There are several risk factors for glaucoma. Age is one of the main risk factors, i.e. the condition is more likely to affect you the older you are. Other risk factors include family history (The Baltimore Eye Survey found that open-angle glaucoma is increased approximately 3.7 times for those with a sibling with this most common form of glaucoma), and also race, high eye pressure, diabetes, eye injury, and steroid use.
