目的:探讨玻璃体内注射丙酮化曲安奈德用于治疗视网膜中央静脉阻塞(CRVO)引起黄斑水肿的安全性和有效性。方法:在Wisconsin大学和Bascom Palmer眼科研究所.对13例(13只眼)连续的CRVO引起黄斑水肿的患者应用玻璃体内注射丙酮化曲安奈德(4mg)治疗.回顾研究其病历记录。每次玻璃体内注射时应用27G或30G针头通过睫状体平坦部注射。主要结果测量:Snellen视力的变化、黄斑水肿的临床表现、应用光学相干断层扫描仪(OCT)测量中心凹的增厚以及并发症的出现频率。结果:13例患者的平均年龄为67岁(四分位数间距为57—77岁).注射前症状的平均持续时间为8个月(四分位数间距为4—9个月)。患眼在初诊时的平均视力为20/500.在6个月随诊检查时的平均视力为20/1踟。所有13例患者都完成了6个月的随诊检查。非缺血型CRVO患眼(n=5)的视力有显著的提高.而缺血型CRVO患眼(n=8)没有显著的视力提高。患者没有出现视力下降。初诊时OCT测量的平均中心凹厚度为590μm(视网膜增厚=416μm)。12例患者在1个月随诊检查时OCT测量的平均中心凹厚度为212pm(视网膜增厚=38μm)。13例患者在3个月随诊检查时OCT测量的平均中心凹厚度为193μm(视网膜增厚=19μm)。在3和6个月随诊检查之间.4例患者的黄斑水肿复发.其中3例患者再次接受了曲安奈德的注射。这3例患者中的2例经过再次治疗视力提高。在6个月随诊检查时.13例患者OCT测量的平均中心凹厚度为281μm(视网膜增厚=107μm)。没有发生视网膜脱离或眼内炎等并发症。1例患者出现了眼压的升高.应用2种房水生成抑制剂治疗得以控制。结论:在部分CRVO引起黄斑水肿的患者中.玻璃体内注射曲安奈德可能是一种有效的治疗方法。与缺血型CRVO患者相比.非缺血型CRVO患者可以获得更令人满意的效果。部分患者可能需要重复治疗。在本组患者中未发现严重的并发症。 相似文献

Optical coherence tomography (OCT) has improved the understanding and management of idiopathic macular hole. Images of precursor lesions and their progression demonstrate that antero-posterior as well as tangential traction are involved in macular hole formation. The staging of macular holes with biomicroscopic examination can be paralleled by optical coherence tomography staging with some modification. OCT is useful in differentiating simulating lesions and in allowing better counseling of patients regarding their disorder. Finally, OCT findings are prognostic of surgical success and can assist in evaluating the results of surgery. 相似文献

The introduction of new technologies into small remote communities can alter how individuals acquire knowledge about their surrounding environment. This is especially true when technologies that satisfy basic needs, such as freshwater use, create a distance (i.e., diminishing exposure) between individuals and their environment. However, such distancing can potentially be countered by the transfer of local knowledge between community members and from one generation to the next. The objective of this study is to simulate by way of agent-based modeling the tensions between technology-induced distancing and local knowledge that are exerted on community vulnerability to climate change. A model is developed that simulates how a collection of individual perceptions about changes to climatic-related variables manifest into community perceptions, how perceptions are influenced by the movement away from traditional resource use, and how the transmission of knowledge mitigates the potentially adverse effects of technology-induced distancing. The model is implemented utilizing climate and social data for two remote communities located on the Seward Peninsula in western Alaska. The agent-based model simulates a set of scenarios that depict different ways in which these communities may potentially engage with their natural resources, utilize knowledge transfer, and develop perceptions of how the local climate is different from previous years. A loosely-coupled pan-arctic climate model simulates changes monthly changes to climatic variables. The discrepancy between the perceptions derived from the agent-based model and the projections simulated by the climate model represent community vulnerability. The results demonstrate how demographics, the communication of knowledge and the types of 'knowledge-providers' influence community perception about changes to their local climate. 相似文献
