目的 :探讨B超在近视眼巩膜后葡萄肿中的应用价值。方法 :用B型超声仪检查 >3.0 0D的 38例76眼进展性近视眼的巩膜后葡萄肿的发生情况。结果 :76眼中 5 8眼发生后葡萄肿。其中各级后葡萄肿的平均屈光度及眼轴差异均有非常显著性意义 (P <0 .0 1和P <0 .0 0 1)。 1～ 4级后葡萄肿与 0级葡萄肿的弧形斑发生率比较差异有非常显著性意义 (P <0 .0 1)。结论 :B超是诊断巩膜后葡萄肿最安全、快速、可靠的方法 ,对近视眼的预后判断有着重要作用。近视眼的屈光度和眼轴随巩膜后葡萄肿的加重而增加 ,眼底弧形斑的形成与后葡萄肿的形成有密切关系
Objective: To investigate the value of B-ultrasound in posterior scleral staphyloma of myopia. Methods: The incidence of posterior staphyloma of 38 cases of progressive myopia in 38 cases> 3.0 0D was examined by B - mode ultrasound. Results: Fifty-eight of 76 eyes developed post-staphyloma. Among them, the average refractive power and axial difference of posterior staphyloma at all stages were significant (P <0.01 and P <0.01). There was a significant difference in the incidence of arcuate plaques between grade 1 and grade 4 after 0 and grade 0 (P <0.01). Conclusion: B-ultrasound is the most safe, rapid and reliable method for the diagnosis of posterior scleral staphyloma and plays an important role in the prognosis of myopia. Refraction and ocular axial myopia with posterior scleral staphyloma increased aggravated, the formation of fundus arcuate plaques and the formation of post-staphyloma are closely related
