Visual disability includes low vision and blindness. Low vision means that the best corrected visual acuity of both eyes is still lower than 0.3 but better than 0.05 after the patient’s experience of optical prescription; if the visual acuity is lower than 0.05, or the visual field is obviously reduced and the radius of the field of view is less than 10°, then the patient is blind. The number of patients with visual disability in China is large, and the results of the 2006 National Sample Survey of Persons with Disabilities show that there are 12.33 million patients with visual disability in China, close to 1% of the total population. Eye diseases that cause visual disability are most common in developing countries with cataracts, and in developed countries with age-related macular degeneration (AMD) and diabetic retinopathy, and in children with congenital hereditary eye diseases. China has the highest number of myopic eyes in the world, and high myopia is prone to complications such as macular degeneration, hemorrhage and retinal detachment, and is one of the common eye diseases of visual disability. The World Health Organization (WHO) estimates that less than 2% of people with visual disabilities worldwide actually receive low vision rehabilitation treatment, and the rate is even lower in China. Medical units that carry out low vision rehabilitation treatment in China are mainly concentrated in a few large and medium-sized cities such as Shanghai, Beijing, Tianjin, Guangzhou and Wenzhou. Cataracts can be treated surgically to restore sight, but for those cataract patients who cannot undergo surgery due to physical or other reasons, or for other low vision patients whose vision cannot be further restored by existing medical treatments, low vision rehabilitation help will be the only possible way to improve the quality of life of these low vision patients. Low vision rehabilitation means to provide the visually disabled patients with appropriate visual aids and through appropriate training, to enable them to master the use of the visual aids, to be able to maximize the use of their residual useful vision and to improve their ability to live independently. With the help of low vision aids, they can carry on a normal life, participate in outdoor activities and recreation, and can even participate in work, and children with low vision can accept normal human learning. Commonly used low vision rehabilitation devices include non-optical vision aids, optical vision aids and electronic vision aids. Non-optical aids are the most familiar and include large print and other large devices, devices to assist with writing, and devices to control glare, contrast, and illumination. Optical aids include magnifiers, telescopes, and tricorders that expand the field of view. Electronic vision aids (CCTV), compared with optical vision aids, have the advantages of high magnification, large field of view, and the ability to adjust contrast and brightness, etc. They are especially suitable for patients with severe low vision and severely reduced field of view who are ineffective with optical vision aids, but CCTV is more expensive. We have been carrying out low vision rehabilitation treatment for many years, and in December 2007, we officially opened a low vision specialist clinic, which is held every Thursday afternoon. The main rehabilitation targets of the low vision clinic are patients with various causes of visual disability, including retinal detachment, cataract, glaucoma, ocular trauma and other eye diseases, whose vision cannot be further restored after treatment with ophthalmic drugs and surgery, and whose condition is relatively stable. Through low vision rehabilitation treatment, their ability to live independently is improved.
