目的:使用OCT研究中心凹旁玻璃体视网膜牵引与慢性弥漫性黄斑水肿或囊样黄斑水肿的关系。方法:分析2例与中心凹旁玻璃体牵引膜相关的持续性弥漫黄斑水肿或持续性弥漫黄斑水肿伴黄斑囊样水肿患者的病历及OCT表现。患有其它玻璃体视网膜病变可能影响分析的,玻璃体切除术后的,或者经玻璃体腔内注射药物治疗的患者除外。年龄相匹配的正常对照组(n=12)的OCT用作正常黄斑厚度的定量标准。结果:患者1例1眼为眼球穿通伤后,另1例患者(1眼)为特发性慢性黄斑,常规治疗无效,经检查发现与中心凹旁玻璃体视网膜牵引有关。每只眼牵引位置下的视网膜水肿与黄斑中心水肿相连,因而表现为弥漫性黄斑水肿。OCT自动中心6条辐射线程序发现1眼的牵引位置,另1眼的诊断需要借助附加的线条组程序。结论:慢性弥漫性黄斑水肿可能与中心凹旁玻璃体视网膜牵引相关。为了发现中心凹旁牵引位置,应该使用不同的OCT程序仔细查找。为了比较早期玻璃体切除或药物玻璃体溶解术与现有的治疗方法的疗效还需要进一步的研究和大样本队列研究。
OBJECTIVE: To study the relationship between central vitreoretinal traction and chronic diffuse macular edema or cystoid macular edema using OCT. METHODS: The medical records and OCT findings of 2 patients with persistent diffuse macular edema or persistent macular edema with macular cystoid edema associated with the vitreoretinal traction membrane were analyzed. Patients with other vitreoretinal lesions who may be affected by the analysis, except after vitrectomy or with intravitreal injection. OCT of age-matched normal control group (n = 12) was used as a quantitative standard for normal macular thickness. Results: One patient (1 patient) had penetrating trauma and the other patient (1 patient) had idiopathic chronic macular degeneration. The conventional treatment was ineffective. It was found to be related to the traction of the parafoveal vitreoretinal. Retinal edema in each eye traction location associated with macular edema, which showed diffuse macular edema. OCT automatic center six radiation program found a traction position of the eye, the other one need to diagnose the use of additional line group procedures. Conclusion: Chronic diffuse macular edema may be related to the traction of the foveal vitreoretinal. In order to find the foveal towing position, you should look carefully using different OCT procedures. In order to compare the curative effect of early vitrectomy or drug vitreous lysis with the existing treatment methods, further studies and large sample cohort studies are needed.
