角膜镜

Methods(1)4 cities were chosen randomly according to their economic status and geographical location.(2)An autorefractor was used to detect the diopter in the preschool children from 20 kindergartens randomly selected from each of the 4 cities.(3)1%atropine ointment was applied to the c onjunctival sac of the children with suspect myopia for 3 days and the refractio n of light in their retina was then examined by a barred beam skiascope.(4)The eye axis and corneal curvature of the myopic children were measured.(5)The diop ter,eye axis,and corneal curvature were examined every 6 months during 1-year f ollow-up after the diopter was properly rectified.

(1)依经济状况和地理位置按随机原则抽取4市县；(2)从4市县中各随机选择20间幼儿园，对所抽取的在园学龄前儿童用自动屈光仪进行屈光筛查；(3)可疑近视患者予以1%阿托品眼膏涂双眼3d，由专人用带状检影镜进行视网膜检影验光；(4)确诊为近视的患者自愿进行角膜曲率和眼轴测量；(5)近视患者经适当的屈光矫正后，按要求进行为期1年的前瞻性随访，每半年进行1次屈光状态、角膜曲率和眼轴的检测。

RESULTS: The following changes were found under light microscopy in keratoconus:thin epithelium and stroma,local rupture or destruction in basement membranes and Bowman"s layer,basal cell swollen,stroma disarrangement,ruptures or folds in the Descemet"s membrane and thin endothelium layer.

结果 光镜观察结果，圆锥角膜上皮层、基质层变薄，基底膜及前弹力层局限性断裂或破坏，上皮基底细胞水肿，角膜基质排列紊乱，后弹力膜皱褶或断裂，内皮细胞变薄。

Methods One hunderd amd ten human subjects (one hunderd and seventy-four eyes) were included in this research. Retinoscopy was made to measure refractive errors, corneal topographer was measured by corneal topography system, Tonometry was used to measure IOP, Ultrasonagraphy was applied to measure anterior chamber length, len thickness and vitreous length respectively, Laser interference biometer was used to measure axial length, Optical coherence tomography was used to measure retina thickness of fovea area. Based on spherical equivalent subjects were divided into four groups: emmetropia group (SE0.50D), low-myopia group (-0.50D≤SE3.00D), moderate myopia group (-3.00D≤SE6.00D) and high myopia group (SE≥-6.00D).

对近视患者及正视者110例（174只眼），主觉加检影验光行屈光检查，采用Humphrey测量角膜平均曲率，非接触式眼内压测量仪测量眼内压；A与B型超声诊断仪测量前房深度、晶状体厚度、玻璃体腔长度及眼轴长度；角膜测厚仪测量中央角膜厚度(CCT，centercornealthickness)；光学相干生物测量仪测量眼轴长度；光学相干断层扫描仪测量黄斑中心视网膜厚度；按等效球镜度数(SE， sphericalequivalent)不同分正视组(SE0.05D)、轻度近视组(-0.50D≤SE3.00D)、中度近视组(-3.00D≤SE＜-6.00D)、高度近视组SE≥-6.00D）。
