目的:使用光学相干断层扫描(OCT),我们评估了乳头周围视网膜神经纤维之间的关联,黄斑厚度,黄斑神经节细胞内丛状层,和抗药性。
方法:在这项横断面研究中,我们招募了被诊断为癫痫患者和健康对照者.癫痫患者根据他们对抗癫痫药物的反应被进一步分层为耐药或非耐药。进行OCT测量,并分析了右眼的发现。
结果:51名耐药参与者,37不耐药,纳入45名对照。平均乳头周围视网膜神经纤维层,神经节细胞内丛状层,癫痫组的黄斑厚度比对照组薄。耐药组的平均神经节细胞内丛状层厚度(p=0.004)和异常/临界GC/IPL厚度的比例(p=5.40E-04)明显低于非耐药组。然而,视网膜周围神经纤维平均厚度与黄斑厚度无明显差异。这三个参数的时间部分在耐药组中也明显比非耐药组中薄。在多元回归模型中,耐药性是神经节细胞内丛状厚度降低的独立预测因素(几率OR=10.25,95%CI2.82~37.28)。癫痫发作频率增加(r=-0.23,p=0.039)和使用过的抗癫痫药物数量增加(r=-0.27,p=0.013)与神经节细胞内丛状层厚度呈负相关。
结论:耐药癫痫患者的平均神经节细胞内丛状层厚度和颞部视网膜周围神经纤维层和黄斑厚度一致降低。这表明神经节细胞内丛状层厚度可能作为耐药性负担的指标,
结论:在我们的研究中,我们使用了一种称为OCT的特殊工具来测量癫痫患者和健康对照者的视网膜厚度。我们发现,与健康对照相比,癫痫患者的所有区域的视网膜始终更薄。特别是,在对药物没有反应的组中,一个称为神经节细胞内丛状层的特定层要薄得多,这种减少与癫痫发作的频率和服用多少药物有关。此外,耐药组中视网膜的某些部分较薄.
OBJECTIVE: Using Optical coherence tomography (OCT), we evaluated the association between peripapillary retinal nerve fiber, macular thickness, macular ganglion cell-inner plexiform layer, and drug resistance.
METHODS: In this cross-sectional study, we recruited people diagnosed with epilepsy and healthy controls. People with epilepsy were further stratified as drug-resistant or non-drug-resistant based on their response to anti-seizure medications. OCT measurements were conducted, and findings in right eye were analyzed.
RESULTS: Fifty-one drug-resistant participants, 37 non-drug-resistant, and 45 controls were enrolled. The average peripapillary retinal nerve fiber layer, ganglion cell-inner plexiform layer, and macular thickness were thinner in the epilepsy groups than in controls. The drug-resistant group had significantly lower average ganglion cell-inner plexiform layer thickness (p = 0.004) and a higher proportion of abnormal/borderline GC/IPL thickness (p = 5.40E-04) than the non-drug-resistant group. Nevertheless, no significant differences were seen between the average thickness of peripapillary retinal nerve fiber and macular thickness. The temporal sectors of these three parameters were also significantly thinner in the drug-resistant group than in the non-drug-resistant. In a multivariate regression model, drug resistance was an independent predictor of reduced ganglion cell-inner plexiform thickness (Odds ratios OR = 10.25, 95% CI 2.82 to 37.28). Increased seizure frequency (r = -0.23, p = 0.039) and a higher number of anti-seizure medications ever used (r = -0.27, p = 0.013) were negatively associated with ganglion cell-inner plexiform layer thickness.
CONCLUSIONS: Individuals with drug-resistant epilepsy had a consistent reduction in average ganglion cell-inner plexiform layer thickness and the temporal sector of peripapillary retinal nerve fiber layer and macular thickness. This suggests that ganglion cell-inner plexiform layer thickness could potentially serve as an indicator of the burden of drug resistance, as it correlated with reduced thickness in individuals having more frequent seizures and greater exposure to ASMs.
CONCLUSIONS: In our study, we used a special tool called OCT to measure how thick the retina is in people with epilepsy and in healthy control. We found that the retina was consistently thinner in all areas for those with epilepsy compared to healthy control. Particularly, a specific layer called the ganglion cell-inner plexiform layer was a lot thinner in the group that didn\'t respond to medications, and this thinning was related to how often seizures occurred and how much medications were taken. Also, certain parts of the retina were thinner in the drug-resistant group.
