Diagnostic testing is a large asset to your physician. These tests assist your doctor in confirmation of a suspected problem, and watch for changes in your condition. In some cases the tests may indicate a need for surgical correction. We perform diagnostics daily, and these are the more notable ones.
Ocular Coherence Tomography (OCT)
This is newer technology that allows a physician to look at the tissue health of the eye (retinal fiber layer). This instrument will compare your scans against previously collected statistics. It will show where you fall within those guidelines, and if there is need for concern. The first scan is the baseline, and will be the starting reference which other scans will be compared to. This test is used routinely for glaucoma patients, but is also valuable for retina problems.
Visual field testing has been around many years, and has gone through several advances. Today`s tests are automated and performed more quickly. This is a subjective test that shows us what the patient is actually able to see, and where there may be some vision loss. It is performed routinely for glaucoma patients, but is also valuable for other issues as well.
Photography is utilized for internal and external conditions. Internal photography is used for documenting retinal conditions and optic nerve issues. External photos are used for a multitude of reasons, but mostly for documenting lid conditions. Fluorescein Angiograms take photography a step further with a dye injection. This gives the physician information about circulation as well as highlighting problematic areas.
This test is similar to a land elevation map. Topography is used to map the surface of the cornea. It will show where there are high and low areas indicating amounts of astigmatism, its location, and severity.
In order to perform a successful cataract surgery, your physician needs extra information that a routine examination doesn`t provide. The above mentioned topography will be used along with an A scan and keratometry readings. The A scan will give information regarding the length of the eye, and the keratometry will show shape of the eye along with astigmatism details.
