Abstract: at the national study class on macular diseases recently held by Beijing hospital, experts pointed out that macular disease has become the first cause of blindness in the elderly. It is suggested that the public should check the fundus every year after the age of 50.
macular region is an important region of the retina, located in the posterior pole of the eye, which is mainly related to visual functions such as fine vision and color vision. Once there is a lesion in the macular area, there is often a decline in vision, black shadow or visual deformation. At the national study class on macular diseases recently held by Beijing hospital, experts pointed out that macular disease has become the first cause of blindness for the elderly. It is suggested that the public should check the fundus every year after the age of 50.
if the eye is compared to a camera, the macula is equivalent to a negative film. Dai Hong, director of Ophthalmology of Beijing hospital, said that in urban areas, senile macular disease has replaced cataract and become the first cause of blindness in the elderly. Most of the early symptoms of macular lesions are visual impairment on one side, changes in visual objects, deformation and distortion, and dark shadow or flash in the center of visual field. He suggested that patients can often do self-examination, such as looking at the “straight line” such as window lattice, door frame and clock pointer alternately with one eye, comparing the visual state of the two eyes. If abnormal “straight line bending” is found, they should seek medical examination in time; In addition, people over the age of 50 had better check the fundus every year.
Dai Hong said, “early intervention can effectively alleviate the progress of the disease.” At present, the treatment methods of macular diseases include photodynamic therapy, anti neovascularization therapy and so on. No matter what kind of treatment is adopted, “the earlier the treatment, the better the effect”.
warm reminder: senile macular degeneration, macular vitreous wart is in the earliest stage of the disease course, and the lesion is the lightest, but it has a great potential risk, so we should not be careless at this time. In patients with juvenile macular degeneration, the early central visual acuity decreases, but the fundus changes are not obvious. At this time, early medication should be found in time and treatment should be insisted. In the process of any disease, the earliest stage of the disease course and the lightest stage of the disease are the best treatment opportunities, and there are more opportunities to prevent the progress of the disease course.
