Introduction.
The paper presents a commentary on the method of analysis of corneal vibrations occurring during eye pressure measurements with air-puff tonometers, for example, Corvis.
The presented definition and measurement method allow for the analysis of image sequences of eye responses—cornea deformation.
In particular, the outer corneal contour and sclera fragments are analysed, and 3D reconstruction is performed.
Methods.
On this basis, well-known parameters such as eyeball reaction or corneal response are determined.
The next steps of analysis allow for automatic and reproducible separation of four different corneal vibrations.
These vibrations are associated with (1) the location of the maximum of cornea deformation; (2) the cutoff area measured in relation to the cornea in a steady state; (3) the maximum of peaks occurring between applanations; and (4) the other characteristic points of the corneal contour.
Results.
The results obtained enable (1) automatic determination of the amplitude of vibrations; (2) determination of the frequency of vibrations; and (3) determination of the correlation between the selected types of vibrations.
Conclusions.
These are diagnostic features that can be directly applied clinically for new and archived data.
