Binarization of choroidal tissue in optical coherence tomography

* OCT thickness data provides valuable clinical information about the vascular choroid, but does not capture the complex within tissue structure. * Binarization of OCT images of the choroid can provide valuable information regarding the structure of the tissue by discriminating vascular and interstitial areas. * Recent studies have used binary techniques to quantify the vascular/interstitial ratio to better understand within layer changes in a variety of conditions. Yet evaluation of these algorithm’s performance is still limited. * In this study, previously proposed local binarization algorithms for choroidal OCT images were evaluated, using data from a healthy pediatric population (10-16 years of age)
