研究目的:

本研究通过探讨稳态视觉诱发电位(SSVEP)在青光眼诊断中的应用潜力,评估这种新型电生理测量手段在早期青光眼检测中的准确性、敏感性和特异性。我们将重点研究SSVEP参数在青光眼患者与健康对照组之间,和青光眼组内患者之间的差异 ,同时与传统的“金标准”H-F视野检查对比,并探讨其与传统诊断方法(如视野检查、OCT)之间的相关性。  

Objectives of Study:

This study aims to investigate the potential application of steady-state visual evoked potentials (SSVEPs) in the diagnosis of glaucoma, and to evaluate the accuracy, sensitivity, and specificity of this novel electrophysiological approach for the detection of early glaucoma. We will focus on differences in SSVEP-derived parameters between patients with glaucoma and healthy controls, as well as among patients within the glaucoma group. In addition, SSVEP findings will be compared with those obtained from conventional "gold-standard" Humphrey visual field testing, and their correlations with established diagnostic modalities, including standard automated perimetry and optical coherence tomography (OCT), will be explored.

Inclusion criteria

Glaucoma group 1. Diagnosis of glaucoma All participants in the glaucoma group must have a confirmed diagnosis of glaucoma based on the following criteria: 1) Optic nerve head assessment:The optic nerve head demonstrates typical glaucomatous changes, such as neuroretinal rim thinning/notching and peripapillary retinal nerve fiber layer (RNFL) thinning. 2) Optical coherence tomography (OCT): Thinning of the retinal nerve fiber layer is present. 3) Visual field testing: A glaucomatous visual field defect is confirmed, defined as at least three test points with sensitivity depressed at P < 0.05, with at least one point at P < 0.01 on the 24-2 test pattern, or a positive result on the Glaucoma Hemifield Test. 2. Visual function requirement All glaucoma patients must have a best-corrected visual acuity (BCVA) of ≥ 0.3 in the study eye. 3. Age requirement Participants must be between 18 and 80 years of age. 4. Severity of visual field loss On the 24-2 Humphrey visual field test, the mean deviation (MD) must not be worse than ?30 dB, indicating that visual field loss is not extremely advanced. 5. Intraocular pressure must be stable under treatment. 6. Participants must be able to understand and sign the written informed consent form. 7. Participants must be able to cooperate with steady-state visual evoked potential (SSVEP) testing. Healthy control group 1. Participants aged 18–80 years, with no restriction on sex. 2. No history of glaucoma or other ocular diseases. 3. Normal intraocular pressure, normal optic disc appearance, and normal visual field test results. 4. Best-corrected visual acuity ≥ 0.3. 5. Ability to understand and sign the written informed consent form.

排除标准:

(1)患者若有其他可能影响视力的眼科疾病(例如显著影响视力的白内障、黄斑病变等),将被排除; (2)患者若视力差,无法达到研究所要求的标准,亦会被排除; (3)如果患者有认知障碍或其他无法进行测试的情况,也会被排除。 (4)患有严重全身性疾病或神经系统疾病(如癫痫、中风、重度高血压、糖尿病视网膜病变等)。 (5)服用可能影响视觉功能或脑电生理药物。 (6)SSVEP记录过程中出现无法纠正的伪影。 (7)妊娠期或哺乳期女性。 (8)其他研究者认为不适合入组的情况。

Exclusion criteria:

1. Presence of other ocular diseases that may affect visual function, such as visually significant cataract, macular disorders, or other retinal diseases. 2. Best-corrected visual acuity that does not meet the predefined study requirements. 3. Cognitive impairment or any other condition that precludes reliable completion of the examinations. 4. Presence of severe systemic or neurological diseases, including but not limited to epilepsy, stroke, severe hypertension, or diabetic retinopathy. 5. Current use of medications that may affect visual function or electroencephalographic activity. 6. Occurrence of uncorrectable artifacts during SSVEP recording. 7. Pregnancy or lactation. 8. Any other condition considered by the investigators to render the participant unsuitable for enrollment.

测量方法:

采用频率、相位、空间位置联合调制的刺激编码方法。每个时间只呈现一个(或少数)视野区域的刺激,单眼记录,采用无创脑电信号采集技术,重点记录大脑视觉(枕叶)皮层的脑电信号,确保记录电极能够覆盖整个视觉皮层;在此基础上,考虑同时记录其他脑区的脑电数据。

Measure time point of outcome:

Measure method:

A stimulus encoding paradigm based on joint modulation of frequency, phase, and spatial location will be adopted. At each time point, stimulation will be presented to only one (or a limited number of) visual field region(s). Recordings will be obtained monocularly using a noninvasive electroencephalography (EEG) acquisition system. EEG signals will be primarily recorded from the visual cortex in the occipital lobe, and the electrode montage will be arranged to ensure adequate coverage of the ent
