Abstract：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.
