DOHENY UPDATE | Summer 2017 | Page 5 A regular research subject is tilted to simulate the fluid shift that occurs in the microgravity of space. The challenge then is to acquire pictures of minute regions of the eye using optical coherence tomography (OCT), the best technology available for this purpose. Most ophthalmologists have modern OCT machines in their offices. A patient sits in a chair in front of the machine with his or her chin on a chin rest. In a matter of seconds, an image of the eye is complete and ready for examination. But here, the typical OCT machine can’t be used because of the tilted position of the subject—except by Dr. Huang because of a specially designed OCT extension arm that was built for him by Heidelberg Engineering for the aqueous angiography project Dr. Huang started. When NASA heard about Dr. Huang’s OCT upgrade, they immediately enlisted his collaboration. Not only did Dr. Huang have the right technology, but as a glaucoma expert he also had expertise on the effects of pressure on the optic nerve. Add to that his work with the Doheny Image Reading Center — where reading OCT images and research on OCT findings in the retina and optic nerve is their bread-and- butter—and it was a collaboration made in heaven, so to speak. Amazing. n The research subject is tilted to simulate the fluid shift that occurs in space. OCT images of the inside of the eye’s blood vessels are then gathered to study VIIP.
