The measuring system of the IOLMaster is capable of resolving fine
structures on the fundus of the eye.
Depending on the anatomical conditions of the measured eye it may
happen that the measuring beam produces interferences when being
reflected at the inner limiting membrane and/or the choroid.
This is indicated by
Ć broader signal peaks of the measuring curve,
Ć variations of axial length data of approx. 0.15 Ć 0.35 mm in one
measurement series and
Ć display of Evaluation" in place of mean value.
Example:
or or or
Such measuring curves or measurement series absolutely require
verification. This can be done both between the individual measureĆ
ments (in ALM mode) and in post measurement editing (without the
patient sitting in front). Interpretation or post measurement editing
should always be done with the help of the zoom function.
Note:
The resolution of fine retinal structures is clearly distinguishable
from the previously mentioned secondary maxima. The secondary
maxima (2) are much further distant from the retinal pigment
epithelium signal peak and they are symmetrical to it.
The distance between the maximal peak and internal limiting
membrane or choroid is 0.15 Ć 0.35 mm (whereas the secondary
maxima are about 0.8 mm displaced from the maximal peak!).
