Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Alpha-2 Adrenergic Agonists
Topical alpha-2 agonists like brimonidine reduce aqueous humor production while increasing uveoscleral outflow. They provide neuroprotective benefits beyond IOP reduction.
Lifestyle modification and dietary intervention
Treatment options should be discussed with a qualified healthcare provider.
Additional treatment options
Laser Peripheral Iridotomy
Creating a small hole in the peripheral iris can improve aqueous flow dynamics, though this procedure is more commonly associated with angle-closure variants and may be adjunctive in certain open-angle presentations.
procedureTube Shunt Implantation
Glaucoma drainage devices like Ahmed or Baerveldt tubes create an alternative drainage pathway for aqueous humor. Reserved for cases refractory to conventional surgery.
surgicalNutritional Supplementation Discussion
While evidence is limited, discussing nutritional approaches including omega-3 fatty acids and antioxidants may provide adjunctive support. Patients should understand these complement rather than replace standard therapy.
complementary24-Hour Intraocular Pressure Monitoring
Extended IOP monitoring through diurnal curve testing or continuous monitoring devices identifies pressure fluctuations that single clinic measurements may miss, particularly relevant for type B variants.
