Fall 2012
President’s Message: Dr. Kristal Kawamoto Hello AAOS family! Yet another summer has come and gone. Hopefully everyone was able to squeeze in some R&R, vacations, or at least a trip to the beach. Our May Honor’s Banquet was another wonderful event, held again at McCormick & Schmick’s in Anaheim’s Garden Walk. Dr. Kristie Lin was so gracious to provide us with her knowledge on stem cell therapy for AMD. After a nice lunch, students arrived for the panel of doctors Q&A session. In July, many of you joined us again in Anaheim for the Angels vs. Rangers
baseball game. Tickets were complimentary to all AAOS members, as each $10 ticket was provided with a $10 food voucher. Many students were able to attend this event as well. A much needed study break! Don’t forget to mark your calendars for our Fall CE, taking place again at the Cerritos Sheraton hotel on Sunday, September 16th. A great line-up of doctors will be speaking to help you tackle those CE hours. One change we will be making is the addition of a “promptness raffle”, held promptly at 8am. Get there on
time for your chance at a great prize! Of course, none of this would be possible without our generous sponsors! Be sure to visit them at the CE during the breaks. As always, don’t hesitate to give comments or suggestions on how we can make your society even better! See you soon! -Kristal Kawamoto

Dr. Connie Liu Recaps the AAOS Angels Baseball Event! Hi EveryoneWe just wanted to thank all those members and students who were able to attend our 2nd annual Angels game event on Sunday, July 22nd. Luckily for us, the game was moved to 5:00 pm, so no one's views were obstructed by umbrellas and no one got sunburned! Also, it never hurts when the home team wins the game. It's been awhile since I've actually attended a baseball game, so I just wanted to share a few things I
learned that night: 1) Apparently the Angels have a thing for fishes- first Salmon, and now Trout. 2) Remember where you parked your car, because you can be walking for quite awhile...and if you get lost long enough, you can actually see the player's leave the player's exit (although, with tinted windows, you can only speculate who was in that car). 3) You can never go wrong with a hot dog in a ballpark.
Dr. Kenny Fukuda and his wife, Jeanette recently celebrated their son Trevor’s first birthday! He is pictured here together with his sister Maddy who is 9 years old. Happy Birthday Trevor !
Overall, it was a great game to attend and catch up with our fellow members. If you have any ideas for any future events, please let us know. We've already heard a few suggestions on how to improve the event, and we look forward to implementing them in the future.

2012 May Honors Banquet Greetings AAOS members! Our May Honors Banquet and CE held Sunday, May 20, 2012 at McCormick and Schmick’s at the Anaheim Garden Walk was a tremendous success. We had about 40 doctors and students attend the event. Thank you to Dr. Kristie Lin from the Retina Institute of California for her lecture on advances in retinal therapy. Every spring our society gives out scholarships to deserving 4th year students at the Southern California College of Optometry. The recipients of this year’s awards were: The Dr. Arthur Sugino Memorial Scholarship: Silvia Han The Dr. William Yamamoto Memorial Scholarship: Jennifer Tran
I would like to also congratulate the entire graduating class of 2012 from SCCO. It is a tremendous accomplishment to complete your doctor of optometry and we all look forward to having you join us as peers. The banquet also featured a panel of doctors from all of the various modes of practice in optometry. On the panel we had Dr. Raymond Maeda for faculty/academics (Western University of Health Sciences), Dr. David Tanouye representing industry (ReVision Optics), Dr. Larry Macapagal for managed care (Kaiser), Dr. Stacey Gin for private practice, Dr. Michael Ontingco for military (Navy), Dr. Tony Dang for ophthalmology, and Dr. Diana Ciobanu representing corporate optometry (Luxottica). The panel was a tremen-
dous success as all of the students got to answer any questions they may have had as they start to enter the work force and to hear about all of the different modes of practice. Thank you to the panel of doctors for your insight and for taking the time to answer all of student’s questions. The day ended with our raffle of various prizes such as movie tickets, restaurant gift cards, and an ipod touch. Looking ahead to the future please make sure to be on the lookout for an announcement of the date and location of our installation banquet for 2013. -Jeff Nishi

The Optical Coherence Tomography Revolution Alexander Walsh. MD In the two decades since it was invented, optical coherence tomography (OCT) has revolutionized the field of ophthalmology by providing unprecedented cross-sectional imaging of transparent tissues in the eye.1 Like ultrasound, OCT produces images by measuring the strength and elapsed time of reflected signals. Unlike ultrasound, OCT uses light. This enables OCT to be non-contact, penetrate deeply into clear or translucent media, and image tissues with micron resolution. However, since the speed of light is nearly one million times faster than sound, OCT cannot use standard detection methods to measure the time it takes light to reflect off of the retina. Instead, OCT uses low-coherence interferometry which measures pico-second differences in time through the destructive interference of combined light waves.
A Brief History The first type of OCT to reach the clinical realm was time domain OCT (TDOCT). In addition to providing unprecedented images of the retina and optic nerve, these instruments also made another revolutionary leap by automatically quantifying important tissue parameters such as thickness. However, TD-OCT was plagued by speed and resolution limitations that ultimately resulted in it being supplanted by a newer form of OCT, spectral domain OCT (SD-OCT). SD-OCT has at least three major advantages over TD-OCT. First, by replacing TD-OCT’s slow mechanical interferometer with a faster, stationary, spectrometer-based system, SD-OCT can capture data fifty to one hundred times faster than TD-OCT. This enables more complete tissue coverage and better image quality by averaging out noise. Second, SD-OCT is more sensitive than TD-OCT which allows better definition of subtle structures. Finally, since many of the principles of SD-OCT were published in the public domain before they were patented, several companies were able to enter the commercial SD-OCT marketplace. This competition drove SD-OCT research and development and controlled instrument costs better than in the era of TD-OCT when one company dominated device sales. The newest form of OCT, called swept source OCT (SS-OCT), replaces some of the expensive components of SD-OCT with a tunable light source made possible through recent advances in laser technology.2 These instruments have the potential to be five to ten times faster than SD-OCT, have higher sensitivity and better penetration of the choroid,3 and longer imaging ranges. In fact, it is now within the realm of possibility that future OCT systems may be able to image the entire eye and may succeed slit lamp biomicroscopes as the preferred method of examining the majority of tissues in the eye.
Applications OCT has found utility in most areas of eye care – including retina, glaucoma, anterior segment, and neuro-ophthalmology. However, the utilization of OCT is still far from its peak. Several areas of research offer exciting new potential for OCT in the field of eye care.
Adaptive Optics Using the same higher order aberration correction used in new forms of refractive surgery, adaptive optics OCT has the potential to greatly enhance the lateral resolution of OCT systems to enable near cellular level resolution.4,5
OCT Angiography Conventional OCT systems now can be used to precisely map the retinal and choroidal vasculature.6 Using Doppler principles, OCT can also be adapted to measure blood flow velocities in these vessels.7 This may have utility in assessing patients with glaucoma and retinal vascular diseases. Furthermore, using advanced analytics, future OCT systems may even be able to detect fluid shifts across vessel walls, thus enabling an era of non-invasive, OCTbased angiography.
Intraoperative OCT OCT systems integrated into operative microscopes have the potential to augment traditional surgical microscopy with OCT’s unprecedented crosssectional imaging.8,9 By allowing surgeons to better visualize and delineate minute structures within the eye, intraoperative OCT may make surgical procedures faster, less morbid and provide better outcomes.
Widefield OCT Just as widefield color imaging has been adopted as a method to analyze and document findings across nearly the entire fundus, widefield OCT may also play a role in understanding and documenting findings outside the arcades.10
Smart OCT Based on the versatility of software-driven applications, ‘smart’ OCT systems may be able to expand on the potential of OCT by using it both as a structural and functional imaging methodology. Like ATMs, automated, binocular OCT systems also have the potential to enable high quality, low cost comprehensive eye exams in remote locations at any hour of the day.
Conclusion OCT has forever changed the way that eye care providers examine the eye. Emerging OCT technologies are poised to continue this revolution by giving clinicians and surgeons even better tools to evaluate the eye and understand eye disease.
