Download or read book Myopia written by Roger W. Beuerman and published by World Scientific. This book was released on 2010 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Myopia is the most common optical disorder in the world, and is on the rise in all parts of the world. The impact of myopia is evident as the driving force in the development of refractive surgery and of the eye glass and contact lens industries. Clearly, it is a lifestyle issue as well as a childhood disease that involves an unresolved problem in genetics. In Singapore (where myopia has reached the highest rates in the world) as well as in Taiwan and Japan, the affected group has developed greater degrees of myopia, leading to additional secondary effects on vision including blindness. This book provides a comprehensive coverage of all aspects of myopia. It is aimed at ophthalmologists, optometrists, opticians, scientists and pharmaceutical companies. The topics are uniquely treated in that they cover research at the laboratory bench as well as clinical applications. By maintaining a high level of research activity, future generations may be able to forego optical aids altogether.

This book was released on 2003-01-31 with total page 686 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past several decades, a significant international research effort has been directed towards understanding the composition and regulation of the preocular tear film. This effort has been motivated by the recognition that the tear film plays a critical role in maintaining corneal and conjunctival integrity, protecting against microbial challenge and preserving visual acuity. In addition, research has been stimulated by the knowledge that alteration or deficiency of the tear film, which occurs in numerous individuals throughout the world, may lead to desiccation of the ocular surface, ulceration and perforation of the cornea, an increased incidence of infectious disease, and potentionally pronounced visual disability and blindness.

Download or read book Toric Orthokeratology for Slowing Eye Elongation TO SEE in Myopic and Astigmatic Children written by Chia Chi Connie Chen and published by . This book was released on 2014 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results from the right eye or the eye with higher astigmatism were reported. RESULTS: A total of 35 ortho-k and 23 control subjects successfully completed the study. The mean ?SD myopia was -2.53 ?1.31 D at baseline. Myopia was significantly reduced to -1.33 ?0.80 D (42% reduction) at the 1-overnight visit and to -0.41 ?0.43 D (81% reduction) at the 1-month visit. The mean ?SD refractive (with-the-rule) astigmatism reduced from -1.86 ?0.64 D at baseline to -0.88 ?0.59 D (54% reduction) and -0.40 ?0.39 D (79% reduction) at the 1-overnight and 1-month visits, respectively. Corneal toricity reduced from -2.28 ?0.53 D at baseline to -2.01 ?0.61 (13%) at the 1-overnight visit and -1.28 ?0.52 D (44%) at the 1-month visit. Subjects in both ortho-k and control groups demonstrated axial elongation. At the end of study, the average axial elongation was 0.31 ?0.27 mm in the ortho-k group and 0.64 ?0.31 mm in the control group. Axial elongation was significantly slower in the ortho-k group than in the control group at every 6-month visit. The levels of reduction of myopia progression compared to the spectacle-wearing control group were 61%, 58%, 53%, and 52% (cumulative elongations) after 6, 12, 18 and 24 months of ortho-k lens wear. Axial elongation was significantly correlated with the initial age of the subjects and treatment assigned. ANCOVA analysis was conducted to test the effect of ortho-k treatment on axial length increase adjusted for age and the small difference in age did not bias the effect of the treatment. Moreover, axial length elongation was not affected by gender, initial myopia, initial refractive cylinder or initial corneal toricity. Significant changes in the anterior Sim Kflat and Sim Ksteep were observed in the ortho-k group, but only at the 1-month visit. No significant changes were observed in the subsequent visits with ortho-k lens wear. In the control group, no significant changes in anterior Sim Kflat and Sim Ksteep were observed during the study period. There were no significant changes in the posterior Sim Kflat and Sim Ksteep at all visits in both ortho-k and control groups. In the ortho-k group, significant CCT thinning of 7 ?9 om was observed at the 1-month visit (p = 0.004). No significant differences in CCT were observed in the subsequent visits. No significant differences in CCT were observed at any visit during the 2-year study period in the control group. No significant changes were observed in CH at any visit for both groups of subjects. In the ortho-k group, CRF significantly reduced from an average of 10.7 ?1.4 mmHg at baseline to 10.0 ?1.4 mmHg after 1-month of lens wear (p = 0.003). Again, no significant differences were found in the subsequent visits with continued ortho-k lens wear. In the control group, no significant change in CRF was found during the study. CONCLUSIONS: The toric design ortho-k lenses used were effective for myopic reduction and astigmatic reduction. The results also demonstrated the strong potential for the toric ortho-k lenses to control myopic progression by about 50%. Myopia reduction from ortho-k treatment involved flattening of the anterior corneal curvatures with no involvement of the posterior curvatures. Corneal biomechanical properties, in terms of CH and CRF, were not useful parameters to predict the ortho-k response.

Available in PDF, EPUB and Kindle. Book excerpt: Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued. The current list of Specialist Periodical Reports can be seen on the inside flap of this volume.

Book excerpt: Increasing number of myopic patients worldwide is a great concern and there are several methods of myopia control including orthokeratology lens. Orthokeratology is a fast growing, safest method of myopia control using a rigid gas permeable lens that halts myopic development. Although it is very common to encounter myopic patients in optometric office, it is difficult to find practice that offer orthokeratology to control myopia development. One of the greatest reasons that only few optometrists offer orthokeratology is due to the misunderstanding and impression of being 'hard' to fit orthokeratology lens on the patient with low success rate. This literature review collected studies to discusses basic knowledge of orthokeratology including its history and past and present anatomy of the orthokeratology. A very simple guide to fit orthokeratology will also be discussed together with clinical pearls that might be easily underestimated to many optometrists while fitting orthokeratology lens. This review also compared many recent studies from 2012 until today to discuss about side effects. Although it is very rare, it is important to be aware of side effects to prevent them. The most common side effect includes from corneal edema to most severe acanthamoeba related infection. This literature review also discusses many different recent studies regarding success rate among different groups of patients and patient feedback wearing orthokeratology, it all boils down to good basic knowledge of the orthokeratology lens and its fitting procedure by the prescriber. Furthermore, it is also as important to have a motivated and mature patient who diligently follows of the prescriber for the succesful fit of orthokeratology and myopia control.

Download or read book Orthokeratology written by Roberto Román and published by . This book was released on 2007 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Orthokeratology is the reduction, modification or elimination of a refractive error by the programmed application of special contact lenses. Orthokeratology is for people of any age who are myopes (nearsighted). The FDA has approved orthokeratology for people with up to six (6) diopters of myopia. Astigmatism can also be treated up to 1.75 "with the rule". Many doctors believe the best candidates are people who have low amounts of myopia, about four (4) diopters or less. The procedure can be performed on practically anyone of any age, as long as their eyes are healthy and the myopia does not exceed 6.00 diopters, and the astigmatism is within 0.25 to 1.75 with the rule, or 1.75 against the rule. Orthokeratology holds particular appeal for people who participate in sports, or who work in dusty dirty environments that can cause problems for regular contact lenses. Because orthokeratology offers similar benefits to LASIK, it's also appealing to adolescents and teens who are not elegible for LASIK. However, there are some concerns about corneal infections in young people who have used orthokeratology, mostly due to poor hygiene habit. Orthokeratology also has been claimed to be effective in slowing the progression of myopia (myopic control) in children. Orthokeratology can be both, a corrective and preventive control effect in childhood myopia.
