In some instances, additional ancillary testing is important in taking care of your eyes. Your doctor will let you know if this is the case. At Silicon Valley Eyecare, we actively use and invest in the best technology for the diagnosis and management of ocular issues. Pictured below is a sampling of our advanced instrumentation.

Zeiss Atlas Corneal Topography
Corneal topography uses an illuminated ring pattern to map the surface curvatures of the cornea like a topographic map. Highly elevated or steeply curved portions of the cornea are coded in reddish colors. Less steep areas are coded in bluish colors. Your doctor will use the precise measurements from the topographer as well as the overall topographic map that it generates to understand the 3D architecture of your cornea. This information is important for diagnosing keratoconus and other corneal degenerations, as well as for the custom fitting of precise contact lenses such as CRT overnight therapy lenses.

Optical Coherance Tomography (OCT)
Optical Coherance Tomography (OCT) is at the forefront of eyecare technology, and SVE is one of the few optometric offices that proudly owns and operates this cutting-edge instrumentation using spectral domain technology.

OCT is a non-invasive imager that can visualize the tissue within the eye to a resolution of 5-15 um. This ultra-detailed view of the eye means that single anatomical layers within the retina can be differentiated and retinal thickness can be measured, thus allowing the doctor to detect suspected problems when they are invisible to the unassisted eye and to other diagnostic instruments.

The OCT is used to identify and track the minute progression of holes, fluid accumulation, tumors, and retinal disorders over time – before and after treatment.

The OCT is different from an optomap retinal imager. The optomap also takes a highly detailed image of the retina, but it is a global view. The OCT provides even more detail of specific targeted areas.

Zeiss Visucam Photography
The Visucam takes photographs of the eye in high magnification and true color. It is focused on anatomical areas of interest within the eye for a high resolution picture of that specific, targeted area. This camera is different from the optomap retinal imager, which takes an overall, global image of the retina that can be separated in 2 layers. You may need to have your pupils dilated for best results with the Visucam.

This specialty test is important for monitoring chronic conditions that may change over time. The photograph documents the size, shape, coloring, and pattern of problems such as hemorrhages, pigmented lesions, vascular lesions, elevation, fluid leakage, and growths. Sequential photographs taken over a span of time, along with careful monitoring at office visits, will help identify subtle amounts of change which may require further medical intervention.

Humphrey Visual Field Analyzer
The Humphrey Visual Field Analyzer quantifies the sensitivity of your visual perception within your central and peripheral vision. It is used for detecting losses in your field of view that may be related to eyelid issues, neural pathway issues, vascular issues, and neural tissue damage. The Humphrey Visual Field Analyzer is also the world’s gold standard for detecting glaucomatous neuropathies.

To take this test, is is critical that patients pay careful attention to the instructions that your tester will provide. You may be given a near prescription to look through while taking the test, and you may feel tired afterwards.

Color Vision
Acquired color vision changes are important markers for detecting active damage and disease processes within the eye. There are many methods for measuring color deficiencies, ranging from simple to complicated. Depending on your ocular needs, your doctor will determine which test is best suited for you. Please remember to notify your doctor if you work with lasers, have a family history of color blindness, or have perceived a difference in color detection between your eyes.
