Prent.txt Subject: Medical Recommendation for plus-prevention. Here is the publication of a medical doctor who: 1. Deduced that prevention would be possible (before the minus), and 2. Stated that the "public" (you and I) would most likely REJECT this method -- because of the judgment required to do this effectively. 3. Recognized the Snellen-clearing would be possible, but not much beyond the -1.5 dioter (20/60) stage. Enjoy, Otis ================================= By Chalmer Prentice, M.D. Transcription (c) A. Wik, 2004 ----------+ | Chapter IX | +-------- The following are some very interesting experiments in myopia which can be verified by any operator, and which prove that refractive myopia depends on ciliary spasm, and that, even in axial myopia, considerable repression can sometimes be made at the near point. In either class of cases, repression must be made at the near point. In various lengths of time, we shall be able to reduce the myopia one or two dioptres, sometimes more. In most cases satisfactory results will require considerable time and patience; but a few experiments after the following example will suffice to show that in some very advanced stages of myopia, it is possible to suppress, or at least check, its onward course by repression at the near point. This fact renders the fitting of minus glasses to myopic eyes an open question. EXAMPLE CASES Age forty-three; myopia; had been wearing over the right eye -1.25 D, left eye -1 D, with little or no cchange for the space of two years; eyes in use more or less at the near point. I recommended the removal of the concave glasses for distant vision and prescribed +3.50 D for reading, writing and other office work. After reading in these glasses for several days, the patient was able to read print twelve inches from the eyes. This patient was of more than ordinary intelligence and understood the aim of the effort. In six months I changed the glasses for reading and writing to a +4 D without seeing the patient. After using the +4 D glasses for several months he again came under my care for an examination, when the left eye gave twenty-twentieths of vision, while the right eye was very nearly the same, but the acuity was just perceptibly less. ++++++++++++++++++++++++++++++++++++++++++++++++++ Similar results have been attained in 34 like cases; ...but the process is very tedious for the patients, and unless their understanding is clear on the subject, it is almost impossible to induce them to undergo the trial. ++++++++++++++++++++++++++++++++++++++++++++++++++ [Comment: Anyone considering "prevention" must understand this issue. There is no "easy way" of prevention. As Chalmers said -- the person must fully understand this issue. It is for this reason that I suggest full transfer of "control" to the person himself. If he lacks the motivation to look at the chart, and "clear" himself, then no "third party" (i.e., OD) can do it for the person. This is why I separate a true-medical problem from preventing a negative refractive status in the natural eye. I believe that the above statement simply clarifies that point. OSB] ________________________ Subject: Realizing the truth Dear Scientific friends, Subject: Second-opinion on preventing negative refractive states. I suggest that there is a profound difference concerning "pure science" and "pure medicine". And I suggest the difference is this: Medicine: Must deal with a great mass of people walking in off the street. There might be some "intelligent" people but that can never be the assumption of the medical doctor. The result is that we get "canned" procedures that "work" instantly. I consider that people in this profession have no choice but to conduct that kind of work -- and I would do the same thing IN THEIR PROFESSION. That would not make it "right" but I do understand them -- and what they are doing. Science: Must "step back" from that situation, and think about the behavior of the natural eye as a dynamic system. Engineers and scientists simply do not deal with children, nor with others that do not understand the need to work on prevention with the plus. But when you ask very fundamental questions about whether a population of eyes (primates) are dynamic, you get the "second-opinion" answer, that POTENTIALLY a negative refractive STATE could be prevented -- before the minus lens is applied. I believe that pure science (i.e., the SCIENTIFIC -- not medical experiments -- proves this point.) But that is the nature of our arguments. Many concepts in science simply can never be reduced to "medicine" and we should understand that truth. This how we should separate "medical issues" from scientific concepts -- experimental and objective testing. But that is why it took a scientist like Dr. Stirling Colgate to do the "work" correctly and clear his vision from 20/70 to normal. His statements are confirmed by direct experiments with the primate eye, again on a pure-scientific (not medical) level. Please use the term "refractive state" where the natural eye can have positive and negative refractive status (as a dynamic device) and this analysis will become much clearer. Best, Otis
