I worked on this project as part of a Johns Hopkins BME Design team when I was a freshman in college.
Our team tried to come up with a novel device to allow for fast and automated fundus imaging in a non-mydriatic manner. The application in mind was to diagnose of glaucoma cheaply and quickly at rural areas in developing countries.
A provisional patent for this work has been filed. You can find the patent here.
P.S. You will see my name on the patent filing as “Eric Tam”…apparently somebody (probably from the JHU Tech Transfer Office) misspelled my name. (Yes, people misspell my name a lot. Yes, I have emailed the tech transfer office about it. No, there is not much that we could do to modify it at this point…)
