AUTOMATED VISUAL FIELDS
Visual field tests assess the potential presence of blind spots (scotomas), which could indicate eye diseases. A blind spot in the field of vision can be linked to a variety of specific eye diseases, depending on the size and shape of the scotoma. Many eye and brain disorders can cause visual field abnormalities. For example, optic nerve damage caused by glaucoma creates a very specific visual field defect. Other vision problems associated with blind spots developing within the visual field include optic nerve damage from disease or toxic exposure or damage to the light-sensitive inner lining of the eye (retina). Brain abnormalities such as those caused by strokes or tumors can affect the visual field. In fact, the location of the stroke or tumor in the brain can frequently be determined by the size, shape, and site of the visual field defect.
We are pleased to offer retinal photography as part of your routine office examination. The photography will produce the most comprehensive image of your retina, and allow the doctor to perform a more thorough exam than was previously possible.
Any routine eye exam should always include a careful look at the retina, which is located at the back of the eye, to assess for abnormalities or disease. The sensitive tissue that makes up the retina is susceptible to a variety of diseases that can ultimately lead to partial loss of vision or even complete blindness. Early detection of any retinal abnormality is crucial.
The result is that we can better prevent or reduce vision loss in our patients with a simple, quick and patient-friendly new technology, now and in the future.
A pachymetry test is a simple, quick, painless test to measure the thickness of your cornea. With his measurement, your doctor can better understand your IOP reading, and develop a treatment plan that is right for your condition. The procedure takes only about a minute to measure both eyes.
This test is performed on patients who have glaucoma or when the disease is suspected a special mirrored contact lens is used to allow the doctor to examine the structures in the front of the eye. With this lens, the doctor can assess the eye’s drainage system.
Of all the technology currently available, corneal topography provides the most detailed information about the curvature of the cornea. Using a very sophisticated computer and software, thousands of measurements are taken and analyzed in just seconds. The computer generates a color map from the data. This information is useful to evaluate and correct astigmatism, monitor corneal disease, and detect irregularities in the corneal shape.
RETINAL OCT (Optical Coherence Tomography)
The OCT has been invaluable in diagnosing patients with many macular disorders. I would like to give you an introduction to OCT and some of our patient surgical outcomes. OCT does a direct cross-sectional retinal image of the retina. (In particular the macula, the center of the retina.) It can be compared to using an X-ray when diagnosing a broken arm. Direct cross-sectional imaging enables the doctor to look at a “cutaway” view of each layer of the retina and optic nerve and accurately assess their characteristics. From one visit to the next we can see if your eye has improved or deteriorated.
CORNEA-ANTERIOR SEGMENT OCT
The OCT provides an unprecedented level of detail for our doctors. We can think of that detail as a microscopic view of a forest. Topography and other technologies based on reflected light provide only a macroscopic view, the umbrella of leaves at the top of the forest. But OCT customized for the anterior segment allows us to actually look at the leaves. As a result, we are able to see things we were unable to see before.
