Glaucoma
Glaucoma is an eye condition where the pressure within the eye is elevated to the point of causing damage to vision. Patients with Glaucoma are typically put on eye drops that reduce the pressure to a safe range. The majority of patients do quite well on medication. Others may require surgery to control the pressure. New studies suggest that exercise may help prevent the need for surgery.
Exercise
A study by the Oregon Health Sciences University showed that 3 months of aerobic exercise reduced the intraocular pressure by almost 5 points. This amount of reduction could mean the difference between medical control and having to resort to surgery. They also found that by 3 weeks after cessation of the exercise the pressure had returned to pre-exercise levels. Another study in Pakistan showed that immediately after exercise, the amount of pressure was directly related to the intensity of aerobic exercise.
Recommendation
So, if you (or someone you know) is having trouble with their glaucoma control, you might be best advised to get on the treadmill or exercise bike and get exercising. We don’t want you to lose any more sight.
