Glaucoma, one of the leading causes of blindness, is estimated to affect 1 of every 50 adults. Although glaucoma can occur at any age, the risk of developing the disease increases dramatically after the age of 35. Glaucoma is also more likely to develop in persons who are severely nearsighted, persons with a family history of the condition, diabetics and blacks. Because the symptoms of early glaucoma are so slight, the disease often goes unnoticed until permanent vision loss has occurred. However, with early diagnosis and careful treatment, visual damage from glaucoma can be prevented.
