Patient Q&A Section

Has treatment proven to be more effective than a placebo?

"Data from a recent study did not support the evidence that treatment is no better than baseline control in reducing myopia progression and its effects on visual function." - Anonymous Online Contributor

Have there been other clinical trials involving treatment?

"The majority of clinical trials were conducted in China, with less than 10% in other countries. Power makes it easy to evaluate the previous clinical trials for evidence to determine the efficacy." - Anonymous Online Contributor

Can myopia be cured?

"Myopic refractive error is not a permanent condition. It can be reduced to near-normal values, with the use of efficient lenses of the appropriate power." - Anonymous Online Contributor

How many people get myopia a year in the United States?

"Approximately 18.2 million US children are diagnosed with myopia in a given year. Since it is known that myopia is one of the leading causes of vision loss, these figures should be used cautiously given the recent decrease of myopia prevalence (a decline of the population factor) combined with the increased prevalence of nearsightedness (an increase of the population factor) seen in the population tested." - Anonymous Online Contributor

What is myopia?

"Myopia is the condition of nearsightedness. In the United States, around the year 2000, there was a steady increase in myopia among children, which may be caused by the increase in soft contact lenses. There is an increase in myopia globally; however, myopia is more prevalent in the developing world than in the developed world. In developed countries, the prevalence of myopia decreases with decreasing age. The prevalence in children is around 45%, and the prevalence in adults is 1.7%. Myopia occurs in approximately 30-50% of human beings and it typically worsens with age. It is highly prevalent in developed countries with high rates of vision impairment." - Anonymous Online Contributor

What causes myopia?

"There is no convincing evidence that any of the known environmental causes or genes are responsible for most cases of childhood-onset myopia. It is important to test for the effects of the GxE interactions found in other complex diseases for the prevention of myopia. Additional research is needed to determine if environmental factors other than those that can affect the eye's growth may play a role in causing hyperopia and myopia and their effects." - Anonymous Online Contributor

What are the signs of myopia?

"Symptoms of myopia include a change in nearpoint, change in accommodation and change in the depth of convergence. Patients with severe myopia may have problems seeing the print. Myopia can affect daily activities and may reduce the chances of having children. The signs and symptoms of hyperopia also have a negative impact on leisure activities. Severe myopia can result in poor driving skills, difficulty reading maps and poor distance vision. Hyperopia may not show any symptoms. Treatment involves using spectacles and appropriate correction is essential." - Anonymous Online Contributor

What are common treatments for myopia?

"In the developed world, myopia is treated by spectacles or contact lenses, while in the developing world most myopic people can only use myopic aids such as glasses or inexpensive contact lenses. In children, surgery such as corneal implant technology may be explored. The use of myopic aids by low-income children or by children who live in areas with more urgent myopia problems is a matter of further study." - Anonymous Online Contributor

How does treatment work?

"For treatment of myopia, the [LightPrescriptions_for_Patient_Controls(LightPrescriptions)] website provides a list of best-practice clinical procedures and products for the treatment of myopia. Most of these products aim to focus on correcting nearsightedness and can be helpful to treat myopia. This information can help [patients, caregivers, and professionals] decide which vision therapy is best for them." - Anonymous Online Contributor

Unverified Answer

Is treatment safe for people?

"Results from a recent clinical trial finds that the rate of complications arising from eye surgery for myopia and low myopic strabismus reported by clinical practitioners is very low. It would appear the vast majority of myopes have access to safe treatment and that only a minority use ophthalmic appliances. It is recommended that this practice change when evidence relating to the long-term risk of surgery is available. In the interim, it may be advisable for myopic patients to use low refractive accuracy instruments." - Anonymous Online Contributor

Unverified Answer

What is treatment?

"With current technologies, the choice of appropriate treatment for the treatment of refractive error is highly determined by the type of refractive error. However, to find relevant research for an appropriate therapy for refractive error, we must first summarize the factors determining an appropriate treatment in each refractive error. The treatment strategy, including [spectacle wear] and [contact lenses], must be designed according to [spectacles and contact lenses for refractive error] and [a correct and comfortable fit of those spectacles and lenses]." - Anonymous Online Contributor

What is the latest research for myopia?

"Patients with refractive error of-5.00 diopters (D or worse) are at least twice as likely to have retinal vessel pathology and half as likely to be diagnosed with early AMD than refractive errors of less than -5.00 D." - Anonymous Online Contributor
