The 4 Major Glaucoma Classifications

by Jamie Peters

Glaucoma results from a build-up of fluid in your eyes, which leads to increased intraocular pressure (IOP) that can cause optic nerve compression. Your optic nerve is responsible for carrying visual signals to the brain for interpretation, so any damage to it can impair your vision.

If left untreated, glaucoma can eventually lead to vision loss. In today’s post, your eye doctors at Vision Solutions discuss the four major types of glaucoma and our recommended eye care in La Mesa, CA.

1. Primary Open-Angle Glaucoma (Wide-Angle)

Your eye fluid drains through a spongy mesh channel, which can be found at an angle between the iris and cornea. When this opening becomes blocked, fluid will accumulate, leading to high IOP levels that can eventually cause optic nerve compression and damage.

This is the most common form of glaucoma. Although asymptomatic in its early stages, you may notice blank spots in your vision as the condition advances. We may prescribe eye drops to reduce ocular pressure, or surgery to prevent the condition from progressing.

2. Angle-Closure Glaucoma (Narrow-Angle)

This happens when the angle between the cornea and iris becomes restricted, leading to inefficient eye fluid drainage. This may cause pupil dilation, headaches, and vision blurring. You may also experience nausea and eye pain. If you notice any of these symptoms, we suggest seeing our eye experts immediately.

3. Normal-Tension Glaucoma (Low-Pressure Glaucoma)

With this form of glaucoma, the IOP remains within the normal range (12-22 mmHg), yet signs of optic nerve compression still manifest. Although the root cause remains unknown, glaucoma treatment in La Mesa, CA, helps keep the IOP at low levels to prevent vision loss.

4. Congenital Glaucoma

Congenital glaucoma occurs when an incomplete or incorrect development of certain components of your eyes causes an angular defect. This may lead to fluid overload and increased IOP. We may recommend microsurgery to manage this problem.For premier eye care services, you can turn to Vision Solutions.
