Diagnosis steps of hyperopia_Industry information_
If farsightedness is serious, blurred vision will appear near and far, and in order to make the image fall on the retina, the adjustment of the eye is always in a state of tension, which is prone to visual fatigue. The most common symptoms of farsightedness, let's take a look at the diagnosis of farsightedness. 1. The appearance of the eye is examined under diffused light, which involves the size and symmetry of the eyeball. Some people may have esotropia or esotropia, a type of strabismus that is mostly seen in preschoolers. However, there are also a small number of people with exotropia, which can be determined to be recessive or dominant by using the occlusion method. 2. Visual inspection, which is a common inspection method for many people with abnormal vision. Many young people have a strong ability to adjust. If they have mild hyperopia, their distance and near vision are relatively normal. If they have a high degree of hyperopia, their distance and near vision will decline. 3. Ophthalmoscopy The more common symptoms of hyperopia are a small, ruddy optic disc with blurred edges. People with high hyperopia may have pale yellow globules of transparent drusen, large ones may have visual field defects, and a crescent-shaped change will be formed under the nipple. Generally, such manifestations are considered congenital and do not cause significant reduction in vision. But the macula of hyperopia is farther from the nipple than in emmetrope. 4. Subjective refraction examination and objective retinoscopy examination, and combined with sphero-cylindrical lens to be corrected. If conditions permit, gonioscopy can also be done, and the anterior chamber angle is often slightly shallow. 5. In the case of infants and young children, when performing vision screening, the ophthalmologist needs to know whether there is a family history of esotropia and amblyopia in infants and young children. If so, the probability of high hyperopia will be relatively high. When examining infants and young children, pay attention to the head position and eye position. If it is abnormal, it means that there is refractive error. Hyperopia can be diagnosed by dilated optometry and fundus examination.
