Toward Early Glaucoma Diagnostics: The Use of Nonlinear Optical Imaging Techniques
Dr. Tim Lei
Department of Electrical Engineering
University of Colorado Denver
Glaucoma has been the leading cause of blindness in the United States and affects 60 million people worldwide. One of the major risk factors of Glaucoma is the evaluation pressure of the intraocular fluid. The increased fluid pressure in the eye is believed to cause damages to the optical nerves and ultimately results in permanent loss of vision. Therefore, it is important to develop non-invasive optical imaging techniques to identify early degeneracy in the fluid outflow system inside the eye to prevent the fluid pressure build up. Nonlinear optical imaging techniques allow functional and molecular specific imaging in biological tissues without the needs of exogenous fluorescent labels. In this talk, I will discuss the technical challenges of imaging the trabecular meshwork, which is the entrance of the outflow system of the eye and our achievements of using nonlinear optical techniques including second harmonic generation, two-photon excitation autofluorescence and coherent anti-Stokes Raman scattering microscopy to achieve excellent imaging resolutions and to extract valuable diagnostic information to determine the health of the fluid outflow system in the eye to determine early onsets of glaucoma.
Prof. Tim C. Lei is an assistant professor in the Electrical Engineering Department at the University of Colorado Denver. In addition, he also holds adjunct appointments of the Departments of Bioengineering, Physiology and Biophysics, and Medicine at the University. His research interests focus on applying and developing advanced optical imaging and spectroscopic techniques to study important biomedical problems. Several projects that he is currently researching include: 1) developing nonlinear imaging techniques for early glaucoma detection and diagnostics, 2) measuring protein dynamics and interactions using fluorescent correlation techniques in cell membranes and in lipid rafts for renal diseases, and 3) determining the optical scattering properties of brain tissue to understanding neural circuitry functions using optogenetic proteins.

Middle School MESA Day competition draws 600 students
On Friday April 13, approximately 600 middle school students from around the state converged on the Auraria Campus for the Middle School MESA Day Competition.
Throughout the day, the students had an opportunity to “showcase their engineering might” by competing in a wide array of science, technology, engineering and mathematics (STEM) challenges. Events included Bio Bowl, Math Quest and a STEM spirit video challenge, as well as contests to build bridges, prosthetic arms, straw towers and wind-energy devices.
“All of the students did an excellent job,” says Paul Rakowski, director of student services for the CU Denver College of Engineering and Applied Science. “I’m always impressed by the caliber of students this event draws and how excited they are to learn about STEM.”
Rakowski was one of many people who volunteered their time to judge the various events.
