    Glaucoma medication is divided into groups based on chemical structure and pharmacologic action. The goal of currently available glaucoma therapy is to preserve visual function by lowering intraocular pressure (IOP), below a level that is likely to produce further damage to the nerve.

    The more advanced the glaucomatous process on initial presentation, the lower the target range generally needs to be to prevent further progression. This more aggressive target is meant to minimize the risk of progressive glaucoma damage and vision loss. Once the optic nerve is damaged, it is more likely to incur more damage, and if severe visual loss is present, there is greater impact on the patient from any additional damage that may occur.

    An initial reduction in the intraocular pressure of 20% from baseline is suggested. However, reduction of IOP to the target pressure range does not guarantee that progression will not occur. Therefore, the target pressure range needs to be constantly reassessed and changed as dictated by IOP fluctuations, optic nerve changes, and/or visual field progression.

    Medical uses

    Agents in common clinical use include:

    When comparing people with primary open-angle glaucoma and ocular hypertension, medical intraocular pressure lowering treatment slowed down the progression of visual field loss.
