General Tips
The following general information and usage tips apply to all analysis protocols. Starting
with Retinal Thickness/Volume on page 6-13, this chapter provides a description and
specific usage tips for each protocol.
Analysis Protocols Are Correlated wit
h Scan Patterns
When selecting a protocol, it is
important to remember that the protocols are of two kinds:
image processing protocols and quantitative analysis protocols. Carl Zeiss Meditec
designed the image processing protocols for use with any scan. However, each quantitative
analysis protocol is designed for use with a certain scan type (line or circle) or scan pattern
made on a certain retinal location (macula or disc). Several of the scan protocols are
designed for use with a specific analysis protocol, or with a limited subset of analysis
protocols. An analysis protocol might work on an unintended scan type, but even if it does,
it may not provide meaningful output. The table below shows the scan protocols designed
for each quantitative analysis protocol.
