纳入标准:

Inclusion criteria

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.
