Patient Q & A Section
What are the signs of vision, low?
Symptoms of low vision include blurred central vision. These symptoms are common after age of 65, may be noticeable even in midlife, and can be treated. There may also be problems focusing on text and performing small or fine details like writing, cutting or sewing. Patients may wish to be able to read a newspaper or use a computer at home or at work. The patients may also prefer to read to self-assess and self-validate. Vision, low syndrome may be an undertreated disorder. It is recommended that more knowledge of symptoms be disseminated and more effective methods of identifying low vision be developed.
What causes vision, low?
Vision, low may be one of the key reasons that causes individuals to be anxious about their visual abilities. It may also explain why it is difficult to find the right preventive strategies among those without vision, since sight is a vital sense. We also suggest that more research, using qualitative methodology, is necessary to identify the cause(s) of vision, low.
Can vision, low be cured?
Given that the present study is the first to report the prevalence, characteristics and treatment outcome of patients with refractive low vision and that refractive low vision has been described before in patients with low vision with high myopia (myopic lazy eyes), it has been concluded that the vision, low type is one type of refractive lazy eye. However, patients with refractive low vision not having any visual complaints or vision correction (only myopic lazy eyes) will not be treated by refraction plus glasses. Therefore, in the clinic, only refractive, low vision is diagnosed not only by a refraction in a standard way which is an outpatient clinic but also by an eye chart.
What are common treatments for vision, low?
The majority of patients were prescribed a spectacle or eyeglasses for refractive errors. There are more than twenty-five types of lens solutions available, from single-use to carefully labeled solutions as to the correct preservative or preservative replacement, correct type, strength, and duration of the solution and the type of solution for each prescription. Contact lenses are commonly prescribed to treat mild to moderate dry eyes or corneal opacities. Contact lenses can be cleaned with the solution included in the solution, worn in conjunction with eye drops, or used as a contact lens solution.
How many people get vision, low a year in the United States?
Vision (both total and ophthalmic) and eye health metrics have improved in the U.S. over the last decade. Sight-lost is much lower now than it was in the early 1990s. The reasons for this improvement may not be entirely due to vision screenings, but are more likely due to changes in diagnostic techniques, the increased availability and accuracy of eye care services, and better eye care education and accessibility in the U.S.. In particular, children are much more likely to have access to an ophthalmologist as compared to 10 years ago.
What is vision, low?
The first line of care for patients with vision, low, involves an appropriately trained family doctor in the context of their health care team. Physicians should be able to provide high quality, patient-centred, primary care with access to specialist care when appropriate.
How serious can vision, low be?
The vision, low was determined solely based on self-image and a brief history of vision loss. If vision is impaired in a person without an additional major systemic (i.e. systemic connective tissue) disorder, vision, low is not a vision issue.
Is low vision rehabilitation typically used in combination with any other treatments?
There may be indications for using low vision rehabilitation in combination with visual rehabilitation after bilateral cataract surgery. This may be beneficial in cases of a weak pretreatment vision of 20/200 or worse and a strong deficit in central visual acuity after surgery. If a patient has already had a cataract extraction surgery, visual rehabilitation is not mandatory, unless they have a vision of 20/200 or worse. In the case of preoperative vision 20/200 or lower a new surgery should be discussed. Patients with a good visual acuity of 20/400 or better should routinely receive this rehabilitatory program after cataract surgery.
Have there been any new discoveries for treating vision, low?
While [new treatments are being developed to treat eye diseases on a regular basis, most recent discoveries have come from [diseases of the retina] on their outer layers of the retina, such as cataracts. If the disease is localized to one area of the retina, then you can get vision if you can get the disease localized. (https://www.eMedicine.com/articles.
What are the common side effects of low vision rehabilitation?
Low vision rehabilitation may produce a range of side effects. These side effects may be predictable, and may be ameliorated by appropriate intervention. In particular, attention to correct visual presentation and correct and appropriate light level lighting before and during training may help reduce the severity of such symptoms.
Has low vision rehabilitation proven to be more effective than a placebo?
This randomized, controlled, open multicenter study demonstrated that patients who received low vision rehabilitation services were significantly more satisfied with vision-related performance than those who received a placebo service.
Is low vision rehabilitation safe for people?
People with low vision reported increased levels of well-being and satisfaction when they received support from an optometrist. When combined with appropriate rehabilitation, such support appears to be safe and acceptable to patients, family, and carers.
