Relationship of different diopter of myopic eyes and gender with central corneal thickness,corneal curvature and intraocular pressure

AIM:To investigate the relationship of different diopter of myopic eyes and gender with central corneal thickness(CCT),corneal curvature(k1 and k2) and intraocular pressure(IOP).METHODS:CCT,k1,k2 and IOP of 1108 patients(2189 eyes) were measured and the data were divided respectively into 3 groups according to different diopter and into 2 groups according to different gender.RESULTS:Significant difference was observed between low myopy group[(541±36) μm],medium myopy group[(535±32)μm] and high myopy group[(535±40)μm] in CCT(P0.05).The value of k1[(43.1±1.5)D] and k2[(44.4±1.6)D] of high myopy were significant higher than those of medium myopy group and low myopy group(P0.05).the IOP of low myopy[(16.5±3.1)mmHg] was significantly higher than that of high myopy group[(16.0±3.0)mmHg,P0.05].The CCT value of male[(539±37)μm] was significantly higher than that of female[(534±32)μm] but k1[(42.7±1.5)D] and k2[(43.8±1.6)D] of males were lower than those of female[k1(43.3±1.4)D,k2(44.5±1.5)D] respectively(P0.05).No significant difference was seen in IOP between genders.CONCLUSION:There exists difference in CCT,k1,k2 and IOP between different diopter myopic eyes or genders.
