essential as loss is irreversible
Glaucoma damage is irreversible and progressive.
Treating glaucoma is liking sailing a ship. Things move slowly but inexorable. The only way to steer the ship from sailing into the rocks ( blindness) is to lower the intra-ocular pressure to achieve a target pressure with various combinations of medications, laser or surgery.
How is glaucoma detected?
Regular eye examinations by your ophthalmologist are the best way to detect glaucoma. A glaucoma screening that checks only the pressure of the eye is not sufficient to determine if you have glaucoma.
