Seeing, what otherwise would stay invisible…
High Speed Kamera
In 2015, the laboratory equipment of ACTO was expanded with a high-speed video camera (Optronis CR3000x2) to enable optimal documentation of the temporal unfolding of processes on biological interfaces. A sensor resolution of 1,696 x 1,710 pixels guarantees a high-precision imaging. With the camera, videos can be taken with up to 100,000 pictures per second, which also makes the fastest processes visible. Moreover, the pictures can be further refined with a special analysis software.
Good experiences with the camera could already be gained through the recording of vitrectomy cutter motions. The cutter motions, the exact duty cycle or the resulting retinal motions can be analyzed well with the videos. Likewise interesting and informative are the videos that show the fluid motions of triamcinolone-stained vitreous bodies. Furthermore, this imaging technology allows processes to be presented during phacoemulsification.
The high-speed camera can also be applied for the detailed imaging of the various spreading behavior of eye drops on the corneal surface. Regarding this question, in vitro experiments were conducted on rabbit- and porcine eyes while in vivo experiments were conducted on volunteers.
In another future step, it ought to be possible to intra-operatively realize further analyses of vitrectomy by coupling the high-speed video camera to an operation microscope.
