How is normal tension glaucoma treated?

Lower eye pressure: Normal tension glaucoma exists when the pressure in the eye, despite being what we call normal, causes changes that mimic ordinary glaucoma damage. Treatment is with drops and surgery to get the pressure even lower. The goal is the same, to get the pressure lower to a level that allows the eye to function but causes no pressure damage. It is not very common.

Lowering IOP: Whether low tension glaucoma or higher tension glaucoma, the goal is to preserve vision, and lowering the iop about 25 to 30% of where the average iop has been is key. Iop reducing strategies involve any of the following: medications, laser trabeculopasty, and incisional surgery. More experimental ( or case by case) use of systemic medications such as calcium channel blockers or gingko, r possible.
