There are several known risk factors for glaucoma. Some of these include elevated intraocular pressure, age, race, corneal thickness, and family history. Diabetes and refractive error have also been shown to be risks factors in some studies. Thus, higher eye pressure is a risk factor for the development of glaucoma but does not necessarily mean you have glaucoma. There are some patients who have higher eye pressures and never develop glaucoma and alternatively there are patients with normal eye pressure that can develop a type of glaucoma called “normal tension” or “low tension” glaucoma. Regular screening eye exams are essential for diagnosis. It is particularly important if you have ever had documented high eye pressures or have a family history of glaucoma to be followed regularly by an eye physician to prevent the subtle and permanent vision loss that can occur with glaucoma.
