Analysis Protocols

6-8
• The thinnest 5% of measurements fall in the yellow area or below
(1%  yellow < 5%, suspect below normal).
• The thinnest 1% of measurements fall in the red area. Measurements in red are
consider
ed below normal limits (red < 1%, below normal limits).

Note: Clinicians must exercise judgment in the interpretation of the macula
normative data. For any particular measurement, note that 2 out of 20 normal eyes
(10%) will fall either above or below green.
Edit Layers


Version 5.0 and higher of Stratus OCT software includes the ability to
edit layers, that is, to
manually adjust the placement of the retinal layer boundaries, between which Stratus
measures the retina and RNFL thickness. The functionality described in this section is
available with all of the Analyses and Reports (see the list on page 6-2), except the
Optic Nerve Head analysis, which has a similar but distinct in
teractive capability.
Carl Zeiss Meditec designed the edit layer capability to give you direct control over
pla
cement of the retinal layer boundaries, enabling you to substitute your judgment in
place of the automated outcome of the Stratus thickness algorithms. This is especially
useful in cases where the retina has structural anomalies or pathology that may cause the
algorithms to incorrectly trace the actual boundaries.

When any applicable analysis is open, the Edit Layer butto
n becomes available, as well as
the Edit Layer option in the Data menu.
When available, click the Edit Layer button in the
toolbar or select Ed
