Diagnostic procedures
Slit lamp
The slit lamp (slit lamp microscope) is one of the most important ophthalmic examination devices. Using a microscope, the examiner can look at the eye with varying magnification:
- through different types of exposure (diffuse, direct, indirect, focal, regressive, etc.)
- with different light gap widths
- from the front to the back of the eye, possibly with additional optics.
Corneal topography
In this procedure, originally only the surface of the cornea was measured by the projection of concentric rings of light, later also luminous dots or slit images. However, modern devices also allow the measurement of the corneal surface, the corneal thickness of one certain area, the shape, the refractive power and radii, the astigmatism. In addition, there is information about the anterior chamber depth and shape and much more.
Corneal OCT
The optical coherence tomography (OCT) allows (in addition to the known diagnosis of the retina) investigation of the cornea, anterior chamber and partially the dermis. In particular, in the non-contact examination, the layers of the cornea can be precisely represented in the sectional image.
Varia
Depending on the diagnostic question, different examinations may be used, e.g.
- the measurement of the corneal diameter
- a tear fluid analysis
- a measurement and evaluation of the posterior cell layer of the cornea (endothelial biomicroscope)
