Objectives

Narrative objectives1

1, Cross sectional study
To determine whether autonomic dysfunction characterized by reduced heart rate variability(HRV) and sympathetic predominance is associated with decreased optic nerve head blood flow (measured by LSFG), thinning of the nerve fiber, and visual field defect in glaucoma patients with sleep apnea syndrome (SAS).

2, Longitudinal study
Among glaucoma patients with SAS who initiate CPAP therapy, we will evaluate changes in autonomic indicators, ocular blood flow, and visual function from baseline to 15 months. We will also compare outcomes between patients with good versus poor CPAP adherence to clarify the long term effects of CPAP treatment.

Assessment

Primary outcomes

1, Changes in HRV parameters
2, Changes in LSFG measurements.
3, Progression slopes of visual field MD and visual field sensitivity.
4, Comparison of the above changes between patients with good CPAP adherence (more than 4 h/night, more than 80%) and those with poor adherence.
