目的:探讨不同注视角度下眼的调节幅度、前房深度、晶状体厚度、眼轴长度的变化。方法:对18例36眼21～28岁的志愿者,取与重力轴方向成180°,90°,45°夹角的3个不同注视角度,用移近法测量眼的调节幅度,用眼A超测量前房深度、晶状体厚度、眼轴长度。结果:三种不同注视角度下的调节幅度、前房深度、晶状体厚度、眼轴长度无差异。结论:在青年中,眼在仰视、平视、俯视状态不影响其调节幅度、前房深度、晶状体厚度、眼轴长度。

AIM:To investigate the change of accommodation,anterior chamber depth,lens thickness,axial length in different stare angles. METHODS:Eighteen volunteers(36 eyes) aged 21 to 28 took measurements with different angles of stare,180°,90°,45° from gravity axis respectively,the accommodation was measured by push-up test,and anterior chamber depth,lens thickness,axial length were measured by A-ultrasonic.RESULTS:There were no significant difference in accommodation,anterior chamber depth,lens thickness,axial length in different stare angles. CONCLUSION:Different angles of stare can not influence the accommodation,anterior chamber depth,lens thickness and axial length in young people.
