  4. 4 WHAT IS SIGHT?
  5. 5 The EYES are the medium through which light from outside of the body can pass through in order for the BRAIN to see an image. It is through the structure of the eye that we can see the world around us. Not only does this VISUAL SYSTEM allow us to see images when we are awake and conscious, but it also serves to imprint images that are remembered for recall at any given moment including the time of SLEEP. SIGHT is, therefore, a function of the gatekeeper (EYE) which permits the entry of the guest (LIGHT) into the home (BRAIN) and the chemistry allows for a harmonious interplay (IMAGE) that will be imprinted indefinitely. There are many ways to literally look at sight, but for this discussion, we will focus on the sight that we use to view or everyday world.
  6. 6 WHAT ARE THE STEPS IN THE PROCESS OF SIGHT? 1) Light touches through a thin veil of tears that bathes the front of the eye. 2) This is the CORNEA that is curved (arced) and will refract or bend the light as it enters the eye. There are no blood vessels here. 3) The light projects through a small pool of AQUEOUS HUMOR that is clear watery fluid that keeps a constant pressure within the eye. 4) The pupil receives the light and the amount of light that actually enters the rear of the eye itself is controlled by the muscles of the colorful IRIS. 5) The LENS is the next part that takes the light and it is this part where light is focused. The lens changes its shape to focus on light reflecting from near or distant objects.
  7. 7
  8. 8 6) Focused light then passes through another watery fluid that is more of a jelly texture called the VITREOUS HUMOR 7) Light finally reaches the RETINA- the inner lining of the back of the eye; here is where there is a transduction or change of the light energy into signals that will move into the back of the brain; here is where we have a MACULA with its center called the FOVEA (a VERY SPECIAL PLACE) 8) The macula and fovea have cells that include RODS and CONES will pick up the light energy and send the energy into nerves out through the back of the eye. 9) The OPTIC NERVE is the nerve bundle that extends from the retinal cells via a special CHIASM to the back of the brain where SIGHT happens.
  9. 9 In order for all these magnificent processes to occur, there must be a rich BLOOD SUPPLY to the eyes, particularly to the retina. HOW CAN WE LOSE THE VISION? Many diseases and conditions can cause vision loss. The origin can be in the eye itself or caused by other conditions that affect the whole body.
  10. 10 EYE-RELATED CAUSES…  Age-related macular degeneration- there is loss of detail in the central vision  Cataracts- lens clouding that causes blurriness (most common cause as one ages)  Eye infection or inflammation- conjunctivitis or pink eye (temporary change of vision); retinitis or infection of retina; may be genetic  Eye tumor- retinoblastomas in childhood are seen in about 500-600 children each year in the US; melanomas in the eye are seen in about 1,200 adults a year.  Eye trauma- corneal abrasion  Glaucoma-progressive loss of vision with increased pressure buildup inside the eye; optic nerve is damaged; peripheral vision is first to go
  11. 11  Refractive errors such as myopia (nearsightedness) with the eye shape too elongated for lens so light isn’t focused properly on the retina; hyperopia (farsightedness) with the eye being “too short” for the lens, one cannot see up close; astigmatism (irregularly shaped cornea) that caused double vision  Strabismus- “crossed eyes” or eyes pointing in other directions; the brain can favor one eye and cause decreased vision in the other eye- this is called AMBLYOPIA or LAZY EYE  Presbyopia- “aging eye” in which lens hardens to reduce all focus  Detached retina- the retina becomes loosened from the blood vessels that nourish it with oxygen and nutrients. Seen in trauma and diabetes.  Retinitis pigmentosa- hereditary degeneration of the retina  Retinopathy of prematurity- abnormal development of the blood vessels of the eye due to prematurity of birth.
  12. 12  Congenital- may be a result of lack of formation of the visual system; intrauterine trauma or other diseases that can affect the fetal vision development such as rubella, syphilis, chicken pox, HIV, group B strep  Diabetes Mellitus- blood vessels are damaged; weakening of vessels may start leaking or overgrow the retina  Hypertension- high blood pressure that leads to narrowed vessels and reduced nutrients to the eye  Migraines-vision changes, phenomena, usually temporary but recurrent OTHER CAUSES OF VISION LOSS…
  13. 13  Multiple sclerosis- blindness in one eye that comes and goes due to central nervous system (brain) changes  Vasculitis- blood vessel inflammation  Down’s Syndrome- a significant number of these children have combined vision and hearing losses.  Medications or other medical/surgical related interventions- medications that can affect vision are numerous that include those for bladder incontinence, asthma/respiratory-related inhalers, steroids, plaquenil (used in rheumatoid diseases), anesthetics, cancer drugs and many more. Always be aware and check with the doctor/provider about this potential problem.
  14. 14 MORE SERIOUS OR LIFE-THREATENING CAUSES…  Head injury  Brian tumor  Increases pressure in the skull from trauma or bleeding  Stroke  Transient ischemic attack (TIA)- an early stroke or signal of impending stroke
  15. 15 There are many other conditions of the eye that can contribute to altered vision that is temporary or permanent. One condition called HYPHEMA is a commonly seen “bloody eyeball” that is usually not a serious issue. This is often seen with persons taking blood thinners who sneeze, cough or move suddenly causing a minor leak of the blood vessels between the cornea and pupil. It resolves within 1-2 weeks and needs no special treatment.
  16. 16 HOW DO WE HEAR?
  17. 17 Like the eye, the ear is a magnificent structure that is crafted so well it must have taken a true genius to make! The system is a complex organization of cells, hairs, nerves and tiny bones (the smallest in the body) that take sound energy and convert it into that which the brain can understand. As, stated above for the sight, the hearing that we will discuss is focused on that which we experience in normal daily activities and not that which enters the realm of hallucinations and such. Sound waves travel into the outer ear canal (where we have our wax buildup) then hit the tympanic membrane (eardrum) to cause a vibration. This vibratory movement is picked up by 3 tiny bones behind the eardrum (this is now the middle ear where fluid and infections commonly occur). The sound is then sent through semicircular canals into another bony structure called the COCHLEA.
  18. 18
  19. 19 The COCHLEA is the final place acting like a transducer that has fluid in it sending the sound energy to the cells that will cross into the COCHLEAR NERVE to the brain for interpretation of the sound. SOUND is recalled so that a voice, a note, a chirp or a blast is remembered and can be instantly brought into awareness at any time, just like in vision. BALANCE is controlled in the INNER EAR where the SEMICIRCULAR CANALS and COCHLEA are housed. The visual input along with the fluid and inner ear structures are all involved in the balance or imbalance that one experiences.
  20. 20 This is all controlled by a VESTIBULAR SYSTEM that consists of: WHAT ABOUT BALANCE OR LOSS OF IT? Semicircular canals, cochlea and other structures that pick up mechanical forces, sound, bone and joint positions. So when you spin or move your head from left to right, jump, swim, lie down or assume any position… YOU KNOW JUST WHERE YOU ARE in space AND YOUR BODY WILL DO ALL IT CAN TO RIGHT ITSELF OR KEEP THE HEAD FROM SPINNING!
  21. 21 Infections, head injuries, blood or lymph circulation problems, visual, skeletal, sinus issues, low blood pressure, low blood sugar, medications can all cause balance issues. If you have any of these problems, it is crucial that you look closely at your lifestyle to understand what you may be doing to contribute to this miserable condition. If it is a drug or a bad food diet that is present in your daily activities, you will need to make necessary changes for the reversal or amelioration of the problem. Do not just assume age is the major factor. BALANCE DISORDER…
  22. 22 Hearing losses can be the result of anything that disturbs the outer, middle, inner ear or auditory system directly to the brain. Birth defective hearing is not uncommon and can be associated with maternal illnesses or embryologic errors in the development of the hearing apparatus. Most often, hearing loss/impairment is ACQUIRED. It is via damage to nerve cells or hairs that the sense of audition is affected. About 50 million Americans have some form of hearing loss or damage. Many more people are yet to be diagnosed or even know that they have the problem ON HEARING LOSS…
  23. 23 RISK FACTORS/CAUSES FOR HEARING LOSS…
  24. 24 1) Heredity 2) Congenital or early childhood disease or exposures- a woman who develops rubella during pregnancy has risk for serious birth defects including hearing loss of the infant; mumps and measles can also potentially affect hearing 3) Noise- either recreational or occupational 4) Illnesses- high fevers, meningitis, severe ear or sinus infections 5) Meniere’s disease- affect 2.5 million Americans; an inner ear problem; fluid buildup in the inner ear; excess salt is associated 6) Ruptured eardrum- sudden change in pressures like a blast, a perforation by blunt trauma or a severe infection can cause a rupture and hearing impairment or complete loss.
  25. 25 7) Medications- like diuretics, e.g. furosemide, bumetanide, ethacrynic acid; others include gentamycin (antibiotic), high dose aspirin, anesthetics and chemotherapy. 8) Wax or cerumen buildup- ear checks by a health provider are important. Impacted was can be contributing to ones lack of or loss of hearing. It blocks the conduction of sound into the deeper ear structures. NOTE: it is not necessary to have the ear canal “squeaky clean” because some wax in the ear is protective against external entries of sound or particles. 9) Aging- cells get older, the ear structures can weaken, harden or have reduced blood circulation
  26. 26 SYMPTOMS OF HEARING LOSS… Difficulty understanding words Turning up volume on radio or TV Frequently asking people to speak louder Avoidance of social interaction and conversations among others
  27. 27 *Decibel levels (sound wave measurement) are measurable and the following is a list of levels and the ranges of safe, risk or injury to the ears: Decibel level/Source: *SAFE: 30- whisper 60-normal talk 70- washing machine *RISKY: 85-90- hair dryer, power lawn mower, heavy city traffic *CONTINUED RISK: 95- motorcycle 100-snowmobile, hand drill 110-chain saw, rock concert *INJURY: 120- ambulance siren 140- jet engine at takeoff (pain threshold) 165 12-gauge shotgun blast 180- rocket launch ON LOUDNESS AND WHAT IS ACCEPTABLE…
  28. 28 Decibel level/Duration 90- 8 hours; 92- 6 hours; 95- 4 hours; 97- 3 hours; 100- 2 hours; 102-1.5 hours; 105- 1 hour; 110- 30 minutes and 115- 15 minutes or less *(From the National Institute on Deafness and Other Communication Disorders, 2008; the National Institute for Occupational Safety and Heath, 2009; American Tinnitus Association; Department of Labor’s Occupational Safety & Health Administration, 2005 ) >>>>>So, if you are at a rock concert for more than 15 minutes, your ears are being violated by law!!!!!!
  29. 29 PREVENTION OF VISION AND HEARING LOSSES…
  30. 30 Avoidance of those elements that can create or set the stage for loss of both of these senses is most important. AWARENESS of your actions is essential in protecting those precious parts of the anatomy that provide us with complete connection to our world. While we cannot stop aging, we can make provisions and set up lifestyles that are most suitable or healthiest for the sake of preserving these organs. The following information has been selected as being probably the best in terms of alternative or natural approaches to the well-being and treatment of vision and hearing.
  31. 31 From a MACROBIOTIC POINT OF VIEW, dietary imbalance is the underlying cause of most eye problems. The need for eyeglasses, drugs and surgery can be reduced, controlled or sometimes avoided if measures are taken to change one’s habits for the betterment of the eye and the ear as well… In traditional Oriental Medicine, the eyes correspond with the liver whose MERIDIAN passes through the eye. LIVER IMBALANCES often translate into eye trouble.
  32. 32  Avoid food and beverage that stress the liver: meats, poultry in particular, refined grains, simple sugars like honey, white sugar, chocolate, ice cream, fruit juices, alcohol, stimulants, strong spices, excessive oil of any kind; chemically grown and treated foods  Eat whole grains, not floured  Use hardy leafy greens, orange and yellow veggies, kale, mustard greens, parsley, broccoli, pumpkins, Brussels sprouts and more  Use moderate salt (unrefined)  Moderate water- avoid excessive fluids, i.e. more than 60 ounces daily is more than enough for the average person not doing heavy work or athletics.  Use sea veggies on a daily basis- kelp, dulse, arame, nori, wakame, etc.  Reduce volume of food in a day; chew more RECOMMENDATIONS BY ORIENTAL MEDICINE for THE VISION:
  33. 33  Avoid late-night eating that burdens the liver and eyes  Do eye exercises including massage  May use sesame oil in very small quantities for eyes with the help of a clinician who will guide you on the drops to help remove excess fluid retention in the eye; do not do this without guidance.  A drink that is recommended to be helpful for the eye: combine 1 part dried shitake mushrooms, 1 part mung bean or soy sprouts, 1 part daikon greens, and 1 part buckwheat groats; add 4-5 times as much water and boil for 25 minutes to make a tea; drink 1-2 cups for 3 weeks and then every other day for 3 more weeks
  34. 34 THE FOLLOWING ARE RESULTS FROM MEDICAL SOURCES ON VISION IMPROVEMENT BY DIET: 1) Researchers from Brigham and Women’s Hospital in Boston reported that 1,380 people ages 40-79, who ate vitamin-rich vegetables, fruits and other nutritious foods had 37 % less risk of cataract development. (1) 2) In a Harvard study completed in 1995 with over 900 patients, researchers reported that people who had the highest intake of carotenoids, especially from dark green leafy vegetables like kale, collards, turnip and mustard greens, had a 43 % lower risk of MACULAR DEGENERATION.(2)
  35. 35 RECOMMENDATIONS BY ORIENTAL MEDICIANE FOR THE EARS:  The buildup of fat and mucus in the ear is the major cause of ear infections and hearing loss.  In traditional Oriental Medicine, the ear corresponds to the KIDNEY, which it shares a similar shape. Kidney problems as a rule lead to ear problems, while underlying hearing difficulties show urinary system imbalance.  Foods such as: meat, poultry, fish, eggs, cheese and other dairy, refines grains, sugary foods, fruits and fruit juices, spices, tropical foods, alcohol and drugs are considered major contributors.  COLD foods, in particular, contract the kidneys and contribute to hearing difficulties: ice cream, yogurt, soft drinks, iced beverages and other frozen foods.
  36. 36  Excess SALT is a contributor and is considered a major one for the condition known as MENIERE’S disease. Avoiding excess salt an fluids in both cooking and drinking.  Exposure to loud noises and other DISHARMONIOUS sounds are not good for the ears at all.  Reduce nut and seed butters until the condition improves.  Increase beans like lentils, chickpeas, adzuki beans and black soybeans, bean products like tempeh and tofu.  Avoid excess food, late night eating.  Avoid loud noises and you should always wear protective ear coverings if there is exposure that may not be avoidable.  Avoid using headphones, earbuds and all devices while jogging, exercising or just walking. These are all contributing to cell and hair damage in the delicate ear canals.
  37. 37  Do be aware of airport noises and have protective ear gear if you are working or dwelling in these areas.  Chew well.  Sing or hum happy tunes that will contribute to balance at many levels, directly stimulating the ears, kidneys, lungs, large intestines and other bodily organs and functions.  A drink that is recommended to help the ears: prepare a mixture of 1 part adzuki beans, 1 part dried daikon, 1 part shitake mushrooms, 1 part kombu (sea weed); add 5 times as much water, bring to boil and simmer for 25 minutes; take 1 cup daily for 7-10 days.
  38. 38  A hot towel compress or ginger compress around the ears will help melt fat and mucus deposits in the ear.  A ginger compress on the kidneys will have an energetic effect on the ears as well.  Wax buildup: several drops of warm sesame oil with an eyedropper; rinse with bancha twig tea with a pinch of salt added; DO NOT DO THIS WITHOUT GUIDANCE and understanding amounts and the temperature of the oil before instillation.  MASSAGE the sides of the head, tapping and vibrating all around the sides.
  39. 39 THE FOLLOWING ARE FROM MEDICAL SOURCES FOR THE IMPROVEMENT OF THE HEARING ABILITY: 1) In a West Virginia University of Medicine study in 1981, more than 1,400 persons were given plant-based diets with the avoidance of sugars, refines salts and other unnatural foods to see the effects on hearing. Here is what was quoted: “The response to dietary management is dramatic in most patients. With the otologic patient, dizziness clears promptly and the sensation of pressure in the ears is quickly relieved, along with associated headache. Hearing improves or stabilizes, evident in the pure tone audiogram and in the speech discrimination scores. Tinnitus often lessens in severity and sometimes even disappears…General health also greatly improves, and elevated blood pressure often returns to normal. The patients have more energy and are free from headaches, their arthritic symptoms improve, and they often sleep better.”(3)
  40. 40 2) Albert Tomatis, M.D., the “Einstein of Sound”, the world’s foremost authority on the ear and its functioning, recommends a diet that is centered on whole grains and fresh foods. He WARNS AGAINST eating processed foods, acid producing foods like dairy and yogurt, which he says can BLOCK THE EAR & THE DELICATE STRUCTURES AND PREVENT NORMAL HEARING. (4)
  41. 41 SOME OTHER SUGGESTIONS FOR IMPROVEMENT OF VISION AND AUDITION…
  42. 42 Lutein found in dark leafy veggies is important for vision. If you cannot eat these veggies for certain reasons (not the yuk factor either!), take 1000mg twice daily in supplemental form. Glutathione is in garlic, onions, asparagus, avocados, fish, eggs and can be taken as a supplement of 500mg daily A multivitamin with vitamin C (500mg), E (400 IU), Zinc 30mg) and Beta carotene (15mg) with a complex of B vitamins daily has been found to help vision and reduce chances of macular degeneration.
  43. 43 Smoking must cease due to its damaging effects on the blood circulation and reduction of oxygen to the eye and ear structures. Always wear protective sunglasses or goggles when performing sports or working outdoors. Indoor machinery and tools will also mean donning proper ear and eye protection. If you are working with solvents or powerful chemicals including bleaches, it is best to wear goggles. The eyes can be injured by splatter and splash.
  44. 44 All injuries to the eye and ears should be immediately reported to a doctor or health provider to avoid or protect these organs from further problems. See your ophthalmologist/optician yearly and have your hearing checked every few years. You may need more intervention than you realize. If you need surgery, make sure to check on the credentials and the successes of the specialists involved. Second opinions are always good, especially if you are unsure and feel uncomfortable with one doctor’s opinion or recommendation. On hearing, do not avoid a hearing aid if you have poor audition. It is very important to not lose your connection by the sense of hearing of you have always had it. Check on all resources to assist with payments for hearing aids.
