Special Testing

At AccuVision Optical we are committed to using the latest technology in optometric care. In order to ensure that you maintain the best possible eye health and vision, we have some of the most advanced diagnostic equipment in our office.

Note:  Although, these tools are highly valuable in diagnosing many eye health and vision problems, the fees associated with most of these tests are only covered by medical insurance in select cases, and they are generally not covered by vision insurance.

Auto-Refractor

The Auto-refractor is a computer-controlled instrument used to provide an objective measurement of a person’s refractive error and prescription for glasses and contact lenses. This may be used as the starting point for the doctor to determine the best prescription for you. Automated refraction is particularly useful for young children or those with disabilities.

We use the auto-refractor on nearly every patient during their annual comprehensive eye exam and there is no additional fee.

FDT (Frequency Doubling Technology)

The FDT is an instrument designed for fast and effective screening of visual field loss. It can determine if you have lost the ability to see in a specific viewing area (i.e. a segment of your peripheral vision or central vision). It assists us with detection of early glaucoma, and in other disorders of the visual system that may not be visible during a normal exam.

We recommend an FDT test to all of our patients during their comprehensive eye exam because it is a quick and easy way to screen for many significant eye health issues. It’s non-invasive and takes about 5-minutes to perform.

OCT – Optical Coherence Tomography

OCT is an advanced diagnostic tool generally used in ophthalmology offices. It is a non-invasive technology used for imaging the retina (the multi-layered sensory tissue lining the back of the eye). OCT is the first instrument to allow doctors to see cross-sectional images of the retina. It is revolutionizing the early detection and treatment of eye conditions such as macular holes, pre-retinal membranes, macular swelling and optical nerve damage. It is particularly useful in the diagnosis and treatment of glaucoma and macular degeneration.

If you are a candidate for an OCT, the doctor will ask you to schedule a suitable time to conduct the test, which generally takes around 10 minutes to perform. To achieve optimal results, you may need to have your pupils dilated.

Pachymeter

The pachymeter is used to measure the thickness of the cornea (the clear covering over the front surface of the eye). It is used prior to LASIK surgery, for Keratoconus or other corneal dystrophy monitoring, and is beneficial in screening patients suspected of developing glaucoma. Our modern version uses ultrasound technology (earlier models were based on optical principles).

If you are a candidate for pachymetry, the doctor will ask for you to schedule a suitable time to conduct the test which generally takes less than 5 minutes to perform. You do not need to have your pupils dilated for pachymetry.

Retinal Camera

Retinal photography assists in the detection and management of problems such as diabetic changes, hypertensive retinopathy, macular degeneration, optic nerve disease and retinal holes or thinning. This test is especially important for people with a history of high blood pressure, diabetes, retinal diseases, headaches, or a strong glasses prescription.

A fundus or retinal camera is a specialized low power microscope with an attached camera designed to photograph the interior surface of the eye. The camera is used to monitor the progression of disease, diagnosis disease, or in screening programs, where the photos can be analyzed later.

Every comprehensive eye exam should include an evaluation of the retina. Digital retinal imaging is our preferred method of retinal evaluation since it allows for comparison over time, analysis with computer software, and shows you what the doctor is examining.

If you are a candidate for retinal imaging we will either take your photos during your exam or ask you to schedule another time.  This test generally takes around 10 minutes to perform. To achieve optimal results, you may need to have your pupils dilated.

VF (Visual Field Testing)

A visual field test is a method of measuring an individual’s entire scope of vision, including their central and peripheral (side) vision.

Visual field testing is most frequently used to detect and follow any loss of vision due to glaucoma damage. In addition, visual field tests are useful for detection of central or peripheral retinal disease, eyelid conditions such as ptosis or drooping, optic nerve disease, and diseases affecting the visual pathways within the brain.

If you are a candidate for a visual field test, the doctor will ask for you to schedule a suitable time to conduct the test.  The length of time for a VF test can vary widely depending on the suspected issue. They can range from 10 to 30 minutes to perform.

You generally do not need to have your pupils dilated for a visual field test.
