Diagnosis of Glaucoma at The Eye Center of Colorado in Denver

In order to preserve your eye health and vision, we recommend that you have eye examinations with the appropriate level of diagnostic testing for Glaucoma. During your examination, the doctors and staff at The Eye Center in Denver will perform a number of tests in order to make the most accurate diagnosis of Glaucoma. These may include the following testing procedures:

Tonometry

The Tonometry Test is a method of measuring your Intraocular Pressure (IOP). This test involves first placing some eye drops into your eyes to numb them and then lightly touching the surface of the cornea with a specialized measuring instrument. There is no discomfort involved. The test is quick and gives the eye doctors the first piece of important information in determining whether you have Glaucoma.

Ophthalmoscopy

Ophthalmoscopy is a method of carefully examining the inside of the eye-especially the optic nerve-in order to detect Glaucoma. Some eye drops will be placed in your eyes in order to dilate your pupils so that the doctors can make a clear and direct observation of the optic nerve. The examination will take place in a darkened room using different types of Ophthalmoscopes in order to examine the shape and color of your optic nerve.

If either your Intraocular Pressure (IOP) is elevated or your optic nerve appears unusual, additional tests will be necessary in order to complete the Glaucoma examination. These may include the following test procedures: 

Visual Field Perimetry

Perimetry or Visual Field testing is an important part of the Glaucoma examination. During this test you will be asked to sit in front of a large “bowl like” instrument and look directly straight ahead. A computer program will present a number of lights in different positions of your “side” or peripheral vision to see how far your side vision extends in various directions. The computer will then plot an actual map of your field of vision so that the doctors can interpret this map in conjunction with other examination tests in order to understand how well your optic nerve is functioning.

Gonioscopy

Gonioscopy is a quick and painless test that allows the doctos to directly observe the health and condition of the angle where the iris meets the cornea. By directly observing the angle and its status the doctors will know more about whether you are at risk for the angle to become closed or whether the Trabecular Meshwork appears to have a normal anatomical structure.

Optic Nerve Computer Imaging

At The Eye Center, we use the advanced computer imaging technology in order to make the earliest and most accurate diagnosis of Glaucoma. Our Optic Nerve Computer Imaging system is called the Zeiss Cirrus Optic Nerve Head Analysis.

The Zeiss Cirrus Optic Nerve Head Analysis uses an imaging method called “confocal laser ophthalmoscopy” to scan the retinal surface and optic nerve with a laser. It then constructs a topographic three dimensional (3-D) image of the optic nerve and measures the thickness of the retinal nerve fiber layer. These are very precise measurements that your eye doctor will interpret in conjunction with the other Glaucoma tests at your examination.

The goal of the Zeiss Cirrus Optic Nerve Head Analysis Imaging is to give the eye doctors the ability to detect the slightest loss of optic nerve fibers, at the first possible moment, in order to diagnose Glaucoma at the earliest possible stage in order to stop the progression of the disease and preserve your vision.

Pachymetry Measurement of Corneal Thickness

The National Eye Institute of the National Institutes of Health released a key study in 2002, called the Ocular Hypertension Study (OHTS). In this study an important finding was made regarding corneal thickness and its role in Intraocular Pressure and the development of Glaucoma.

The OHTS study found that corneal thickness is important because it can alter the accuracy of the measurement of Intraocular Pressure. Your actual Intraocular Pressure may be UNDERESTIMATED if you have thin corneas and it may be OVERESTIMATED if you have thicker corneas.

During your Glaucoma examination, your doctor or a staff member may perform a Pachymetry Test to measure your corneal thickness as part of your examination and consider this finding in conjunction with the other Glaucoma testing in order to make the most accurate diagnosis.

The Pachymetry Test is a simple, quick and painless way of accurately measuring your coneal thickness that we do right in our office. The test is performed by first placing some drops in your eyes to make them numb and then lighty touching the cornea with a “pencil like” probe that uses sound waves to precisely measure your corneal thickness.

Glaucoma is a very complex eye disease, and not simply an elevated Intraocular Pressure (IOP). Nonetheless, when detected early it can be successfully treated. The Eye Center provides comprehensive testing, diagnosis and treatment of Glaucoma.

The Eye Center is conveniently located for patients requiring testing and diagnosis of Glaucoma from Denver, Aurora, Arvada, Wheat Ridge, Westminster, Commerce City, Englewood, Littleton, Sheridan, Cherry Hills Village, Northglenn, Broomfield and Greenwood Village.
