“…This form of therapy uses a particular colour filter for treatment of certain conditions. Typically the treatment involves the patient viewing a circle of white light through the filter 68 . The web site of the College of Syntonic Optometry (http://www.syntonicphototherapy.com/online/) states that syntonics is ‘the branch of ocular science dealing with the application of selected visible light frequencies through the eyes’.…”

Treatment for amblyopia commonly involves passive methods such as occlusion of the non-amblyopic eye. An evidence base for these methods is provided by animal models of visual deprivation and plasticity in early life and randomised controlled studies in humans with amblyopia. Other treatments of amblyopia, intended to be used instead of or in conjunction with passive methods, are known as 'active' because they require some activity on the part of the patient. Active methods are intended to enhance treatment of amblyopia in a number of ways, including increased compliance and attention during the treatment periods (due to activities that are interesting for the patient) and the use of stimuli designed to activate and to encourage connectivity between certain cortical cell types. Active methods of amblyopia treatment are widely available and are discussed to some extent in the literature, but in many cases the evidence base is unclear, and effectiveness has not been thoroughly tested. This review looks at the techniques and evidence base for a range of these methods and discusses the need for an evidence-based approach to the acceptance and use of active amblyopia treatments.

“…Such is the complexity of the body's function that it is pertinent to consider that these two mechanisms may not be the sole mechanism to explain the phenomena of colour perception e.g. the observation, as studied in optogenetics, that neurons may be stimulated by light illustrates that a non-retinal mechanism may also be viable [111].This phenomenon of changes to colour perception was first recognised and investigated by Spittler in the 1930's [108].

IntroductionOur sense perception enables us to eat the correct amounts of food and, under normal circumstances, we cease eating when we have eaten sufficient food, and we drink sufficient to sati sfy the body 's need for liquid. We breathe at the normal expected rate, our heart pumps at the expected rate and maintain the normal level of blood pressure, our body maintains the normal levels of acidity and temperature, we sleep for 7-8 hours per night, etc. This suggests that the body is being regulated by a biological control mechanism of enormous sophistication and complexity, which has an enormous processing capacity; however as we age, and particularly as we age beyond 50 years, the mechanism which maintains our function become increasingly less able to sustain the levels of oxygen, blood glucose, blood cell content and a myriad of other biological components which the brain requires to function [1]. The i nnate g enetic c apacity o f key o rgans d eclines a nd r esults in shortages of proteins, hormones, etc. This h as a k nock-on e ffect affecting one biological sequence after another.The cumulative effect of our lifetime of experiences, due to environmental and biological factors, influences the function and/ or stability of the autonomic nervous system and ultimately the function of our DNA and genes [2]. The level of genetic expression of the proteins (genotype) which we require to sustain our function declines and the rate at which these expressed proteins subsequently react (phenotype) also declines i.e. the ability of the body to cope with extreme events declines.There are two fundamentally significant biological issues at play: (i) the genetic ability to express proteins (ii) the body's physiological demand i.e. the phenotype or influence of the environment. In the case of diabetes, in particular type 2 diabetes, this is the regulation of Blood Glucose. The greater the level of hyperglycaemia the greater is the associated demand for insulin. The development of a medical condition occurs when the environmental demand exceeds the body's innate capacity [3] i.e. the prevailing supply and/or level of insulin is insufficient to metabolise the excess of blood glucose. By contrast, the lower the level of hypoglycaemia, which occurs in type 1 diabetes, the lower is the demand/need for insulin. If there is insufficient blood glucose the excess of highly reactive insulin will seek an alternative substrate and ultimately results in damage to the peripheral blood vessels e.g. in particular to the brain, eyes, legs and feet.The evidence suggests that this regulatory process is performed by the brain via the process of neuroregulation [4][5][6]. This is a best-fit process which takes into account the prevailing state of development or physiological damage to a part of the brain, degeneration or damage to an organ (or limb), and the prevailing inter-cellular environment i.e. the feedback of biochemical signals from the viscera. AbstractDespite the immense advances of medical research there remains a fundamental theo...

“…Sooner, in 1920's Dr. Spitler H. R. contemplated the principles of modern ocular phototherapy (Syntonic) [27], which represents the balancing of parasympathetic and sympathetic nervous system. This was followed by practicing all kinds of experiments with sun lamps to treat circulatory diseases [28] and many other degenerative disorders such as peritonitis [29].…”
