Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Age-Appropriate Pressure-Lowering Drops
Eye drops formulated to reduce intraocular pressure remain a cornerstone of treatment for primary open-angle glaucoma across age groups. Pediatric formulations may differ for younger patients, and compliance support is particularly important for children and young adults.
Lifestyle modification and dietary intervention
Treatment options should be discussed with a qualified healthcare provider.
Laser Trabeculoplasty
Laser procedures to enhance outflow through the trabecular meshwork can be effective in congenital, juvenile, and adult-onset forms. SLT is increasingly used as an alternative or adjunct to medications, particularly when compliance is challenging.
Additional treatment options
Comprehensive Glaucoma Surveillance
Regular examinations including pressure checks, optic nerve imaging, and visual field testing are essential for all age groups. More frequent monitoring is typically needed for congenital and juvenile cases due to higher progression risk.
monitoringAntioxidant-Rich Nutritional Support
A diet rich in leafy green vegetables, omega-3 fatty acids, and antioxidants may support overall eye health. Some studies suggest dietary nitrate from vegetables may have a protective effect on optic nerve health.
dietaryMinimally Invasive Glaucoma Surgery (MIGS)
Newer surgical options that offer lower risk profiles than traditional filtering surgery. These procedures can be combined with cataract surgery or performed as standalone procedures and are suitable for various age groups.
