Primary Open Angle Glaucoma Epidemiology Forecast Report Coverage

Expert Market Research's “Primary Open Angle Glaucoma Epidemiology Forecast Report 2026-2035” offers comprehensive information on the prevalence and demographics of primary open angle glaucoma. It projects the future incidence and prevalence rates of primary open angle glaucoma cases across various populations. The study covers age, gender, and type as major determinants of the primary open angle glaucoma population. The report highlights patterns in the prevalence of primary open angle glaucoma over time and projects future trends based on multiple variables.

Primary Open Angle Glaucoma Understanding: Disease Overview

POAG is a chronic, progressive optic neuropathy characterized by gradual vision loss due to optic nerve damage. It is the most common form of glaucoma worldwide and often remains asymptomatic in early stages, leading to delayed diagnosis. Elevated intraocular pressure is a major risk factor, though normal-tension cases also occur. The disease is associated with impaired aqueous humor drainage through the trabecular meshwork. Risk increases with age, family history, diabetes, and myopia. Without timely management, irreversible visual field loss and blindness may develop gradually over time in untreated cases globally.

Primary Open Angle Glaucoma Epidemiology Perspective

The primary open angle glaucoma epidemiology division offers information on the patient pool from history to the present as well as the projected trend for each of the 8 major markets. Expert Market Research provides both current and predicted trends for the primary open angle glaucoma epidemiology scenario by examining a wide range of studies. Additionally, the report covers the diagnosed patient pool for primary open angle glaucoma and their trends. The data is broken down into specific categories, such as total prevalent cases in males and females, and total diagnosed cases across different age groups and patient pools.

• According to Sujan Banik et al., 2025, the pooled prevalence of primary open angle glaucoma (POAG) in South Asia was 1.6% (95% confidence interval 1.2–2.1), within an overall glaucoma prevalence of 2.1%, confirming POAG as the most dominant subtype regionally.
• According to Kelsey V. Stuart et al., 2025, age-wise prevalence increased sharply from 0.22% in individuals aged 40–44 years to 10.74% in those aged 85 years and above, demonstrating a strong correlation between advancing age and higher POAG burden, reflecting progressive optic nerve damage over time.
• According to Sujan Banik et al., 2025, gender differences showed POAG prevalence was higher in males (2.26%) than females (1.61%), with overall open-angle glaucoma prevalence also slightly higher in men (2.2%) compared to women (2.0%), indicating consistent male predominance.
• According to Joshua R. Ehrlich et al., 2024, glaucoma affected approximately 4.22 million individuals in the United States in 2022, with prevalence of 1.62% among adults aged 18 years or older and 2.56% among those aged 40 years or older.
• According to Joshua R. Ehrlich et al., 2024, around 1.49 million individuals had vision-affecting glaucoma, with prevalence of 0.57% in adults aged 18 years or older and 0.91% in those aged 40 years or older, highlighting significant burden of visual field loss and long-term disability.

Country-wise Primary Open Angle Glaucoma Epidemiology

The primary open angle glaucoma epidemiology data and findings for the United States, Germany, Spain, Italy, France, the United Kingdom, Japan, and India are also provided in the epidemiology section.

Across the regions, the epidemiology reflects a substantial and growing public health burden. According to Jonathan S. Myers et al., 2025, glaucoma accounts for 9-12% of blindness in the United States, with prevalence among Medicare Fee-for-Service enrollees increasing from 12.7% in 2014 to 13.6% in 2019, and nearly 80% of cases being open-angle glaucoma. As per Sujan Banik et al., 2025, the global prevalence of POAG is approximately 3.1% among individuals aged 40 years and older, including populations across the United Kingdom, Germany, France, Spain, Italy, Japan, and India, consistent regional disease burden driven by rising intraocular pressure and aging populations.

Primary Open Angle Glaucoma: Treatment Overview

Treatment of POAG focuses on lowering intraocular pressure to slow disease progression and preserve vision. First-line glaucoma treatment includes pharmacologic therapy, primarily eye drops such as prostaglandin analogs, beta blockers, alpha agonists, and carbonic anhydrase inhibitors. These agents improve aqueous outflow or reduce production. Laser trabeculoplasty may be used when medications are insufficient. In advanced cases, surgical interventions like trabeculectomy or minimally invasive glaucoma surgery are recommended. Lifelong monitoring is essential to adjust therapy and prevent optic nerve deterioration and visual field loss, and maintain long term visual function outcomes effectively managed.
