【摘要】：目的调查云南省大理市农村白族人口中50岁及以上正常人群的眼压分布特征及眼压的相关因素分析。方法 2010年1月-2010年2月,采用整群随机抽样方法将大理市分为259个抽样点(每个点人数约为1000人),随机抽取其12个,对所有50岁及以上受试者人群进行视力和眼部检查。在大理白族50岁及50岁以上人群中共检录2742例拟定受试者,其中有2133位受试者参与完成了视力、眼压及眼部调查,视力检查采用糖尿病视网膜病变早期治疗研究视力表测定生活视力及最佳矫正视力,眼压检查选用TONO-PEN压平式眼压计,由眼科医师进行外眼、前房、晶体、眼底及眼压、中央角膜厚度、前房深度等检查,眼压(intraocular pressure IOP)21mmHg的受检者进入青光眼排查。眼压与年龄、性别、眼轴长度、中央角膜厚度之间的关系采用相关因素分析。结果在这次的调查研究中,共检录2742人,实际调查2133人,实际接受调查的男、女人数分别为769人和1364人,总受检率为77.8%。调查人群的平均年龄是64.48±8.91岁,最小的是50岁,最大的是91岁,其分布图呈正偏态分布。全部调查人群中,男性的平均眼压是14.70±3.44mmHg,女性的平均眼压是14.44±3.31mmHg,并测得总平均眼压值是14.45±3.35mmHg,最小值是6mmHg,最大值是51 mmHg,其分布图呈正态分布。统计分析相关性结果为：在50岁及以上白族人群中,眼压和年龄之间没有相关性(r=-0.003,P=0.849)；眼压和中央角膜厚度之间关系密切(r=0.118,P0.001),分析结果显示,眼压和眼轴长度、低视力之间没有明显相关性。结论：在50岁及以上白族人群中,眼压和年龄,性别,眼轴长度之间没有相关性,眼压明显受中央角膜厚度(central corneal thickness CCT)的影响。IOP随CCT增加而增高并成正相关,与近视屈光度无关。CCT为影响IOP检测的一个重要因素,检查CCT有助于更正确地估计IOP,可以作为鉴别某些临床疾病的重要指标。
[Abstract]:Purpose To investigate the distribution of intraocular pressure (IOP) and the related factors of intraocular pressure (IOP) in the population of Bai nationality aged 50 years and over in Dali, Yunnan Province. Method From January 2010 to February 2010, Dali city was divided into 259 sampling points by cluster random sampling (the number of each point was about 1000 people), 12 of them were randomly selected, and the visual acuity and eye examination were performed on all subjects aged 50 and above. A total of 2742 subjects aged 50 and over were examined in the Bai nationality of Dali, and 2133 of them participated in the investigation of eyesight, intraocular pressure and eyes. The visual acuity and best corrected visual acuity were measured by visual acuity chart. The intraocular pressure (IOP) was examined by TONO-PEN pressure level IOG, and the external eye, anterior chamber, lens, fundus and intraocular pressure were performed by ophthalmologist. Central corneal thickness and anterior chamber depth were examined. Intraocular pressure IOP)21mmHg patients were examined for glaucoma. The relationship between IOP and age, sex, axial length and central corneal thickness was analyzed. Result In this investigation and study, a total of 2742 people were recorded and 2133 were actually investigated. The actual number of men and women were 769 and 1364, respectively, with a total rate of 77.8%. The average age was 64.48 卤8.91 years old, the youngest was 50 years old and the largest was 91 years old. The mean IOP was 14.70 卤3.44mmHg in males and 14.44 卤3.31mmHg in females. The mean IOP was 14.45 卤3.35mmHg, the minimum was 6mmHgand the maximum was 51mmHg.The distribution of IOP was normal distribution. The results of statistical analysis were as follows: there was no correlation between IOP and age in Bai people aged 50 and over, and there was a close relationship between IOP and central corneal thickness. The results showed that IOP and length of ocular axis were closely related to the thickness of central cornea. There was no significant correlation between low vision. Conclusion: there was no correlation between IOP and age, sex, eye axis length in Bai people aged 50 or over. IOP was significantly affected by central corneal thickness CCT). IOP increased with the increase of CCT. CCT-independent of myopic diopter is an important factor affecting the detection of IOP. The examination of CCT is helpful to estimate IOPs more accurately and can be used as an important index to distinguish some clinical diseases.
