Diabetes and retina

 diabetes and your retina

The retina is only three cell-layers thick. This is extremely thin! The layer which rests against the choroid receives its blood supply and vital oxygen from the choroid blood capillaries. The outer layers, however, receive their blood supply directly from blood vessels serving this region of the retina directly. So in fact, there are two separate sources of blood for the retina, a fact which will become of critical note when we discuss various retinal complications.

The outer surface of the retina which is attached to the vitreous humour contains the photosensitive cells known as rods and cones, as mentioned in an earlier chapter. These two types of cells are capable of receiving the various light inputs which come from the outside world, and of translating this light energy into an electro-chemical signal which is sent to the brain for processing and for the final experience of seeing.

We have now come to the most common cause of blindness in our culture today. We have also come to a discussion of the most rapidly spreading disease in our culture: diabetes.  Specifically, diabetes mellitus.

There are 10-20 million diagnosed and undiagnosed diabetics in the United States alone, and this figure is doubling every fifteen years. Traditional theories as to this radical increase in the disease are linked to genetic factors. Because diabetic people are being kept alive so they can reproduce, so the theory goes, more and more diabetic genes are being transferred into the population, with the resultant increase in the disease.

This is certainly part of the picture. But we should at least briefly discuss the alternative point of view as to the cause of diabetes. This has to do with the stress factor in diabetes. In the same way that families pass on genes which can cause a weakness in the organs affected by diabetes, they can also pass on an emotional profile of chronic stress and over-arousal syndromes, which also seem to generate a failure in the organs associated with diabetes.

To what extent are diabetic genes proliferating in our culture, as opposed to the proliferation of stress and chronic arousal syndromes throughout the population’? This is a question which needs to be determined, to really deal with the increase of diabetes in our communities and at large.

retina miracles and tragedies

 retina miracles and tragedies

“We have now explored almost every major aspect of our eyes. We have seen how the shape of the eye and the curvature of the cornea can affect vision. We have taken a close look at the inner crystalline lens and the muscles which alter its focusing shape. We have considered the purpose and problems of the aqueous humour as it is created by the ciliary body and flows down through the front chamber of the eye. And we have seen how the extraocular muscles which surround and move the eyes make possible stereoscopic vision, and at times interfere with this vision. Except for the back sections of the eye, we have made a full survey of function, problems, and cures.

But we have still ahead of us a most remarkable aspect of vision, the actual processing of the light which enters the eye into electro- chemical information to be sent to the brain. And for this final phase of our journey, we find ourselves face to face with a seemingly miraculous region of the eye called the retina.

The retina is a thin, photosensitive layer of the eye, covering the inner surface of the back regions and held in place by the jelly-like substance which fills the back chamber of the eye. This jelly-like substance is called the vitreous humour, and we should first take a look at this rather large section of the eye, to see its relationship with the retina itself.

The vitreous humour, unlike the aqueous humour in the frontal chamber, is not in circulation. Instead of being regularly (every four hours) replaced by new liquid, it is a permanent jelly, serving the main purpose of holding the eye to its proper shape, and holding the retina in place in the back curved regions of the eye.

I have been studying this part of the eye for a number of years already, and will certainly continue to study it for the rest of my life without fully understanding it, because our scientific grasp of its functioning is still in its infancy. The deeper we look, the deeper the mystery becomes. But this is true with all of science as we look at the infinite depths of the universe, and so for now we must be content with our present level of understanding.”

the glaucomas -inner eye pressure

the glaucomas – inner eye pressure

The term glaucoma carries with it an aura both of mystery and anxiety. Glaucoma is a devious condition, in that no noticeable symptoms develop until after damage has actually begun to occur in the visual system. The only early detection method is a regular yearly check-up with the eye doctor, who can perform simple tests to determine if glaucoma is or is not developing.

As we have already seen briefly, the interior of the eye is filled primarily with liquid. There are two main chambers inside the eye, the frontal chamber which is filled with aqueous humour, and the back chamber which is filled with a more permanent jelly called vitreous humour.

Glaucoma is a condition which develops in the frontal, aqueous chamber, and which then affects the entire eye in that it increases the overall pressure inside the eye.

There are two alternative understandings of the cause and treatment of glaucoma. First we will consider the traditional medical model of this condition, and then we shall expand the discussion to explore a more holistic understanding, and present a new method of treatment. These two approaches are not mutually exclusive. Actually, the newer approach builds upon the firm base of medical science, and looks one step further into the causal factors of the condition. With both points of view in place, we should gain a stereoscopic perspective on the problem, and have a clear notion of how to proceed.

As with all other parts of the body, the eye must maintain an optimum balance between the outside world and the interior realms. With glaucoma, we find the development of a crucial imbalance. The interior pressure of the eye begins to increase, generating numerous complications for the functioning and health of the organ.

Traditionally, the aim of medical treatment of glaucoma has been to detect an increase in pressure of the eye as soon as possible, and to use drugs to control the pressure so that no more damage will be done to the optic nerve. If the condition is detected soon enough, lifetime drug therapy can control glaucoma and preserve the vision intact.

Presbyopia conditioning

presbyopia conditioning

As with hyperopia, presbyopia is an inability to focus clearly on objects which are near to your eyes. But presbyopia is different from hyperopia in its physical condition.

Whereas hyperopic eyes are distorted through an incorrect shape of the eyeball, the presbyopic eyes actually retain a normal eye shape. The difficulty with presbyopic vision is found in the functioning of the focusing apparatus, specifically the ciliary muscles and the interior lens of the eyes.

The interior lens (as differentiated from the refractive functioning of the cornea) is surrounded by the ciliary muscle. This is a circular muscle which expands its inner diameter when it relaxes, and reduces its diameter when it contracts.

The ciliary muscle is connected to the periphery of the lens by fibers called zonules, which are suspensory ligaments which support the lens in position. When the ciliary muscle is relaxed outward, it pulls on the zonules and thus pulls the lens into a flattened shape, which is necessary for focusing in the distance.

When the ciliary muscle receives orders from the brain to contract, the pressure on the zonules is relieved and the lens assumes its inherent curved shape due to its natural elasticity. The difficulty called presbyopia develops when the lens begins to lose its natural elasticity, and fails to assume an adequately curved shape when the ciliary muscles contract for up-close vision.

So our question in approaching presbyopia is this: what causes the lens to lose its natural elasticity, gradually reducing the ability of the eye to focus up-close?

In considering preventative programs for postponing presbyopia, circulation and diet should play a vital role in helping to maintain optimum health of the cells within the lens.

Another factor which is often forgotten in the consideration of presbyopia, is the health and vitality of the ciliary muscle surrounding and controlling the shape of the lens. Like all muscles in our bodies, this muscle can be in good shape or in poor shape. And like the rest of our body, the ciliary muscle can age relatively early in life, or remain strong and vital to a very old age.

…in the next posts we will consider this condition from the alternative point of view.

Hyperopia and breathing

hyperopia and breathing

Curiously, most babies are born with hyperopic eyes, and our first weeks and months of seeing are defined by this inability to focus clearly on near objects. The eyes are not fully developed at birth, and continue to grow and alter their shape for a number of months until sharp focusing is possible.

For this reason, an understanding of hyperopia is possible from the psychological-causation approach, as well as the genetic approach.

Research has not yet been completed to determine the accuracy of this new theory, but if you are hyperopic, or if your child has this condition, you can evaluate the logic for yourself: could early childhood traumas inhibit the development of visual functioning and shape? Is there a correlation between negative environmental conditions in infancy and a tendency towards hyperopia?

Hyperopic children tend to have breathing patterns which inhibit general expression as well. The breathing is usually shallow, high in the chest, and frequently held. This reflects an early childhood condition of apprehension and uncertainty.

Even if you do not think you can recover from your visual condition, you should consider whether you have this breath inhibition which limits your emotional and mental functioning, and take steps to recover from this habit.

Specifically, the exercises already described in Part One of our Natural Vision Holistic Program, which integrate visual movements with smooth rhythmic breathing, are ideal. As soon as you begin to focus on your breathing, you will notice ways in which the full exhalation is blocked, and recurrent times when you hold your breath rather than breathing smoothly through a breath cycle. Simple awareness of your breathing will generate positive alterations. And if you want further guidance in this direction, a complementary text called Responsive Breathing is available.

Cataracts what causes the lens to turn cloudy

what causes the lens to turn cloudy?

Complementary to our discussion of presbyopia is a consideration of the condition called cataracts, because both conditions are primarily focused on the lens inside the eye, and both are usually associated with ageing.

A cataract is any clouding of the crystalline lens so that the passage of light through the lens is interfered with. Although usually a problem of old age, people of all ages can develop cataracts, and even newborn babies sometimes have cataract clouding in the lens. Such diverse conditions as measles, diabetes, reaction to drugs, eye injuries, and alterations in body metabolism are associated with the development of cataracts.

As with so many other visual conditions, there is still no scientific explanation for the development of cataracts, and throughout the literature on the subject we encounter such statements as ‘no one really understands fully what causes the lens to turn cloudy.” In fact, the basic causation models in most illnesses are currently under question, as the impact of Einsteinian relativity and quantum mechanics data put into doubt the models of molecular biophysics.

All we can point to currently is the rising evidence that health and disease are factors of the individual in relationship to the environment. Our attitudes, diet, exercise, sense of time, and emotional health seem as important as our genetic and biological dimensions in remaining healthy; Cataract development certainly fits into this understanding also.

But regardless of the causes of cataracts, they are a primary source of visual failure. Over 400,000 cataract extractions are performed through eye surgery each year in the United States alone, and it is estimated that over 10 million individuals become visually disabled in the United States each year because of cataract. Fifteen per cent of the population between the ages of 52 and 85 have cataracts which noticeably reduce their visual potential.

how to get rid of myopia without surgery

how to get rid of myopia without surgery

Welcome to this cultural space created to rediscover and  remember the limitless potential of self healing that we all possess as spiritual beings in all moments of our visual and vital experience. 

With every hour that passed, more and more doctors and scientists agree that our emotional habits, mental states and behavior models influence in the health and vitality in a direct and powerful way. More and more new methods of self-help arise in those which these internal states, instead of being ignored, foment and potency the healing.

More than a simple repetition of the traditional point of views on the functioning of the eyes and development of the eyesight illnesses, we want to dedicate this space to something much more joyful.  Especially, we like stand out the deepest aspects in the vision; the correlation between emotions, mental states and the visual habits.

Also you will find here quite different focus on causes of vision problems as well as descriptions of some practical and natural techniques that allow to connect your conscious desire of a clear vision with the biochemical functioning.

The method I’m talking about is based on the research and work of the North American therapist and psychologist John Selby.  I have used these techniques to improve my own vision and recover from strong myopia and astigmatism without any external help.  These techniques are still in the experimental stage; nevertheless I consider them as excellent tools capable to guide you toward a notable progress in your visual health. And you can apply them without any risk.

Once becamoming free of myopia, now I like to share this very valuable knowledge with all visitors and subscribers to my blog.
