In ICTER we are working on novel method of eye fundus (retina) imaging which use a two-photon absorption of a laser light. The measurements are non-invasive and safe (there is no contact of the patient’s eye with the measurement setup, used laser radiation is below the maximum exposure limit of the laser light for the human eye). Using the two-photon absorption is necessary as eye (in fact mainly cornea) absorbs and scatters blue light, which is normally absorbed by the photosensitive cells responsible for the vision process. Thus just small amount of light reach the retina and enable imaging – using two-photon phenomena (we use near-infrared light for which the eye is almost transparent) enables excitation of particular molecules, with good spatial resolution. The method is general, fast and robust – in dozen of minutes we can register the fundus of the eye. Previous experiments made on mice models have confirmed the validity of the method, but the current challenge are the measurements on humans, realized in our group. The next step is a trial of correlation of the registered images with different retinal diseases in such a way that based on the measurement results provide early diagnosis and choose the most promising direction of treatment.

TASK: For the method to be used in an ophthalmologic office, we need a precise and repeatable eye positioning in front of the scanning laser beam. One of the most important part is so-called fixation system – one one is measure while another follows the light spot. Due to the optometric reflex movements of both eyes are synchronized. We plan to expand the current fixation system to enable the steering via microcontroler the position of the light spot and additionally without optical lens therein (thanks to 3D printed elements). Thanks to the above, the eye positioning will be more reliable and patient’s measurement faster.More information about realizing projects you can find on our website: SUMMER INTERNSHIP / PAID TRAINEESHIP – ICTER
