Glaucoma Eye Exams in Danville

Applanation tonometry is a test used to detect changes in eye pressure. This type of tonometry test is the most common and considered the most accurate for measuring eye pressure.

Because glaucoma detection is related to eye pressure changes, applanation tonometry is an effective method of diagnosis.

The Perkins tonometer is a device that helps detect intraocular pressure (IOP) in a patient’s eyes while seated or standing. This form of glaucoma diagnosis is not as common as applanation tonometry but allows our team to perform IOP measurements.

Threshold visual fields is a test that allows us to evaluate the actual optic nerve and a patient’s peripheral vision. Glaucoma reduces one’s peripheral vision and this test allows us to monitor the progression over time.

OCT uses light to evaluate the thickness of the nerve fiber layer and the neural retinal rim of the optic nerve.

It’s highly sensitive and, when used with the threshold visual field machine, can track glaucoma progression accurately. It’s also great for those who cannot perform the visual field due to age or physical inability.

This machine allows us to determine the thickness of the cornea which is a risk factor in all types of glaucoma.
