Angle-closure glaucoma

Other Names:

Primary angle-closure glaucoma
Secondary angle-closure glaucoma
Narrow-angle glaucoma
Closed-angle glaucoma

Nature:

Angle-closure glaucoma, also known as narrow-angle glaucoma, is caused by blocked drainage canals in the eye, resulting in a sudden rise of pressure in the eye. This is a much more rare form of glaucoma, which develops very quickly and demands immediate attention.

Incidence:

People who have farsightedness are at an increased risk for acute angle-closure glaucoma because their eyes are smaller, their anterior chambers are shallower, and their angles are narrower.

In the United States, fewer than 10% of glaucoma cases are due to angle-closure glaucoma. In Asia, angle-closure glaucoma is more common than open-angle glaucoma.

Certain races, i.e. Asians and Eskimos, have narrow angles and are more likely to develop angle-closure glaucoma than Caucasians. Angle-closure glaucoma among American Indians is lower than among Caucasians. In Caucasians, angle-closure glaucoma is three times higher in women than in men. In African Americans, men and women are affected equally.

About the Encyclopedia

The Encyclopedia of World Problems and Human Potential is a unique, experimental research work of the Union of International Associations. It is currently published as a searchable online platform with profiles of world problems, action strategies, and human values that are interlinked in novel and innovative ways. These connections are based on a range of relationships such as broader and narrower scope, aggravation, relatedness and more. By concentrating on these links and relationships, the Encyclopedia is uniquely positioned to bring focus to the complex and expansive sphere of global issues and their interconnected nature.

The initial content for the Encyclopedia was seeded from UIA’s Yearbook of International Organizations. UIA’s decades of collected data on the enormous variety of association life provided a broad initial perspective on the myriad problems of humanity. Recognizing that international associations are generally confronting world problems and developing action strategies based on particular values, the initial content was based on the descriptions, aims, titles and profiles of international associations.

About UIA

The Union of International Associations (UIA) is a research institute and documentation centre, based in Brussels. It was established in 1907, by Henri la Fontaine (Nobel Peace Prize laureate of 1913), and Paul Otlet, a founding father of what is now called information science.

Non-profit, apolitical, independent, and non-governmental in nature, the UIA has been a pioneer in the research, monitoring and provision of information on international organizations, international associations and their global challenges since 1907.
