青壮年近视患者的眼压变化及其规律探讨

目的 :探讨青壮年近视患者的眼压变化及其变化规律。方法 :对 46 6例 ( 891眼 )年龄在 16岁～ 46岁、屈光度从 -0 5 0D～ -2 3 5 0D的近视患者的眼压及其相关因素进行统计分析并与非近视组对照。结果 :近视患者眼压水平随屈光度增加而升高 (P <0 0 0 5 ) ;近视组平均眼压较非近视组高约 0 9mmHg ( 1mmHg =0 133kPa) ,高度近视组较非近视组高约 1 3mmHg ;不论中、低度近视还是高度或超高度近视其平均眼压水平均高于非近视组 (P <0 0 5 ) ;在近视组内 ,中、低度近视的平均眼压与高度或超高度近视之间有显著性差异 (P <0 0 5 ) ,但中度与低度近视之间、高度与超高度近视之间无明显差异。屈光度从 0D增加到 >8D时 ,眼压均值上升辐度大 ,净升值高达 1 2 7mmHg ,屈光度从 -8D上升到 -12D时 ,眼压均值升辐小 ,净升值低 ,仅 0 14mmHg。近视男性眼压高于女性 (P =0 0 0 0 1)。近视眼压与年龄及眼别无显著相关性。结论 :平均眼压随屈光度增加而升高 ,应加强对近视患者的眼压监测 ,对男性患者更为重要 ,降低眼内压也许是控制近视发展的一个重要手段

A tendency of IOP in the adult with myopia

Objective:To study the tendency of IOP in the young adults with myopia. Methods:The IOP value and other correlation factors from 466 cases(891 eyes)of myopia,ranged from 16 to 46 years old and from -0 50D to -23 50D in refractive power,were statistically analyzed and compared with non myopic group. Results:The IOP level of myopic patients went up with diopter increasing(P<0 005).The average value of IOP in myopic group was 0 9mmHg and in high myopic group was 13mmHg higher than that in non myopic group.The average IOP level in myopic group was higher than that in non myopic group,whether myopia was middle and low or high and extreme high(P<0 05).In myopic group,the average IOP value of high and extreme high myopic patients was higher than that of middle and low myopic ones(P<0 05)but there were no differences between middle and low myopia and between high and extreme high myopia.When the diopter rose from 0 0D to -8 0D,an elevatory extent of the average IOP value was greater and net increase value was 1 27mmHg.However,when the diopter rose from -8D to -12D,the average IOP value increased 0 14mmHg only.The IOP level in male was extremely higher than female(P<0 0001),but there was no differences in age or in eye distinction.Conclusions:Because the average IOP value rises gradually with diopter increasing,the IOP of myopic patients should be supervised strongly,especially in male.Reducing IOP may be an important means that controls myopia improvement.
