Abstract:
AlM: To measure ocular biometric values with the degree of axial myopia and determine the relationship between the differences using the Lenstar 900.
METHODS:Totally 413 myopes (826 eyes) were enrolled in this study and were divided into 3 groups: low myopia (myopia <3. 00 diopters, 104 eyes), moderate myopia ( myopia =3. 00-6. 00 diopters, 500 eyes) and high myopia ( myopia > 6. 00 diopters, 222 eyes ). Central corneal thickness ( CCT ) , aqueous depth ( AD ) , lens thickness (LT), axial length (AL) were measured by Lenstar 900. The parameters were tested using analysis of variance and the relations among SE, AL, LT were analyzed.
RESULTS: There were significant difference both in AL (F=206.16, P<0.01) and AD (F=4.764, P<0.05) and no significant difference both in CCT and LT between these myopia groups. With analysis of Person, the Spherical equivalent ( SE) shows a significantly positive correlation with AL (r=0. 662, P<0. 01) and AD (r=0. 095, P<0. 05), no correlation with CCT and LT. AL shows a significantly positive correlation with AD (r=0. 347, P<0. 01) and CCT (r=0.126, P<0.01), negative correlation with LT (r=-0.265, P<0. 01). LT shows a significantly negative correlation with AD (r=-0. 496, P<0. 01).
CONCLUSlON: Along with the diopters increasing in myopia, the axial length and aqueous depth continue to increase. Spherical equivalent ( SE) shows a significantly positive correlation with AD. AL shows positive correlation with SE, AD and CCT and negative correlation with LT. LT shows a significantly negative correlation with AD.
