After cataracts, glaucoma is the second leading cause of blindness. It is caused when elevated pressure in the eye damages the optic nerve, which carries visual information to the brain. Glaucoma can be very dangerous because by the time symptoms start to emerge, the disease has already been progressing for a while. That’s why the best way to prevent glaucoma is to schedule a regular eye appointment with an optometrist. If you suspect that you have glaucoma, below are some common eye tests that your provider may perform.
 

1. OPTHALMOSCOPY TEST

An ophthalmoscopy test examines the inside of the eye, particularly the back of it. The optometrist will use a magnifying lens called a phthalmoscope, or funduscope, to shine a non-harmful beam of light into your eye. He or she will then study the color, shape and overall health of the optic nerve.
 

2. TONOMETRY TEST

A tonometry test measures the pressure inside the eye, called the “intraocular pressure”. The optometrist will lightly touch the surface of the eye to measure its resistance. Note that it’s possible to have high eye pressure, and no glaucoma; or to have glaucoma despite having low eye pressure. Therefore, a tonometry test does not measure whether there is high eye pressure, but whether that pressure constantly fluctuates up and down.
 

3. GONOISCOPY TEST

A gonoiscopy test examines the area between the cornea and the iris where fluid drains out of the eye, called the drainage angle. The optometrist will use a mirrored device to gently touch the surface of the eye and determine if the drainage angle is open or closed. The condition of the drainage angle can indicate whether or not glaucoma is present, and how severe it might be.
 

4. NERVE FIBER ANALYSIS

A nerve fiber analysis is a newer type of glaucoma test which measures the thickness of the nerve fiber layer. Thinner optic nerve fibers may indicate glaucoma damage. This is a particularly good test to determine if a patient’s glaucoma is progressively worsening.
 

5. PACHYMETRY TEST

A pachymetry test measures the thickness of the cornea, as recent research indicates that thin corneas might be an indicator of glaucoma. Knowledge of corneal thickness is also important when determining if a patient is a candidate for refractive surgical procedures, such as LASIK. During a pachymetry test, your eye doctor will a device that looks similar to a thermometer, called a pachymeter, to measure the corneas without touching them. Ultrasound pachymetry, as the name implies, uses an ultrasound device to measure the cornea thickness.
