Medical Forum / General / Vision / August 200543 percent of natural eyes have diplopia -- Fincham
Dear John, Subject: 43 percent of normal eyes have diplopia. 1. Monocular Diplopia Caused by Ocular Aberrations and Hyperopic Defocus. Russell L. Woods, Arthur Bradly, David A. Atchison. Revised March 1996 Peragmon "... The second type of monoculary diplopia, however, seems to be much more common, and perhaps present in most eyes. Studies of otherwise normal eyes indicate incidences of monoculary diplopia of between 43 percent (Fincham, 1963)..." It is interesting. You could send me the full text of clause? Dear Alex, The text is fuzzy, so I can't copy it. I will type up some of it and post it here when I get some time. The implication is that eye with VERY SHARP vision have some "ghosting" or diplopia. I will state the author's location at the time of publication, and a correspondence author. With most of these scientific publications the author is pleased to discuss his paper with you. Best, Otis > With most of these scientific > publications the author > is pleased to discuss his paper > with you. Most of these scientific publications appear in a specific book or journal, published on a specific date. That way we can cite the article so others can find it and read the entire text. -MT Dear Alex, Here is the second paper by R. Woods on ghosting in the natural eye. 2. Consequences of Monocular Diplopia for Contrast Sensitivity Function. Pergamon Authors: Russell L. Woods, To whom all correspondence must be addressed: Department of Vision Sciences Glasgow Caledonian University Cowcaddens Road Glasgow G4 OBA, Scotland Arthur Bradly, School of Optometry Indiana University Bloomington, IN 47405 David A. Atchison. Centre for Eye Research, Scool of Optometry Queensland University of Technology Queensland, Australia ________________________________ Reference papers: Fincham, E. F., (1963) Monocular Diplopia. British Journal of Ophthalmology, 47, 705-712 Coffeen, P. and Guyton, D. L. (1988) Monocular diplopia accompanying ordinary refractive errors. American Journal of Ophthalmology, 105, 451-459 Dear Myopia prevention friends. I have received the following on "ghosting" for your interest. Since this is a private email, I will change the name of the sender. +++++++++++++++++++++++ Dear Mr. Brown: I have been following with great interest your latest postings on "Ghosting" or Diplopia. My main reason to contact you at this point is my concern that John may be commiting an error for something he can overcome by continuing with his vision therapy. As it happens, in the process of restoring my vision, and struggling with a stubborn astigmatism, I have noticed "Ghosting" in both eyes. In my worst eye (Right) the ghosting has actually changed. Originally the ghost image was at 11 o'clock position. As my vision improved, the ghost is now at 3 o'clock position, and disappearing. The left eye also has some ghosting that still shows up occasionally. I know it is related to the astigmatism in my eyes, because the astigmatic mirror tells me so. I have my own ideas as to why this is occurring, but the point is that I am getting rid of the ghosting. While there has been some discussion about John's complaint and his ghosting or diplopia, I am not aware he has had a thorough diagnosis. Unless I have missed those posts. Maybe the information at the following link: http://www.optometry.co.uk/files/2c8b0cc4c7b2636385085b3991c9f03e_finlay20001006.pdf maybe helpful, if John is not aware of the whole diplopia issue. Regards. Jo > Dear Myopia prevention friends. > [quoted text clipped - 38 lines] > > Kindly ask the sender post here. I have no diagnosis of diplopia, but you admit that plus lenses introduce diplopia, which is a defect, to one's vision, this is not acceptable. What am I supposed to see in tis study paper? > Dear Myopia prevention friends. > > I have received the following on "ghosting" for your >interest. Since this is a private email, I will change the name >of the sender. Otis, I have received your email. Kindly ask this "Jo" person to email me if he needs to point out certain facts about my ghosting in the right eye. Better yet he should come and visit SMV. Unless it is public discussion where ODs can see and verify, I have no interest in these dialogues. >Dear Alex, > >Here is the second paper by R. Woods on ghosting in the natural eye. Is ghosting less prevalent in the artificial eye? >Dear John, > [quoted text clipped - 10 lines] > > What about the remaining 57 percent? Yes I used to be in that 57%. Again, you better hope I don't have diplopia, or maybe start a research how I can get rid of diplopia.
