目的：目的：探讨单侧视乳头周围脉络膜内空洞（PICCs）患者的视乳头形态学改变。方法：以医院为基础的观察性研究包括单侧PICCs患者。采用光学相干断层扫描的增强深度成像模式，获取瞳孔旁眼底的断层图像。结果：研究人群包括30例患者，平均年龄42.7 ± 13.8岁（范围：22-72岁），平均轴长26.7 +/- 2.4 mm（范围：22.00-32.30 mm），平均屈光不正为-8.71 +/-5.21屈光度（范围：-20.50至+0.50屈光度）。与对侧眼相比，PICC患眼的垂直（P = 0.001）和最小视盘直径（P = 0.01）明显缩短，最小与最大椎间盘直径的比值明显降低（P = 0.03），椎间盘旋转角度显著高于（P < 0.001）。单侧PICCS患者，由于视盘围绕垂直轴和矢状轴旋转，与对侧眼相比，
Purpose: To examine the morphology of the optic nerve head in patients with unilateral peripapillary intrachoroidal cavitations (PICCs).Methods: The hospital-based observational study included patients with unilateral PICCs. Tomographic images of the parapapillary fundus were taken by enhanced depth imaging mode of optical coherent tomography. The ocular biometric parameters were compared between the affected eyes and the contralateral unaffected eyes.Results: The study population consisted of 30 patients with a mean age of 42.7 +/- 13.8 years (range: 22-72 years), mean axial length of 26.7 +/- 2.4 mm (range: 22.00-32.30 mm), and mean refractive error of -8.71 +/- 5.21 diopters (range: -20.50 to +0.50 diopters). In the eyes affected by PICC as compared with the contralateral eyes, the vertical (P = 0.001) and the minimal optic disk diameters (P = 0.01) were significantly shorter, the ratio of minimal to maximal disk diameter was significantly lower (P = 0.03), and the angle of disk rotation was significantly higher (P < 0.001).Conclusion: In patients with unilateral PICCS, the eyes with PICCs had optic disks that were more spindlelike configured because of a disk rotation around the vertical axis and around the sagittal axis as compared with the contralateral eyes.
