This course covers (i) basic concepts of evidence-based medical practice with special reference to eye and/or vision care, (ii) fundamental biostatistics and epidemiological study designs with the focus on the concepts essential to understand the quality of evidence, (iii) strength of evidence on disease diagnosis, prognosis, therapy, and risk, (iv) resources to identify current best evidence.
Basic pharmacology, terminology, and concepts (both pharmacodynamic and pharmacokinetic) and pharmacotheraphy of medical conditions commonly encountered in clinical optometric practice (including cardiovascular disease, respiratory disease, diabetes, infection and inflammatory conditions, as well as central nervous system disorders).
Problem-based learning approach using clinical case examples (continuation of 206A-206B).
Direct patient care and supervising OD residents in optometric care of children and young adults with progressive or high myopia. In addition to providing conventional glasses for clear vision, more importantly our services include options for controlling the progression of myopia. These options are likely to benefit most those with early onset, i.e., whose nearsightedness developed before the age of 10 years, and/or fast-progressing myopes who are at greatest risk of becoming high myopes. A positive family history of high myopia represents another risk factor.
Optical Control of Myopia Progression
The emphasis of my research has been on the investigation of optical influences on emmetropization and the development of myopia. Using chicken as a model, I have identified a number of optical designs that significantly inhibit myopia progression, thus have potential translational value in controlling human myopia. Additionally, I have been designing and fitting contact lenses to young guinea pig cornea to evaluate the safety, feasibility and effectiveness of contact lenses as a method of inducing defocus for myopia research in mammalian models.
