Universal ophthalmic examination device and ophthalmic examination method
First Claim
1. A universal ophthalmic examination device comprising, in combination with a central control unit:
- at least one primary light source in an illumination beam path directed to an object being examined;
at least one image recording and evaluating unit for documenting and/or for measuring at least partial areas of the object being examined;
electronically switchable elements for beam path switching;
an optical light manipulator which communicates with the central control unit and which being jointly controllable being arranged in the illumination beam path provided for the at least one primary light for program-oriented modification of the intensity curve and/or time curve of the primary light in a temporally defined relationship with the adjustments of the primary illumination and of the image recording and evaluation; and
a secondary light that is generated from the primary light by the modification being provided for illumination and for selective stimulation of the object to be examined.

Abstract
A universal ophthalmic examination device and an ophthalmic examination method have the object of combining in an inexpensive apparatus in a simple manner the device-related requirements for image generation, measurement and functional imaging for carrying out visual stimulation and highly time-resolved and highly spatially resolved image documentation using continuous illumination and flash mode and the requirements for measurements in the infrared spectral region and visible spectral region with a time regime that can be freely selected to a great extent. The light of at least one light source is modified in a program-oriented manner with respect to its intensity curve and/or time curve with a temporally defined relationship to the adjustments of the at least one light source, of the image recording and of the evaluation for purposes of adaptive matching to an examination task in the illumination beam path by an individual, shared light manipulator and is used as modified light for illumination and for selective stimulation.

12. An ophthalmic examination method including the steps of:
-
illuminating an object to be examined and selectively stimulating it by an illumination beam path for recording images with light of at least one light source;
deriving examination results by recording images of the object to be examined and evaluating the images obtained by the image recording; and
modifying the light of the at least one light source in a program-oriented manner with respect to its intensity curve and/or time curve with a temporally defined relationship to the adjustments of the at least one light source, of the image recording and of the evaluation for adaptive matching to an examination task in the illumination beam path and using such modified light for illumination and for selective stimulation. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
