AAOSA/OSUM Seminar: “Frontiers in Eye Laser Therapies”

Yannis M. Paulus, MD
W. K. Kellogg Eye Center

Tuesday October 10th, 6:30 p.m.

Location of Seminar: Room 1123 Lurie Biomedical Engineering Building (LBME), 1101 BEAL AVE, Ann Arbor, MI

Abstract
In 1961, one year after the first laser was developed, laser therapy of the eye was described. For over 55 years, laser therapies have played a critical role in the treatment of numerous eye diseases, including proliferative diabetic retinopathy, diabetic macular edema, retinal vein occlusions, sickle cell retinopathy, tumors, retinal tears, glaucoma, and secondary capsule opacification cataracts. Significant advances have been made in laser technology and the molecular understanding of laser–tissue interactions to maximize the therapeutic effect while minimizing side-effects. We will discuss conventional panretinal photocoagulation and focal laser therapy in addition to new and emerging technologies, including: patterned scanning laser, selective retinal therapy, subthreshold micropulse laser, nanosecond pulse duration laser, photo-mediated ultrasound therapy, navigated laser, and real-time image-guided laser therapy. Selective and shorter pulse duration therapy can significantly reduce the collateral damage, patient pain, and complication risk while increasing the therapeutic effect and safety window. Continuing innovations in laser technology and progress in understanding laser-tissue interactions mean that lasers will continue to play a critical role in treating eye diseases for many years to come.

AAOSA/OSUM Seminar: “Compton Composites – A New (and mostly hidden) State of Matter”

Thursday September 14, 2017 at 6:30 p.m.

Frederick J. Mayer, Ph.D.
Mayer Applied Research, Inc.

Location of Seminar: 1123 Lurie Biomedical Engineering Building (LBME), 1101 BEAL AVE, Ann Arbor, MI

Abstract
Over the past few decades, paradoxes have arisen that suggested we have missed configurations of otherwise basic particles (electrons and protons) that are different from, but in some ways similar to, ordinary atoms. I will discuss how this question started the search that evolved into an understanding of such a configuration at the electron Compton wavelength scale and why it has mostly been “hidden” from observations. The new Compton composites connect a number of research areas including cosmology, the solar corona, and geophysics.

AAOSA Seminar: “The Birth and Amazing Life of Nonlinear Optics”

Abstract
The birth of the field of nonlinear optics occurred in Randall Laboratory at the University of Michigan in 1961 when Franken, Hill, Peters, and Weinreich observed for the first time the generation of optical harmonics.  By illuminating a crystal of quartz with an intense infrared beam at 694.3 nm from a ruby laser they were able to generate the second harmonic at 347.15 nm.  This discovery was rapidly followed by the observation of numerous other effects such as optical rectification, frequency mixing, third harmonic generation, self-focusing, and parametric oscillation, all within the space of about four years.  In this talk we review the birth, growth, and modern day applications of nonlinear optics.  We will also take the opportunity to plug the OSA Conference on Nonlinear Optics, July 17-21, 2017, in Hawaii:
