Dynamic observation of primary and secondary analysis of low vision

Research 9, moderate 0.4 ~ O. 6, severe ≤ 0.3,[link widoczny dla zalogowanych], according to the following formula to calculate the incidence rate of new recovery rate. Incidence rate = new name of Yan Ang Cui recovery rate × 100 × 1002 = loop hand drum used by peddlers Gan Results and discussion 2.1 rate of low vision students with higher grades and higher learning (Table 1). According to 1989 data analysis, the rate of low vision since the second grade of 9.92 (28/252) straight up to a year high 67.79 (421/621). After 78t. / 3 years follow observation,[link widoczny dla zalogowanych], the beginning of 1987, the second grade,[link widoczny dla zalogowanych], regardless of what grade (the same people) are with the rate of low vision students in higher grades and increased learning. Such as the l987 year in fourth grade and first grade junior high school in first grade to l989 when the rate of low vision were 8.66 (47/543), 26.11 (158/605), 42.03 (261/621 ) increased to 28.10 (1,541,543), 45.62 (276/605) and 67.79 (421/621). This school year with the more severe the higher the learning task, with the burden of gradually raising the eyes, coupled with close operations tend to have less light (less than standard room lighting) is more affordable reusable eye, resulting in lack of ciliary muscle tension, leading to poor vision . 2.2 The growth rate of low vision increased with the year of change (Table 1), since students from hyperopia to myopia eye development process of poor vision than the growth rate has a negative value, followed by the increase [donate Han Jing, of School Health 1992l13 (I) a 3 '], 4,5 fastest growing primary grades. This is due to growth and development of young children in the twenty-spurt period (10 ~ l2 years old) coming of variation in physical development, plasticity, and there is a tendency to excessive myopia. This suggests the occurrence of myopia is a critical period, to carry out the work of myopia prevention should focus on the primary school stage. Combined method of treatment, the symptoms that most patients were hospitalized a week relief. Use of crude cottonseed oil to discourage people continue to eat,[link widoczny dla zalogowanych], ordering crude cottonseed oil manufacturers to stop production and sales. Etiology of this disease to the general public to the hazards and prevention measures such as Tibet. So the disease quickly under control. (19 have a l2-0l Received string together was the king of wood) * 29 * Volume 2 Practical Korea declined an anti-medical students three years of poor vision in the matter () Note the progress of growth, A is the rate of low vision, B for the fixed base ratio. 2.3 follow the same group observed the third form of low vision dividing the higher grades compared with the study, moderate to severe increase in the proportion. Reduce the proportion of mild (Table 2). Reflects the close operations due to poor vision from mild to severe from quantitative to qualitative change in the process, but also by the functional changes to the organic process of change. Table 2,[link widoczny dla zalogowanych], the same degree of low vision population composition observed Whole Story () changes in the incidence of 2.4 new with low vision increased with higher educational levels, the study a significant difference between paragraphs (Xl. = 136.35, P <0.O1 # by. = 81.40, P <0.O1), recovery rate is opposite. (X1 at a 33.89, P <0.O1} to. = 6.88, P <0.O1l Table 3). Primary school, the students also are functional low vision changes, when the ciliary muscle in patients with low vision students declined 3 new cases of low vision thing, restore the observation of spasm spread fast track, lens thickening, folding force is increased, the appropriate rest or treatment, the ciliary muscle relaxation, increased local blood flow, vision can be restored to normal, with the increase of learning tasks, with the eyes even more, a strong pressure drop in the regulation of the anterior chamber, vitreous cavity pressure increase, followed by eye shaft extension, the formation of organic changes can not be restored as soon as a result, primary school, students can be re-soap the lower edge of a large, pay close attention to this stage of the investigation rule, better effect.
