Summary: Purpose: SOCT is a new variant of optical tomography that enables to provide tomograms of improved quality due to very short acquisition time and high sensitivity. The aim of the study is to assess the ability of SOCT with central wavelength of 830nm to visualize filtering blebs in vivo. Material and methods: A total number of 33 eyes 6 months to 2 years after trabeculectomy were enrolled. After slit-lamp examination and colour photography, 830 nm SOCT was performed with the aid of the prototype instrument constructed at the Institute of Physics, Nicolaus Copernicus University, Toruń, Poland. Results: Tomograms with resolution of 4,5 x 10 ?m were acquired. The quality of images allow cross-sectional analysis of filtering blebs morphology in vivo. Due to the limited penetration of 830 nm light and high reflectivity of tissues, the sclera beneath the bleb was visualized only in some cases. Conclusions: 830 nm SOCT allows cross-sectional imaging of filtering blebs that may be useful in research. However due to the limited light penetration clinical value may be limited.

Keywords: SOCT, trabeculectomy, filtering bleb.
