Glaucoma is an eye disease that if untreated can damage the optic nerve, impair vision and cause blindness. It is particularly sight threatening in that in its most common form it doesn’t strike the patient with any warnings or symptoms. Thus, becoming familiar with glaucoma risk factors is worthwhile for all patients.  While we have known for quite some time about the increased risk among family members and certain ethnic and racial backgrounds, those patients of Latino or African, ancestry are clearly at greater risk for high pressure within the eye and thus should be aware of the need for routine eye exams and glaucoma testing at the direction of their eye doctor. Researchers from the UIC College of Medicine analyzed data from 3,541 participants 40 and older from the Mexican American Glaucoma Genetic Study, part of the Los Angeles Latino Eye Study and found that as the percent of African ancestry went up, intraocular pressure rose.

According to a report in the journal Ophthalmology, African ancestry carried more risk for high intraocular pressure than high body mass index, older age and high blood pressure-factors known to contribute to increased pressure inside the eye. The key to preventing vision loss from glaucoma is early detection, diagnosis and treatment.

If you or some you know has known glaucoma risk factors including diabetes, high blood pressure, is a smoker, has a family history of glaucoma, obesity or suffers from sleep apnea and you are of Latino or African ancestry, it is quite important that you have regular eye exams and glaucoma testing.

The excellent advances in glaucoma diagnosis and treatment still require patients to play an active role in their care by scheduling regular eye exams with the appropriate level of glaucoma testing based on their examination, risk factors and doctor’s recommendations. Glaucoma risk factors that may make additional testing or more frequent exams necessary include diabetes, high blood pressure, vascular disease, an early onset of menopause, sleep apnea, any family history of glaucoma-especially among siblings, excessive alcohol use and smoking, as well as race since if you are of African-American or Hispanic descent, you have greater risk of glaucoma.

Glaucoma Eye Exams–Eye exams for glaucoma should begin by checking your visual acuity with and without your eyeglasses or contact lenses. Then, the tonometry test should be performed. This is a method of measuring your Intraocular Pressure (IOP) and gives us the first piece of important information in determining whether you might have glaucoma. Ophthalmoscopy and high magnification contact lens exams are examination procedures used to detect and diagnose glaucoma by carefully examining the inside of the eye-especially the optic nerve-in order to detect glaucoma.  It is necessary to have some eye drops placed in your eyes in order to dilate your pupils so that the doctors can make a clear and direct observation of the optic nerve.

Glaucoma Testing–If either the Intraocular Pressure (IOP) is elevated or the optic nerve appears unusual, additional tests will be necessary in order to complete the glaucoma examination. These may include Visual Field Perimetry, Gonioscopy, Optic Nerve Computer Imaging and Pachymetry. Should you need any of these tests we explain them fully to you and answer your questions so that you understand how they allow us to diagnose glaucoma.

If you are under 40 years of age and do not have any meaningful risk factors, then having a glaucoma eye examination every two years should be sufficient. If you have any glaucoma risk factors, then an annual exam or as frequently as directed by your eye doctor is necessary to maintain eye health and vision.
