2007 Third Edition Forward 

(Online Publishing Version )


 Since the first edition of Window of Health ---- Ocular diagnosis and Periocular Acupuncture was published in 1996, I have worked very hard to introduce this unique micro-acupuncture technique to my colleagues. I have taught this subject for continued education in many Acupuncture schools in United States. I was happy to see there were hundreds of acupuncturists have attended the classes. I have received very positive evaluation in majority returns. I wish all the acupuncturists who have studied this technique could have received benefits in their practices. Special their patients have recovered sooner and fuller through this unique acupuncture treatments.


I continue to apply this technique in my clinical practice for the last fourteen years since I learnt from Professor Peng Jingshan’s Ocular Therapy Department in Liaoning College of Traditional Medicine in 1993. I observed each new patient’s eyes as one part of my routine TCM exam. If I found the change on the capillary branches of the bulbar conjunctiva. I would insert a needle on that corresponding peri-ocular acuzone. In my experience, it helped to relieve the patient’s symptom as I expected. Through these years, I believe this technique works well for the stroke patient whose onset within six months. It is also beneficial to internal disorders and acute pain relief. It effects wonderful on many eye diseases. If patient does not have treatment daily, I suggest to use this technique applying in association with other therapeutic methods to obtain a sooner result.


Special thanks to Dr. Ralph Wilson, a naturopath physician and a master of acupuncture, he wrote the endorsement and home care tips for this version and putting up this book to online publishing. It can be purchased from . I wish some day when more acupuncturists and other medical practitioners see the benefits of ocular diagnosis and peri-ocular acupuncture for their patients and feel comfortable using this technique in their practices. I look forward to have a conference for discussing and sharing the experience of using this unique method will be held in United States.

I highly recommend Dr. Hoy Ping Yee Chan’s text Window of Health ---- Ocular diagnosis and Periocular Acupuncture. She has worked diligently to present the micro-acupuncture system that was discovered by Professor Peng Jingshan after his careful observations of patients over many years. Reading the story of Professor Peng Jingshan impressed me deeply because of his dedication to the true application of scientific observation of the human body. His work and that of Dr. Chan will be very important, I am certain, in helping to advance world understanding of human health and how to assist the body to use its energies for healing. I am glad that I was able to help rescue the book and arrange to have it published online after the original publisher went out of business and the original was lost. This book will be a treasure of information for acupuncturists and also for health care professionals and even for the general public who want to know how enjoy better health.


I received my doctorate in naturopathic medicine from Bastyr University and then my masters degree in Acupuncture. I was privileged to study acupuncture in China in 1993.      I have continued to gather more knowledge about the energies of life and how to help people become more healthy. I had the honor of meeting Björn Nordenström, M.D., whose book Biologically Closed Electric Circuits was recognized by doctors in China as a breakthrough in understanding the electrical and electromagnetic aspects of the human being. I have been examining the works of Samuel Hahnemann, M.D., who discovered the energy medicine called “homeopathy,” that can cause changes in the pulse testing done in Traditional Chinese Medicine. I have trained with Dietrich Klinghardt, M.D., Ph.D., who studied acupuncture and homeopathy as well as western medicine and who has created a very effective system that integrates aspects of each of these respected approaches to improving human health. I have studied Craniosacral Therapy as taught by John Upledger, D.O.; he also teaches people about the value of acupuncture knowledge. I have been a member of the International Iridology Practitioners Association and have been involved in research to scientifically study the relationship of the fibers of the iris of the eye to the health of the person; there is evidence that areas in the eye are related to organ systems of Traditional Chinese Medicine. All of this and more helped me to decide to begin a teaching site on the Internet so that you can visit that site for more details. *


Through the millennia doctors in China have studied and preserved knowledge that is only now being more deeply appreciated by doctors and the public in the western world. I will be grateful to show this important book to not only acupuncturists and doctors and students of health care sciences but also to my patients. This is because of the importance of learning about the science of the acupuncture meridians and the energies of life.


Home care tips and resources for learning more are at the end of this book.


May this book help you learn much important knowledge!

Resources for Learning More


This section was prepared by Dr. Ralph Wilson,

who is responsible for its content.


I am grateful for the opportunity to help Dr. Chan make her book available again. The world is very much in need of such important findings as she and Professor Peng Jingshang have been teaching. Many professionals in the field of health care are becoming convinced of the benefits of including treatments that support the energies of the body when they help people with their health concerns. As I spoke about in the Endorsement at the front of this book, there are several methods of studying the human body and the energies that keep us healthy. The world will benefit a great deal when more is learned about how people can choose from a variety of treatments in what is now called Integrative Medicine.

The reader is encouraged to study the science of Acupuncture with its description of energy flow throughout the body. In this book Dr. Chan has made available many excellent pictures and explanations about using observation and stimulation of acupuncture points to help improve health of the eye and the body. Chapter IX: Periocular Self Care gives several suggestions for people to consider; supplies for these techniques may be available at one of the acupuncture supplies companies available on the Internet.


This book can be a very helpful starting place for those who are new to acupuncture theory and who are dedicated to learning more about what it can mean to their health. There are also many other additional resources for learning about health and acupuncture and this is encouraged. These include good books, internet sites with information, and schools that teach acupuncture and methods of understanding how to use energies, physical substances such as herbs and foods, and physical therapies such as massage, Tui Na, structural manipulation of the body, and exercises to help improve health. Following the information about the Chinese Eye Exercises I introduce the study of the iris of the eyes, called Iridology, and describe how this seems to be similar to acupuncture microcircuits that Dr. Peng and Dr. Chan teach.


Please also understand that this book and resources are not intended to serve as diagnosis or treatment for any disease. For any health concern please consult a health care professional.

Iridology Information


Extra information about the eyes:

Iris Analysis -- also known as Iridology


One of the important contributions of the work of Professor Peng Jingshan and Dr. Hoy Ping Yee Chan is that it draws attention to the eyes and what can be learned by studying this area of the body. This book, Window of Health ---- Ocular diagnosis and Periocular Acupuncture, gives definite evidence that the eyes and the tissues around them reveal the results of healthy or unhealthy flow of energies within the body. The study of the iris of the eye, most commonly known as “Iridology,” is another way to learn about the condition of other parts of the body.


In the last century many doctors in China learned about iridology from Dr. Bernard Jensen, D.C., N.D. Dr. Jensen had studied earlier writings about iris structure and human health and then he developed charts of the iris structure and organs in the body that have been associated with different locations in the iris. His iridology chart has been translated into Chinese; readers of this book may have seen one of his charts either in English or Chinese. His work might be described as showing “microcircuits” that are similar to those diagrammed by Professor Peng; the iridology charts also remind me of Chinese drawings of microcircuits in the ear. Other authors who have written about iridology come from many countries (Germany, Russia, Korea, Japan, Canada and England as well as the United States), and there is much information available on the Internet.


Physical Findings with Iridology: On the previous page are pictures from the Canadian Neuro-Optic Research Institute (CNRI). These include: (Top) photographs of eyes, with the arrow pointing toward a whitish “ripple” that reportedly is caused by increased tension in the Autonomic Nervous System resulting in shortening of the length of the fibers in that part of the iris; (Middle) this shows a superimposed grid that was created by a computer program that is used by CNRI to more accurately study the iris in individual patients; (Bottom) this is the Integrative Iridology Chart by CNRI founder, Prof. Bryan Marcia, Ph.D. The CNRI offers a selection of books, videos, charts and digital iris cameras called Iriscopes.


Neuro-Emotional Findings with Iridology: Examination of the full-size charts of the iris of the eyes, both the one by Dr. Jensen and the one by Prof. Marcia, will reveal the location of areas in the iris and the name of the corresponding tissue or organ in the body. This “microcircuit” of body energy flow reminds me of the larger acupuncture meridians that are described in Traditional Chinese Medicine and that are illustrated in this book. For thousands of years Chinese doctors have recognized that the energies flowing through the meridians of the body affect all the functions of the human being. I find it very interesting that TCM lists different emotions associated with the different organ systems. For example, the Heart Meridian is associated with Joy, the Kidney Meridian is associated with Fear, and the Lung Meridian is associated with Grief. The association of emotions with organs becomes important when examining the iris of the eye. I am very happy to have discovered the clinical findings of Denny Johnson, as described in his book, What the Eye Reveals. He founded the Rayid system of emotional iridology. It seems clear to me that his descriptions of the emotions related to areas of the iris demonstrate the same type of associations that are made in TCM between emotions and organs. This is a subject that I hope will receive much research in the future. You are encouraged to read that book.


Iridology Professional Association: In the past I have been certified as a member of the National Iridology Research Association. This organization has expanded its reach worldwide and is now called the International Iridology Practitioners Association (IIPA). The Mission Statement of IIPA: The International Iridology Practitioners Association was founded for the purpose of increasing and diffusing knowledge concerning the art and science of Iridology and to provide a forum for the exchange of information and research with the goal of promoting excellence in international Iridology standards. The IIPA offers annual symposia about Iridology, and has a Research Director to help foster scientific study of Iridology.


Final note about Acupuncture and the energies of the body: It is my hope that there will be continued scientific interest in studying the various microcircuits in the body. The work of Prof. Peng and Dr. Chan demonstrates how important these microcircuits can be to help people improve their health. As I said in the Endorsement, I was privileged to meet Björn Nordenström, M.D., whose book Biologically Closed Electric Circuits was well received in China. His research was conducted at the Karolinska Institute in Sweden (this is the organization that awards the Nobel Prizes); he demonstrated that there is a difference in the electrical charge in the arteries compared to the veins. This means that there is a flow of ions through the blood vessels, and by the laws of physics this generates electromagnetic fields around the blood vessels. I think that his discovery is as important as discovering that the Earth revolves around the Sun.


The fact that the body has a complex network of electromagnetic fields will slowly change the way that doctors think of the body and also change the way we learn to live in healthy ways regarding electromagnetic fields around us. Dr. Nordenström’s work can be used to explain how acupuncture meridians exist. As I describe on my teaching website in the Acumeridian Science section, I suspect that these electromagnetic fields are responsible for holding the thick viscous fluid Hyaluronic Acid (or “hyaluronan”) in place so that it acts as tubules that protect an inner fluid matrix that carries the energy known as Qi. Many research articles found on the Internet are related to Hyaluronic Acid and acupuncture. I am impressed by the success that Dr. Nordenström had in treating cancers by altering the electrical charge in them and in the tissues around the cancers. It has only been two decades since his very important research was announced to the world. I expect that there will be continued gain of new knowledge as researchers and clinical practitioners apply this important information to the task of helping people improve the energies in their bodies. [Note: Recently a video of Dr. Nordenström, titled “Biologically Closed Electric Circuits” was placed on; this describes his discovery and how he found support in China for this important work.]


The Resources listed next are only a small number of the resources that could have been listed. I list many more on my teaching website, and you can find many more on the Internet using a search engine.
