Conclusion
The CIRRUS HD-OCT Ganglion Cell Analysis normative database was created using data
from subjects that were deemed representative of a normal population. To establish
reference values, the scans acquired as part of the CIRRUS HD-OCT Macular Thickness
normative databases were analyzed using a segmentation algorithm that identifies the
thickness of the combined ganglion cell plus inner plexiform layers. The doctor can use the
Ganglion Cell Analysis normative database to compare individual patient measurements of
Ganglion Cell Analysis parameters to those acquired in a normal population.
Asian Normative Database

Overview
The Asian Normative Database is a licensed feature. It enables you to choose whether to
apply the Asian or Diversified Normative Database to each patient, as part of the patient
record.
When you license the Asian Normative Database, you are prompted to select a default
database that will be applied to patients. After selecting the default, all new and existing
patients will be assumed to be the default unless you manually select another database for
that specific patient.
For details on how to select or change the normative database, see the “Add New
Patients” on page 5-2 .
Introduction
The Asian Normative Database was developed using sites located in Japan, China, and
India. The Asian normative data was collected and analyzed in a manner identical to the
collection of the diversified data. Details are described in this section.
The Asian Normative Database was intended to collect normative data for retinal nerve
fiber layer (RNFL) and macular thickness from healthy subjects ages 19 to 79. Post–hoc
analysis was performed to create normative limits for Optic Nerve Head (ONH) analysis and
Ganglion Cell Analysis as well.
Five new centers participated in the prospective, non–randomized, multi–center study.
Data from a site in Hong Kong which was included in the Diversified Normative Database
was also included in the Asian Normative Database.
4The Asian Normative Database is an optional feature that may not be available in all markets, and when available in a market, may not
be activated on all instruments. If you do not have this feature and want to purchase it, contact Carl Zeiss Meditec. In the U.S.A., call
