Our Approach

How Can We Help You Or Your Loved One?

Redefining Levels of Care


Traditional optometrists answer the questions, “Can you see clearly?” and “Are your eyes healthy?” but eyesight is only one small part of vision. At the Mind-Eye Institute we treat beyond that because some patients need a more comprehensive evaluation of symptoms that might seem unrelated to the eyes.

To that end, we provide 2 distinct levels of care:

1. Developing Mind-Eye Connections:

– Can you efficiently see with ease and comfort?
– Are you effectively using your visual system?

2. Redeveloping Mind-Eye Connections:

– Are the systems connected with your eyes correctly synchronized?

Each person is unique due to differences in genetics, experiences and mind and body control. In fact, it is important to realize that there are crucial links between the body, environment and the mind which determine personality traits.

Even gifted people may have discrepancies among those connections. They may have an over developed mind, but lack social skills (environmental awareness), or they may be gifted in sports (body control) and be poor at academics, etc. Gifted leadership skills are just as important as gifted music and art skills.

At The Mind-Eye Institute we take an individualized approach to every single one of our patients. Each one of our doctors' skills complement each other, allowing our practice to offer a broad spectrum of services for a variety of populations with various backgrounds. Below is a brief overview of the approach taken by our practice in all these different areas.

Take The 60 Second Mind•Eye Symptoms Assessment

1. Developing Mind-Eye Connections

Sensory Processing Assessments

Beyond the traditional eye examination, the Mind-Eye Institute provides Visual Processing Evaluations which determine whether you efficiently see with ease and comfort.  This level of evaluation includes specific testing for ranges of comfort in eye aiming, focusing, eye teaming and evaluates your awareness of and interaction with your environment.

This is helpful for people who have trouble gathering and processing incoming information, for instance those who are lacking in social skills or organization. Typically, patients that would benefit from this kind of evaluation are labeled to exhibit learning difficulties. Symptoms include not being able to easily transition from one situation to another or not being able to visualize concepts while keeping the details in mind. The most common sign observed is avoidance (i.e. avoiding driving, essay writing, reading or sports, etc.)


2. Redeveloping Mind-Eye Connections

Neuro-Developmental Assessments

When conventional eyeglasses are not beneficial, other systems must be considered. Are the systems connected with your eyes corrected synchronized? Here, the linkage among posture, auditory and biochemical systems are analyzed, all which influence eye control and usage.

This level of testing is beneficial for people who have delicately balanced visual systems, where minimal environmental changes are annoying. People who have difficulty in coordination, maintaining attention, or have a delay in development often benefit from this extensive battery of testing which gets to a root cause of a problem, rather than simply addressing symptoms.


Our Research & Expertise

Autism and Developmental Deficiencies

For almost thirty years, the Mind-Eye Institute has served patients from national and international locations, assessing peripheral eyesight usage in addition to central (20/20) eyesight. Children with special needs or those on the autistic spectrum, benefit from having Mind-Eye eyeglass prescriptions, which help ensure brain signals are being processed efficiently in a synchronized manner. For instance, eyeglass prescriptions determined by using our patented Z-Bell testing help regulate eye-ear connections. Those Z-Bell prescriptions enhance patients' reading, listening and attention in a majority of cases. The individualized glasses create a stable balance between central and peripheral eyesight, as well as auditory and visual localization ability.

Post-Concussion &
Traumatic Brain Injury Exams

Many people suffer from various post-concussive and brain injury symptoms such as photophobia, ocular fatigue, headaches, dizziness, and sleep problems and mood changes. We understand that interactions between the electrical and biochemical pathways in the brain affect physical, physiological and psychological systems. Patients undergo a thorough examination with advanced technology and testing techniques to measure visual performance and visual processing functions. The goal is to determine whether the visual processing systems are in balance with other sensory systems that require perception of space and time, such as auditory localization ability.

A Different Approach to
Learning Difficulties, ADD/ADHD

At our practice, developmental examinations cover much more than how well a patient can see. For example, a child who is diagnosed with ADD, ADHD, CAPD, or developmental delays, may in fact be experiencing these symptoms as a results at least in part because of visual systems dysfunctions. It is important to realize that eyesight is only one small part of the visual system; there are many other visual inputs often not addressed during routine eye exams. Each of the systems develop in a hierarchy, linking with other systems' development. For instance, motor skills and visual skills combine for good hand-eye coordination, or visual and auditory skills combine for reading.


At the Mind-Eye Institute

We understand that interactions between the electrical and biochemical pathways in the brain affect physical, physiological and psychological systems. Visual interventions that alter retinal signaling pathways impact both the electrical and biochemical systems.

Our patients undergo thorough examination with advanced technology and testing techniques to measure their reactions and responses to light entering the retina. With this information, experts at the Mind-Eye Institute determine whether a patient’s visual and auditory systems are synchronized. They consider how light might be manipulated to positively impact brain function and body chemistry. The goal is to find optimal ways of mitigating symptoms that are not improved or resolved through standard approaches.

Specifically, our team offers patients prescriptive eyeglasses, contact lenses or other optometric interventions to selectively stimulate light dispersed on the retina. Individualized lenses can:


  • Maximize patients’ visual performance and visual processing capabilities and create a stable balance between hearing and visual localization.
  • Improve patient perception of the surrounding environment in order to modify behavior and enhance communication skills.
  • Help rebuild brain pathways or develop new pathways that enhance a patient’s ability to learn, understand and interact normally with others.

'Dr. Zelinsky Is Renowned'

~ Norman Doidge, M.D. & Clark Elliott, Ph.D., Dr. Patrick Quaid 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 Vanderbilt University found that children with autism do not synchronize their seeing and hearing...I have watched Dr. Zelinsky administer this test to disbelieving colleagues, 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."

- Norman Doidge, M.D.

"I was delighted to have Dr. Zelinsky personally contribute to the book. Her wealth of knowledge in the area of visual development and visual processing is widely known, not just through her contribution of eye-care to the author of “The Ghost in My Brain”, but also via her Mind-Eye Institute and the lectures and training their provide. Dr. Zelinsky is not just colleague and a friend, but also a valued member of the neuro-optometric community and an invaluable bridge to other allied professions treating brain injuries. Her contribution to the book is deeply appreciated."

- Dr. Patrick Quaid, MCOptom, FCOVD, PhD
