Quantitative Electroencephalograms and Neuro-Optometry 

by Deborah G Zelinsky, OD & Corey Feinberg

A Case Study That Explores Changes in Electrophysiology While Wearing Therapeutic Eyeglasses 

Abstract. The brain is equipped with a complex system for processing sensory information, including retinal circuitry comprising part of the central nervous system. Retinal stimulation can influence brain function via cus- tomized eyeglasses at both subcortical and cortical levels. We investigated cortical effects from wearing thera- peutic eyeglasses, hypothesizing that they can create measureable changes in electroencephalogram (EEG) tracings.

A Z-Bell® test was performed on a participant to select optimal lenses. An EEG measurement was recorded before and after the participant wore the eyeglasses. Equivalent quantitative electroencephalography (QEEG) analyses (statistical analysis on raw EEG recordings) were performed and compared with baseline findings. With glasses on, the participant’s readings were found to be closer to the normed database. The original objective of our investigation was met, and additional findings were revealed. The Z-bell® test identified lenses to influence neurotypical brain activity, supporting the paradigm that eyeglasses can be utilized as a therapeutic intervention.

Also, EEG analysis demonstrated that encephalographic techniques can be used to identify channels through which neuro-optomertric treatments work. This case study’s preliminary exploration illustrates the potential role of QEEG analysis and EEG-derived brain imaging in neuro-optometric research endeavors to affect brain function. 

Make The Connection

‘Dr. Zelinsky Is Renowned'

~ Norman Doidge, M.D. & Clark Elliott, Ph.D., and Patricia S. Lemer praise her accomplishments

“Zelinsky fit Elliott with a series of eyeglasses designed to improve the perceptual damage that made his life so difficult… Getting fitted for Zelinsky's eyeglasses is like no eye appointment you've ever had… Now, Elliott says, he is almost entirely symptom-free, able to problem-solve, multi-task and find his way easily — all abilities he lost in the auto accident in 1999. When he put on his Phase VI glasses he felt something that he hadn't felt for years: “I felt normal.”

Review: ‘The Ghost in My Brain'
– The Chicago Tribune

“One brilliant Chicago-area optometrist I know, Deborah Zelinsky OD, FNORA, FCOVD, has developed a unique, patented, easy-to-administer evaluation called the Z-Bell Test. This test measures the efficiency of integration between visual processing and listening….A 2014 study at Vendarbilt University found that children with autism do not synchronize their seeing and hearing…I have watched Dr. Zelinsky administer this test to disbelieving coleagues, who were astounded by its accuracy and results…Over the past two decades, the Z-Bell Test has become internationally recognized by the scientific community.”
– Patricia S. Lemer, Licensed Profesional Counselor (LPC)

“I visited Dr. Zelinsky, and she showed me how she can use optical lenses to alter sensory filtering, by directing light to different retinal cells and brain circuits. This can influence activity in the brain and the hypothalamus to better regulate body chemistry, sensory integration, and even some auditory processing. [Dr. Zelinsky] works frequently with patients working with learning and cognitive disorders as well as TBIs.”
