Device for measuring visual field in compromised patients

Patients suspected of having glaucoma must undergo a subjective test that measures central and peripheral vision. During this test, they are instructed to rest their chin on a stand while looking straight ahead into the device. Lights flash on and off at different positions in the device, and the patient presses a button when they see a light. However, this test is subjective, which often skews the results. For example, some patients try to compensate for their inability to see the flashing lights by excessively pressing the clicker. However, this causes inaccurate results.  The test can also be taxing for the patient. Since glaucoma patients are often 40 or older, it can be difficult for them to complete a 10-20 minute test that requires continuous concentration. Some even fall asleep during the test. Visual field tests are also difficult to administer, and the results are difficult to interpret. Patients who have taken the test many times often score better, resulting in a false improvement in vision. Because current methods of visual field testing are both inaccurate and taxing, a simpler, faster, and more objective test is needed.

Halma, the company we are working with, has already generated both software and hardware prototypes for a device that accomplishes this. However, these models cannot be easily manufactured or used beyond a research setting. The purpose of our project is to make Halma’s prototypes useable outside the research space and make the device scalable for mass production. We aim to improve the functionality and aesthetics of the device while ensuring that it will be able to pass through the filters of marketability, profitability, and federal regulations. In the future, this device could not only be applied to the evaluation of ocular health, but also to the evaluation of neurological health. By assisting Halma with the marketability of their current product, we hope to help make it possible for them to bring this idea into reality.
