Dr. Robert Orsillo, Optometric Physician for the Florida State University athletic program, wanted an objective way to measure his vision training techniques and turned to the Diopsys® NOVA-VEP Vision Testing System for help. As many athletes and coaches know, speed and accuracy are essential for success on the field which is why strength and endurance training is built into practice drills. But what if an athlete could get vision training to help see the ball sooner, or identify his opponent faster? That is exactly the training Dr. Orsillo provides athletes he works with, the opportunity to improve the speed of their vision system.

A recent clinical poster was presented at the Association for Research in Vision and Ophthalmology (ARVO) detailing Dr. Orsillo’s method for measuring his vision training. The poster, “Quantifying the Impact of Vision Training using Short Duration Transient Visual Evoked Potential (SD-tVEP),” states that the vision training drills were designed with the goal of improving the span and speed of visual recognition. The Diopsys® NOVA-VEP Vision Testing System was used to verify whether those goals were met.

The Diopsys® NOVA-VEP uses the science of Visual Evoked Potential (VEP) to objectively measure the function of the vision system, from the eye to the visual cortex, the vision center of the brain. VEP results consist of amplitude and latency measurements, which give the eye doctor an idea of how much information is being received by the brain (amplitude) and how fast it takes to get there (latency).

“In order to objectively gauge whether my vision training was working, my staff took baseline Diopsys® NOVA-VEP measurements before the vision training began,” said Dr. Orsillo. “After eight weeks of training, the athletes were again tested with the VEP system giving us a before and after picture of how the athletes’ vision system was functioning.”

Specifically, the athletes’ vision was tested using both a low contrast (dark grey and light grey) and high contrast (black and white) checkerboard pattern to elicit the VEP response. The results from the program were impressive. For the low contrast results, 48% of the athlete’s showed a reduction in latency in one eye, while 52% had a reduction in both eyes. At high contrast, 22% had a latency reduction in one eye, while 66% had a reduction in both eyes. This means that the vision system was sending visual messages to the brain faster than before the training.
