Abstract

Objective: To study the correlation between episcleral vein pressure (EVP) with intraocular pressure (IOP), exophthalmos, and optic nerve injury in thyroid-associated ophthalmopathy (TAO) patients and to explore the possibility of higher EVP as an intervention indicator in TAO patients.

Methods: This study was a case-control study, including the TAO group and normal control group. TAO group: 15 patients (30 eyes) were diagnosed with TAO complicated with exophthalmos. Normal control group: 14 cases, 28 eyes. EVP, IOP, exophthalmos, retinal nerve fiber layer thickness, and visual field were measured, respectively in the two groups. Non-parametric test was used to compare the difference between EVP and IOP between the two groups, test the correlation between EVP and IOP or exophthalmos, and analyze the clinical characteristics of optic nerve injury in patients with elevated IOP in the TAO group.

Results: The EVP in the TAO group (15.30±3.48 mmHg) was significantly higher than the normal control group (8.82±1.44 mmHg) (P < .001). The IOP in the TAO group (18.55±8.13 mmHg) was significantly higher than in the normal control group (12.98±2.10 mmHg) (P < .001) (3) There was a positive linear correlation between EVP (X) and IOP (Y) in TAO group: Y = 0.9684x + 3.737 (rs>0, P < .05); There was a positive linear correlation between EVP (Y) and exophthalmos (X) in TAO group: Y = 0.9218x - 2.691 (rs>0, P < .05); Some TAO patients with elevated EVP had the related manifestations of optic nerve function impairment: thinning of retinal nerve fiber layer and loss of visual field. However, there was no clear correlation between EVP and the thickness of the optic nerve fiber layer (P = .4354).

Conclusion: The increase of EVP is an important factor leading to elevated IOP in TAO patients, which may be used as an indicator for intervention treatment in TAO patients. EVP can be used to indirectly evaluate orbital pressure. TAO patients can develop secondary glaucoma with irreversible optic nerve damage due to the continuous Elevation of EVP.

TAO患者巩膜外静脉压与眼压相关性的初步研究及其临床价值

目的研究甲状腺相关性眼病（TAO）患者的巩膜外静脉压（EVP）与眼压（IOP）、眼球外翻和视神经损伤之间的相关性，并探讨将较高的EVP作为TAO患者干预指标的可能性：本研究为病例对照研究，包括 TAO 组和正常对照组。TAO组15名患者（30只眼）被诊断为TAO并发眼球外翻。正常对照组14例，28眼。分别测量两组患者的EVP、眼压、眼球外凸、视网膜神经纤维层厚度和视野。采用非参数检验比较两组间EVP与眼压的差异，检验EVP与眼压或眼球外凸的相关性，并分析TAO组眼压升高患者视神经损伤的临床特征：TAO组的EVP（15.30±3.48 mmHg）明显高于正常对照组（8.82±1.44 mmHg）（P < .001）。TAO 组的眼压（18.55±8.13 mmHg）明显高于正常对照组（12.98±2.10 mmHg）（P < .001) (3) TAO 组的 EVP（X）与眼压（Y）呈正线性相关：Y=0.9684x+3.737（rs＞0，P＜0.05）；TAO组EVP（Y）与眼球外凸（X）呈正线性相关：Y=0.9218x-2.691（rs＞0，P＜0.05）；部分EVP升高的TAO患者有视神经功能损害的相关表现：视网膜神经纤维层变薄和视野缺损。然而，EVP与视神经纤维层厚度之间没有明显的相关性（P = .4354）：结论：EVP的增加是导致TAO患者眼压升高的一个重要因素，可作为TAO患者干预治疗的一个指标。EVP可用于间接评估眼眶压力。由于EVP持续升高，TAO患者可能发展为继发性青光眼，造成不可逆的视神经损伤。

期刊介绍： Launched in 1995, Alternative Therapies in Health and Medicine has a mission to promote the art and science of integrative medicine and a responsibility to improve public health. We strive to maintain the highest standards of ethical medical journalism independent of special interests that is timely, accurate, and a pleasure to read. We publish original, peer-reviewed scientific articles that provide health care providers with continuing education to promote health, prevent illness, and treat disease. Alternative Therapies in Health and Medicine was the first journal in this field to be indexed in the National Library of Medicine. In 2006, 2007, and 2008, ATHM had the highest impact factor ranking of any independently published peer-reviewed CAM journal in the United States—meaning that its research articles were cited more frequently than any other journal’s in the field. Alternative Therapies in Health and Medicine does not endorse any particular system or method but promotes the evaluation and appropriate use of all effective therapeutic approaches. Each issue contains a variety of disciplined inquiry methods, from case reports to original scientific research to systematic reviews. The editors encourage the integration of evidence-based emerging therapies with conventional medical practices by licensed health care providers in a way that promotes a comprehensive approach to health care that is focused on wellness, prevention, and healing. Alternative Therapies in Health and Medicine hopes to inform all licensed health care practitioners about developments in fields other than their own and to foster an ongoing debate about the scientific, clinical, historical, legal, political, and cultural issues that affect all of health care.
