RevitalVision uses a series of grouped Gabor patches presented in succession at specific, individually designed frequencies, spatial arrangements, contrast levels, orientations and exposure durations to stimulate the visual centers within the cortex. 1,2 It relies on the visual and cortical impact of Gabor patches, which are sinusoidal gratings located within a Gaussian envelope that are often used as psychophysical stimuli. The science behind Revital-Vision is quite intriguing and dates back more than 20 years. Instead, this technology employs computer-based, neural visual therapy (NVT) in an attempt to improve functional visual performance for patients who desire an alternative to spectacles or refractive surgery. Based in Lawrence, Kans., RevitalVision provides a unique product intended to enhance vision in a variety of conditions without the use of lenses, medications or surgery.

With that in mind, we were highly interested to learn of a new technology that seeks to address visual concerns with an unconventional approach––the Revital-Vision Training System. Nonetheless, these fundamental areas of vision care remain at the core of optometry and indeed represent a significant portion of our day-to-day activity in clinical practice. Over time, ocular conditions that typically are managed with lenses and prisms have become dissociated from those that are treated with medications.

Generally, we have steered clear of visual disorders like amblyopia, myopia and presbyopia in this column––frankly, because most optometrists no longer consider these areas to be within the realm of therapeutics. Typically, we discuss a particular pathological entity, such as macular degeneration or bacterial keratitis, and the current or emerging therapies available to combat the given condition.

The goal of “Therapeutic Review” always has been to enhance our colleagues’ understanding of ocular disorders and their clinical management.
