To investigate the relationship between the size of the peripapillary crescent and different ocular parameters in highly myopic healthy eyes; in addition, to determine whether the area of the peripapillary crescent enlarged significantly during one year of observation.
The medical records of 49 highly myopic healthy eyes whose fellow eyes had myopic complications were reviewed. The area of the peripapillary crescent and other ocular parameters were measured initially and after one year. The changes in the area of the peripapillary crescent and their association with other ocular parameters during the natural course of the pathological myopia were determined.
The area of the peripapillary crescent was significantly associated with the choroidal thickness (P < 0.001), axial length (P < 0.001), and foveal thickness (P < 0.01). Stepwise regression analyses found that the factors most associated with the area of the peripapillary crescent were the choroidal thickness (P < 0.01) and the absolute nasal staphyloma height (P < 0.05). The factor most associated with the increase in the area of the peripapillary crescent was the increase in the axial length (P < 0.01).
The size of the peripapillary crescent may be affected by changes in the axial length, the height of the posterior staphyloma, and the choroidal thickness.
探讨高度近视健康眼中视乳头周围新月形区大小与不同眼部参数之间的关系；此外，确定在一年的观察期间视乳头周围新月形区的面积是否显著增大。
回顾了 49 只高度近视健康眼的病历，这些眼的对侧眼有近视并发症。最初和一年后测量视乳头周围新月形区的面积和其他眼部参数。确定视乳头周围新月形区的面积在病理性近视的自然病程中的变化及其与其他眼部参数的关系。
视乳头周围新月形区的面积与脉络膜厚度（P<0.001）、眼轴长度（P<0.001）和黄斑中心凹厚度（P<0.01）显著相关。逐步回归分析发现，与视乳头周围新月形区面积最相关的因素是脉络膜厚度（P<0.01）和绝对鼻侧巩膜隆突高度（P<0.05）。与视乳头周围新月形区面积增加最相关的因素是眼轴长度的增加（P<0.01）。
视乳头周围新月形区的大小可能受到眼轴长度、后巩膜隆突高度和脉络膜厚度变化的影响。
