纳入标准: |
正常眼压性青光眼 (NTG) 的诊断标准: (1) 连续六次未经治疗的眼压 (IOP) 中位数读数均低于 21 mmHg,且不超过一次读数等于 23 或 24 mmHg,单次测量值均不超过 24 mmHg。至少两次读数是在一天中与其他读数不同的时间获得的; (2) 暗室房角镜检查显示 Shaffer 分级 II 级或以上; (3) 青光眼性视盘凹陷和神经视网膜缘缺失; (4) 符合青光眼性视野缺损的最低标准(见下文); (5) 根据 Hodapp-Parrish-Anderson 青光眼分级标准21,视野缺损程度为“中度”或“重度”,即 Humphrey 自动视野计平均偏差 (MD) 为 -6.00 至 -20.00 dB。 (6)“正常眼压性青光眼(NTG)及其进展的解剖血管危险因素识别”研究的参与者,包括正常眼压性青光眼(NTG)患者和正常对照组参与者。 原发性开角型青光眼(POAG)的诊断标准: (1)记录到的最高眼压(IOPmax)≥30mmHg,无论是否使用降眼压药物,但不包括与急性原发性闭角型青光眼发作相关的眼压升高; (2)房角镜检查显示任何Shaffer分级的房角; (3)青光眼性视盘凹陷和神经视网膜缘缺失; (4)符合青光眼性视野缺损的最低标准(见下文)。 (5)根据 Hodapp-Parrish-Anderson 青光眼分级标准(表 2),患有“中度”和“重度”视野缺损的青光眼眼,即 Humphrey 自动视野计的平均偏差 (MD) 为 -6.00 至 -20.00 dB。 对照组:我们从香港眼科医院门诊招募年龄匹配的健康对照组受试者。他们的前房角为Shaffer II级或以上,未经治疗的眼压低于21 mmHg,无青光眼或其他眼部疾病的家族史或个人史(除视力影响不大的老年性白内障或小于3D的近视/远视外),且无可能增加青光眼风险的全身性疾病,例如葡萄膜炎、需要使用类固醇的疾病、眼压升高和/或视神经乳头形态异常。 |

Inclusion criteria |
Diagnostic criteria of NTG: (1) Six median untreated intraocular pressure (IOP) readings consistently less than 21 mmHg, with no more than 1 reading equal to 23 or 24 mmHg and no single measurement more than 24 mmHg. At least 2 readings were obtained at a different time of the day from the rest; (2) Drainage angle of Shaffer grade II or above on dark room gonioscopy; (3) Glaucomatous optic disc cupping and loss of neuroretinal rim; (4) Fulfils the minimal criteria for glaucomatous visual field defect (see below); (5) Glaucoma eyes with ‘Moderate’ and ‘Advanced’ visual field defects according to the Glaucoma grading scale of Hodapp-Parrish-Anderson 21 i.e. mean deviation (MD) in Humphrey automated perimetry of -6.00 to -20.00 dB; (6) Participants of "Identification of anatomical vascular risk factors for normal tension glaucoma (NTG) and NTG progression" study as normal tension glaucoma (NTG) participants or normal control participants. Diagnostic criteria of POAG: (1) Documented maximum IOP (IOPmax) of >=30mmHg with or without IOP-lowering medication, but excluding elevated IOP associated with episodes of acute primary angle closure attack; (2) Drainage angle of any Shaffer grading on gonioscopy; (3) Glaucomatous optic disc cupping and loss of neuroretinal rim; (4) Fulfils the minimal criteria for glaucomatous visual field defect (see below); (5) Glaucoma eyes with ‘Moderate’ and ‘Advanced’ visual field defects according to the Glaucoma grading scale of Hodapp-Parrish-Anderson (Table 2), i.e. mean deviation (MD) in Humphrey automated perimetry of -6.00 to -20.00 dB. Control subjects: Age-matched healthy controls are recruited from our clinic at Hong Kong Eye Hospital. They have an anterior chamber angle of Shaffer grade II or above, untreated IOP of below 21 mmHg, and no family or personal history of glaucoma or other ocular diseases (except visually insignificant senile cataract or myopia / hyperopia of less than 3D), and no systemic diseases that may increase the risk of developing glaucoma, such as uveitis, diseases requiring the use of steroid, having ocular hypertension and / or suspicious optic nerve head morphology. |

排除标准: |
(1)继发性眼压升高或青光眼性视神经病变(例如,既往眼外伤、使用类固醇、葡萄膜炎等); (2)患有疾病而无法准确测量眼压、视力、进行OCT/OCT-A成像和视野检查的患者; (3)既往接受过眼科手术的患者(单纯性白内障手术除外); (4)患有全身性血管疾病的患者,因为缺血性病变是原发性开角型青光眼(POAG)和正常眼压性青光眼(NTG)的重要危险因素; (5)近6个月内服用过全身性抗生素的患者; (6)无法提供知情同意的患者。患有糖尿病或无法提供知情同意的患者将不会被邀请参加这项研究。 |
||||||||||||||||||||||
|
Exclusion criteria: |
(1) Secondary causes for ocular hypertension or glaucomatous optic neuropathy (e.g., previous ocular trauma, steroids use, uveitis, etc.); (2) Patients with diseases precluding accurate measurement of IOP, visual acuity, OCT / OCT-A imaging, and performance of VF tests; (3) Patients who had previous ocular surgery (except uncomplicated cataract surgery); (4) Patients with systemic vascular disorders as ischemic disturbance is a significant risk factor to POAG and NTG; (5) Patients who have taken systemic antibiotics in the last 6 months; (6) Unable to give informed consent. Patients with diabetes mellitus, or who are unable to provide informed consent, will not be invited to participate in this study. |
