The Different Classifications of Glaucoma

by Jamie Peters

Glaucoma is a sight-threatening eye disease that generally develops due to an increase in intraocular pressure (IOP), which can lead to compression of your optic nerve. The condition requires prompt treatment to prevent vision problems. Read on as Vision Solutions, your go-to eye care clinic, discusses the different types of glaucoma:

Wide-Angle (Open-Angle)

Your eyes contain fluids that are drained into the trabecular meshwork located in the angle formed between your iris and cornea. In wide-angle glaucoma, IOP increases even though the angle is unobstructed. This is the most common form of glaucoma. While you may not notice any visual changes at first, you may see dark spots across your visual field as the disease progresses.

Narrow-Angle (Angle-Closure)

Angle-closure glaucoma occurs when your eye fluids fail to drain correctly due to obstructions or structural irregularities blocking the angle between your iris and cornea. You may experience severe headaches, blurry vision, and nausea. The narrow-angle form requires prompt glaucoma treatment to prevent sudden vision loss.

Low Pressure (Normal-Tension)

Normal-tension glaucoma is a unique form of the disease in which your optic nerve becomes compressed even though your IOP level remains within the normal range of 12-22 mm Hg. It is usually caused by blood flow problems in your eyes.


Congenital or childhood glaucoma is a rare form of glaucoma that is usually diagnosed within the first year of life. It is typically an inherited condition that inhibits your eyes’ ability to drain fluids, resulting in high IOP.

We typically prescribe IOP-lowering eye drops to manage early-stage glaucoma. For more severe cases, we may suggest conventional or laser surgery to increase the flow of your eye fluids, remove obstructions, or correct structural infirmities.
