目的 :活体测量成年男性正视眼的前后径与横径。方法 :采用 CT方法 ,对成年男性 45人 73只正视眼的前后径与横径的内外径进行了活体测量 ,并对其中 2 3人 33眼的眼轴同时进行 A超测量。结果 :CT测量 ,前后径外径为 2 4.86± 1.0 9mm,内径为 2 2 .31± 1.2 2 mm,横径外径为 2 4.98± 1.2 5 mm,内径为 2 2 .5 8± 1.2 3mm,前后径与横径的外径与外径 ,内径与内径相比 ,均无显著性差异 (均 P>0 .0 5 )。A超测量眼轴为 2 3.0 2± 0 .75 mm。成年男性正视眼基本呈圆形。 CT与 A超测量方法不同 ,结果各异。结论 :活体 CT测量眼球径可靠、可行。尤对横径测量。在眼球形态学的意义上 ,提供了一个有价值的探索途径
OBJECTIVE: To measure the anteroposterior diameter and transverse diameter of adult eyes in adults. Methods: CT images were used to measure the anteroposterior diameter and transverse diameter of 45 adult men in 45 eyes. The axial length of 33 eyes of 23 males was measured by A-ultrasound at the same time. Results: CT measurement of the anteroposterior diameter of 2 4.86 ± 1.0 9mm, an internal diameter of 22.31 ± 1.2 2 mm, transverse diameter of 2 4.98 ± 1.2 5 mm, an internal diameter of 2 2 .5 8 ± 1.2 3mm, Before and after the diameter and diameter of the outer diameter and outer diameter, inner diameter and inner diameter compared to no significant difference (P> 0.05). The A-axis measurement was 2 3.0 2 ± 0 .75 mm. Adult male square eyes are basically round. CT and A different measurement methods, the results vary. Conclusion: The live eye CT measurement is reliable and feasible. Especially on the diameter measurement. In the sense of eye morphology, it provides a valuable exploration path
