Glaucoma

Overview

Glaucoma occurs when there is damage to the optic nerve, often due to pressure inside the eye. This pressure builds when the eye’s aqueous fluid cannot drain properly. Damage from the pressure causes loss of peripheral vision, and, eventually, blindness.

Each year, our volunteer surgeons provide sight-restoring surgeries to hundreds of men, women, and children who are blind with glaucoma. Give sight now to support our programs that help those with this disease see again.

Prevalence

The International Agency for the Prevention of Blindness reports that glaucoma is the third leading cause of blindness globally. It is expected that 76 million people will have the condition by 2020. Of those affected, 11 million will be blind in both eyes.

Between 2013 and 2040, the number of people with the disease is expected to increase by 74 percent. This is primarily due to the aging of the global population, and increased life expectancy in Asia and Africa, regions disproportionately affected by the disease.

Risk Factors

Glaucoma often runs in families, and frequently occurs in individuals over 60. In addition, it disproportionately affects people of Asian and African descent, accounting for 60 and 13 percent of all glaucoma cases, respectively.

Men are more likely than women to have primary open-angle glaucoma, the most common form of the disease in the U.S.

Prevention

Ophthalmologists recommend the following strategies to reduce the risk of developing glaucoma:

  1. Exercise frequently and maintain a well-balanced diet
  2. Schedule regular eye exams in order to detect the condition before vision loss occurs
  3. Follow your doctor’s instructions regarding regular use of eye drops to prevent intraocular pressure build-up

Treatment

Glaucoma is especially challenging to treat in regions without access to regular eye care services. Traditionally, eye doctors prescribe medicated eye drops to lower intraocular pressure and prevent further vision loss. However, patients in underserved communities rarely have access to high-quality medicated drops, due to the expense and poor compliance.

Optic nerve damage is irreversible, so effective treatment methods strive to prevent blindness, peripheral and bilateral, before it occurs. SEE International partners with the Glaukos Corporation to treat the disease and train doctors across the globe in the iStent microsurgical technique. During this minimally invasive procedure, ophthalmologists use a local anesthetic to insert a shunt, called the iStent Trabecular MicroBypass. This device facilitates aqueous fluid outflow to reduce intraocular pressure without the need for eye drops. More information on Glaukos and the iStent Trabecular MicroBypass device can be found here.

SEE International & Glaucoma Around the World

SEE works to prevent glaucoma around the world by:

  • Screening patients and their families
  • Performing microinvasive surgery on those suffering from it
  • Training local eye care personnel in appropriate screening and surgical techniques
