Dr. David D. Kim has worked in ophthalmology for more than 20 years. Currently based in Tucson, Arizona, he treats patients at Arizona Eye Consultants. Previously a clinical associate professor at the Medical College of Wisconsin, Dr. David D. Kim maintains membership in the American Glaucoma Society and the American Academy of Ophthalmology (AAO).
On its website, the AAO offers a number of print and video resources for laypeople, including basic information on glaucoma. In its videos, the organization provides a simple explanation of the disease, and emphasizes the importance of regular eye exams as the best means of preventing or stopping its progress.
Glaucoma typically results due to an increase in pressure inside the eye, usually caused by excess fluid build-up. The healthy eye constantly manufactures its own lubricating fluid (called the aqueous humor), which drains out of a tiny area called the trabecular meshwork. Any blockage of proper drainage can elevate intraocular pressure to dangerous levels. Pressure can damage the optic nerve, leading to irreversible loss of visual field or total blindness.
Because glaucoma typically develops without obvious warning symptoms, it is imperative for all adults (and particularly older adults) to see their ophthalmologists for regular check-ups. When diagnosed early, glaucoma can be successfully treated with medication or surgery.
