高度近视是较常见的眼屈光不正疾病,在我国有较高的发病率和致盲率。
High myopia is a common eye ametropia disease with high incidence rate and blinding rate, especially in our country.
为应对慢性眼疾日益沉重的负担,世卫组织目前正在制定针对糖尿病性视网膜病变、青光眼、年龄相关性黄斑变性和屈光不正的政策和准则。
In response to the increasing burden of chronic eye disease WHO is now developing policies and guidelines for diabetic retinopathy, glaucoma, age-related macular degeneration and refractive errors.
模型有较强的通用性,适用于传统仅矫正屈光不正(近视、远视、散光)的光学区模型,也适用于波前像差引导的激光眼屈光手术。
The model not only can be applied to the correction of refractive errors such as myopia and astigmatism, but also can be used in wavefront guided laser refractive surgery.
方法随机选取正视眼及各种类型屈光不正的人群583例1 111眼,先行常规视力及屈光检查,然后分别对其进行针孔镜测试。
Methods In 583 cases(1 111 eyes) randomly collected, the routine check of the vision and refraction were done, followed by examination by the pinhole.
目的:借助波阵面像差仪研究正视眼及屈光不正眼的高阶像差。
Objective: To study the higher order aberrations of emmetropic and ametropic eyes with wavefront aberrometer.
结论:模拟训练法可提高患者的认知能力,降低屈光不正矫正手术中头位和眼位的偏移率。
Conclusion: Simulated behavior practice can improve patients cognitive abilities and can decrease the possibility of position change of eye and head during the operation.
结论准分子激光手术有效提高屈光不正眼的裸眼视力。
Conclusion Excimer laser cornea reshaping can improve the visual acuity of ametropia.
亚洲人群屈光不正和青光眼的流行病学特征已经比较明确,但对糖尿病视网膜病变和年龄相关性黄斑变性等重要致盲原因的研究尚有欠缺。
While the epidemiology of refractive errors and glaucoma have been well characterized, there are few population-based knowledge on diabetic retinopathy and age related macular degeneration.
方法:在实验室搭建实验装置,分别利用矩形光栅法的实验装置和平板法视网膜MTF测量仪器,来测定正视眼组和屈光不正组的不同空间频率条纹分辨的阈值,算出并分析比较所测MTF值。
METHODS: Retina MTF of two groups of people with emmetropia and ametropia were measured by means of a grating and parallel plate respectively. Then the measured MTF were compared and analyzed.
结果:表现为视力下降59例,其中糖尿病性视网膜病变44例,由于血糖变化导致屈光不正15例,眼外肌麻痹23例,多发性麦粒肿4例。
Results:59 cases represented decrease of visual acuity. Among them, there were 44 cases of diabetic retinopathy and 15 cases of ametropia caused by change of plasma glucose.
