Glaucoma Testing & Management

Testing for Glaucoma Could Save Your Vision

A regular eye exam could save your eyesight. Glaucoma is characterized by a gradual loss of peripheral vision without any pain. However, the onset of this eye disease is so slow it often begins to take effect without any noticeable symptoms. So how do you stop a disease that you can’t even tell is there?

Gradual Glaucoma

The symptoms of glaucoma are evident to your optometrist in a number of ways, making regular eye exams critical to your eye health. They can detect the early signs like ocular hypertension, or high eye pressure. If this pressure is left untreated it can can damage the optic nerve, resulting in glaucoma.

The key to detection is testing your intraocular pressure, or IOP and examining your optic nerve. One of the ways we test the pressure is with non-contact tonometry, or the air puff test. We use air to flatten your corneas and measure the force of the air bouncing back. This test is not conclusive, but gives the optometrist a good idea of your IOP.

The other method we use to test your intraocular pressure is applanation tonometry. This is a much more accurate test, measuring the force needed to push the cornea down. The more pressure in your eyes the more force it takes to affect the eye. Your optometrist will know which test is needed to accurately measure your IOP.

Types of Glaucoma

This type of glaucoma is the most severe and needs immediate attention by a healthcare practitioner.

Acute angle-closure glaucoma is a sudden medical emergency that occurs when the angle between the cornea and iris suddenly closes, and the fluid in the eye can’t drain appropriately. This lack of drainage causes your eye pressure to rise, damaging your optic nerve. This form of glaucoma causes headaches, nausea, and vomiting as well as blurred vision and red eyes. If you experience these symptoms, seek help immediately.

Open-angle glaucoma has no initial symptoms and results in gradual loss of peripheral vision. This loss of side sight is extremely difficult to notice, even over several years. Often, vision loss is detrimental and irreversible before it is obvious.

This disease is caused by too much fluid in the eye being produced or not enough being drained , increasing the eye pressure and causing damage to the optic nerve. Age, diabetes, and cardiovascular disease increase your risk of open-angle glaucoma.

Normal tension glaucoma is a variation of this disease that remains a mystery to doctors. Vision loss occurs and the optic nerve shows signs of damage without an increase in intraocular pressure. The aqueous humor flows properly, the drainage canals function as they should, and the intraocular pressure is within a normal range.

Glaucoma Treatment

Glaucoma does not have a cure, but there are methods to treat it. A combination of eye drops, and oral medication is often the most effective. If the disease does not respond to these treatments there laser surgery to increase drainage can help lower the ocular hypertension that contributes to glaucoma.
