Mind-Eye RESEARCH:

 Overlooked Effects of Ambient Lighting on Metabolism and Cardiovascular Disease 

by Deborah G Zelinsky, OD

2011 International Conference on: 
Clinical Research: Dermatology, Ophthalmology and Cardiology 

Abstract
Research has demonstrated that contributing factors to the incidence of cardiovascular events can be extrinsic or intrinsic. Exogenous stimulants include sleep deprivation, volume of caloric intake and ambient room temperature, among others. Endogenous factors, leading to changes in gene expression affecting the heart and vasculature, include humoral, autonomic and light/dark mechanisms. Emerging evidence documents effects on myocardium, measured by numerous risk markers of cardiovascular disease. Many of those risk markers are regulated by the circadian system — endogenously generated, but still susceptible to external stimuli. Alteration of the circadian rhythm by ambient lighting changes will affect sensory input to non-visual retinal pathways, such as the one leading to the suprachiasmatic nucleus, master regulator of circadian functions. Purposeful stimulation of the retino-hypothalamic tract and other retinal pathways elicits chemical changes in the optic nerve, triggering quantifiable shifts in metabolic activity in the brain and body, such as melatonin levels. A novel approach to preventive and therapeutic cardiovascular health is the intentional activation of nonvisual retinal pathways, by using specific frequencies of ambient lighting during carefully selected times in either home or institutional settings. Future investigation may shed light on possible correlations between light exposure during sleep and arrhythmogenesis or sudden death.

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.”

“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.”
