What is the primary aim of glaucoma treatment?

The primary aim of glaucoma treatment is to lower intraocular pressure. Glaucoma is characterized by increased pressure in the eye that can lead to damage of the optic nerve and subsequent vision loss. By reducing intraocular pressure, the treatment helps to prevent further damage and preserve remaining vision. The focus is not on restoring vision that has already been lost, as this is typically not possible, nor does it involve correcting refractive errors, which are associated with vision clarity rather than intraocular pressure. Providing symptomatic relief is not the goal since glaucoma may have few or no symptoms until significant damage has occurred; thus, managing pressure is the most critical aspect of treatment.
