摘　　要：目的了解不同特征近视人群角膜光密度(COD)特点。方法对新疆维吾尔自治区人民医院2020年6月至2021年8月就诊的150例近视患者COD进行回顾性分析。统计患者的一般资料、屈光度、COD,比较分析不同屈光度、性别、民族COD特点。结果低度近视组角膜前层区域>6~10 mm高于中、高度近视组,差异有统计学意义(P<0.05)。不同性别不同角膜区域COD值比较,差异无统计学意义(P>0.05)。维吾尔族前层区域、中央区域、后层区域的同心环形区(直径0~2、>2~6、>6~10 mm)、总直径(0~12 mm)COD低于汉族;维吾尔族全层区域直径0~2、>6~10 mm及总直径0~12 mm的COD低于汉族,差异有统计学意义(P<0.05)。结论不同近视人群的COD可能不同,为进一步研究近视人群角膜生物特性提供依据。Objective To understand the corneal optical densitometry(COD)density characteristics of different myopia patients.Methods The COD of 150 patients with myopia treated in People’s Hospital of Xingjiang Uygur Autonomous Region from June 2020 to August 2021 was analyzed retrospectively.The general data,diopter,and COD of patients were counted,and the COD characteristics of different diopters,genders,and nationalities were compared and analyzed.Results The anterior corneal layer area>6-10 mm in low myopia group was higher than that in moderate and high myopia group,and the difference was statistically significant(P<0.05).There was no significant difference in COD value between different genders and different corneal areas(P>0.05).The COD of the concentric ring zone(diameter 0-2,>2-6,>6-10 mm)and the total diameter(0-12 mm)in the front,central and back layers of the Uygur were lower than that of the Han nationality;COD in the whole-layer area with diameters of 0-2,>6-10 mm and the total diameter of 0-12 mm were lower than those in the Han nationality,and the differences were statistically significant(P<0.05).Conclusion The COD of different myopic people may be different,which provides a basis for further study of corneal biological characteristics of myopic people.
