January is Glaucoma Awareness Month and the University of Southern California (USC) Eye Institute is offering insight into the effects of glaucoma and today’s cutting-edge treatments.

According to a study by researchers at the USC Eye Institute published in 2012 more than 2.7 million people older than 40 living in the United States suffer from glaucoma, and that number will only continue to increase. The single largest demographic group is non-Hispanic white women. Those who lose vision from glaucoma cannot recover the sight they have lost. However, glaucoma is the leading cause of preventable blindness. That is why the USC Eye Institute and institutions from around the world are taking the month of January to recognize Glaucoma Awareness Month.

As a leader in ophthalmology, the ophthalmologists at the USC Eye Institute are dedicated to bringing the causes and effects of glaucoma to the forefront of public consciousness. Led by Rohit Varma, MD, MPH, Professor and Chair of the Department of Ophthalmology, Director of the USC Eye Institute, and a leading expert in the field of glaucoma, USC is continuing to make improve glaucoma care. Dr. Varma has brought awareness and improved treatments to the field of glaucoma for years, with his work leading to life-changing treatments that have been spotlighted in the media, including The Doctors.

ADVANCING GLAUCOMA CARE
There are two main types of glaucoma: primary open-angle glaucoma (POAG) and angle-closure glaucoma, both of which damage the optic nerve, leading to vision loss. Glaucoma-caused vision loss begins with the loss of peripheral vision. Most people suffering from glaucoma do not notice it until it has taken away a significant portion of their sight. Through regular eye exams, an eye doctor can detect glaucoma early and treat it. Early detection and treatment of glaucoma can prevent permanent vision loss and blindness. Additionally, while many doctors use the puff test to check for high eye pressure, this is a very poor test for detection of glaucoma. Dr. Varma recommends that direct examination of the optic nerve and testing the peripheral vision are the best tests for the early detection of glaucoma. Furthermore, he cautions that damage to the optic nerve can occur at seemingly "normal" eye pressure, therefore it is very important to examine the optic nerve for early damage.

Once glaucoma damage has been detected, then the single most effective way to treat it is the lower the eye pressure even if it may be in the "normal" range. This is usually done using eye drops or even a laser. However if both eye drops and laser are unable to lower the eye pressure, then surgery can be performed.

“We are currently working on novel intraocular drainage devices, intraocular pressure sensors as well as drug delivery systems that will improve quality of life as well as compliance of our patients,” said Dr. Alena Reznik, Assistant Professor of Ophthalmology at the USC Eye Institute. “The USC Eye Institute offers minimally invasive surgical techniques, such as iStent and endocyclophotocagulation, as well as conventional surgery such as trabeculectomy with anti-scarring agents and glaucoma drainage devices. In complicated cases, we are able to offer a multi speciality combined surgical approach that includes corneal and retinal intervention together with glaucoma surgery, decreasing recovery time for patients.”

At the USC Eye Institute, leading ophthalmologists have helped to create some of most advanced treatments for glaucoma ever made. These include a non-invasive imaging technique that can diagnose glaucoma early and the Baerveldt glaucoma implant, which is now the world’s most widely-used implant for glaucoma.

In addition, Dr. Varma and his team of researchers at the USC Ocular Epidemiology Center have conducted several groundbreaking community health-based studies, assessing the prevalence of glaucoma diseases amongst our diverse population. The US Centers for Medicare began providing a Glaucoma Screening benefit to Latinos aged 50 years and older based on data from the Los Angeles Latino Eye Study (LALES), showing the high rate of glaucoma in the study. There have been a multitude of studies that have helped provide similar eye disease data.

If you have any reason to believe that you may have or may be at risk, please do get your eyes examined with an emphasis on assessing the optic nerve and peripheral vision. Persons who either have a family member with glaucoma, or if you are 50 years and older, should get a complete eye examination.
