From contact lens practice and the search for a better means of diagnosing primary open angle glaucoma by studying the central artery and vein of the retina for nasal shift (believed to predate the permanent visual field defects that characterise this ultimately blinding disease) came what has been described by medical colleagues as a historic discovery. A an actual change in the structure of the vessels under observation for microscopic displacements within the optic nerve head (disc or papilla) was observed to be apparently associated with the consumption of vitamin C and possibly other antioxidants and nutrients. This has to be fully researched. The new field of optometric diagnosis was discovered in 1999 after the first of the electronic fundus (retinal) camera/microscopes was introduced into the practice in 1998. The procedure was named CardioRetinometry and the intervention protocol was named Nutritional Preventive CardioRetinometry. Informal study has resulted in the discovery that actual reversal of cardiovascular ageing has been recorded for up to ten years with no sign that the limit has been reached. Assuming (as an example) that the regression of atherosclerosis has reached its limit at this time (2008) it might be fairly hypothesised that the period during which the regression of arterial and in many cases venular plaque occurred, would be matched by a similar period during which reversal would take place. Conservatively, since rapid regression has been seen in some cases after abandonment of the lifestyle/dietary measures, it is considered reasonable to halve this period of time and assume that an additional five year period can fairly be predicted before complete reversal to the original vascular state might be observed. This would benefit subjects to the extent of an apparent 15 years extension to their (cardiovascular) life expectancy. Informally the research is proving very rewarding but clearly now that the reversal of retinal vascular pathology has been proved photographically by thousands of images of hundreds of contact lens wearing patients returning with great regularity for 6 monthly examinations, it is clearly a predictable, measurable, and semi-permanent feature of human life. This being so, the origins of disease are being observed. Hypertension is seen to ease with reduction of swelling of veins and recovery of normal curvilinear form of blood vessels which were becoming distorted before reduction of the internal plaque blocking blood flow. Tortuosity of the retinal arteries has been observed to result from lengthening of the vessels between fixed points under excess pressure leading to retinoschisis (splitting) and actual detachment. The Institute of CardioRetinometry was founded to organise research into this new field of optometric/medical investigation and to develop links with other centres interested in this area promising actual life extension.
