neurological, or systemic diseases that might affect the visual
system.
• Normal visual field, indicated by a Glaucoma Hemifield Test within normal limits, and
MD and PSD > 5% probability level.
Data Collection
315 subjects were qualified as normal subjects and enrolled in this study for the RNFL
Database and for the Macula Normative Database.
For the RNFL Normative Database, each eye was scanned three times with the Optic Disc
Cube 200x200 scan. For the macula normative database, each eye was scanned three
times with the Macular Cube 200x200 scan and three times with the Macular Cube
512x128 scan.
The CIRRUS RNFL and Macula databases do not have subjects with refractive errors
outside the –12.00 D to +8.00 D range. Therefore, the normative limits for subjects with
refractive errors outside the –12.00 D to +8.00 D range should be used with caution.
Scan Selection Criteria
The scans were reviewed for image quality. One best quality scan for each scan type was
chosen for each subject per eye. Scans having the following characteristics were excluded
from the normative database:
• Signal Strength of 5 or lower.
• Large eye motion during image acquisition, resulting in a saccade that was within the
central 80% of the scan area.
• Area of data loss greater than 10% at the edge of the scan area.
• Presence of floater(s) obscuring macular area on Macular Cube scans or measurement
circle on Optic Disc Cube scans.
