2

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.

3

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.

Head 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.

lifestyle

Nutritional 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.
