AIM: To explore the factors of macular parameters in the patients with the different degrees of myopia.

METHODS: Totally 313 myopia patients who volunteered to participate in the study were selected and divided into mild, moderate and severe myopia groups. Optical coherence tomography(OCT)was used to measure the central area of the macula thickness, the temporal, upper, nasal and lower areas of the inner and outer ring. And the correlation between the macular parameters and age, gender, different of eyes, axial length and spherical equivalent were analyzed.

RESULTS: The central fovea of macula was the thinnest. The superior and the nasal of inner ring were the thinner among all parts of macular and there were significant differences in macular thickness among three groups(P<0.05). Correlation analysis showed that there was no correlation between the macular thickness and age, different of eyes(P>0.05). Macular thickness in different areas were correlated with gender, and the thickness in women was thinner than men(P<0.05). The macula thickness in all areas of the inner and outer ring was negatively correlated with axial length except the center(P<0.05). The macula thickness in all areas of the inner and outer ring positively correlated with spherical equivalent except the center(P<0.05).

CONCLUSION: The macular parameters of myopia were closely linked to the spherical equivalent and axial length.
