Early detection, treatment are critical to slowing progression of the disease By Meghann Finn Sepulveda

ffecting more than 3 million people in the United States, glaucoma is a disease that damages the eye’s optic nerve as a result of increased pressure from fluid buildup. According to the American Academy of Ophthalmology, glaucoma is considered the leading cause of blindness in people over age 60.

Risk factors Age is considered one of the major risk factors in the development of glaucoma. Risk increases at age 40 but is much more prevalent in the more senior population. By the time a person reaches age 80, the risk of glaucoma can be as high as 10 percent. Family history is also a risk factor, while people of African-American, Hispanic and Northern European ancestry are more susceptible to developing certain types of glaucoma. People who use steroid medication and those who have had eye surgery are also at higher risk. “Anyone who has experienced trauma to the eye, or those who suffer from systemic and inflammatory diseases such as diabetes, are at increased risk,” said John Lewis, M.D., an ophthalmologist at Southwestern Eye Center. Those identified as high risk should speak to an eye doctor for an evaluation to identify any deficiencies.

osalie Leman, R.N., C.D.E., is a registered nurse and certified diabetic educator at Banner Baywood Medical Center in Mesa. She said that when she started in her field 18 years ago, patients would often say ‘I’m borderline diabetic but I’m not worried’. “Now, doctors are a lot more aggressive about treating someone with pre-diabetes,” she said. Pre-diabetes almost always precedes a diagnosis of diabetes, said both Leman and Karla Birkholz, M.D.,

Early detection Glaucoma begins to occur when fluid can’t drain properly from the eye. The fluid buildup causes a blockage and increases eye pressure to the optic nerve. Typically, people with primary openangle glaucoma — the most common form of glaucoma — have no symptoms in the early stages of the disease. Eye pressure levels should be monitored but because levels can fluctuate throughout the day, experts say that checking eye pressure alone is not the most effective way to screen for glaucoma. “There are more than 50 types of glaucoma,” Lewis said. “In addition to testing eye pressure, a full examination should be performed inside the eye to look at the optic nerve and see if there are any signs of structural damage.” Along with elevated eye pressure, one of the early signs of glaucoma is gradual changes to peripheral vision.

Insulin resistance Before someone develops pre-diabetes, he or she likely has a problem called insulin resistance, a dysfunction in the way the body uses insulin, Birkholz explained. The main causes of insulin resistance aren’t surprising: genetics, being overweight and not exercising enough. Exercise is critical, both Birkholz and Leman said. “Just sitting for a period of time and not using your muscles can raise your risk of insulin resistance,” Birkholz said, adding that while any amount of exercise helps, the goals are to get to 30 minutes of exercise at least five days a week and to move at least a few minutes every hour. To monitor possible insulin resistance, some physicians may order a ‘lipid particle’ test. ‘Bad’ (LDL) cholesterol particles become smaller and denser with excess sugar in your system, Birkholz said. “If you have a large number of these more dangerous small, dense LDL particles, there’s a higher likelihood you may have insulin resistance,” she said. Increasing evidence shows that too much sugar causes cholesterol and inflammation problems that lead to heart disease, she said. If you have insulin resistance, Birkholz recommends taking the same steps encouraged to treat pre-diabetes — getting more exercise, losing at least 5 percent of your body weight, consuming less sugar and fewer processed foods, and eating more foods in their natural, original state.
Karla Birkholz, M.D., a family physician and the wellness medical director for HonorHealth, says exercise is key in helping to prevent or at least delay the onset of diabetes. She recommends 30 minutes of exercise five days a week and to move at least a few minutes every hour. “Just sitting for a period of time and not using your muscles can raise your risk of insulin resistance,” she said.
