Workshop 6 â€“ Optometric treatment of amblyopia Dr.ÂŞ Susan Cotter
Southern California College of Optometry, USA
Amblyopia is the most common cause of visual impairment in children, and young and middle-aged adults. Most cases are unilateral and associated with strabismus, anisometropia, or both. Historically, occlusion therapy with aggressive patching of the sound eye has been the mainstay of treatment. Until recently, most existing data regarding the treatment of amblyopia have been retrospective and uncontrolled, with treatment regimens based on observations and clinical impressions rather than evidence-based medicine. To determine the optimal treatment for the most common forms of amblyopia, prospective randomized clinical trials and observational studies have been conducted recently in the United States and in the United Kingdom. The results of these studies have increased our knowledge and shed new light on our current understanding of amblyopia treatment. The goal of this workshop is to use an evidence-based approach to provide the optometrist with a current perspective on the treatment of childhood amblyopia. A case-base format will be used to address the following clinical questions: Is patching or are atropine eye drops more effective for the treatment of children with moderate amblyopia? What is the optimum dosage of patching for children with moderate amblyopia? How about those with severe amblyopia? What is the optimum atropine dosage to use for children with moderate amblyopia? What is the maximum improvement one can expect with atropine treatment? How long is treatment with atropine expected to take? Does a plano lens over a hyperopic sound eye augment the treatment effect? Can atropine be used successfully in patients with severe amblyopia? What is the significance of a refractive correction for amblyopic patients who are being treated for amblyopia? Does correction of the refractive error result in a treatment effect for children with anisometropic amblyopia and strabismic amblyopia? Are 3- and 4-year-old children more likely to benefit from amblyopia treatment than 5- and 6-year old children? Do near activities performed when the child is patched for amblyopia treatment augment the treatment effect? Is there an age after which amblyopia treatment is no longer effective? Is there sustained benefit in treating amblyopia in older children? Can bilateral refractive amblyopia be treated successfully with an optical correction? How long does it take for visual acuity to improve?
