Summary
Glaucoma blindness risk is high in developing countries, where most are unaware. In developed nations, advanced visual field loss and noncompliance increase blindness risk from open-angle glaucoma.
Area of Science:
- Ophthalmology
- Public Health
- Global Health
Background:
- Glaucoma is a leading cause of irreversible blindness worldwide.
- Understanding risk factors for glaucoma-induced blindness is crucial for prevention and treatment strategies.
- Disparities in glaucoma care exist between developed and developing countries.
Purpose of the Study:
- To review current estimates of blindness from glaucoma.
- To identify key risk factors associated with glaucoma-induced blindness.
- To highlight challenges in preventing glaucoma blindness, particularly in developing nations.
Main Methods:
- Review of long-term retrospective studies on open-angle glaucoma in developed countries.
- Analysis of population-based studies on glaucoma in developing countries.
- Synthesis of data on risk factors for blindness progression and presentation.
Main Results:
- Progression to bilateral blindness is uncommon in treated open-angle glaucoma patients in developed countries.
- Advanced visual field loss at presentation and noncompliance are significant risk factors for blindness in developed countries.
- Developing countries face high rates of glaucoma-induced blindness, often due to lack of awareness and treatment obstacles.
Conclusions:
- The greatest risk factor for glaucoma blindness globally is residing in a developing country.
- Targeted screening, public education, and improved treatments are essential to reduce global glaucoma blindness.
- Addressing socioeconomic factors and healthcare access is critical for effective glaucoma blindness prevention worldwide.
