PURPOSE
To study the morphologic alterations around the optic disc by spectral optical coherence tomography (SD OCT) in eyes with high myopia.
PATIENTS AND METHODS
Two hundred eyes (113 patients) with high myopia were included. The participants had complete ophthalmologic examinations and OCT examinations. OCT scans were obtained around the optic in each patient.
RESULTS
We detected by OCT, a peripapillary detachment in 14 eyes (11.0%), a retinischisis peripapillary in 10 eyes (5%) and paravascular abnormalities as microfolds and paravascular cysts in 80 eyes (40%). A statistically significant difference was found between patients with microfolds paravascular and the rest of the patients concerning age (P=0.0034) and axial length (P=0.001). The patients with paravascular cysts were older (P=0.0022), had a greater axial length (P=0.0044) and a high rate of posterior staphyloma compared to other patients.
CONCLUSION
Perpapillary changes detected by SD OCT in eyes in high myopia are relatively frequent and don't always present a clinical or ophthalmoscopic changes.
目的
通过光谱光学相干断层扫描（SD OCT）研究高度近视眼中视盘周围的形态学改变。
患者与方法
纳入200只高度近视眼（113例患者）。参与者接受了完整的眼科检查和OCT检查。对每位患者的视盘周围进行了OCT扫描。
结果
通过OCT我们检测到，14只眼（11.0%）存在视乳头周围脱离，10只眼（5%）存在视乳头周围视网膜劈裂，80只眼（40%）存在血管旁异常，如微褶皱和血管旁囊肿。血管旁微褶皱患者与其他患者在年龄（P = 0.0034）和眼轴长度（P = 0.001）方面存在统计学显著差异。与其他患者相比，血管旁囊肿患者年龄更大（P = 0.0022），眼轴长度更长（P = 0.0044），后巩膜葡萄肿发生率更高。
结论
SD OCT检测到的高度近视眼中视乳头周围改变相对常见，且并不总是伴有临床或检眼镜改变。
