Low-tension glaucoma is associated with the following:

  • Migraine

  • Peripheral vasospasm, Raynaud syndrome

  • Generalized peripheral vascular endothelial dysfunction [7]

  • Ocular circulation insufficiency (lower ocular pulse amplitude) [7]

  • Increased resistance index in the central retinal artery (role in progression of visual field defect) [8]

  • Impaired vascular autoregulation (prolonged arteriovenous venous passage time in relation to ocular perfusion) [9]

  • Autoimmune disorders

  • Systemic vascular disease (ie, atherosclerotic disease, cerebrovascular insufficiency) [10]

  • Systemic nocturnal hypotension

  • Sleep apnea (decreases oxygen saturation)
