How this condition is diagnosed and what test results mean.
Initial screening tests
Standard diagnostic workup

Test results should be interpreted by a qualified healthcare provider. [Content pending medical review.]
Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Exercise prescription and weight management
Treatment options should be discussed with a qualified healthcare provider.
Intraocular pressure-lowering drops
Topical eye medications including prostaglandin analogs, beta-blockers, or carbonic anhydrase inhibitors that reduce fluid production or increase drainage. Multiple medications may be combined to achieve target pressure levels.
Regular tonometry and visual field testing
Frequent measurement of intraocular pressure combined with visual field examinations to detect disease progression. This monitoring approach helps guide treatment adjustments and prevents irreversible vision loss.
Additional treatment options
Laser trabeculoplasty
Laser procedure to improve aqueous humor drainage through the trabecular meshwork, reducing intraocular pressure. Less invasive than traditional surgery with quicker recovery time.
surgicalHead position and activity modifications
Avoiding activities that increase intraocular pressure such as inverted yoga positions, heavy weightlifting, or prolonged head-down postures. Regular exercise and eye protection from trauma support overall eye health.
lifestyleNutritional supplementation
Dietary intake of omega-3 fatty acids, antioxidants, and vitamins A, C, E may support retinal and optic nerve health. While not replacing medical treatment, these supplements complement standard care.
