【摘要】： 玻璃体后脱离(posterior vitreous detachment, PVD)是指玻璃体后皮质与视网膜内界膜之间的分离。近视眼的PVD较为多见。准分子激光原位角膜磨镶术(laser in situ keratomi leusis, LASIK)用于近视矫治已经在全世界广泛开展,LASIK手术是否存在对玻璃体和视网膜的影响在临床上越来越引起重视。傅里叶域光学相干断层扫描(Optical coherence tomography, OCT)具有分辨率高,扫描速度快的优点。本课题拟通过傅里叶域OCT研究近视眼患者的PVD发生情况以及LASIK手术与PVD的关系。本文进行了以下两个方面的研究：一、近视眼患者的早期玻璃体后脱离目的：评估近视眼患者早期玻璃体后脱离的发生情况。方法：对37例(73眼)近视和近视散光的患者采用OCT及眼部B超检查,观察其PVD发生情况。结果：本组患者OCT显示早期PVD发生率为47.9%,而B超未显示PVD。Logistic回归分析显示女性是发生早期PVD的危险因素。结论：本年龄组近视眼患者部分性PVD发生率高,鼻上象限最多见。女性可能是发生早期PVD的危险因素。OCT是目前诊断早期PVD最有效的方法,可以在临床上推广应用。二、近视眼患者LASIK术后玻璃体后脱离的临床观察目的：评估近视眼患者行准分子激光原位角膜磨镶术后PVD的发生情况。方法：对37例(73眼)在我院行LASIK矫治近视和近视散光的患者采用OCT及眼部B超检查,观察其术前与术后第10天、第1、第3个月的PVD发生情况。结果：术后3个月随访中没有发现新发生的PVD及原有PVD的扩大,未观察到玻璃体黄斑牵引综合征、视网膜裂孔等眼后段并发症。结论：LASIK手术不会明显导致PVD。LASIK手术前后用OCT动态监测玻璃体视网膜界面,有助于及时发现PVD及其他病变的发生发展。
[Abstract]:The posterior vitreous detachment (PVD) refers to the separation between the posterior cortex of the vitreous and the inside of the retina. PVD of myopia is more common. Laser in situ keratomileusis (LASIK) is widely used in the treatment of myopia. Optical coherence tomography (OCT) has the advantages of high resolution and high scanning speed. This paper is to study the occurrence of PVD in patients with myopia and the relationship between LASIK and PVD by means of Fourier domain OCT. In this paper, the following two aspects are carried out The study of the patients with myopia and myopia The purpose of early vitreous detachment: to evaluate the early stage of myopia Methods: OCT and eyes were used in 37 patients (73 eyes) of myopia and myopic astigmatism. The results showed that the incidence of early PVD was 47.9% and that of B-ultrasound did not show PVD and Logistic regression. Analysis shows that women are a risk factor for early PVD. Conclusion: This age group The incidence of partial PVD in the patients with myopia is high, and the upper part of the nose The most frequently seen in the quadrant. Women may be a risk factor for early PVD. OCT is the current visit The most effective method of early-stage PVD can be applied clinically. The Clinical Observation of the Posterior Vitreous Detachment of the Patients with Myopia after LASIK Objective: To evaluate the incidence of laser in situ keratomileusis (PVD) after laser in situ keratomileusis in patients with myopia. In the follow-up of 3-month follow-up, no newly-occurring P was found in the follow-up of the 3-month follow-up. The enlargement of VD and the original PVD did not observe the complications of vitreous macular traction syndrome, retinal tears, etc. Conclusion: LASIK operation does not significantly result in PVD.
