英文摘要
ABSTRACT
Our parent Phase II SBIR project seeks to develop effective diagnostic solutions for glaucoma,
which is one of the leading causes of adult blindness in the United States and globally. Specific
tasks undertaken are the collection of ocular blood flow data using our proprietary XyCAM
technology from 150 human subjects in the glaucoma clinic at baseline and following hyperoxia,
and the subsequent analysis of acquired data to identify biomarkers for early diagnosis of
glaucoma. In particular, the plan is to evaluate the suitability of our approach in up to 30 subjects
with a high degree of myopia (refractive error of more than 6 Diopters). We are requesting this
administrative supplement to the parent grant to overcome certain data analysis challenges that
have become apparent since we started the project. Notable among these is the need for
registration of data acquired by the XyCAM to the data acquired by other instruments, and also
to the data acquired by the XyCAM at other time points (such as post-hyperoxia) so that data
analysis can be conducted at a regional level in a reliable and standardized manner. We propose
to develop certain automated techniques by utilizing computer vision and machine learning
approaches to support analyses of large volumes of data as will be collected during this study. In
addition to these proposed activities facilitating project goals in the short term, we also anticipate
that the developed software will prove useful more broadly in the future for multi-modal or
longitudinal comparison of XyCAM-generated ocular blood flow data.
