Offering The Most Advanced Technologies in Glaucoma Diagnosis

HRT (Heidelberg Retinal Topography

HRT technology makes it possible to diagnose glaucoma earlier than with standard optic nerve photography and clinical examination. This computerized technology provides a computerized three-dimensional map of the optic nerve to diagnose early-stage optic nerve changes and thinning of the optic nerve rim.  This technology also makes it easier to detect a change or progression in the optic nerve earlier than by clinical exam or standard photography.

Sita Visual Field Testing and Progression Analysis

The Sita Humphrey Visual Field Analyzer is the latest prototype of visual field technology to detect early loss of peripheral vision associated with glaucoma. Both the Sita Standard and Sita Fast modalities are available, to allow more accurate detection of the earliest changes in peripheral (side) vision that can occur with glaucoma. The newest statistical progression analysis allows us to detect peripheral vision loss earlier and more accurately, so that glaucoma treatment can be increased or enhanced if needed.

Digital Stereoscopic Optic Nerve Photography

We have the most advanced digital camera currently available to obtain stereoscopic photographs of the optic nerve. These photographs can be viewed immediately on our digital computer screen and are still considered the gold standard in optic nerve evaluation. They document the appearance of the optic nerves and make it possible to observe any subtle changes in the nerves that can occur at the start of or with progression of glaucoma. This digital technology also allows us to immediately compare the appearance of the optic nerve to previous photographs to make sure the optic nerve is stable and its condition has not worsened.

Corneal Pachymetry

This ultrasound device quickly and accurately measures the thickness of the cornea. Research has shown that eye pressure measurements are related to corneal thickness. If the cornea is very thin, the true intraocular pressure is higher than what is actually measured, and a very thick cornea indicates that the true eye pressure is lower than what is actually measured. Corneal pachymetry is therefore extremely important in accurately determining eye pressure.

Gonioscopy 

This special four mirror instrument is placed on the anesthetized eye to determine if the angles are open, narrow, or closed. This instrument makes it possible to accurately diagnose which type of glaucoma (open-angle or angle-closure) the patient has. Gonioscopy can also detect critically narrow angles that require a laser peripheral iridotomy to prevent angle closure glaucoma from occurring.

Star II Glaucoma Risk Calculator

Extensive research on ocular hypertensives (patients with high pressure but no other signs of glaucoma) has given us the data that makes it possible to determine a patient’s five year risk for glaucoma. The elevated eye pressure measurement, as well as other diagnostic test results, are entered into a special risk calculator. When the calculator indicates that the five year risk for glaucoma development is less than 5%, the patient can be safely watched and does not require treatment. Treatment is considered if the risk is between 5% and 15%, although many patients at this moderate risk level can also be safely watched. If the risk for glaucoma development is greater than 15%, the patient is considered to be a high risk and treatment is usually initiated to lower eye pressure.

Optical Coherence Tomography

Optical coherence tomography (OCT) is a non-invasive imaging test that uses light waves to take cross-sectionpictures of your retina, the light-sensitive tissue lining the back of the eye. With OCT, each of the retina’s distinctive layers can be seen, allowing to map and measure their thickness. These measurements help with diagnosis and provide treatment guidance for glaucoma and retinal diseases, such as age-related macular.

Diopsys® ERG Contrast Sensitivity

Designed to provide data to aid in the diagnosis and care of diseases that affect the retina in a diffuse pattern like Chronic Open Angle Glaucoma (COAG) and Diabetic Retinopathy (DR). Since there is typically no specific topographic pattern of damage, the information collected using this protocol may help in detecting the depth of the macular dysfunction.

Ultrasound Biomicroscopy / B-scan 

Ultrasonography is a type of ultrasound eye exam that makes a more detailed image ultrasound. High-energy sound waves are bounced off the inside of the eye and the echo patterns are shown on the screen in a two-dimensional, cross-sectional view of the eye and the orbit. 

Corneal Topography

Corneal topography, also known as photokeratoscopy or videokeratography, is a non-invasive medical imaging technique for mapping the surface curvature of the cornea, the outer structure of the eye. Since the cornea is normally responsible for some 70% of the eye's refractive power, its topography is of critical importance in determining the quality of vision and corneal health.
