Article: In focus 2004;82:887-8.

The author of this feature (1) fails to mention the most common cause of glaucoma worldwide, chronic primary angle closure (CPAC) glaucoma. She describes angle closure as having symptoms of "headaches, blurred vision and pain in the eye". In contrast to the ACUTE angle closure described in the article, CACG glaucoma, much like primary open angle glaucoma, has no symptoms until there is advanced field loss; accordingly, patients present late in the course of the condition. The author also states that "few reliable data from these countries ("China and other parts of Asia"). In fact, there are numerous very well done papers, including one by Paul Foster from Moorfields and the Centre for Community Eye Health describing CPAC in Mongolia and numerous papers from The Singapore Eye Centre.
