Macular degeneration with glaucoma, diabetic retinopathy and caused a par of blindness in old age, one of the three major culprits. Macula is a normal structure of the eye, the retina in the eye, because anatomical specimens so called yellow macula. This is the vision of the most sensitive areas of human vision is extremely important role. Age-related macular degeneration is age-related chronic eye disease, affecting reading, driving, identifying the time and facial features, etc. Although the age-related macular degeneration rarely cause complete blindness, but the central visual impairment, the patient's daily life will be very a big impact. China's people over the age of 50 age-related macular prevalence rate of 15.5%, the majority of patients failing to timely treatment, thereby adversely affecting the condition, leading to a serious disease, even blindness. Age-related macular degeneration is divided into dry and wet, dry common symptoms of mild blurred vision, moisture will lead to sharp decline in visual acuity, the patient may be blind within 2-3 months. And cataract surgery to restore the blinding disease can be compared to the consequences of age-related macular degeneration is more serious and can cause irreversible vision loss. Cause of age-related macular degeneration is not clear. However, a large number of studies have shown that age-related macular degeneration with age, heredity, environment, smoking and other factors. More women than men, illness, immediate family members of patients with age-related macular degeneration and smoking a high incidence of people aged 50 or older, history of diabetes, history of hypertension, hypercholesterolemia groups are age-related macular degeneration in high-risk population. Early detection, early treatment to prevent the disease progress, the maximum to maintain the existing vision-related macular degeneration is the main goal of treatment is the key to the treatment. Patients can self-test to detect disease, help physicians to gain time in order to maintain maximum vision. When you feel blurred or disrupted, the central vision with bending and deformation, such as looking antenna, the surrounding buildings when wave-shaped, or the central image appear black or white shadow must be vigilant. To know if suffering from the disease, a kind of very convenient way at home self-testing: A black thick white line painted by 10 cm × 10 cm square sheet, the central point. The grid sheet on the flat line of 30 cm depending on the distance, light should be sufficient, on average. If Life is wearing glasses, is required to wear glasses to inspect the original. For the elderly should also be wearing reading glasses to be checked. Hand covered his left eye, right eye gaze center of grid table. When the gaze center white spots, we found the table center or other white grid lines appear bent, broken or deformed, or some of the space grid appear blurred or vacant, it may be retinal macular defects, as soon as possible to find an ophthalmologist in detail detection. In recent years, prevention and treatment of age-related macular degeneration, there are more basic and clinical research results, such as photodynamic therapy can stabilize and control the development of age-related macular degeneration and improve the patient's visual function. Even with advanced age-related macular degeneration, depending on the function of the serious and irreversible damage occurred may also help, as the technology to increase through the patient's quality of life. 2009-10-21
